PJ2500RS 8.8 12
Inlet Water Supply
Requirements
1. Inlet water supply must be a minimum of 20
PSI (1.4 bar). Attempting to operate the washer
with less than adequate water supply will cause
rapid wear of packings, valves and bearings that
will dramatically shorten pump life. Symptoms of
inadequate water supply are pump shuddering and
flattening of the supply hose.
2. Inlet water flow must be at least 125% of pump
rated flow (see the following table). Check volume
by timing how long it takes to fill a 20 litre container.
For example, a flow rate of 10 L /min would fill a
20 litre container in 2 minutes.
3. Water supply hose should be a good grade of
garden hose with a minimum inner diameter of
12mm, and no longer than 15.24m. If a longer
supply hose must be used, check to be certain
flow is at least equal to the ‘L/min Supply Required’
value for your washer (See the following table).
4. If a non-pressurised (static draw) water supply
is used, check to be certain flow is at least 125%
of pump rated flow (see the following table).
In static draw situations, water flow rate (L/min)
can be increased by elevating the water supply
tank or changing to a larger inside diameter water
supply hose.

If you used the detergent siphoning tube, you must
flush it with clean water before stopping the engine.
1. Place chemical injection siphon/filter in a bucket
full of clean water.
2. Attach black low pressure spray tip.
3. Flush for 1-2 minutes.
4. Shut off engine.
O-Ring Maintenance
Through the normal operation of your pressure washer,
o-rings, which keep the connections of the hoses and
spraygun tight and leak-free, may become worn or
damaged.
To remove a worn or damaged o-ring; use a small
flathead screwdriver to get underneath the o-ring and
pry it off.

Nozzle Maintenance
A pulsing sensation felt while squeezing the spray gun
trigger may be caused by excessive pump pressure.
The principal cause of excessive pump pressure is a
Check Oil Level
The oil level in the pump can be viewed by checking
the oil sight glass (B) on the side of the pump. The oil
level should be up to the middle of the sight glass with
the machine on level ground.
Oil Change Periods
The oil in the pump should be changed after the first
two hours of use. Following this, an oil change should
be performed when the oil becomes discoloured or
every 50 hours of use, whichever event occurs first.
CAUTION! Do not exceed the manufacturer's
maximum pressure by increasing the unloader
adjustment range. (This will void pump warranty.)

Changing the Oil
1. Ensure the machine is on a level stable surface
NOTE: Performing an oil change will be easier if the
machine has been run and the pump is still warm.
2. Place a suitable container under the pump and
remove the drain bung (C).
3. Replace the oil drain bung once all the old oil has
drained from the pump. Dispose the waste oil in
an environmentally responsible manner, ensuring
local & governmental regulations are adhered to.
4. Re-fill the pump with a quality, fresh, low foaming
SAE30 oil through the oil filler hole (A) and refit
the oil filler bung. Oil capacity = 120mls.
Pressure Adjustment
Pump pressure may be adjusted by turning the
unloader adjustment knob (E).
Pump failure is most commonly due to lack of care in
operation and poor or no maintenance rather than
manufacturing defects. Issues caused by operator
error and/or lack of correct maintenance will not be
considered under warranty.

Service Chart
1. Perform engine oil change after first 5 hours of use
and then at recommended intervals. Change engine
oil every 25 hours when used under heavy load or
in high ambient temperatures.
2. Service more frequently when used in dusty areas.
3. Air filter element may require replacement earlier
in dusty areas. A dirty air filter reduces engine
performance.
4. Unit should be serviced by authorised dealer unless
owner has proper tools and is mechanically
proficient and experienced in the repair of pressure
washers.

Protecting the Pump
To protect the pump from damage caused by mineral
deposits or freezing, use PumpSaver to treat pump.
This prevents freeze damage and lubricates pistons
and seals.
NOTE: PumpSaver is available as an optional
accessory. It is not included with the pressure washer.
Contact the nearest authorized service center to
purchase PumpSaver.
CAUTION! You must protect your unit from
freezing temperatures.
Failure to do so will
permanently damage your pump and render your unit
inoperable. Freeze damage is not covered under
warranty.
To use PumpSaver, make sure the pressure washer
is turned off and disconnected from supply water.
Read and follow all instructions and warnings given
on the PumpSaver container.
NOTE: PumpSaver will drip from pump after treatment
and will stain wood and concrete.
CAUTION! Read and follow all cautions and
warnings on the PumpSaver can label.
Always wear eye protection when using PumpSaver.
NOTE: If PumpSaver is not available, draw RV antifreeze (non-alcohol) into the pump by pouring the
solution into a 3-foot section of garden hose connected
to inlet adapter and pulling recoil handle twice.

