must be fitted and controlled by work procedures, so that one
machine cannot accidently be pressurised / over pressurised by
another.

Make sure that all protective covers are in place and that the
canopy/doors are closed during operation.
The specification of this machine is such that the machine is
not suitable for use in flammable gas risk areas. If such an
application is required then all local regulations, codes of
practice and site rules must be observed. To ensure that the
machine can operate in a safe and reliable manner, additional
equipment such as gas detection, exhaust spark arrestors, and
intake (shut–off) valves may be required, dependant on local
regulations or the degree of risk involved.

Compressed air must not be used for a direct feed to any
form of breathing apparatus or mask.
High Pressure Air can cause serious injury or death. Relieve
pressure before removing filler plugs/caps, fittings or covers.

A weekly visual check must be made on all fasteners/fixing
screws securing mechanical parts. In particular, safety–related
parts such as coupling hitch, drawbar components,
road–wheels, and lifting bail should be checked for total
security.

Air pressure can remain trapped in air supply line which can
result in serious injury or death. Always carefully vent air supply
line at tool or vent valve before performing any service.
The discharged air contains a very small percentage of
compressor lubricating oil and care should be taken to ensure
that downstream equipment is compatible.

All components which are loose, damaged or unserviceable,
must be rectified without delay.
Air discharged from this machine may contain carbon
monoxide or other contaminants which will cause serious injury
or death. Do not breathe this air.

If the discharged air is to be ultimately released into a
confined space, adequate ventilation must be provided.

This machine produces loud noise with the doors open or
service valve vented. Extended exposure to loud noise can
cause hearing loss. Always wear hearing protection when doors
are open or service valve is vented.

When using compressed air always use appropriate
personal protective equipment.
All pressure containing parts, especially flexible hoses and
their couplings, must be regularly inspected, be free from
defects and be replaced according to the Manual instructions.

Never inspect or service unit without first disconnecting
battery cable(s) to prevent accidental starting.

Avoid bodily contact with compressed air.

Do not use petroleum products (solvents or fuels) under high
pressure as this can penetrate the skin and result in serious
illness. wear eye protection while cleaning unit with compressed
air to prevent debris from injuring eye(s).

The safety valve located in the separator tank must be
checked periodically for correct operation.

7/170 (P600WIR), 10/125 (HP450WIR), 14/115 (VHP400WIR)

Whenever the machine is stopped, air will flow back into the
compressor system from devices or systems downstream of
the machine unless the service valve is closed. Install a check
valve at the machine service valve to prevent reverse flow in the
event of an unexpected shutdown when the service valve is
open.

Battery

Disconnected air hoses whip and can cause serious injury
or death. Always attach a safety flow restrictor to each hose at
the source of supply or branch line in accordance with OSHA
Regulation 29CFR Section 1926.302(b).

DO NOT ATTEMPT TO SLAVE START A FROZEN BATTERY
SINCE THIS MAY CAUSE IT TO EXPLODE.

A battery contains sulphuric acid and can give off gases
which are corrosive and potentially explosive. Avoid contact
with skin, eyes and clothing. In case of contact, flush area
immediately with water.

Exercise extreme caution when using booster battery. To
jump battery, connect ends of one booster cable to the positive
(+) terminal of each battery. Connect one end of other cable to
the negative (–) terminal of the booster battery and other end to
a ground connection away from dead battery (to avoid a spark
occurring near any explosive gases that may be present). After
starting unit, always disconnect cables in reverse order.

Never allow the unit to sit stopped with pressure in the
receiver–separator system.

Before towing the machine, ensure that:–

Consult a physician if large amounts of compressor lubricant
are ingested.

. the tyres and towing hitch are in a serviceable condition.
. the canopy is secure.
. all ancillary equipment is stored in a safe and secure manner.
. the brakes and lights are functioning correctly and meet
necessary
road traffic requirements.
. break-away cables/safety chains are connected to the
towing
vehicle.

Consult a physician if compressor lubricant is inhaled.
Never give fluids or induce vomiting if the patient is
unconscious or having convulsions.
Safety data sheets for compressor and engine lubricants
should be obtained from the lubricant supplier.

The machine must be towed in a level attitude in order to
maintain correct handling, braking and lighting functions. This
can be achieved by correct selection and adjustment of the
vehicle towing hitch and, on variable height running gear,
adjustment of the drawbar.

Never operate the engine of this machine inside a building
without adequate ventilation. Avoid breathing exhaust fumes
when working on or near the machine.

To ensure full braking efficiency, the front (towing eye)
section must always be set level.
When adjusting variable height running gear:–

Ensure front (towing eye) section is set level

Where brakes only are fitted:

When raising towing eye, set rear joint first, then front joint.

a) Ensure that the breakaway cable is securely coupled to the
handbrake lever and also to a substantial point on the towing
vehicle.

When lowering towing eye, set front joint first, then rear joint.

b) Ensure that the effective cable length is as short as possible,
whilst still allowing enough slackness for the trailer to articulate
without the handbrake being applied.
Where brakes and safety chains are fitted:

After setting, fully tighten each joint by hand and then tighten further to the next pin. Refit the pin.

a) Loop the chains onto the towing vehicle using the towing
vehicle hitch as an anchorage point, or any other point of similar
strength.
When parking always use the handbrake and, if necessary,
suitable wheel chocks.

b) Ensure that the effective chain length is as short as possible
whilst still allowing normal articulation of the trailer and effective
operation of the breakaway cable.

Make sure wheels, tyres and tow bar connectors are in safe
operating condition and tow bar is properly connected before
towing.

Where safety chains only are fitted:
a) Loop the chains onto the towing vehicle using the towing
vehicle hitch as an anchorage point, or any other point of similar
strength.

