OPERATION
1. Turn the water supply fully ON at the mains.
2. Refer to the engine handbook, and start the engine. Move the speed lever to
MAX.
3. To set the lance at high pressure, turn the hand grip of the
lance clockwise (i.e. screw it ‘IN’), as far as it will go.
Low pressure is set by screwing the grip ‘OUT.
NOTE: Low pressure setting is used for
detergent spraying.
4. Check that there are no leaks
in the line connections. Switch
off the engine and make the
necesary repairs before re-
starting the engine, and pressing the trigger of the lance.
5. With the lance set at high pressure, (i.e. the hand grip screwed ‘in’), the pressure
may be regulated by turning the adjuster knob on the unloader valve.
6. The low pressure setting is used for detergent pick-up (see below).
ALWAYS ensure the filter is attached to the end of the pick-up tube, and is
completely submerged in the detergent. It is not necessary to adjust the
pressure at the unloader valve when set to low pressure.
NOTE:
1. If there is any difficulty in starting the engine, particularly the diesel model, get
an assistant to fully depress the lance trigger whilst you attempt to start. This
will relieve any pressure in the pump so that there is no load on the engine,
making for an easier start.
2. Be aware that the pump delivers a considerable pressure. If the lance is set to
high pressure and the trigger is depressed, you will experience a kick back.
Ensure you are prepared for this, and hold the lance firmly. DO NOT allow
children to hold or operate the lance.
CHEMICAL CLEANING AGENTS
To improve cleaning qualities, chemical cleaning agents (detergents) may be
injected into the low pressure spray. This is particularly useful for washing cars,
greasy engine parts, oil spots on concrete etc.
To inject a detergent, insert the clear plastic hose with filter attachment into the
detergent container, ensuring it is completely submerged.
N
OTE: Use ONLY detergents designed for use with power washers. We recommend
the use of CLARKE Traffic Film Remover, which is a powerful low foaming agent,
for car cleaning, as well as other cleaning tasks.
When detergent injection is required, screw the lance hand grip ‘out
(anticlockwise), to the low pressure setting, and the detergent will automatically
