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.