Safety chains / connections and their adjustment

b) When adjusting the safety chains there should be sufficient
free length in the chains to allow normal articulation, whilst also
being short enough to prevent the towbar from touching the
ground in the event of an accidental separation of the towing
vehicle from the trailer.

The legal requirements for the joint operation of the
breakaway cable and safety chains are as yet unidentified by
71/320/EEC or UK regulations. Consequently we offer the
following advice / instructions.

OPERATING INSTRUCTIONS

PRIOR TO STARTING

5. Drain the fuel filter water separator of water, ensuring that
any released fuel is safely contained.

1. Place the unit in a position that is as level as possible. The
design of the unit permits a 15 degree lengthways and sideways
limit on out of level operation. It is the engine, not the
compressor, that is the limiting factor.

6. Open the service valve(s) to ensure that all pressure is
relieved from the system. Close the service valve(s).

When the unit has to be operated out of level, it is important
to keep the engine oil level near the high level mark (with the unit
level).

7. CAUTION: Do not operate the machine with the
canopy/doors in the open position as this may cause
overheating and operators to be exposed to high noise levels.

CAUTION: Do not overfill either the engine or the compressor
with oil.
8. Check the radiator coolant level (with the unit level).
2. Check the engine lubrication oil in accordance with the
operating instructions in the Engine Operator’s Manual.

Check the air restriction indicator(s). Refer to the
MAINTENANCE section of this manual.

3. Check the compressor oil level in the sight glass located on
the separator tank.

When starting or operating the machine in temperatures
below or approaching 0C, ensure that the operation of the
regulation system, the unloader valve, the safety valve, and the
engine are not impaired by ice or snow, and that all inlet and
outlet pipes and ducts are clear of ice and snow.

4. Check the diesel fuel level. A good rule is to top up at the end
of each working day. This prevents condensation from
occurring in the tank.

CAUTION: Use only a No. 2–D diesel fuel oil with a minimum
octane number of 45 and a sulphur content not greater than
0,5%.
CAUTION: When refuelling:–
. switch off the engine.
. do not smoke.
. extinguish all naked lights.

ENGINE

It has been found that bio–diesel fuels may
improve lubricity in concentrations up to a 5%
blend in petroleum diesel fuel.

Engine Serial Number Plate
Each engine has a 13–digit engine serial
number.

When using a blend of bio–diesel fuel, the
engine oil level must be check daily when the air
temperature is –10C (14F) or lower. If the oil
becomes diluted with fuel, shorten oil change
intervals accordingly.

The engine’s serial number plate is located on
the right–hand side of cylinder block behind the
fuel filter.

IMPORTANT: Raw pressed vegetable oils
are NOT acceptable for use for fuel in any
concentration.

Fuels, Lubricants, and Coolant
Diesel Fuel
Consult your local fuel distributor for properties
of the diesel fuel available in your area.

These oils do not burn completely, and will
cause engine failure by leaving deposits on
injectors and in the combustion chamber.

In general, diesel fuels are blended to satisfy
the low temperature requirements of the
geographical area in which they are marketed.

Handing and Storing Bio–Diesel Fuel
WARNING: Handle fuel carefully. Do not fill
the fuel tank when engine is running.

Diesel fuels specified to EN 590 or ASTM D975
are recommended.

DO NOT smoke while you fill the fuel tank or
service the fuel system.

Required fuel properties
In all cases, the fuel must meet the following
properties:

Fill the fuel tank at the end of each day’s
operation to prevent water condensation and
freezing during cold weather.

Cetane number of 45 minimum. Cetane
number greater than 50 is preferred, especially
for temperatures below –20C (–4F) or
elevations above 1500 m (5000 ft).

Keep all storage tanks as full as practicable to
minimize condensation.
Ensure that all fuel tank caps and covers are
installed properly to prevent moisture from
entering.

Cold Filter Plugging Point (CFPP) below the
expected low temperature OR Cloud Point at
least 5C (9F) below the expected low
temperature.

Monitor water content of the fuel regularly.
Fuel filter may require more frequent
replacement due to premature plugging.

Fuel lubricity should pass a minimum load
level of 3100 grams as measured by ASTM
D6078 or, maximum scar diameter of 0.45 mm
as measured by ASTM D6079.

Check engine oil level daily prior to starting
engine. A rising oil level may indicate fuel
dilution of the engine oil.

Sulfur content:
• Diesel fuel quality and fuel sulfur content must
comply with all existing regulations for the area
in which the engine operates.

When fuel is stored for an extended period or if
there is a slow turnover of fuel, add a fuel
conditioner to stabilize the fuel and prevent
water condensation. Contact your fuel supplier
for recommendations.

• Sulfur content less than 0.05% (500 ppm) is
preferred.

Diesel Fuel Storage

• If diesel fuel with sulfur content greater than
0.05% (500 ppm) is used, crankcase oil service
intervals may be affected. (See
recommendation for Diesel Engine Oil.)

WARNING: Handle fuel carefully. Do not fill
the fuel tank when engine is running.
DO NOT smoke while you fill the fuel tank or
service the fuel system.

• DO NOT use diesel fuel with sulfur content
greater than 1.0%.

Fill the fuel tank at the end of each day’s
operation to prevent water condensation and
freezing during cold weather.

IMPORTANT: DO NOT mix used engine oil or
any other type of lubricating oil with diesel
fuel.
Bio–Diesel Fuel
Bio–diesel fuels may be used ONLY if the
bio–diesel fuel properties meet the latest edition
of ASTM PS121, DIN 51606 or equivalent
specification.

