WHAT TOOLS CAN BE POWERED
The PP 418 power pack is equipped with an adjustable fl ow
hydraulic pump which produces hydraulic power more
effi ciently than a more commonly used fi xed displacement
gear pump.
The PP 418 power pack is suited to power any hydraulic tool
with the following specifi cations;
Hydraulic valve: “Open Center”
Flow Requirement: 20, 30 or 40 l/min
(5, 8 or 10 gal/min)
Maximum Pressure: 140 bar (2000 psi) or higher
The PP 418 includes a 7.5 m (25 ft) long hose set in a 1/2”
(12.7 mm) inside diameter. You can attach ONE additional
1/2” hose of up to 10 m (33 ft) (total of 18-20 meters / 60-65 ft).
If you require a longer hose for your application we
recommend the following:
Maximum hose extension - up to 40 m (130 feet) total distance:
- Use the 7.5 m (25 feet) of hose included with the power pack.
- Make two 16 m (53 ft) extension hoses in a minimum of 5/8”
(16 mm) hose diameter.
One 32 m (100 ft) length can also be used - however it is more
bulky to handle.
We strongly recommend using HTMA “Flat Face” compatible
quick couplers.
HYDRAULIC HOSES AND COUPLERS
Examples of Husqvarna hydraulic tools that can be used with
the PP 418 without any modifi cations:
Hand Saw K2500
Ring Saws K3500, K3600
Core Drill DM406H
Wall Saw WS325
Other popular tools are:
Hydraulic Chain Saw
Hydraulic Water Pump
Hydraulic Breaker
If you are unsure of the compatibility of any tool - please
consult the tool manufacturer or
Husqvarna Construction Products.
NOTICE:
The direction of fl ow through the system is always; male fi tting
into the female fi tting. This means that any extension hoses
should be made up the same way. If you have a male fi tting in
one end of a hose you should always have a female fi tting in
the opposite end. Never use two fi ttings of the same gender
on the same hose.
CAUTION
The hydraulic oil and therefore the hoses and
hydraulic couplers can get scalding hot during normal
operation.
A hydraulic coupler at a temperature of 50°C (120°F) will be
perceived as HOT to the touch. It is normal that the power
pack oil might become as hot as 60°C (145°F) if operated on
a very hot day with ambient temperatures exceeding 40°C
(104°F).
For reference - a car engine typically operates at 90°C (195°F)
CAUTION
The hydraulic hoses and fi ttings shall have a
minimum pressure rating of 140 bar (2000 psi) with a
safety factor of 4 to 1.

CAUTION
If a tool requires 20 lpm/5 gpm of fl ow - it SHALL NOT
be operated with a higher setting – such as 8 or 10
gal/min. This can cause severe damage to the tool or
even personal injury.
Always consult the manufacturer of a tool before
hooking it up to the power pack.

FUEL HANDLING
PROPER FUEL
Taking the following precautions will lessen the risk
of injury and property damage:
- Use extreme care in handling gasoline. It is
extremely fl ammable and the vapors are explosive.
- Extinguish all cigarettes, cigars, pipes, and other
sources of ignition.
- Use only approved gasoline containers.
- Never remove gas cap or add fuel with the engine
running. Allow engine to cool a minimum of 3
minutes before refueling.
- Never fuel the machine indoors.
- Never store the machine or fuel container where
there is an open fl ame, spark, or pilot light such as
on a water heater or other appliances.
- Never fi ll containers inside a vehicle or on a truck
or trailer bed with a plastic liner. Always place con-
tainers on the ground away from your vehicle when
fi lling.
- Remove the power pack from the truck or trailer
and refuel it on the ground. If this is not possible,
then refuel the equipment with a portable container,
rather than from a gasoline dispenser nozzle.
- Keep the nozzle in contact with the rim of the fuel
tank or container opening at all times until fueling is
complete. Do not use a nozzle lock-open device.
- If fuel is spilled on clothing, change clothing
immediately.
- Never overfi ll fuel tank. Always wipe off any spilled
fuel or oil. Replace fuel cap and tighten
The BRIGGS & STRATTON engine is certifi ed to operate on
unleaded gasoline with a pump octane rating (M+R) of 86 or
higher, or a research octane rating (R) of 91 or higher.
Refuel in a well-ventilated area with the engine stopped.
