2. DO NOT hold your finger over the high pressure nozzle.
3. DO NOT let children or untrained personnel use this machine.
4. DO NOT operate the machine with any of the covers removed.
5. DO NOT try to repair this machine. Always refer to your CLARKE service
department for all repairs.
6. DO NOT supply any liquid other than water to the water inlet.
7. DO NOT use the detergent pickup facility to introduce flammable liquids/solvents,
e.g. paint thinners, petrol, oil as there is a risk of explosion.
8. ALWAYS release the remaining pressure in the system; turn off the water supply
and operate the trigger before you remove hoses or accessories.
9. ALWAYS keep the machine dry and away from the water spray.
10. ALWAYS use protective clothing and safety glasses. Loose particles and other
items can be propelled at high speed by the water spray.
11. ALWAYS hold the gun securely & expect it to ‘kick’ when you pull the trigger.
12. ALWAYS respect the requirements of the local water company. Pressure washers
may only be connected to the mains water supply if a system separator (also
known as a backflow preventer) is installed in the supply hose.
13. ALWAYS disconnect from the water supply, and make sure that you drain the
system when not in use. Keep in a cool dry location.
14. ONLY use detergents that are suitable for pressure washers, we recommend that
you use CLARKE Traffic Film Remover or CLARKE Wash and Wax (available from
your dealer).
15. WARNING High pressure water jets can be dangerous, the jet must not be
directed at a person or anything that they are wearing.
16. WARNING High pressure hoses, fittings and couplings are important for the
safety of the machine. Use only hoses, fittings and couplings recommended by the
manufacturer.
17. WARNING Water that passes through a system separator (also known as a
backflow preventer) is not safe to drink.
18. DO NOT use the pressure washer if there is damage to the inlet/outlet hose or the
machine.
ALWAYS: Read this manual and make sure that all warnings and
instructions are clear before you use this pressure washer.
DANGER: Risk of fire or explosion. Stop the engine before you refuel
the pressure washer. Keep flammable materials away from the work
area. Do not spray flammable liquids.
DANGER: R isk to brea thi ng. En gine exh aus t fumes can kill.
For outdoor use only. Work in a well ventilated area.

exhaust components. Don't allow hoses to contact the engine
muffler during or after use.
3. Refuel in a well-ventilated area
before starting the engine. If the
engine has been running, allow it to
cool. Refuel carefully to avoid spilling
fuel. Do not fill above the fuel strainer
shoulder.
4. After refueling, replace the fuel filler
cap securely.
RECOMMENDED FUEL
Use unleaded petrol with an octane
rating of 86 or higher. Do not overfill.
PRESSURE REGULATOR
When purchased, the pressure regulator
may be set to minimum.
Turn the pressure regulator on the pump
fully clockwise to allow water pressure to
increase when the pressure washer is
running.
If you find the pressure is too high, you
can adjust this later by turning the
regulator anti-clockwise.
SAFETY FEATURES
Bypass mode: In bypass mode, the pump recirculates the water because the trigger
of the spray gun is not being pulled. If the unit is left in bypass mode for more than
two minutes, the water temperature will rise to a dangerous level and could damage
internal components of the pump.
NOTE: Any damage to the pump due to these causes will not be covered under
warranty.
Thermal Relief Valve: In an effort to
prevent damage, pumps are equipped
with a thermal relief valve. This valve will
open when the temperature inside the
pump becomes too high. The valve will
then release a gush of water in an effort
to lower the temperature inside the
pump. Immediately after this occurs, the
valve will close.
7. If you are starting the power washer
‘cold’ set the choke lever to the
CHOKE position (left). If the power
washer is warm then set the lever to
the ‘RUN’ position.
8. Turn the ignition key to the ‘ON’
position, then turn the key to the
‘START’ position and hold it there
until the engine starts. If the engine
fails to start within 5 seconds, then
release the key and wait at least 10
seconds before operating the starter
again.
9. When the engine starts, slowly move
the choke lever to ‘RUN’ position, as
engine warms.
NOTE: If the engine starts to falter,
move choke lever to ‘CHOKE’
position, then slowly back to
‘RUN’ position.
NOTE: Using the electric starter for more than 5 seconds at a time will
overheat the starter motor and can damage it.
NOTE: Allow the engine to run at no load, low pressure for 5 minutes after
1. Pull the trigger on the gun to start water flow.
•Stand on a stable surface and grip the gun/spray wand firmly with both
hands.
•Expect the gun to kick when the trigger is pulled.
2. Release the trigger to stop water flow.
NOTE: The power washer will automatically go into bypass mode. In bypass
mode, the pump recirculates the water because the trigger of the spray
gun is not being pulled. If the unit is left in bypass mode for more than
two minutes, the water temperature will rise to a dangerous level and
could damage internal components of the pump.
WARNING: DO NOT ALLOW THE UNIT TO OPERATE IN BYPASS
MODE FOR MORE THAN TWO MINUTES AT ANY TIME.
ADJUSTING THE SPRAY
The nozzle is adjustable to allow you to change the spray from a narrow jet of water
to a wide spray.
To adjust the nozzle, proceed as follows.
1. Hold the shaft of the spray wand in one hand.
2. Twist the nozzle with the other hand.
3. To vary the spray between narrow and wide, turn the nozzle counter-clockwise
through a half-of-a-turn.
•Slide the nozzle forward for low pressure and backwards for high pressure.
ADJUSTING THE PRESSURE
There are 4 ways to adjust the pressure.
1. Adjust the pressure regulator on the
pump. Turn the pressure regulator
knob counter clockwise to lower
pressure. Once you have finished
using your power washer, return the
pressure regulator to its original
position.
2. Back away from the surface to be
cleaned. The further away you are,
the less the pressure will be on the
surface being cleaned.
3. Reduce the speed of the engine (RPM). Slow the engine down and the water
pressure will also go down.
4. Adjust the spray to a wider angle.
•Slide the nozzle forward for low pressure and backwards for high pressure.
APPLYING DETERGENTS AND CLEANING SOLVENTS
1. Push the detergent hose onto the
ribbed fitting as shown.
2. Place the other end of the detergent
hose with the filter on it, into a