7/120 (P425AWIR), 9/110 (XP375AWIR), 10/105 (HP375AWIR), 14/85 (VHP300AWIR),
7/170 (P600WIR), 10/125 (HP450WIR), 14/115 (VHP400WIR)

IMPORTANT: DO NOT store diesel fuel in
galvanized containers. Diesel fuel stored in
galvanized containers reacts with zinc
coating on container to form zinc flakes. If
fuel contains water, a zinc gel will also form.
The gel and flakes will quickly plug fuel
filters, damage injection nozzles and
injection pump.

Multi–viscosity diesel engine oils are
preferred.
Diesel fuel quality and sulfur content must
comply with all existing emissions regulations
for the area in which the engine operates.
If diesel fuel with sulfur content greater than
0.05% (500 ppm) is used, reduce the oil and
filter change interval by 100 hours.

DO NOT use brass–coated containers for
fuel storage. Brass is an alloy of copper and
zinc.

If diesel fuel with sulfur content greater than
0.5% (5000 ppm) is used, reduce the service
interval by 50%.

Store diesel fuel in plastic, aluminum, and steel
containers specially coated for diesel fuel
storage.

Diesel fuel with sulfur content greater than 1.0%
(10,000 ppm) is not recommended.

Avoid storing fuel over long periods of time. If
fuel is stored for more than a month prior to
use, or there is a slow turnover in fuel tank or
supply tank, add a fuel conditioner to stabilize
the fuel, prevent water condensation.
Minimizing the Effect of Cold Weather on
Diesel Engines
Ingersoll–Rand diesel engines are designed to
operate effectively in cold weather.
See your authorized engine distributor or
servicing dealer for additional information and
availability of cold weather aids.
Use Grade No. 1–D Fuel
When temperatures fall below 5C (40F),
Grade No. 1–D fuel is best suited for cold
weather operation.
Diesel Fuel Additive
IMPORTANT: Treat fuel when outside
temperature drops below 0_C (32_F). For
best results, use with untreated fuel. Follow
all recommended instructions on label.
Use a fuel conditioner (Winter) to treat fuel
during the cold weather season. Winter
formulation is a combination diesel fuel
conditioner and anti–gel additive.
Diesel Engine Oil
Use SAE15W–40 oil viscosity based on the
expected air temperature range of 10F to
122F (–12C–40C) during the period between
oil changes.
The following oil is preferred:
• Pro–Tec Engine Fluid
Other oils may be used if they meet one or
more of the following:
• API Service Classification CI–4
• API Service Classification CH–4
• ACEA Specification E3
• ACEA Specification E4
• ACEA Specification E5

7/170 (P600WIR), 10/125 (HP450WIR), 14/115 (VHP400WIR)

Diesel Engine Coolant

IMPORTANT: Only use coolant additive to
replenish the coolant. Do not use additive
when the entire system is drained and
refilled.

The engine cooling system is filled to provide
year–round protection against corrosion and
cylinder liner pitting, and winter freeze
protection to –37C (–34F).

Consult the coolant supplier and follow the
manufacturer’s recommendation for use of
supplemental coolant additives.

Low silicate ethylene glycol base coolants for
heavy–duty engines may be used if they meet
one of the following specifications:

The use of non–recommended supplemental
coolant additives may result in additive drop–out
and gelation of the coolant.

• ASTM D5345 (pre–diluted coolant)
• ASTM D4985 (coolant concentrate) in a 40 to
60% mixture of concentrate with quality water.

Add the manufacturer’s recommended
concentration of supplemental coolant additive.
DO NOT add more than the recommended
amount.

Coolants meeting these specifications require
use of supplemental coolant additives,
formulated for heavy–duty diesel engines, for
protection against corrosion and cylinder liner
erosion and pitting.

Coolant Drain Intervals
Drain the factory fill engine coolant, flush the
cooling system, and refill with new coolant after
the first 3 years or 3000 hours of operation.
Subsequent drain intervals are determined by
the coolant used for service. At each interval,
drain the coolant, flush the cooling system, and
refill with new coolant.

A 50% mixture of ethylene glycol engine coolant
in water provides freeze protection to –37C
(–34F). If protection at lower temperatures is
required, consult your dealer for
recommendations.
Water quality is important to the performance of
the cooling system. Distilled, or de–mineralized
water is recommended for mixing with ethylene
glycol base engine coolant concentrate.

Operating in Warm Temperature Climates
Ingersoll–Rand engines are designed to operate
using glycol base engine coolants.
Always use a recommended glycol base engine
coolant, even when operating in geographical
areas where freeze protection is not required.
IMPORTANT: Water may be used as coolant
in emergency situations only.
Foaming, hot surface aluminum and iron
corrosion, scaling, and cavitation will occur
when water is used as the coolant, even
when coolant conditioners are added.
Drain cooling system and refill with
recommended glycol base engine coolant
as soon as possible.

IMPORTANT: Do not use cooling system
sealing additives or antifreeze that contains
sealing additives.

Engine Break–In Service

Supplemental Coolant Additives

The engine is ready for normal operation.
However, extra care during the first 100 hours
of operation will result in more satisfactory
long–term engine performance and life. DO
NOT exceed 100 hours of operation with
break–in oil.

The concentration of coolant additives is
gradually depleted during engine operation. For
all recommended coolants, replenish additives
between drain intervals by adding a
supplemental coolant additive every 12 months.

inner and outer seals and to filter threads.

Daily Pre–starting Checks

6. Wipe both sealing surfaces of the header
with a clean rag. Ensure dust seal is in place,
replace if damaged.

Do the following BEFORE STARTING THE
ENGINE for the first time each day:
Check engine oil level on dipstick.

IMPORTANT: When installing filter element,
HAND TIGHTEN only. A filter wrench may be
used for REMOVAL ONLY.

IMPORTANT: DO NOT add makeup oil until
the oil level is BELOW the crosshatch marks
on the dipstick.