You may use regular unleaded gasoline containing no more
than 10% ethanol (E10). Do not use gasoline containing
methanol.
Use of fuels with an ethanol content of more than 10% (E10)
may cause starting and/or performance problems. It may also
damage metal, rubber, and plastic parts of the fuel system, as
well as posing a fi re hazard.
Do not use fuel that is older than 30 days. Old fuel can cause
running problems as well as fuel system damage.
The engine will not operate on gasoline
marketed as E-85 (85% ethanol)
OIL HANDLING
WARNING
Used oil is a hazardous waste product. Dispose
of used oil properly. Do not discard with household
waste. Check with your local authorities, service
center, or dealer for safe disposal/recycling facility.
NOTICE

Step 5
The power pack is delivered without the battery cables
installed to the battery. Please read;
SERVICING THE BATTERY on page 10.
The original equipment battery is maintenance free. Do not
attempt to open or remove caps or covers. Adding or checking
the level of electrolyte is not necessary.
WARNING
Lead-acid batteries generate explosive gases.
Keep sparks, fl ame and smoking materials away from
batteries. Always wear eye protection when around
batteries.
Step 4
Check the tire pressure. The wheels are tubeless. If the tire
pressure becomes too low the wheel will defl ate completely.
Infl ate to 2 bar (30 psi)
If the hydraulic hoses (7.5 m/25 ft) are empty they will require
approximately 1.8 liters (2 quarts) of additional oil to be added
to the oil tank after running the power pack for the fi rst time.
If an additional 30 m (100 ft) of 5/8” hose set is used they will
require approximately 12 liters (3.2 gal) to be added. The oil
level in the oil tank must be rechecked several times when
fi lling a new hose set.
Step 6
Fill the fuel tank with fresh clean gasoline. See warnings and
recommendations on page 8. Add only fuel in a quantity that
will be used within 30 days to assure fuel freshness. If the
power pack is stored with fuel in the tank for longer periods we
recommend to use a commercially available “Fuel Stabilizer”.

SERVICING THE BATTERY
Use the following procedure when removing, installing and
attaching the battery cables.
The battery is located in the support foot of the power pack.
To access the battery you will need another person helping
you.
Step 1
Remove the two M8 bolts using a 10 mm wrench. Keep the
two bolts nearby for Step 3
WARNING
- Connecting and disconnecting a battery can cause
sparks and short circuits. Do not short battery ter-
minals by allowing a wrench or any other object to
contact both terminals at the same time.
- A spark or fl ame can cause a lead acid battery to
explode.
- Before connecting a battery, remove metal
bracelets, wristwatch bands, rings, etc. Use gloves
and protective glasses or face shield when working
with a battery.
- Install and remove the battery cables ONLY in the
sequence described in this section.
Step 2
Have one person lift the power pack with the handle. With the
“battery box” no longer supporting the power pack it can be
pivoted downward. This will give you full access to the battery
and cables.
Step 3
Secure the battery box in the “open” position by inserting the
two M8 screws removed in Step 1 into the exposed holes in
the battery box (see illustration). Use one bolt on each side.
The battery supplied as original equipment is maintenance
free. Do not attempt to open or remove caps or covers.
Adding or checking the electrolyte level is not necessary.
Replace only with an equivalent maintenance free battery with
the following specifi cations;
Case size: U1

CONTROLS - OPERATION
Choke Lever
Ignition Switch
Flow Selector
Throttle Control
IGNITION SWITCH
STOP – Kills the engine – no power to any of the
electrical devices.
RUN – Run position for the engine. Please note that the hour
meter will collect time whether or not the engine is running. If
the key is left in the RUN position the battery will also loose
power more quickly.
START – Turns the engine starter motor.
THROTTLE CONTROL
The engine has a very accurate electronic throttle and
governing system. The engine speed is strictly controlled
electronically and you cannot make any simple mechanical
adjustments to the governing system. The electronic control
will accurately hold the speeds as indicated below.
The throttle control switch allows you to select one of two
different operating throttle control modes:
1. Automatic throttle control switch in the OFF position.
- During the starting procedure the engine will run at
2100 RPM for 5 seconds.
- After 5 seconds the engine speed will increase to
3100 RPM and hold that speed.
2. Automatic throttle control switch in the ON position.
- During the starting procedure the engine will run at 2100
RPM for 5 seconds.
