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 supply 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. 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. High-pressure hoses, fittings, and couplings are important for the safety of the machine. Use only hoses, fittings, and couplings recommended by the manufacturer.
20. Water that has flowed through a system separator (known as a backflow preventer) is considered non-drinkable.

ELECTRICAL CONNECTIONS

WARNING: READ THESE ELECTRICAL SAFETY INSTRUCTIONSmnTHOROUGHLY BEFORE CONNECTING THE PRODUCT TO THE MAINS SUPPLY.

Connect the mains lead to a standard, 230 Volt (50Hz) electrical supply through an approved 13 amp BS 1363 plug, or a suitably fused isolator switch. 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 because of damage, it must be removed and a replacement fitted, following the wiring instructions shown below. The old plug must be discarded safely, as insertion into a power 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 do not agree with the markings on the plug.

• The BLUE wire must be connected to the terminal which is marked N or coloured black.
• The BROWN wire must be connected to the terminal which is marked L or coloured red.
• The YELLOW AND GREEN wire must be connected to the terminal which is marked E or coloured green.

3. To vary the spray between narrow and wide, turn the nozzle counterclockwise through a half-a-turn (180°).

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.
2. Other ways to adjust the pressure include Increasing the distance you are from the surface being cleaned and adjusting the spray to a wider angle (lowers the pressure).

APPLYING CHEMICALS AND CLEANING AGENTS

To improve the cleaning performance, you can introduce chemical cleaning agents (detergents) to the water jet using the detergent tank. This is particularly useful when washing cars, greasy engine parts, or removing oil spots on concrete etc.

CAUTION: IF YOUR EYES COME INTO CONTACT WITH ANY CLEANING FLUIDS, RINSE THEM IMMEDIATELY WITH PLENTY OF FRESH CLEAN WATER AND SEEK MEDICAL ADVICE IF REQUIRED.

To prepare for detergent application

1. Remove the detergent filler cap and fill the tank with detergent.

• Only use detergents recommended for use with pressure washers such as Clarke Traffic Film remover for car cleaning, patio cleaning etc., or CLARKE Wash & Wax, both available from your CLARKE dealer.

2. Disconnect from the power supply.
3. Wind the hose onto the reel and put the spray gun/lance into the holder on the power washer.

STORAGE PROCEDURE

Disconnect from the water supply, and ensure the system is completely drained when not in use. Store in a cool dry location. Avoid storing the power washer at freezing temperatures. Residual water in the high-pressure pump of hose assembly may cause permanent damage to the components if it freezes.

MAINTENANCE

WARNING: REMOVE THE PLUG FROM THE SOCKET-OUTLET BEFORE CLEANING OR MAINTENANCE AND WHEN REPLACING PARTS.

CLEANING THE NOZZLE

If the nozzle becomes partially clogged with foreign material such as dirt or limescale, excessive pressure may develop and the pump pressure will pulsate. Clean the nozzle immediately as follows:

1. Turn off the power washer and turn off the water supply.
2. Pull the trigger to relieve any water pressure.
3. Disconnect the lance from the spray gun.
4. Remove any obstructions by,directing the water supply into the end of the lance for 30 seconds to back flush loose particles.
5. If flushing does not dislodge the obstruction, carefully use the nozzle cleaning tool, to clear the nozzle.
6. Reconnect the lance to the gun and turn on the water supply.

CLEANING THE WATER INLET FILTER

This filter should be checked periodically and cleaned if necessary.

1. Remove the inlet filter from the pressure washer as shown.
2. Clean the filter by flushing both sides with water.
3. Replace the filter into the water inlet.
   • The tapered side faces in.

NOTE: Do not operate the pressure washer without the filter installed.