7. Install and tighten oil filter by hand until firmly
against dust seal. DO NOT apply an extra
3/4 to 1–1/4 turn after gasket contact as done
with standard filters.

IMPORTANT: DO NOT fill above the top mark
on the dipstick. Oil levels anywhere within
crosshatch are considered in the acceptable
range.

8. Tighten drain plug to specifications.

To change engine oil and oil filter:
Check the fuel filters for water or debris. If filter
is fitted with a see–through bowl, drain as
needed based on a daily visual inspection.

Specification

IMPORTANT: Drain water into a suitable
container and dispose of properly.

Oil Pan Drain Plug With Copper Washer—
Torque 70 N•m (52 lb ft)

a) Loosen drain plugs (A) at bottom of fuel filters
or bowls, if equipped, two or three turns.

Oil Pan Drain Plug With O–Ring—

To determine the correct oil fill quantity for your
engine, see ENGINE CRANKCASE OIL FILL
QUANTITIES in the Specifications Section of
this manual.

After draining water from the fuel filters, the
filters must be primed by bleeding all air from
the fuel system.

IMPORTANT: Immediately after completing
any oil change, crank engine for 30 seconds
without permitting engine to start. This will
help insure adequate lubrication to engine
components before engine starts.

Changing Engine Oil and Replacing Filter
Your engine is equipped with a special oil filter.
NOTE: During break–in, change engine oil and
filter for the first time before 100 hours
maximum of operation.

NOTE: Crankcase oil capacity may vary slightly.
ALWAYS fill crankcase within crosshatch marks
on dipstick. DO NOT overfill.

After break–in, the oil and filter change interval
is 500 hours or every 12 months, whichever
comes first.

10. Start engine and run to check for possible
leaks.

NOTE: If diesel fuel with a sulfur content
greater than 0.05% (500 ppm) is used, the oil
and filter change interval is reduced.
To change engine oil and oil filter:

11. Stop engine and check oil level after 10
minutes. Oil level reading should be within
crosshatch of dipstick.

1. Run engine approximately 5 minutes to warm
up oil. Shut engine off.

Cleaning Crankcase Vent Tube
If you operate the engine in dusty conditions,
clean the tube at shorter intervals.

2. Remove oil pan drain plug.
3. Drain crankcase oil from engine while warm.

1. Remove and clean crankcase vent tube.

4. Turn filter element using a suitable filter

Checking Belt Tensioner Spring Tension
and Belt Wear (Automatic Tensioner)

Engine is equipped with a primary fuel filter (or
pre–filter) with water bowl and a final filter. Both
filters are replaced at the same 500–hour
interval.

Belt drive systems equipped with automatic
(spring) belt tensioners cannot be adjusted or
repaired. The automatic belt tensioner is
designed to maintain proper belt tension over
the life of the belt. If tensioner spring tension is
not within specification, replace tensioner
assembly.

CAUTION: Escaping fluid under pressure
can penetrate the skin causing serious
injury. Relieve pressure before
disconnecting fuel or other lines. Tighten all
connections before applying pressure. Keep
hands and body away from pinholes and
nozzles which eject fluids under high
pressure. Use a piece of cardboard or paper
to search for leaks. Do not use your hand.

Checking Belt Wear
The belt tensioner is designed to operate within
the limit of arm movement provided by the cast
stops when correct belt length and geometry is
used.

1. Close fuel shut–off valve, if equipped.
2. Thoroughly clean fuel filter assemblies and
surrounding areas.

Visually inspect cast stops on belt tensioner
assembly.

3. Disconnect water sensor wiring (if equipped).

If the tensioner stop on swing arm is hitting the
fixed stop, check mounting brackets (alternator,
belt tensioner, idler pulley, etc.) and the belt
length. Replace belt as needed

4. Loosen drain plugs and drain fuel into a
suitable container.
NOTE: Lifting up on retaining ring as it is
rotated helps to get it past raised locators.

Checking Tensioner Spring Tension

5. Firmly grasp the retaining ring and rotate it
counterclockwise 1/4 turn. Remove ring with
filter element.
6. Inspect filter mounting base for cleanliness.
Clean as required.

A belt tension gauge will not give an accurate
measure of the belt tension when automatic
spring tensioner is used. Measure tensioner
spring tension using a torque wrench and
procedure outlined below:

NOTE: Raised locators on fuel filter canisters
must be indexed properly with slots in mounting
base forcorrect installation.

1. Release tension on belt using a breaker bar
and socket on tension arm. Remove belt from
pulleys.

7. Install new filter elements onto mounting
bases. Be sure elements are properly
indexed and firmly seated on bases. It may
be necessary to rotate filters for correct
alignment.

2. Release tension on tension arm and remove
breaker bar.
3. Put a mark on swing arm of tensioner as
shown.
4. Measure 21 mm (0.83 in.) and put a mark on
tensioner mounting base.

If equipped with water separator bowl (E),
remove filter element from separator bowl.
Drain and clean separator bowl. Dry with
compressed air. Install bowl onto new element.
Tighten securely.

5. Install torque wrench so that it is aligned with
centers of pulley and tensioner. Rotate the
swing arm using a torque wrench until marks
are aligned.

8. Align keys on filter element with slots in filter
base.

6. Record torque wrench measurement and
compare with specification below. Replace
tensioner assembly as required.

9. Install retaining ring onto mounting base
making certain dust seal is in place on filter
base. Hand tighten ring (about 1/3 turn) until
it “snaps” into the detent. DO NOT
overtighten retaining ring.

Specification
Spring Tension—Torque 18–22 N•m (13–16 lb–ft)

NOTE: The proper installation is indicated when
a ”click” is heard and a release of the retaining
ring is felt. A plug is provided with the new
element for plugging the used element.

