4.8.4.
The pump will only self prime to a maximum height between pump and surface of supply (suction head) of 1 m. Above this height, the
pump will not achieve suction.
4.8.5.
In case of difficulty in priming the pump, turn the engine off and remove the high pressure hose. With suction filter immersed, restart the
engine and run until water emerges from the pump outlet; stop the engine, reconnect the high pressure hose and restart.

using sPray nozzLe
4.9.1.
This pressure washer comes with five different nozzles that can be installed on the metal wand (fig.1).
4.9.2.
The spray pattern is adjusted by installing the appropriate spray nozzle.
4.9.3.
0° (red): Thin and powerful stream of water for difficult stains and debris removal
4.9.4.
15° (yellow): Thin-angled spray for detailed cleaning
4.9.5.
25° (green): Medium-angled spray for detailed cleaning
4.9.6.
40° (white): Large pattern for wider cleaning applications
4.9.7.
Detergent (black): This nozzle must be used together with a cleaning detergent at a low pressure. Use only this nozzle when using a
detergent. Use Sealey Car Shampoo, SCS006 (5ltr). Traffic Film Remover is also available, SCS002 (25ltr) or SCS001 (5ltr).
4.9.8.

4.9.9.
Pull the coupler ring back and insert the desired nozzle.
4.9.10.
Release the coupler ring to lock it back in place.
Warning!
‰
a) Avoid sudden bursts of water as this will cause the water pressure to drop and put extreme pressure on the hoses and connections.
b) If another person is using water from the same supply as the washer, the water pressure will drop. Switch the engine off immediately
and wait until the pressure is restored.
4.10.
engine LubriCation
4.10.1.
The pressure washer engine is shipped from the factory without
oil. Do not attempt to start the engine before the sump has
been filled with the correct amount of oil. Refer to the
section 5.7.

fueL
4.11.1.
Fill the petrol tank with fresh unleaded petrol. Keep fuel level
on or below the fuel level indicator in the fuel filter which sits
in the neck of the tank.

Water suPPLy (CoLD Water onLy)
4.12.1.
The unit must be used with cold water supply only. The water
hose must be at least ½" (13 mm) in diameter.
4.12.2.
The water flow rate must not fall below 18 litres per minute
(LPM) (4 gallons per minute (GPM)), or the pump might be
damaged. The flow rate can be determined by running water
for one minute into an empty container.
4.12.3.
The water supply temperature must not exceed 40°C (104°F).
4.13.
aDJusting Water Pressure
4.13.1.
The water pressure can be adjusted using the throttle (fig.9).
4.13.2.
Move the switch to FAST position to increase the engine speed, thus increasing the water pressure. Move it towards SLOW position to
decrease the engine speed, thus decreasing the water pressure.
