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.
screwed 'IN'). 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 necessary repairs before restarting the engine and
pressing the trigger of the lance.
5. With the lance set at high pressure, (i.e. 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:
If there is difficulty in starting the engine, particularly the diesel
model, get an assistant to fully depress the lance trigger whilst you
try to start. This will relieve any pressure in the pump making it
easier to start.
NOTE:
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 let children to hold or operate the
lance.