NOTE: Threads on belt tensioner roller cap
screw are LEFT–HAND threads.
Checking Engine Electrical Ground
Connections

10. Reconnect water sensor wiring (if

Replenishing Supplemental Coolant
Additives (SCAs) Between Coolant Changes

3. Remove poly–vee belt from pulleys and
discard belt.

NOTE: If system is to be filled with coolant that
does not contain SCAs, the coolant must be
precharged.

4. Install new belt, making sure belt is correctly
seated in all pulley grooves. Refer to belt
routing at right for your application.

Through time and use, the concentration of
coolant additives is gradually depleted during
engine operation. Periodic replenishment of
inhibitors is required. The cooling system must
be recharged with additional supplemental
coolant additives available in the form of liquid
coolant conditioner.

5. Apply tension to belt with tensioner. Remove
socket.
6. Start engine and check belt alignment.
Bleeding the Fuel System
Bleed the Fuel System (Engines with Electronic
Fuel Systems and Stanadyne DE10 Pump)

Maintaining the correct coolant conditioner
concentration (SCAs) and freeze point is
essential in your cooling system to protect
against rust, liner pitting and corrosion, and
freeze–ups due to incorrect coolant dilution.

CAUTION: Escaping fluid under pressure
can penetrate the skin causing serious
injury. Avoid hazards by relieving pressure
before disconnec ing hydraulic or other
lines. Tighten all connections before
applying pressure. Search for leaks with a
piece of cardboard. Protect hands and body
from high pressure fluids.

DO NOT mix one brand of SCA with a
different brand.
Recharge the system per instructions printed on
label of the Coolant Conditioner.

Any time the fuel system has been opened up
for service (lines disconnected or filters
removed), it will be necessary to bleed air from
the system.

IMPORTANT: Always maintain coolant at
correct level and concentration. DO NOT
operate engine without coolant even for a
few minutes.

The fuel system may be bled at one of several
locations. Choose the best location for your
engine/machine application.

If frequent coolant makeup is required, the
glycol concentration should be checked to
ensure that the desired freeze point is
maintained. Follow manufacturer’s
instructions provided with Coolant/Battery
Tester.

1. Loosen the air bleed vent screw two full turns
by hand on fuel filter base.
2. Operate fuel supply pump primer lever (B) or
primer button on fuel filter base (if equipped).

Add the manufacturer’s recommended
concentration of supplemental coolant additive.
DO NOT add more than the recommended
amount.

3. Tighten bleed plug securely, continue
operating primer until pumping action is not
felt.
4. Start engine and check for leaks.

The use of non–recommended supplemental
coolant additives may result in additive drop–out
and gelation of the coolant.

If engine will not start, it may be necessary to
bleed air from fuel system at fuel injection pump
or injection nozzles as explained next.

If other coolants are used, consult the coolant
supplier and follow the manufacturer’s
recommendation for use of supplemental
coolant additives.

At Fuel Injection Pump
1. Loosen fuel return line at fuel injection pump.

Replacing Fan and Alternator Belts

2. Operate fuel supply pump primer lever or
primer button on fuel filter base (if equipped).

Refer to CHECKING BELT TENSIONER
SPRING TENSION AND BELT WEAR in
Lubrication and Maintenance/500 Hour/12
Month Section for additional information on the
belt tensioner.

3. As soon as fuel flow is free from air bubbles,
tighten fuel return line to specifications.
Primer lever is spring–loaded and will return
to normal position.

1. Inspect belts for cracks, fraying, or stretched
out areas. Replace if necessary.

Specification

At Fuel Injection Nozzles

A reliable program for troubleshooting engine
problems should include the following basic
diagnostic thought process:

IMPORTANT: Always use a backup wrench
when loosening or tightening fuel lines at
nozzles and/or injection pump to avoid
damage.

Know the engine and all related systems.
Study the problem thoroughly.

1. Using two open–end wrenches, loosen two
fuel line connections at injection nozzles.

Relate the symptoms to your knowledge of
engine and systems.

2. Crank engine over with starter motor for 15
seconds (but do not start engine) until fuel
free from bubbles flows out of loosened
connection. Retighten connection to
specifications.

Diagnose the problem starting with the
easiest things first.
Double–check before beginning the
disassembly.
Determine cause and make a thorough
repair.

Specification
Fuel Injection Nozzle Delivery
Lines—Torque 27 N•m (20 lb–ft)

After making repairs, operate the engine
under normal conditions to verify that the
problem and cause was corrected.

3. Repeat procedure for remaining injection
nozzles (if necessary) until all air has been
removed from fuel system.

NOTE: The engines covered in this manual
have electronic control systems which send
diagnostic trouble codes to signal problems.

If engine still will not start, see your authorized
servicing dealer or engine distributor.

Precautions For Welding On Engines
Equipped With Electronic Engine Control
Unit (ECU)

Do Not Modify Fuel System
IMPORTANT: Modification or alteration of
the injection pump, the injection pump
timing, or the fuel injectors in ways not
recommended by the manufacturer will
terminate the warranty obligation to the
purchaser.

IMPORTANT: ALWAYS disconnect Electronic
Control Unit (ECU) connectors and engine
control system–to–machine ground before
welding on engine or machine. High
currents or electro–static discharge in
electronic components from welding may
cause permanent damage.

In addition, tampering with fuel system
which alters emission–related equipment on
engines may result in fines or other
penalties, per EPA regulations or other local
emission laws.

1. Remove the ground connection for the
engine control system–to–machine frame.
2. Disconnect the connectors from the ECU.
3. Connect the welder ground close to the
welding point and be sure ECU or other
electronic components are not in the ground
path.

