Unloader Blow-Off Pressure: All models are continu-

ously running outfits controlled by tank pressure when

the maximum tank pressure is obtained, the unloader

valve will blow-off. This will cause the compressor to

exhaust the air to the atmosphere and not the tank.

This decreases the load on the engine and allows it to

run at a near no-load condition.

Unloader Reset Pressure: When the tank pressure

drops to apredetermined point, the unloader valve

closes. The tank pressure will now increase until it

reaches the unloader blow-off pressure.

020396 Rev 02/16/00

You have purchased an air compressor unit consisting of

a 2 cylinder, single-stage air compressor pump and air

tank. Included with portable compressors are wheels,

gauges, and handle.

Your air compressor can be used for operating paint spray

guns, air tools, caulking guns, grease guns, air brushes,

sandblaster, or inflating tires and plastic toys, spraying

weed killers, insecticides, etc.

An air pressure regulator is usually required for most of

these applications. Regulators can be purchased from

most Sears stores or through the Sears Power Tool

Catalog.

Separate air transformers which combine the functions or

air regulation and/or moisture and dirt removal should be

used where applicable.

Figure 1

Air Compressor Pump: To compress air, the pistons

move up and down in the cylinders. On the downstroke,

air is drawn in through the air intake filter and then through

the air intake valves. The exhaust valve remains closed.

On the upstroke of the piston, air is compressed. The

intake valves close and compressed air is forced out

through the exhaust valve, th rough the outlet tube, through

the check valve and into the air tank. Working air is not

available until the compressor has raised airtank pressure

above that required at the air outlet.

Throttle Control: Athrottle control has been incorporated

as an extra feature. When maximum tank pressure is

reached and the unloader valve unloads air, it also

activates a throttle control on the engine. This gas saving

featu re holds the engine at a factory-set idling speed until

air pressure in the air tank drops to reset pressure; it then

reactivates the throttle control and accelerates the engine

to full throttle.

Unloader Valve: All models are continuously running

outfits controlled by tank pressure. When the maximum

tank pressure is obtained, the unloader valve will exhaust

the compressed air to the atmosphere (blow-off). When

the pressure drops to a predetermined point, the unloader

valve closes and causes the tank pressure to increase.

Safety Valve: If the pressure switch does not shut off the

air compressor at or near its cut-out pressure setting, the

safety valve will protect against high pressure by "pop-

ping out" at its factory set pressure (slightly higherthan the

pressure switch cut-out setting).

Check Valve: When the air compressor is operating, the

check valve is "open," allowing compressed air to enter

the air tank. When the air compressor reaches "cut-out"

pressure, the check valve "closes," allowing air pressure

to remain inside the air tank. If the air is not unloaded, the

motor will try to start, but will be unable to. The check valve

allows the motor to restart freely.

Shut Off Valve: Turn the knob counterclockwise to open

the valve and clockwise to close.

Compressors are shipped without oil. Do not

attempt to operate this air compressor without

first adding oil to the compressor pump

crankcase and engine crankcase.

Place unit on a level surface. Remove compressor oil fill

plug and slowly add a special compressor oil such as

Sears compressor oil or SAE-20-20W SF motor oil until

it is even with the top of the oil fill hole. (It must not be

allowed to be lower than 3/8" - 6 th reads down - fro m the

top.) When filling the crankcase, the oil flows very

slowly. If the oil is added too quickly, it will overflow and

appear to be full. (Crankcase oil capacity is 16 fluid

ounces.) Under winter-type conditions use SAE 10W oil.

(Multi-viscosity oil - 10W30 - will leave carbon deposits

on critical components reducing performance and com-

pressor life.) Replace oil fill plug.

Remove engine oil fill plug and slowly add oil to the point

of overflowing. Use a high quality oil classified "FOR

SERVICE SC, SD, SE or MS,". See Briggs and Stratton

"OPERATING AND MAINTENANCE INSTRUCTIONS" for

recommended SAE viscosity grades. (Engine crankcase

capacity is 20 fluid ounces.)

