WARNING! Ensure you have read, understood and apply Section 1 safety instructions.
p
WARNING! Dry running can seriously damage the unit.
p
WARNING! DO NOT leave motor running for more than 1-2 minutes without operating the trigger, as temperature/pressure
increase may damage sealing system.
p
WARNING! While the machine is running, DO NOT cover it or place in an enclosed space with poor ventilation.
The water temperature should NOT exceed 60
p
NOTE: For instructional purposes the terms used to explain the trigger functions are :
a)
trigger depressed = open.
4.1.
Precautions before starting
If the washer has not been used for a prolonged period, turning the machine on may damage the motor. To avoid this, ensure the
washer is unplugged from the mains power supply and then turn the motor shaft by inserting the allen key (provided) through the
fan cowling located at the bottom end of the washer. This will release any blockages, deposits or lime scale. Remove the key before
plugging the washer into the mains power supply and switching on.

4.2.
Start procedure
4.2.1.
Fully open mains water tap, ensure there are no leaks from any of the hoses or connectors and that all hoses are straight.
4.2.2.
Depress the trigger to allow any air to escape, hold for 30 seconds.
4.2.3.
While holding the trigger open turn the machine on, and adjust the motor control setting knob to the desired speed setting (fig 6).
4.3.
Adjustments
WARNING! Avoid sudden bursts of water as they will cause the water pressure to drop and put extreme pressure on the hoses
and connectors. If this happens you will need to switch the machine off, and refer back to the start procedure.
p
NOTE: Always depress the trigger and hold before starting the machine.
4.3.1.
The water nozzle must only be adjusted with the trigger closed.
4.3.2.
Rotate the nozzle to make the adjustment of the water jet between pencil or fan setting (fig 7).
4.3.3.
Push the nozzle forwards for low pressure operation (suction and spraying of detergent), for high pressure operation (high pressure
washing and rinsing) pull backwards (fig 7).
4.3.4.
The water pressure will drop if someone else is using water from the same supply as the washer, If this happens switch off the
motor immediately and wait until the pressure is restored.
4.3.5.
When you have finished working, discharge residual pressure by depressing the trigger until no more water comes out of the nozzle.
4.4.
Detergent use
WARNING! Liquid detergent can only be sprayed at low pressure.
4.4.1.
Pour detergent into the opening at the top of the detergent tank located underneath the handle assembly (fig 8).
p
4.4.2.
Adjust the nozzle to low pressure with a fan setting (fig 7).
4.4.3.
The detergent strength can be adjusted by turning the detergent control knob (fig 9).
4.5
Pressure Gauge
The pressure gauge is liquid filled and indicates the output pressure in both psi and bar . Readings are only shown when HIGH
PRESSURE is used, the trigger is depressed and water is flowing through the system. Familiarise yourself with the individual
specifications shown in Section 2 and regularly check the gauge during use. Adjusting the motor speed (fig 6) will cause the gauge
to rise or fall accordingly.
4.6.
Recommended cleaning procedure
WARNING! The high pressure jet should be used with extreme caution. Ensure you aim the lance correctly at the work surface.
Failure to do so may scatter loose particles at the same speed as the water jet, resulting in possible damage or personal injury.
p
ALWAYS wear safety goggles and protective clothing.
4.6.1.
Apply detergent at low pressure to a dry surface. On vertical surfaces, work from the bottom upwards. Leave the detergent to act
for 1-2 minutes (DO NOT allow to dry out).
4.6.2.
To rinse, adjust the water jet to high pressure (this will automatically shut the detergent off). Ensure the nozzle is at least 30 cm (10’’)
from the surface. Avoid allowing the water to run onto unwashed surfaces.
4.7.
Precautions for storing
WARNING! To avoid damage to the pump protect the washer against freezing.
NOTE: If the washer is to be stored for prolonged periods and there is a danger of freezing you must:-
p
a) Mix a non-corrosive/non-toxic anti-freeze solution suitable for the expected temperature drop.
b) Disconnect the water supply hose and add the solution in 1/2 litre intervals via the water inlet with the motor running and the
trigger depressed until the solution emerges from the lance.
4.7.1.
Switch off the cleaner.
4.7.2.
Close the water supply tap.
4.7.3.
Discharge residual pressure by pressing the trigger until no more water comes out of the nozzle.
4.7.4.
Engage the gun safety catch.
4.7.5.
Thoroughly clean the water nozzle with the tool supplied (fig 10).
4.7.6.
Disconnect the plug from the mains power supply.
C (140
F). The water pressure must NOT exceed 10 bar (145 psi)