Do not attempt to service injection pump or
fuel injectors yourself. Special training and
special tools are required. (See your
authorized servicing dealer).

3. Engines can be stored inside, warehoused,
for up to six (6) months with no long term
preparation.

Intermittent Fault Diagnostics (With
Electronic Controls)
Intermittent faults are problems that periodically
“go away”. A problem such as a terminal that
intermittently doesn’t make contact can cause
an intermittent fault. Other intermittent may be
set only under certain operating conditions such
as heavy load, extended idle, etc. When
diagnosing intermittent faults, take special note
of the condition of wiring and connectors, since
a high percentage of intermittent problems
originate here. Check for loose, dirty or
disconnected connectors. Inspect the wiring
routing, looking for possible shorts caused by
contact with external parts (for example, rubbing
against sharp sheet metal edges). Inspect the
connector vicinity, looking for wires that have
pulled out of connectors, poorly positioned
terminals, damaged connectors and corroded or
damaged splices and terminals. Look for broken
wires, damaged splices, and wire–to–wire
shorts. Use good judgement if component
replacement is thought to be required.

Engines expected to be stored more than six (6)
months, long term storage preparation MUST
BE taken.
Preparing Engine for Long Term Storage
The following storage preparations are good for
long term engine storage up to one year. After
that, the engine should be started, warmed up,
and retreated for an extended storage period.
IMPORTANT: Any time your engine will not
be used for over six (6) months, the
following recommendations for storing it
and removing it from storage will help to
minimize corrosion and deterioration.
1. Change engine oil and replace filter. Used oil
will not give adequate protection.
2. Service air cleaner.
3. Draining and flushing of cooling system is not
necessary if engine is to be stored only for
several months. However, for extended
storage periods of a year or longer, it is
recommended that the cooling system be
drained, flushed, and refilled. Refill with
appropriate coolant.

NOTE: The engine control unit (ECU) is the
component LEAST likely to fail.
Suggestions for diagnosing intermittent
faults:
If the problem is intermittent, try to reproduce
the operating conditions that were present
when the diagnostic trouble code (DTC) set.

4. Crank the engine several revolutions with
starter (do not allow the engine to start).

Observing these values can help determine
the operating conditions when the fault
occurred.

5. Remove fan/alternator poly–vee belt, if
desired.
6. Remove and clean batteries. Store them in a
cool, dry place and keep them fully charged.

If a faulty connection or wire is suspected to
be the cause of the intermittent problem:
clear DTCs, then check the connection or
wire by wiggling it while watching the
diagnostic gauge to see if the fault resets.

7. Disengage the clutch for any driveline.
8. Clean the exterior of the engine with salt–free
water and touchup any scratched or chipped
painted surfaces with a good quality paint.

Possible causes of intermittent faults:

9. Coat all exposed (machined) metal surfaces
with grease or corrosion inhibitor if not
feasible to paint.

Faulty connection between sensor and
actuator harness.
Faulty contact between terminals in
connector.

10. Seal all openings on engine with plastic
bags and tape.

Faulty terminal/wire connection.

11. Store the engine in a dry protected place. If
engine must be stored outside, cover it with a
waterproof canvas or other suitable
protective material and use a strong
waterproof tape.

Electromagnetic interference (EMI) from an
improperly installed 2–way radio, etc., can
cause faulty signals to be sent to the ECU.
Storage
Engine Storage Guidelines
1. Engines can be stored outside for up to three
(3) months with no long term preparation IF
COVERED BY WATERPROOF COVERING.
2. Engines can be stored in a standard
overseas shipping container for up to three
(3) months with no long term preparation.

after operation of the auto blowdown valve.

ROUTINE MAINTENANCE

This pressure must be relieved by carefully:

This section refers to the various components which require
periodic maintenance and replacement.

(a) Disconnecting any downstream equipment.
(b) Opening the discharge valve to atmosphere.

The SERVICE/MAINTENANCE CHART indicates the
various components’ descriptions and the intervals when
maintenance has to take place. Oil capacities, etc., can be
found in the GENERAL INFORMATION section of this manual.

(Use hearing protection if necessary).

. the machine cannot be started accidently or otherwise, by
posting warning signs and/or fitting appropriate anti–start
devices.

For any specification or specific requirement on service or
preventative maintenance for the engine, refer to the Engine
Manufacturer’s Manual.

. all residual electrical power sources (mains and battery) are
isolated.

Compressed air can be dangerous if incorrectly handled.
Before doing any work on the unit, ensure that all pressure is
vented from the system and that the machine cannot be started
accidentally.
7/120 (P425AWIR), 9/110 (XP375AWIR), 10/105 (HP375AWIR), 14/85 (VHP300AWIR),
7/170 (P600WIR), 10/125 (HP450WIR), 14/115 (VHP400WIR)

Prior to opening or removing panels or covers to work
inside a machine, ensure that:–

. anyone entering the machine is aware of the reduced level
of protection and the additional hazards, including hot surfaces
and intermittently moving parts.

SCAVENGE LINE
The scavenge line runs from the combined orifice/drop tube
in the separator tank, to the orifice fitting located in the airend.

. the machine cannot be started accidently or otherwise, by
posting warning signs and/or fitting appropriate anti–start
devices.

Examine the orifice, check valve and hoses at every service
or in the event of oil carryover into the discharge air.
It is good preventative maintenance to check that the
scavenge line and tube are clear of any obstruction each time
the compressor lubricant is changed as any blockage will result
in oil carryover into the discharge air.

Prior to attempting any maintenance work on a running
machine, ensure that:–
. the work carried out is limited to only those tasks which
require the machine to run.

COMPRESSOR OIL FILTER
Refer to the MAINTENANCE CHART in this section for the
recommended servicing intervals.

