GENERAL SAFETY RULES

1. It is important to read all parts of this operator's manual carefully before
using the power washer.

2. NEVER direct the spray towards any person

or animal.

3. NEVER direct the spray towards electrical wiring

or equipment.

4. NEVER hold your finger over the

high pressure nozzle.

5. ALWAYS remember that the exhaust, exhaust gases and the metal lance
can get very ho

t during use.

6. NEVER allow children to use this machine.

7. NEVER operate the

machine with any of the covers removed.

8. NEVER attempt any repa

irs to this machine. Always refer to a qualified

service agent.

9. NEVER supply any liquid othe

r than water to the water inlet.

10. NEVER use the detergent bott

le to spray solvents, e.g. paint thinners, petrol,

oil etc.

11. ALWAYS release any residual pressure in the system by turning of

f the water
supply and operating the trigger before disconnecting any hose or
accessory.

12. NEVER disconnect the plug by pulling on the power supply cable, and
never move the power washer by pulling on the high pressure hose.

13. ALWAYS keep the machine itself dry and well clear of water spray.

14. ALWAYS wear protective clothing and safety glasses. Loose particles and
othe

r debris ma

y be propelled at high speed by the water jet.

15. ALWAYS grip the gun firmly before pressing the trigger, expect the gun to
‘kick’ when starting.

16. ALWAYS respect the requirements of the local water company. Power
washers may on

ly be connected to the mains drinking water supply, if a

backflow preventer valve is installed in the supply hose.

17. When not in use, ALWAYS disconnect from the water supply, and ensure the
system is completely drained. Store in a cool dry location.

WARNING: Water at high pressure can be dangerous and can cause
damage to persons or property if the operator is careless. Never allow
anyone to operate this equipment unless they are thoroughly reliable,
and familiar with the safety precautions.

ELECTRICAL CONNECTIONS

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 supply 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.

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 wire which is coloured Blue must be connected to the terminal which is

marked N or coloured Black.

• The wire which is coloured Brown must be connected to the terminal which is

marked L or coloured Red.

• The wire which is coloured Yellow and Green must be connected to the

terminal which is marked E or or coloured Green.

We strongly recommend that this machine is connected to the mains supply via a
Residual Current Device (RCD)

If in any doubt, consult a qualified electrician. DO NOT attempt any repairs yourself.

WARNING! Read these electrical safety instructions thoroughly
before connecting the product to the mains supply.

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

Plug must be BS1363/A approved.

Always fit a 13 Amp fuse.

Ensure that the outer sheath of the cable is firmly held by the clamp
