CAUTION: NEVER disconnect the high-
pressure discharge hose from the
machine while the system is still
pressurized. To depressurize the unit,
turn off the motor, turn off the water
supply and squeeze the trigger 2-3 times.
Water supply
• Ensure that you have a suitable water supply
to feed the pressure washer. Check that all
connections are tight and there are no leaks in
the hose.
• The supply tap should be fully open (do not
turn on the pressure washer yet).
• Now depress the trigger (unlock trigger lock
first) to let water pass through the unit and
expel any air.
Warning! This unit is to be used with a
cold-water source only!
Electrical Cables
• Ensure that all cables are damage free before
connecting to the power supply.
Plug in the pressure washer and turn the unit
on with the main switch (2).
4. USE
CAUTION! The machine may cause
electrical disturbances when starting.
• If the motor stops and fails to restart, wait 2-3
minutes before restarting. THERMAL CUTOUT

Adjusting the nozzle
Fig. 2
• Water may be sprayed out of the nozzle either
linearly or in a fan shape. Turn on the pressure
first, and then adjust the nozzle.
Adjusting te working pressure
Fig. 3
The working pressure can be adjusted by turning
the sleeve on the end of the spray gun (9).
• Turn the sleeve clockwise to increasing the
working pressure.
• Turn the sleeve counter-clockwise to reduce
the working pressure.
Water inlet filter
• The water inlet filter must be inspected regu-
larly, so as to avoid blockage and restriction of
the water supply to the pump.
CAUTION! Never disconnect the high-
pressure hose from the machine while
the system is still pressurized.
5. SERVICE & MAINTENANCE
Warning! Unplug the electric cable
(power source) prior to any maintenance
or preparatory storage operations.
• Make sure that the machine is not live when
carrying out maintenance work on the motor.
• To ensure good performance, check and clean
the suction and detergent filters after every 50
hours of operation.
Malfunction
Should the machine fail to function correctly, a
number of possible causes and the appropriate
solutions are given below:
1. When switched on, the machine will not
start working.
• Plug is not well connected or electric socket is
faulty.
• Check plug, socket and fuse.
• The mains voltage is lower than the minimum
requirement for start up.
• Check that the mains voltage is adequate.
• The pump is stuck.
• Refer to after storage instructions. Switch
off the unit and let the motor cool.
• Thermal safety has tripped.
• Leave the lance open with water coming
through.
2. Fluctuating pressure
• Pump sucking air
• Check that hoses and connections are airtight
• Valves dirty, worn out or stuck. Pump seals worn.
• Clean and replace or refer to dealer.
3. Water leaking from the pump
• Seals worn out
• Check and replace, or refer to dealer