- After 5 seconds the idle speed will drop to 1900 RPM.
- When the trigger on a tool is activated a pressure
sensor switch on the power pack will increase the
engine speed to 3100 RPM.
- When the tool is no longer used the engine speed will
drop back to 1900 RPM after 5 seconds.
cont..
There is a slight delay for the engine to go from idle speed to
full throttle operation. To help prevent this inconvenience, the
full throttle position is maintained for 5 seconds. This is
particularly helpful when a tool is operated intermittently
(Hydraulic Breaker for example) and full power is required
instantly.
If desired, full throttle operation can be maintained by moving
the Automatic throttle control switch to the OFF position.
The sensitivity of the automatic throttle control system can
be adjusted to compensate for conditions such as increased
back pressure from adding hose extensions, operation at lower
temperatures, oil viscosity differences, etc.
Please see “ADJUSTING THE AUTOMATIC THROTTLE” on
page 13.
FLOW SELECTOR
To adjust the oil fl ow PULL out on the fl ow selector knob and
move it to the left for the desired oil fl ow. Please consult the
operator’s manual for fl ow requirements of a specifi c tool.
Do not use a higher than recommend setting since that can
damage the tool.
After the work is fi nished ALWAYS return the fl ow selector to
“0” before stopping the engine.
Always start the engine with the fl ow selector in the “0”
position. This ensures that the electric starter can turn over
the engine.
This power pack is capable of producing up to 40 liter/ 10 gal
of oil fl ow per min. The factory pressure relief valve setting is
148bar (2150psi) “cracking” pressure.

STARTING CHECKLIST
BEFORE YOU OPERATE THE POWER PACK,
PLEASE REVIEW THE FOLLOWING CHECKLIST:
- Have you read and do you understand ALL instructions and
warnings in this manual?
- Is the battery properly charged and installed? (page 10)
- Are the tires properly infl ated? (page 9)
- Is the engine oil at the proper level? (page 9)
- Is the fuel tank fi lled with fresh, clean, regular unleaded
gasoline? (page 8)
- Has the hydraulic tank been fi lled to the proper level?
(pages 8 and 9)
- Are you familiar with the controls, their location and function?
Operate them before you start the engine.
- Have you attached the hydraulic hoses to the power pack?
Connect the other end of the hoses to a hydraulic tool or to
each other. (page 9)
NOTICE:
STARTING THE FIRST TIME
If the power pack was received without hydraulic oil in the tank
and hoses, the oil levels must be checked carefully before us-
ing it for the fi rst time.
A new empty hydraulic hose set will require approx. 1.8 liters
(2 quarts) of oil.
After starting the power pack and turning the fl ow selector to
the desired setting, the oil will fi ll the hydraulic hoses. Before
putting the machine to work the hydraulic oil tank level should
be checked.
Stop the engine and add hydraulic oil as needed.
WARNING
ASPHYXIATION HAZARD
Running an engine in a confi ned or badly ventilated
area can result in injury or death due to asphyxiation
or carbon monoxide poisoning.
STARTING PROCEDURE:
Before starting;
Always set the fl ow controller to “0” before starting.
Connect the hoses to the tool and to the power pack.
The AUTOMATIC THROTTLE switch can be turned to either
ON or OFF.
After starting;
Let the engine warm up for 1 to 2 minutes.
Turn the FLOW SELECTOR to the desired setting. This
makes the hydraulic oil fl ow from the pump through the hoses
to the tool.
In cold weather we recommend letting the power pack pump
the oil through the hoses and the tool until the temperature of
the oil has reached a minimum of 10°C (50°F) before using the
tool. This ensures the proper function of the automatic throttle.
See page 13 for a full explanation on how to adjust the sensi-
tivity of the AUTOMATIC THROTTLE function.
WARNING
Before each use, carefully inspect the power pack
for any damage to any of its parts and components.
Pay careful attention to any leakage of gasoline or
oil. Under no circumstance should the power pack
or any of its attachments be operated if you fi nd
damage or are suspicious that something appears to
be damaged.
13
ADJUSTING THE AUTOMATIC THROTTLE
GENERAL DESCRIPTION
The AUTOMATIC THROTTLE function is triggered by an
adjustable pressure switch located on the hydraulic manifold.
