4. ASSEMBLY
4.1. Connecting the water supply.
4.1.1.
Use a reinforced hose pipe with an internal diameter of 1/2”(13mm) and connect to the mains water supply. Before attaching the hose
to the pressure washer flush the hose through with some clean water to remove any foreign matter from within the hose.
4.1.2. Connect
female quick conection hose fitting to the clear inlet filter on the front of the machine (fig.1).
4.1.3. Push the nozzle into the gun as shown in fig.2 (1 and 2) and screw the threaded male lance connector into the gun, ensuring that the
connection is tight.
4.2.
Connecting to mains electrical supply.

Ensure the On/Off switch (fig.4.1) is in the ‘Off’ position.
Using an RCD plugged into a 13A mains socket (PW3500 only),

5. OPERATION
operation
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.
5.1.1.
Check that the inlet filter is clean; pump delivery and pressure will be reduced if blocked. Ensure that the water supply, high
pressure hose and gun are correctly connected, and that air can circulate around the washer freely.
5.2.
Operation of safety catch.
5.2.1.
To prevent inadvertent operation of the unit the safety catch should always be engaged when the gun is not in use. Open the safety
catch as in fig.2.3 to lock the trigger against the guard.
5.3.
Bleeding the gun.
5.3.1.
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.
5.3.2.
Water will flow through the gun at low pressure during this procedure.
5.4.
Changing lances.
5.4.1.
To change the Rotablast lance for the fan jet lance, unscrew the lance from the gun as in fig.3. and replace with other lance.
Ensure the lance is tight in the gun.
5.4.2.
The spray pattern of the fan jet lance can be varied by rotating the spray head (see fig.7).
5.4.3.
WARNING!
The pencil jet is extremely aggressive and must be used with great care. The use of a fan nozzle is recommended for
general cleaning.
