SET-UP
WARNING! ALWAYS use the pressure washer in the upright position.
4.1
Connecting the water supply. Use a reinforced hose pipe with an internal
diameter of 1/2" and connect to the mains water supply.
Connect a push fit hose connector to the water inlet on the machine (fig.2).
The water supply should have a minimum pressure of 1.5 bar and a maximum
pressure of 6 bar, with a minimum flow rate of 7ltr/min.
Note: Ensure that the inlet filter (fig.1.3) is fitted into the water inlet before use.
4.2
Connecting the high pressure hose.
Attach the high pressure hose as indicated in fig.3 ensuring that the connector is
tight. Turn on the water supply.
4.3
Assembling the lance and nozzle.
Push the gun onto the lance as shown in fig.4 and turn through 90
into place. Insert the nozzle required into the end of the lance and screw it down.
When the nozzle is seated give it a final twist so that it clicks into place. fig.1.2 is
the variable nozzle with adjustable spray pattern. fig.1.16 is the Rotablast nozzle.

5. OPERATION
WARNING! Ensure you read, understand and apply Section 1 safety instructions.
WARNING! Dry running can seriously damage the unit.
WARNING! DO NOT leave washer switched on for more than 15 minutes without operating trigger.
Important! The washer motor will stop as soon as the gun trigger is released and will
restart when the trigger is squeezed. Always allow at least 5 seconds between releasing
the trigger and restarting.
5.1
Primary checks. Check that the inlet filter is clean; pump delivery and pressure will be
reduced if blocked. Never use the machine without a filter (which is fitted inside the
hose connector, see fig.1.3).
Ensure that the water supply, high pressure hose and gun are correctly connected, and
that air can freely circulate around the washer.
5.2
Operation of safety catch. To prevent accidental operation of the unit the safety catch should always be engaged when the gun is
not in use. Swing the catch into position over the end of the trigger as shown in fig.5. To release the catch press it above the trigger as
indicated in fig.5.
5.3
Bleeding The Gun It is very important to bleed the gun before using the pressure washer. Squeeze the trigger BEFORE turning the
electrical supply on. This allows any air trapped inside the pressure washer and gun to be removed before using the unit. Continue
holding the trigger for approximately one minute to allow any excess air out of the unit. Water will flow through the gun at low pressure
during this procedure.
5.4
Operating the machine. Hold the spray gun firmly to counteract the recoil caused by the high pressure of the water. Before switching
on ensure that the lance is not directed at people, objects or animals prior to being directed at the object to be cleaned. Depress the
trigger before switching on the unit before every use. Switch the machine on by pressing the button marked 'I' as shown in fig.1.9.
Release the safety catch (see fig.5). Point the lance at the object to be cleaned and fully depress the trigger. (When the trigger is
released the motor will automatically switch off).
5.5
Adjusting spray pattern. The fan nozzle can be continuously varied from a fine pencil jet to a fan pattern by rotating the body
of the nozzle.
Caution! The pencil point setting is very aggressive. It is recommended that for most cleaning applications, a twenty degree spray angle is
used to avoid damage to the surface being sprayed.
Note: The pressure of the spray on the surface you are cleaning increases as you move the nozzle closer to the surface.
5.5.1
For the high pressure turbo spray fit the turbo nozzle. This nozzle is intended for maximum cleaning affect.
