3. If debris is easy to remove, move nozzle back to
cover more area for faster cleaning.
CLEANING VERTICAL SURFACES
IMPORTANT: Remember that the pressure washer
can deliver a high pressure spray that can break
glass and gouge soft wood and other materials.
When cleaning building interiors or exteriors without
detergents, work from top to bottom. This will help
eliminate streaks. In interiors, start with the ceiling
first, then the walls and the floor last.
CAUTION! Clean around windows
carefully.
and puttied, the high pressure spray could
break the glass.
CAUTION: Never spray directly overhead.
Always spray ahead to avoid dripping or
falling debris.
REMOVING PAINT
IMPORTANT: Remember that high pressure spray
can gouge soft woods and other materials, as well
as loosen grout.
1. Direct spray at a 45° angle about 10 to 30cm
from surface.
2. Spray in a back and forth motion, try to get
beneath the loose and bubbled paint.
3. Do not be concerned with the paint that remains.
It should be sufficiently bonded so as not to
cause repainting problems.
CAUTION! Never allow the pump to run
for more than a 2 minute period without
opening the gun. This will cause pump
damage due to excessive water temperature
and void the warranty. A thermal relief valve
has been added to the pump to reduce the
possibility of overheating, however,
malfunction of this device does not constitute
pump warranty for damage caused by
overheating.

Check and Clean Inlet Screen / Filter
Examine the screen on the water inlet. Clean it if the
screen is clogged or replace it if screen is damaged.
Check High Pressure Hose
The high pressure hose can develop leaks from
wear, kinking, or abuse. Inspect the hose each time
before using it. Check for cuts, leaks, abrasions or
bulging of cover, damage or movement of couplings.
If any of these conditions exist, replace the hose
immediately.
WARNING! The high pressure stream of
water that this equipment produces can
pierce skin and its underlying tissues, leading to
serious injury and possible amputation. NEVER
repair high pressure hose. Replace it. Replacement
hose rating MUST exceed maximum pressure rating
of unit.
Check Detergent Siphoning Tube
Examine the filter on the detergent tube and clean if
clogged. The tube should fit tightly on the barbed
fitting. Examine the tube for leaks or tears. Replace
the filter or tube if either is damaged.
IMPORTANT: Simply shutting OFF engine will not
release pressure in the system. When the engine

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
waterblasters
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.
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 label.
Always wear eye protection when using
PumpSaver.
NOTE: If PumpSaver is not available, draw RV
the solution into a 1 metre 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.
5. Store unit in a clean, dry area.
PS3611ES

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
sufficient 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:
Some Pressure Washer Problems
Some of the problems that might occur in a high
pressure system are as follows:
When a problem arises don't remove the pump
immediately and start replacing parts. First check
the following possible causes of the problem:

inlet (such as too many valves, or too many
bends).
To prevent cavitation, pump inlets must be carefully
maintained to avoid restrictions to flow.

Troubleshooting Tips
Problems with Detergent
Problems with use of detergent are often caused by
incorrect procedures of operator. Problems
encountered 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. Failure to flush the detergent system out with
clean water following previous use.
3. Wrong type of detergent: Only soaps designed
specifically for pressure washers should be
used. Household detergents could damage the

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.
