OPERATION INSTRUCTIONS

BEFORE USE
WARNING: To carry out this check, place
the power washer on level ground with the
motor switched off.
WARNING: Take care not to touch any hot
parts of the power washer when checking the
oil levels.
IMPORTANT: The PUMP is supplied without
any oil in it and must be filled to the correct
level and proper oil before use, see below.
CHECKING THE PUMP OIL LEVEL
Look at the sight glass
on the pump to check
the oil level it should
be at the 1/2 position
of the sight glass If
required, remove the
oil filler cap and top
up with oil (Fig.8).
• We recommend the use of SAE30 oil in this
power washer, and the oil capcity is 500ml.

PRESSURE REGULATOR
When supplied the pressure regulator may be
set to minimum.
Turn the pressure
regulator on the
pump fully clockwise
to allow water pres-
sure to build up when
the pressure washer is
running (Fig.9).
If you find the pressure is too high, you can
adjust this later.
USING YOUR POWER WASHER
POWER WASHER TERMINOLOGY
Bypass mode: In bypass mode, the pump re-
circulates the water because the trigger of the
spray gun is not being pulled. If unit is left in
bypass mode for more than two minutes, the
water temperature will rise to a dangerous
level and could damage internal components
of the pump.
NOTE: Any damage to pump due to these
causes will not be covered under warranty.
Chemical Injection System: Mixes cleaners or
cleaning solvents with the pressurised water to
improve cleaning effectiveness (Fig.10-a).
Fig.10
Thermal Relief Valve: In an effort to prevent
extreme damage, pumps are equipped with
a thermal relief valve. This valve will open
when the temperature inside the pump rises
too high. This valve will then release a gush of
water in an effort to lower the temperature
inside the pump. Immediately after this occurs,
the valve will close (Fig.10-b).
Easy start Valve: During pull starting, when
the engine is turned over pressure builds in the
system, the pressure in built in the system is a
tremendous load to attempt the engine start-
ing against. The easy start valve solves these
issues, it will dischage the water when pulling
start to help the engine to easy start, when
squeeze the trigger the valve will shut of, but