When the fl ow selector is set to (for example) 40 liters (10 gal),
that amount of oil will circulate through the hoses and through
the tool and back to the tank.
The circulation of the oil through the hoses creates a small
pressure (known as “back pressure”) at the pressure switch.
The back pressure in the system can vary for many reasons
such as; - Cold hydraulic oil
- The length of the hoses – a longer hose
creates more back pressure.
- The valve in the hydraulic tool can have a
high restriction.
In some applications the hydraulic system restriction may be
too low. This will cause the engine to remain at idle speed
even after the tool is engaged and full power is required.
When a trigger is activated at the tool, the oil pressure quickly
rises to in excess 50 bar (700 psi). This normally triggers the
AUTOMATIC THROTTLE control to increase the throttle to
“FULL”. It is desirable that the engine engages to full throttle
immediately when the tool is activated.
Throttle Control
Pressure Switch
Pressure
Relief Valve
ADJUSTMENT
On the PP 418 the threshold pressure at which the
throttle reacts can be adjusted to reach a desired function for a
specifi c tool and condition.
Step 1
Hook up the hoses and tool to be used.
Step 2
Turn the AUTOMATIC THROTTLE switch to the ON position.
Start the engine and let it idle for 1 minute. The engine will
now idle at 1900 RPM.
Step 3
Turn the FLOW SELECTOR to the proper setting for the tool.
Note: If the oil is cold the back pressure in the system can
trigger the full throttle function.
Step 4
Let the hydraulic oil warm up for one or two minutes. It is now
OK to start the work. The hydraulic oil will reach a stabilized
operational temperature in approximately 5 to 10 minutes.
Step 5
If the machine has been operated for 10 minutes and the
AUTOMATIC THROTTLE function is not working correctly
the pressure threshold value between the idle and full throttle
function can be adjusted.
NOTICE:
The Throttle Control Pressure Switch setting has NO impact
on the relief valve setting (= maximum system pressure). It is
strictly sensing the system pressure to signal the controller to
operate the engine at Idle or Full Throttle.
DO NOT adjust the pressure relief valve.
Scenario 1.
With the Automatic throttle switch in the ON position, the
engine will stay at FULL THROTTLE even when the hydraulic
oil is hot.
Adjustment Turn the Adjustment Screw -
Clockwise in 1/8 turn increments
until proper function is achieved.
Scenario 2.
The engine will remain at IDLE SPEED when the tool is
engaged. It might work OK when the oil is cold.
Adjustment Turn the Adjustment Screw -
Counter Clockwise in 1/8 turn increments
until proper function is achieved.
Use an 8 mm or 5/16” hex
key to adjust the throttle
threshold pressure

Engine Oil
Checking, Adding and Changing Oil
Always check the oil level before starting the engine.
Keep oil level at FULL. Do not overfi ll. Check level daily, or
after every eight (8) hours of use.
Note: Engine holds approximately 1.4 liters (1.5 quart) when
changing oil and oil fi lter.
Always place the Power Pack on a level surface when check-
ing and changing the oil
Changing the Oil and Filter
Change oil after the fi rst 5 to 8 hours of use.
Thereafter every 50 hours .
Follow the recommendations on page 8 as well as in the
BRIGGS & STRATTON Operator’s Manual.
ENGINE MAINTENANCE
1. With engine OFF but still warm, remove oil drain plug and
drain oil into appropriate receptacle and remove the oil fi lter.
2. Before installing new fi lter, lightly oil fi lter gasket
with fresh, clean oil.
3. Screw fi lter on by hand until gasket contacts oil
fi lter adapter. Tighten 1/2 to 3/4 turn more.
4. First add 1 liter (1 quart) of any of the specifi ed oil qualities.
5. Start and run engine for 30 seconds.
6. Stop engine. Re-check oil level – Top off as necessary
– typically 0.3 - 0.5 liter (12 - 16 oz).
Oil Pressure
- If the oil pressure drops below 0.1-0.2 kg/cm (1-4 psi), an oil
pressure switch will stop the engine.
- If oil level is below the ADD mark on dipstick, add oil to bring
level to FULL mark. Try to start the engine.
- If this does not correct the problem contact an authorized
BRIGGS & STRATTON service dealer.