For your convenience, purchase a W' NPT nipple 2V2"

long, and a 1/4" NPT x 1/4"NPT coupling (pipe collar) to

allow ease in draining oil. Remove oil drain plug on the

gas tank side of the engine and install the nipple. Thread

the ooupting on the end of the nipple and screw the drain

plug in the coupling. See figure 3.

A warm engine requires less choking than a cold engine.

Unit is top heavy. Make sure the compres-

sor is stable and will not tip before pulling

the starting cord,

Place your left hand on the air compressor handle,

and your right hand on the starter handle, and pull

cord out quickly to overcome engine compression

and prevent "kickback". If engin e does not start,

push the choke about three-quarters of the way in or

choke level three quarters to the left and pull starter

handle again. When engine starts, push choke in or

choke lever to the left gradually.

Serious damage may result in the following

break-in instructions are not followed.

Pump Break-in: Open the outlet valve to prevent tank

pressure build-up. Run the air compressor for 30

minutes to seat the rings and lubricate all internal

surfaces. This operation must be completed only

once when first putting the unit in service.

After completing the above, and when ready to begin

using the compressor, move the unloader valve

toggle lever to a horizontal position. Close the outlet

valve to build tank pressure.

Engine Break-in: After the first 5 hours of normal

running, change the engine oil. Then after every 25

hours the engine oil should be changed.

D20396 Rev 0 2/16/00

1. Before attaching an air hose or accessory, make

sure the engine is off. Close the outlet valve or

pressure regulator. (If an optional air pressure

regulator is not used, do not use accessories rated

at less than 110 psig.)

2. Attach hose and accessory.

TOO MUCH AIR PRESSURE CAUSES A

HAZARDOUS RISK OF BURSTING. CARE-

FULLY FOLLOW STEPS 3 THROUGH 10

EACH TIME THE COMPRESSOR IS USED.

3. Check the manufacturer's maximum pressure

rating for air tools and accessories. The compressor

outlet pressure must never exceed the maximum

pressure rating.

4. Start the engine and allow tank pressure to build.

Your outfit is ready for use.

Compressed air from the outfit may contain

water condensation and oil mist. Do not

spray unfiltered air at an item that could

be damaged. Some air operated tools or

devices may require filtered air. Read the

instructions for the air tool or device.

When you are finished:

5. Turn offengine.

6. Shut-off outlet valve or air pressure regulator.

7. Remove air tool or accessory.

8. Open outlet valve or regulator and allow air to slowly

bleed from the tank. Closethe outlet vavleor regulator

when the tank pressure is approximately 20 psig.

10,

WATER WILL CONDENSE IN TANK. IF NOT

DRAINED, WATER WILL CORRODE AND

WEAKEN THE AIR TANK CAUSING A RISK

OF TANK RUPTURE. SEE STEP 9.

With tank pressure at approximately 20 PSI, open

the drain cock and allow moisture to drain. Turn the

drain T-handle counterclockwise to open.

NOTE

If drain cock is clogged, release all air pres-

sure. The drain cock can then be removed,

cleaned, and then reinstalled.

After the water has been drained, close the drain

cock. The compressor outfit can now be stored.

DURING MAINTENANCE, YOU COULD BE EXPOSED TO COMPRESSED AIR OR MOVING PARTS. PER-

SONAL INJURIES CAN OCCUR. BEFORE DOING ANY MAINTENANCE OR REPAIR, DISCONNECT THE

SPARK PLUG WIRE TO PREVENT ACCIDENTAL STARTING, AND RELIEVE AIR TANK PRESSURE. NEVER

OPERATE THE COMPRESSOR WITH THE BELT GUARD REMOVED.

Air Compressor

Aclean air compressor and engine run cooler and

provide longer service. Clean or blow off fins and any

other parts of the air compressor and enginethat collect

dust or dirt, Do not place rags, containers or other

material on or against the compressor. Ventilation is

necessary to maintain proper air compressor operating

temperature.