Storage
Water shouldn’t remain in unit for long periods of time.
Sediments or minerals can deposit on pump parts
and ‘freeze’ pump action.
If you do not plan to use the pressure washer for
more than 30 days, follow this procedure:
1. Flush detergent siphoning tube by placing filter
into a pail of clean water while running pressure
washer in low pressure mode. Flush for one to
two minutes.
2. Shut off engine and let it cool, then remove high
pressure and garden hoses. Disconnect spark
plug wire from spark plug.
3. Empty pump of liquids by pulling engine recoil
handle about 6 times. This should remove most
liquid in pump.
4. Use pump saver to prevent corrosion build up and
freezing of pump.

Troubleshooting
NOTE: Most problems with pressure washers are not
a malfunction of the pump or motor!! ALWAYS trouble
shoot from water source and/or nozzle towards the
pump and motor. Example: Check water supply and
nozzle if pressure fluctuates, unit is noisy or does not
reach full pressure.
Follow these trouble shooting rules closely
With proper care and use of the pressure washer,
the unit should remain free of problems. Most problems
are caused by careless or improper use of equipment.
Operation of the unit without an inlet water supply will
result in damage to seals and other components.
Another common cause of damage is running unit for
long periods with spray gun trigger in its "Closed"
position.
The latter can result in high water temperatures,
resulting in damage to seals and other components.
Cavitation
If the water pressure falls below a certain point (called
vapor pressure) the water will begin to boil even
though the temperatures are below normal boiling
point. Tiny bubbles of vapor will then form in the
boiling water. If the vapor bubbles are carried away
to a higher pressure area in the system the vapor will
condense again and leave a cavity in the midst of the
flow. The surrounding water will then rush in to fill
these cavities. Extremely high local pressures are
then created (up to 100,000 PSI). Such high pressures
may result in erosion, turbulence, noise, vibration,
and excess wear and tear on the pump.
The pump inlet, where the pistons pull the water in,
is very susceptible to cavitation problems.
Anything that obstructs the flow of water into the pump
can result in cavitation such as:
• A clogged water inlet filter
• Inlet piping or hoses that are too small
Some Pressure Washer Problems
Some of the problems that might occur in a pressure
washer system are as follows:
• Failure of the unit to produce pressure
• Erratic pressure
• Chattering
• Reduction in pressure
• Low water volume
When a problem arises don't remove the pump
immediately and start replacing parts. First check the
following possible causes of the problem:
• Make sure the water supply is turned on and the
water supply is adequate.
• Make sure the water inlet hose is not kinked or
damaged.
• Check the inlet water filter. Clean or replace if
necessary.
• Make sure the water supply is not too hot. Inlet
water temperature should not exceed 40° C.
• If a detergent is being used, make sure the
detergent hose is submerged and not drawing air
into the system. If detergent is not being used,
the chemical injector valve should be turned off.
• Make sure the unloader/regulator valve is properly
adjusted.
• Make sure the pump outlet hose is not leaking
and is not blocked.
• Check the wand and high pressure hose quick
couplers for missing O-rings.
• Check that the nozzle is clear and unobstructed.
• Excessive numbers of restrictions in the water
inlet (such as too many valves, or too many bends).
• Excessive turbulence or heat

Problems with Detergent
Problems with use of detergent are often caused by
incorrect procedures of operator. Problems encount-
ered that involve the use of cleaning agents can often
be attributed to one or more of the following:
1. Hose is not fully submerged in solution: If the tube
isn’t fully immersed, the unit will be picking up air.
2. Injection valve is closed: The detergent valve must
be open in order to pick up detergent.
3. Wrong type of detergent: Only soaps designed
specifically for pressure washers should be used.
Household detergents could damage the pressure
washer.
Engine will not start or stops while operating:
Low-oil shutdown: Fill engine with oil
Engine switch not in ‘ON’ position: Turn switch ‘ON’
Pressure built up in hose: Squeeze trigger while starting
Engine is overloaded:
Nozzle partially blocked: Clean Nozzle
Excessive pressure: Shorten the spring coil on the unloader
Pressure increases when gun is locked:
Bypass valve blocking: Clean the bypass valve
3. Damage to the pump can result from
a) Inadequate water supply,
b) Vacuum lift too high, or
c) Excessive water temperature.
4. Check the pump crankcase for correct oil level and
for oil contamination. If oil appears milky, water
has entered the oil and the piston seals should be
replaced.
1. If the pump is running but produces no flow, try
priming the pump.
a) To prime the pump, keep suction at a
minimum and keep the discharge line open.
b) Open and close the spray gun trigger
repeatedly to aid the priming process.
2. A chattering noise usually indicates a restricted
water supply or air leaks.
a) Check for kinks or leaks in the hoses
b) Look for a plugged or damaged inlet water filter
c) If the filter has been damaged, sediment may
have entered the pump. The sediment will be
lodged in the inlet valve(s) and must be removed.
Troubleshooting Tips
Engine is running but pump won’t build maximum pressure or has irregular pressure:
Faucet closed: Open faucet
Unit has been stored in freezing temperature: Thaw out unit completely
Inadequate water supply: Provide a minimum of 12L/min at 20 PSI