OIL FILTER
Replace every 100 hours.
Change Oil Filter after every 100 hours
We strongly recommend to only use the BRIGGS &
STRATTON original replacement parts
OIL FILTER ACCESS
Remove the 6 screws as indicated below. This will enable full
access to the engine oil fi lter.
ENGINE OIL DRAIN
Replace oil every 50 hours.
NOTICE
AIR FILTER
Your engine will not run properly using a dirty air fi lter.
Inspect and service the air cleaner at each oil change - every
50 hours.
MUFFLER
Inspect and replace corroded muffl er and spark arrester (if
equipped) as it could create a fi re hazard and/or damage.
Also - inspect the spark arrester screen for carbon deposits. A
partially plugged screen will cause loss of power. It is recom-
mended to inspect the screen at each oil change.
IN-LINE FUEL FILTER
The fuel fi lter should be replaced once each season. If fuel
fi lter becomes clogged, obstructing fuel fl ow to carburetor, re-
placement is required. We recommend to replace the fuel fi lter
every 250 hours
ADDITIONAL ENGINE INFORMATION
Please see the BRIGGS & STRATTON Operator’s Manual for
additional information about servicing the engine.
The manual also has specifi c information about specifi cations,
tune-up parts, engine warranty, emission compliance, etc.
Used oil is a hazardous waste product. Dispose of
used oil properly. Do not discard with household
waste. Check with your local authorities, service
center, or dealer for safe disposal/recycling facility.
HYDRAULIC MAINTENANCE
SYSTEM MAINTENANCE
Daily
1. Check hydraulic oil level. Make sure that the oil level on
the sight glass is above the lower limit indicated. Add oil as
needed.
HYDRAULIC SYSTEM SPECIFICATIONS
Oil Tank volume: 10 liter (2.6 gal)
Oil Type: ISO 46 (see page 8)
Hydraulic Filter (large):
510 02 33-01 25 Micron fi lter
Hydraulic Filter (small):
542 16 64-49 25 Micron fi lter
NOTICE: Never use automotive type oil fi lters.
They do not have the required fl ow capacity and can burst
during operation.
Replacement Frequency:
Both Filters - After 1st 50 hours,
then every 100 hours
Hydraulic Oil - Every 100 hours
or once a year
2. Check for any leaks or kinks on the hydraulic hoses or any
other leaks at couplers and fi ttings.
3 Check oil cooler for any debris and dirt buildup. Remove
debris with air pressure or spraying with a garden hose. Do
not use a high pressure washer directly on the cooler.
WATER CONTAMINATION
In humid climates the hydraulic system can collect large
amounts of water condensation in the oil tank. This happens
due to the humid air in the tank changing from getting hot and
cold. Small amounts of water condensation will not be
noticeable. If large amounts of water are present, the oil will
“foam” or turn “white”. The power pack and other hydraulic
tools should not be operated with water contaminated oil.
If water contamination occurs you should replace the oil and
fi lters. In some cases it is feasible to remove the water
contamination out of the oil. The hydraulic hoses should also
be emptied.
Procedure for removing the water:
1. Install the hoses and connect the ends together.
2. Start the engine and turn on the fl ow selector to the
40 liters (10 gal)
3. Let the engine operate for 5 minutes at this fl ow
setting.
4. Turn of the engine and drain the oil tank in an
appropriate container. Preferably – remove the quick
couplers on the hoses and drain oil into a container.
5. The water in the contaminated oil will settle at the
bottom of the container in approximately 24 hours.
The oil will now appear “normal”.
6. Carefully pour the clean oil back into the tank –
leaving the water in the container.
7. REPLACE the oil fi lters.
REPLACING OIL AND FILTER
Remove the 4 screws as indicated below. This will enable full
access to the large oil fi lter.
ALWAYS REPLACE
both fi lters and oil
every 100 hours
OIL TANK
Drain plug.
TROUBLESHOOTING THE HYDRAULIC SYSTEM
To adequately diagnose and troubleshoot any problems relat-
ed to the hydraulic system it is necessary to have a hydraulic
tester consisting of a fl ow meter and pressure gauge. Never
readjust the pressure relief valve without the proper hydraulic
diagnostic tool.
CONTACT a local Husqvarna dealer or Husqvarna
Construction Products for diagnostic help.