Compressor Pump Air Intake Filter --

Inspection and Replacement

A dirty air filter will not allow the compressor to operate

at full capacity. Before you use the compressor, check

the air filter to be sure it is clean.

Compressor Oil -- Checking and Changing

Check oil level in the crankcase daily. The oil level

should be even with the top of the fill hole and must not

be allowed to be lower than 3/8" from the top (6threads)

at any time. It is recommended that the oil be changed

after every 100 hours of operation. To drain the oil,

remove the oil drain plug and collect the oil in a suitable

container. Be sure to replace the plug securely before

adding new oil. Use a special compressor oil such as

Sears compressor oil or SAE 20-20W SF motor oil.

(Crankcase oil capacity is 16 fluid ounces.) Under

extreme winter conditions use 10 weight oil. Multi-

viscosity oil (10W30) will leave carbon deposits on

critical components reducing performance and com-

pressor life.

If it is dirty, replace with a new filter. The filter may be

removed by using a pair of needle nose pliers or a

screwdriver. Pull or pry out the old filter and push in a

new one.

Check Valve -- Inspection and Replacement

Remove the check valve for inspection or replacement

if air is leaking constantly back through the check valve.

Use the following procedure to inspect, clean or replace

the check valve.

11 - ENG 020396 Rev 0 2/16/00

Release air pressure from the air tank.

Loosen the top and bottom tube nuts and remove the

outlet tube (Nos. 4 and 6).

Unscrew the check valve (turn counterclockwise)

using a socket wrench (No. 3).

Check that the valve disc moves freely inside the

check valve and that the spring holds the disc in the

upper, closed position. The check valve may be

cleaned with a solvent.

Apply sealant to the check valve threads. Reinstall

the check valve (turn clockwise). The disc should still

move freely -- do not overtighten.

Replace the outlet tube and tighten top and bottom

nuts (Nos. 6 and 4).

Safety Valve -- Inspection and Replace-

ment

IF THE SAFETY VALVE DOES NOT WORK

PROPERLY OVER-PRESSURIZATION MAY

OCCUR, CAUSING AIR TANK RUPTURE OR

EXPLOSION. OCCASIONALLY PULL THE

RING ON THE SAFETY VALVE TO MAKE

SURE THAT THE SAFETY VALVE OPERATES

FREELY. IF THE VALVE IS STUCK OR DOES

NOT OPERATE SMOOTHLY, IT MUST BE

REPLACED WITH THE SAME TYPE OF VALVE

HAVING AN IDENTICAL PRESSURE RATING.

Engine -- Oil Change and Air Cleaner

See Briggs & Stratton "Operating and Maintenance In-

structions" for information regarding engine oil changes

and air cleaner service.

Engine -- Adjustments

Read the Briggs & Stratton "Operating and Maintenance

Instructions" that were provided with your compressor.

The gasoline engine was adjusted and set at the factory

to ensure correct operation. However, variationsin gaso-

line quality and octane, humidity, altitude or load may

adversely affect engine performance. As a result, minor

adjustments of fuel mixture or speed controls may be

necessary.

To adjust the fuel mixture, turn the needle valve clock-

wise until it closes• See figure 6.

Figure 6

NEEDLEVALVE

NOTE

The air cleaner must be in place when any

carburetor adjustments are made.

Turn the needle valve clockwise (in) until the

engine misses, noting the valve position

(lean mixture). Turn the needle valve coun-

terclockwise (out) until engine runs roughly,

again noting valve position (rich mixture).

Now, turn the needle valve clockwise (in) to

the point midway between lean and rich

where the engine runs smoothly.

If the compressor stalls frequently during

acceleration from idle speed, richen mixture

sightly (by turning the needle valve out

slowly). If this adjustment does not elimi-

nate the stalls, adjust the idle speed to a

slightly higher level by loosening the two jam

nuts on the throttle control cylinder, read-

justing its position and retightening the

nuts. See figure 7. Proper idle speed is

between 2400 and 2600 RPM.