. the work carried out with safety protection devices disabled
or removed is limited to only those tasks which require the
machine to be running with safety protection devices disabled
or removed.

Removal

. all hazards present are known (e.g. pressurised
components, electrically live components, removed panels,
covers and guards, extreme temperatures, inflow and outflow of
air, intermittently moving parts, safety valve discharge etc.).
.

appropriate personal protective equipment is worn.

loose clothing, jewellery, long hair etc. is made safe.

WARNING: Do not remove the filter(s) without first making
sure that the machine is stopped and the system has been
completely relieved of all air pressure. (Refer to STOPPING
THE UNIT in the OPERATING INSTRUCTIONS section of this
manual).

Clean the exterior of the filter housing and remove the
spin–on element by turning it in a counter–clockwise direction.

Progress are posted in a position that can be clearly seen.

Inspection
Examine the filter element.

Upon completion of maintenance tasks and prior to
returning the machine into service, ensure that:–
.

the machine is suitably tested.

all guards and safety protection devices are refitted.

all panels are replaced, canopy and doors closed.

CAUTION: If there is any indication of the formation of
varnishes, shellacs or lacquers on the filter element, it is a
warning that the compressor lubricating and cooling oil has
deteriorated and that it should be changed immediately. Refer
to LUBRICATION later in this section.

. hazardous materials are effectively contained and disposed
of.

Reassembly
Clean the filter gasket contact area and install the new
element by screwing in a clockwise direction until the gasket
makes contact with the filter housing. Tighten a further 1/2 to 3/4
of a revolution.

PROTECTIVE SHUTDOWN SYSTEM
Refer to the Wedge diagnostic display codes table for a
listing of shutdown conditions.

CAUTION: Start the machine (refer to PRIOR TO STARTING
and STARTING THE UNIT in the OPERATING

Disconnect all hoses and tubes from the separator tank
cover plate. Remove the drop–tube from the separator tank
cover plate and then remove the cover plate. Remove the
separator element.

AIR FILTER ELEMENTS
The air filter should be inspected regularly (refer to the
SERVICE/MAINTENANCE CHART) and the element replaced
when the restriction indicator shows red or every 6 Months (500
hours), whichever comes first. The dust collector box(es)
should be cleaned daily (more frequently in dusty operating
conditions) and not allowed to become more than half full.

Inspection
Examine the filter element. Examine all hoses and tubes,
and replace if necessary.

Removal
Reassembly
CAUTION: Never remove and replace element(s) when the
machine is running.

Thoroughly clean the orifice/drop tube and filter gasket
contact area before reassembly. Install the new element.

Clean the exterior of the filter housing and remove the filter
element by releasing the nut.

WARNING
Do not remove the staple from the anti–static gasket on
the separator element since it serves to ground any
possible static build–up. Do not use gasket sealant since
this will affect electrical conductance.

Inspection
Check for cracks, holes or any other damage to the element
by holding it up to a light source, or by passing a lamp inside.
Check the seal at the end of the element and replace if any
sign of damage is evident.

Reposition the cover plate, taking care not to damage the
gasket, and replace the cover plate screws tightening in a
criss–cross pattern to the recommended torque (refer to the
TORQUE SETTING TABLE later in this section).

Reassembly
Assemble the new element into the filter housing ensuring
that the seal seats properly.

Engage the adaptor in the cover plate with the drop–tube
integral with the filter, reconnect all hoses and tubes to the
separator tank cover plate.

Reset the restriction indicator by depressing the rubber
diaphragm.

Replace the compressor oil (refer to LUBRICATION later in
this section).

Assemble the dust collector box parts, ensuring that they are
correctly positioned.
CAUTION: Start the machine (refer to PRIOR TO STARTING
and STARTING THE UNIT in the OPERATING
INSTRUCTIONS section of this manual) and check for leakage
before the machine is put back into service.

Before restarting the machine, check that all clamps are
tight.

VENTILATION
Always check that the air inlets and outlets are clear of debris
etc.

COMPRESSOR OIL COOLER AND ENGINE RADIATOR
When grease, oil and dirt accumulate on the exterior surfaces
of the oil cooler and radiator, the efficiency is impaired. It is
recommended that each month the oil cooler and radiator be
cleaned by directing a jet of compressed air, (carrying if possible
a non–flammable cleaning solvent) over the exterior core of the
cooler/radiator. This should remove any accumulation of oil,
grease and dirt from the exterior core of the cooler so that the
entire cooling area can radiate the heat of the lubricating and
cooling oil/water into the air stream.

CAUTION: NEVER clean by blowing air inwards.

COOLING FAN DRIVE
Periodically check that the fan mounting bolts in the fan hub
have not loosened. If, for any reason, it becomes necessary to
remove the fan or re–tighten the fan mounting bolts, apply a
good grade of commercially available thread locking compound
to the bolt threads and tighten to the torque value shown in the
TORQUE SETTING TABLE later in this section.

WARNING: Hot engine coolant and steam can cause injury.
When adding coolant or antifreeze solution to the engine
radiator, stop the engine at least one minute prior to
releasing the radiator filler cap. Using a cloth to protect the
hand, slowly release the filler cap, absorbing any released
fluid with the cloth. Do not remove the filler cap until all
excess fluid is released and the engine cooling system fully
depressurised.

The fan belt(s) should be checked regularly for wear and
correct tensioning.
FUEL SYSTEM
The fuel tank should be filled daily or every eight hours. To
minimise condensation in the fuel tank(s), it is advisable to top
up after the machine is shut down or at the end of each working
day. At six month intervals drain any sediment or condensate
that may have accumulated in the tank(s).

