GENERAL SAFETY RULES
1. NEVER direct the spray towards any person or animal.
2. NEVER hold your finger over the high pressure nozzle.
3. NEVER allow children or untrained personnel to use this machine.
4. NEVER operate the machine with any of the covers removed.
5. NEVER attempt any repairs to this machine. Always refer to your Clarke dealer.
6. NEVER supply any liquid other than water to the water inlet.
7. NEVER 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 any residual pressure in the system by turning off the water supply
and operating the trigger before disconnecting any hose or accessory.
9. ALWAYS keep the machine itself dry and well clear of water spray.
10. ALWAYS wear protective clothing and safety glasses. Loose particles and other
debris may be propelled at high speed by the water jet.
11. ALWAYS grip the gun firmly and expect the spray gun to ‘kick’ when starting.
12. ALWAYS respect the requirements of the local water company. Pressure washers may
only be connected to the mains drinking 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 ensure the system is completely
drained when not in use. Store in a cool dry location.
14. ONLY use chemical cleaning agents (detergents), that are approved for pressure
washers. CLARKE Traffic Film Remover or CLARKE Wash and WAX (available from your
dealer), is recommended.
15. WARNING High pressure water jets can be dangerous if subject to misuse. The jet
must not be directed at a person or anything that they are wearing.
16. NEVER direct the jet at electrical equipment or the machine itself.
17. 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.
18. WARNING Water that has flowed through a system separator (also known as a
backflow preventer) is considered non-drinkable.
19. NEVER use the pressure washer if the inlet/outlet hoses or important parts of the
machine are damaged.
WARNING: Water at high pressure can be dangerous and can cause
damage if the operator is careless. Never allow anyone to operate this
pressure washer unless they are familiar with the safety precautions.

BEFORE USE
IMPORTANT: The engine is supplied without any oil in it and must be filled to
the correct level before use, see below.
ENGINE OIL
1. Turn the oil filler cap anticlockwise
and remove it from the engine,
wipe the integral dipstick with a
clean cloth.
2. Insert the oil filler cap back into
place and then remove it again.
3. If the oil reads low on the dipstick,
add oil to the oil reservoir (Max
0.4L).
• We recommend the use of
SAE10W-30 oil.
• Do not overfill the oil reservoir.
4. Replace the oil filler cap.
NOTE: Running the engine with
insufficient oil will cause
engine damage.
WARNING: TO CARRY OUT THIS CHECK, PLACE THE PRESSURE WASHER ON
LEVEL GROUND WITH THE ENGINE SWITCHED OFF.

INTERRUPTING OPERATION
1. Release the trigger.
NOTE: The pressure washer will automatically go into bypass mode.
NOTE: If you notice water coming from the drain tube attached to the
pump, please note that this is a safety feature and should be
expected, it cools the pump by releasing some of the hot water within
the pump and replacing it with fresh ‘cool’ water.
2. Rotate the trigger lock to the locked
position.
ADJUSTING THE SPRAY NOZZLE
The nozzle is adjustable to allow you to adjust the water delivery from a narrow
jet of water to a wide spray. To adjust the nozzle, proceed as follows:
1. Hold the shaft of the lance in one
hand.
2. Twist the nozzle with the other
hand.
• The spray varies between
narrow and wide as you turn
the nozzle.
ADJUSTING THE PRESSURE
The machine output is preset at the factory. To lower the contact pressure:
1. Back away from the surface to be cleaned. The further away you are the
less the pressure will be on the surface being cleaned.
2. Reduce the speed of the engine using the throttle. Slow the engine down
and the water pressure will also go down.
3. Adjust the spray to a wider angle.
4. Hold the rear of the nozzle and slide the front of the nozzle forwards to low
pressure and backwards for high pressure.
WARNING: DO NOT ALLOW THE UNIT TO OPERATE IN BYPASS MODE FOR
MORE THEN TWO MINUTES AT ANY TIME. TURN THE UNIT OFF IF IT IS NOT
GOING TO BE USED FOR A PERIOD LONGER THAN THIS. SEE PAGE 14.

APPLYING DETERGENTS AND CLEANING AGENTS
To improve the cleaning performance, you can introduce chemical cleaning
agents (detergents) to the water jet using the detergent pickup hose.
1. Place the detergent pickup hose
into a container holding the
chemical/cleaning solution.
• Only use detergents
recommended for use with
pressure washers, such as
CLARKE Traffic Film Remover
which is a powerful low
foaming agent for car
cleaning, patio cleaning etc.,
or CLARKE Wash & Wax, both
available from your CLARKE dealer.
2. Hold the rear of the nozzle on the
high pressure lance and slide the
front of the nozzle forwards to low
pressure.
3. Spray the detergent onto the
vehicle, patio etc.
• Allow the detergent a little time
to work itself into the grime.
4. To rinse, remove the detergent pickup hose from the container holding
chemical/cleaning solution, slide the front of the nozzle on the lance back
towards the handle and use the pressure washer as normal.
SHUTTING DOWN
1. After each use, if you have
applied chemicals, place
detergent pickup hose into a
container of clean water and run
clean water through detergent
pickup hose to flush the system
thoroughly.
2. Move the throttle control lever to
the right.
CAUTION: IF YOUR EYES COME INTO CONTACT WITH ANY CLEANING
FLUIDS, RINSE THEM IMMEDIATELY WITH PLENTY OF FRESH CLEAN WATER.
