GENERAL SAFETY RULES
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.
1. NEVER direct the spray towards any person or animal.
2. NEVER direct the spray towards electrical wiring or equipment.
3. NEVER hold your finger over the high pressure nozzle.
4. NEVER allow children or untrained personnel to use this machine.
5. NEVER operate the machine with any of the covers removed.
6. NEVER attempt any repairs to this machine. Always refer to your CLARKE dealer.
7. NEVER supply any liquid other than water to the water inlet.
8. NEVER use the detergent bottle to introduce flammable liquids/solvents, e.g.
paint thinners, petrol, oil as there is a risk of explosion.
9. NEVER direct the jet at electrical equipment or the machine itself.
10. NEVER use the pressure washer if the power cable or important parts of the
machine are damaged.
11. ALWAYS release any residual pressure in the system by turning off the water
supply and operating the trigger before disconnecting any hose or accessory.
12. ALWAYS keep the machine itself dry and well clear of water spray.
13. ALWAYS wear protective clothing and safety glasses. Loose particles and other
debris may be propelled at high speed by the water jet.
14. ALWAYS grip the gun firmly and expect the spray gun to ‘kick’ when starting.
15. 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 (known as a backflow preventer) is installed in the supply hose.
16. ALWAYS disconnect from the water supply and ensure the system is completely
drained when not in use. Store in a cool dry location.
17. 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.
18. WARN IN G: 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.
19. WARN IN G: High pressure hoses, fittings and couplings are important for the
safety of the machine. Only use hoses, fittings and couplings recommended by
the manufacturer.
20. WARN IN G: Water that has flowed through a system separator (known as a
backflow preventer) is considered non-drinkable.

WARNING: READ THESE ELECTRICAL SAFETY INSTRUCTIONS
THOROUGHLY BEFORE CONNECTING THE PRODUCT TO THE MAINS
SUPPLY.
Before switching the product on, make sure that the voltage of your electricity supply is
the same as that indicated on the rating plate. This product is designed to operate on
230VAC 50Hz. Connecting it to any other power source may cause damage.
This product may be fitted with a non-rewireable plug. If it is necessary to change the
fuse in the plug, the fuse cover must be refitted. If the fuse cover becomes lost or
damaged, the plug must not be used until a suitable replacement is obtained.
If the plug has to be changed because it is not suitable for your socket, or due to
damage, it should be cut off and a replacement fitted, following the wiring instructions
shown below. The old plug must be disposed of safely, as insertion into a mains socket
could cause an electrical hazard.
WARNING: THE WIRES IN THE POWER CABLE OF THIS PRODUCT ARE
COLOURED IN ACCORDANCE WITH THE FOLLOWING CODE:
BLUE = NEUTRAL BROWN = LIVE YELLOW AND GREEN = EARTH
If the colours of the wires in the power cable of this product do not correspond
with the markings on the terminals of your plug, proceed as follows:
• The blue wire must be connected to the terminal marked N.
• The brown wire must be connected to the terminal marked L.
• The yellow and green wire must be connected to the terminal marked
E or
We strongly recommend that this machine is connected to the mains supply
via a Residual Current Device (RCD).

OPERATION
SWITCHING ON/OFF
1. Rotate the switch to the required
setting.
•0 - OFF
• 1 - ON (cold wash)
• Flame symbol - Hot Wash
AUTOMATIC STOP SYSTEM
The Automatic Stop system stops the machine during the bypass mode.
The Automatic Stop system will stop the machine and will restart it
automatically when the trigger is pulled.
• It is advisable to activate the safety lock on the gun assembly
whenever the machine is not being used in order to avoid
unintentional starting.
• If the machine starts automatically without pressing the gun trigger
this will be attributable to air bubbles in the water or other similar
phenomena and does not imply the existence of any defects in the
machine.
• Do not leave the machine unattended.
• If you do not intend to used the machine for more than 5 minutes,
turn the switch to the (0) OFF position.
CHANGING THE SPRAY PATTERN (PENCIL JET / FAN SPRAY)

ADJUSTING THE PRESSURE
1. Hold the rear of the nozzle and
slide the front of the nozzle
forwards for low pressure and
backwards for high pressure.
• Other ways to adjust the
pressure include varying the
distance you are from the
surface being cleaned or
adjusting the spray to a wider
angle (lowering the pressure).
USING DETERGENTS
WARNING: THE USE OF UNSUITABLE CLEANING AGENTS MAY ADVERSELY
AFFECT THE SAFETY OF THE MACHINE. DO NOT EXCEED THE CORRECT
OPERATING TEMPERATURE FOR THE DETERGENT IN USE.
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.
•CLARKE Wash & Wax.
1. Fill the detergent bottle with the required detergent.
2. Attach the detergent bottle to the gun assembly.