WARNING: Follow the instructions provided by the
antifreeze supplier when adding or draining the antifreeze
solution. It is advisable to wear personal protective
equipment to prevent skin and eye contact with the
antifreeze solution.

adjust if necessary (Variable height only)

Replace the drain plug(s) ensuring that each one is secure.

Check the compression spring [9] for slight pre–tensioning.
LUBRICATION

NOTE: If the oil is drained immediately after the machine has
been running, then most of the sediment will be in suspension
and will therefore drain more readily.

The engine is initially supplied with engine oil sufficient for a
nominal period of operation (for more information, consult the
Engine section of this manual).

CAUTION: Some oil mixtures are incompatible and result in the
formation of varnishes, shellacs or lacquers which may be
insoluble.

CAUTION: Always check the oil levels before a new machine
is put into service.

NOTE: Always specify INGERSOLL–RAND Pro–TecTM oil for
use at all ambient temperatures above –23C.
If, for any reason, the unit has been drained, it must be
re–filled with new oil before it is put into operation.

STARTING AND USE
Select higher pressure setting with valve handle (handle to
right) and start machine normally.
If lower pressure is required then turn handle to up position.

SERVICE AIR

Toggle between high and low pressure as required.

OPTIONS – IQ SYSTEM

SAFETY
TO AFTERCOOLER

CAUTION: The compressor regulation system is adjusted to
maintain regulated pressure at the separator tank. DO NOT
adjust regulation to provide full regulation pressure at the
service valve when the IQ System is enabled. This will result
inC operation at excessive horsepower levels, causing
overheating, reduced engine life, and reduced airend life.

FROM FILTERS

Standard
Operation

SERVICE AIR

CAUTION: Excessively restricted filter elements may cause an
increase in the amount of aerosol water and oil carryover, which
could result in damage to downstream equipment. Normal
service intervals should not be exceeded.
CAUTION: Blockage of the condensate will result in flooding of
the vessels. If flooding occurs, excessive condensate may
enter the air stream and could result in damage to downstream
equipment.
CAUTION: Do not remove u–bolts from both filters at the same
time. Removing both u–bolts will place excessive stress on the
aftercooler.

OPTIONS
MAINTENANCE
Daily maintenance:
Verify, during full–load (maximum compressed air delivery) that
the IQ system filter restriction indicators do not show excessive
restriction.
Restriction indicators for primary and secondary filters are
located on the filter heads. If so equipped, an automatic
restriction indicator is located behind the filter mounting bracket
and will shut down the compressor if restriction exceeds
recommended values.
Weekly Maintenance:
Verify that the piping from the water separator and filters to
the exhaust system is not clogged.
Yearly Maintenance:
The normal maintenance interval on the primary and secondary
IQ System filters is one year, or earlier if pressure drop becomes
excessive.
Restriction indicators for the filters are mounted on the filter
heads. If so equipped, an automatic restriction indicator located
behind the filters will shut down the compressor if restriction
exceeds recommended values.
Filter replacement.
Remove all wires and hoses connected to drains on bottom
of each filter housing. Inspect fittings and hoses for any
blockage. Clean if necessary.
Using a chain wrench or similar tool, loosen the housing. The
housing should be removed by hand after loosening, taking care
to prevent the housing from falling to the floor panel.
Lower the housing to floor panel. Remove and replace the
filter element, being careful not to damage outer wrap.
Put a small amount of petroleum jelly or other non–synthetic
grease on the element o–ring to aid installation into the filter
head.
Replace housing making sure not to overtighten.
Repeat the above procedure on the remaining filter element.
Rec onnect all wires and hoses to drains on bottom of each
filter housing.

PARTS ORDERING
A series of illustrations show each part distinctly
and in location relative to the other parts in the
assembly. The part number, the description of the
part and the quantity of parts required are shown
on each illustration or on adjacent page. The
quantities specified are the number of parts used
per one assembly and are not necessarily the total
number of parts used in the machine. Where no
quantity is specified the quantity is assumed to be
one.

GENERAL
This publication, which contains an illustrated
parts breakdown, has been prepared as an aid in
locating those parts which may be required in the
maintenance of the unit. All of the compressor
parts, listed in the parts breakdown, are
manufactured with the same precision as the
original equipment. For the greatest protection
always insist on genuine Ingersoll–Rand
Company parts for your compressor.

Each description of a part is based upon the “noun
first” method, i.e., the identifying noun or item
name is always the first part of the description.
The noun name is generally followed by a single
descriptive modifier. The descriptive modifier
may be followed by words or abbreviations such
as upper, lower, inner, outer, front, rear, RH, LH,
etc. when they are essential.

NOTICE
Ingersoll–Rand Company can bear no
responsibility for injury or damages resulting
directly from the use of non–approved repair
parts.
Ingersoll–Rand Company service facilities and
parts are available worldwide.
There are
Ingersoll–
Rand
Company
Construction
Equipment Group Sales Offices and authorized
distributors located in the principal cities of the
United States. In Canada our customers are
serviced by the Canadian Ingersoll–Rand
Company,
Limited.
There are also
Ingersoll–Rand
International
autonomous
companies and authorized distributors located in
the principal cities throughout the free world.

In referring to the rear, the front or to either side
of the unit, always consider the drawbar end of
the unit as the front. Standing at the rear of the
unit facing the drawbar (front) will determine the
right and left sides.

FASTENERS
Both SAE/inch, ISO/metric hardware have been
used in the design and assembly of these units.
In the disassembly and reassembly of parts,
extreme care must be taken to avoid damaging
threads by the use of wrong fasteners. In order to
clarify the proper usage and for exact
replacement parts, all standard fasteners have
been identified by part number, size and
description. This will enable a customer to obtain
fasteners locally rather than ordering from the
factory. These parts are identified in tables that
will be found at the rear of the parts illustrations.
Any fastener that has not been identified by both