If the throttle mechanism fails to operate

smoothly, preventing the engine from returing

to full throttle speed when tank pressure

falls below 90 psig, it may be necessary to

lubricate it with a light lubricating oil. See

figure 7.

LUBRICATE

rER

SLOWER

The needle valve point may be damaged if

turned in too far.

Turn the needle valve 1_/2revolutions counterclockwise

to establish a point of reference. Start the engine and

allow it to warm up.

Figure 7

Proper no-load engine speed may be checked and

adjusted using the following procedures:

1. Remove the belt guard and belt. Start engine

12 - ENG

D20396 Hey 0 2/16/00

NOTE

This is the only time you should operate

your compressor with the belt guard

removed. Use caution when checking

engine speed.

"vvRIiW_]_IR[_

High engine speeds greatly increase

vibration loads on air tank. This could

weaken the tank and cause it to rupture or

explode. Damage to the engine can also

occur. Engine RPM must be set per specifi-

cation.

2. Measure engine speed with belt removed using a

tachometer. Speed should be as follows:

Compressor Model No.

919.157251

No-Load (Max)

Speed (± 100 RPM)

3700 RPM

If speed is correct go to Step 5.

Four bolts fasten the engine to tank base. Position

yourself on the starter rope side of engine and locate

that engine mounting bolt nearest you on the left. In

this area, there is one vertical spring. Locate the

vertical spring situated directly above the mounting

bolt just described.

Locate lever to which the lower end of the vertical

spring is attached. See figu re 8. Using needle nosed

pliers, bend the lever slightly downward to increase

engine speed or bend slightly upward to decrease

engine speed.

SERIOUS INJURY OR DAMAGE MAY OCCUR

IF PARTS OF THE BODY OR LOOSE ITEMS

GET CAUGHT IN MOVING PARTS. NEVER

OPERATE THE OUTFIT WITH THE BELT

GUARD REMOVED. THE BELT GUARD

SHOULD BE REMOVED ONLY AFTER THE

SPARK PLUG WIRE HAS BEEN DISCON-

NECTED.

Belt Replacement

To replace belt:

1. Disconnect spark plug wire.

2. Remove belt guard.

3. Loosen four engine mounting screws, two saddle/

stiffener plate screws, handle set screw, and stiff

ener bar nut on engine and slide engine toward

compressor.

4. Remove belt and replace with new.

NOTE

The belt must be centered over the grooves

on the flywheel and engine pulley.

5. Push the engine back into regular position. Achieve

belt tension by inserting a large screwdriver into the

hole in the saddle which is located on the belt guard

side of the saddle below the engine and prying the

stiffener plate back. See figure 9. Proper tension is

approximately 1/4" belt deflection measured mid

way between the pulley and flywheel when a 3-

pound weight or equivalent finger pressure is

applied at this point. See figure 10.

are tightened securely+

7. Tighten remaining engine mounting screws, saddle/

stiffener plate screws, handle set screw and

stiffener bar nut.

8. Reinstall belt guard and screws.

NOTE

Once the engine pulley has been moved from

its factory set location, the grooves of the

flywheel and pulley must be aligned within

1/16" to prevent belt wear,

Pulley and Flywheel -- Alignment

The compressor flywheel and motor pulley must be inline

(inthe same plane) within 1/16" to assure belt retention

within sheave grooves. To check align ment, disconnect

spark plug wire and remove the beltguard. Place a

straightedge against the outside of the flywheel and

measure the distance from it to the nearest groove.

Alignment isachieved when the other end of the straight-

edge is within f/16" of the measured dimension at the

pulley grooves. Squareness is achieved when the pulley

grooves are an equal distance from the straightedge on

both sides of the motor shaft.

Before You Store The Air Compressor

1. Review the "Operating Procedures +'and

"Maintenance" sections onthe precedingpagesand

performmaintenance asnecessary. Drain the water

from the air tank.

2. Reviewthe Briggs&Stratton "Operating andMainte-

nance Instructions".

Remove the air tool or accessory.

Protect the air hose from damage (such as being

stepped on or run over). Wind it loosely around the
