SYMPTOMS

COMMENTS AND POSSIBLE SOLUTIONS

Pressure Washer
No water through
the lance

Check the water supply (whenever possible connect to the mains water supply and
turn on the tap).
If connected to a water barrel always try to ensure that the barrel is higher than the
machine, and that the supply is tapped from near the base of the barrel. The lance
should not be used at an elevation above the supply source.

Pressure Washer
No high pressure
water through the
lance and the
engine under load

Blocked lance jet. Switch off machine and investigate. A blocked jet can be
cleared with a length of fine stiff wire.
Remove the lance from the handle, and sight through the lance to see if the brass
jet is obstructed. Remove any dirt, mud etc from the jet using the fine stiff wire.
Check the purity of the water supply, particularly if the supply is non-mains.
Check for a blocked filter in the quick fit hose connector.

Pressure Washer
Water through the
lance but not at the
required mode

Check the Lance nozzle setting (the supplied lance has an adjustable outlet nozzle).
The nozzle has arrows on it to aid setting selection.
Push the nozzle downwards to access ‘low pressure mode’.
Pull the nozzle upwards to access ‘ high pressure mode’.

Twist the nozzle to access pencil or fan stream in either mode.

Water Pump
Poor Dirty Water
Pump output

Pump not properly primed. Prime the pump.

Fig. 10

Air leaks in the hoses. Check particularly the input side of the pump. The hoses should
be securely fastened to the pump connector ferrules using the supplied double wire
clips. The rubber gaskets (supplied) must be fitted between the mating surfaces of
the pump body and the hose connector ferrules. The large ‘winged’ connecting collars
must be tightened securely to the pump.
Do not use a flat hose on the inlet/suction side of the pump.

SYMPTOMS

COMMENTS AND POSSIBLE SOLUTIONS

Engine will
not start

Check –

1. The ignition switch is in the ‘ON’ position.

Fig. 1

2. The Fuel Tap is turned to the ‘ON’ position.

Fig. 2

3. The Choke is correctly set for starting.

Fig. 3

4. Oil Level.

Fig. 4

Engine starts but
cuts out almost
immediately

Check –

1. The oil level is correct (low oil level will cause automatic engine shutdown).
Top up the oil level.

Fig. 4

2. That the accessory is correctly connected to the engine (a micro-switch inside
the Evo-coupling senses when an accessory is correctly connected). The engine
will not run unless a correctly connected accessory is attached to the engine.
Remove and re-attach accessory.

Fig. 5

3. Accessory is only partially connected and/or the uni-coupling release lever is not in
the locked position, allowing the accessory to vibrate loose from the engine. Remove
and re-attach the accessory and confirm that it is ‘locked’ into the engine.

Generator not running at the required speed. To work efficiently the generator must
run at 3150 min

(the factory set and governed speed of the engine). Have the

speed of the engine checked to ensure that it is operating at the factory set speed.
