CONNECTING THE WATER
SUPPLY
WARNING
Always wear safety goggles that
comply with AS/NZS 1337 when
operating or in the vicinity of the
pressure washer. Hearing protection,
closed shoes and long trousers should
also be worn.
NOTICE
Do not start the engine without the water supply
connected and turned on. Running the pump
without water will damage it, which is not covered
by warranty.
The water supply must be capable of delivering
a flow rate of 15 L/min (3.3 gpm) at a pressure of
at least 200 kPa (29 psi) at the pressure washer
inlet. Do not draw or siphon from a standing water
supply; connect only to a pressurised water supply.
The water temperature must not exceed 40°C
(104°F).
Ensure that the water inlet screen is in place and
clear of any obstructions before attaching the water
supply hose.
Do not operate the pressure washer with a missing,
damaged or obstructed inlet screen.
1. Run water through the hose to clear out any
debris that may be inside it.
2. Use the shortest water supply hose possible to
minimise pressure drop and maximise flow rate.
3. The inlet water connection on the pressure washer
is fitted with a standard 12 mm male quick-
connect coupling onto which a garden hose with
a standard 12 mm female quick-connect coupling
can be attached. See Figure 16.

4. Turn on the water supply and check that there are
no leaks.
5. Squeeze the trigger on the spray gun to bleed out
any entrapped air in the hoses, pressure pump
and spray gun. Continue until there is a steady
stream of water coming out from the spray nozzle
and then release the trigger.
STARTING THE PRESSURE
WASHER
DANGER
Never operate the pressure washer
in an enclosed area. Engine exhaust
contains poisonous carbon monoxide.
Only operate the pressure washer
outside and away from windows,
doors and vents.
CAUTION
Hot surfaces on the engine and pump
can cause burns. Do not touch while
the engine is running. Allow to cool
afterwards before touching.
NOTICE
The pressure washer is equipped with a low oil
shutdown switch. If the oil level is too low, the
engine will shut down automatically and cannot be
restarted until the oil is filled to the proper level.
Be sure the engine has the proper oil level before
using it. Failure to verify that the engine has the
proper oil level could result in severe engine
damage or shortened engine life.
The pressure washer may move about due to
vibration while operating on a hard surface and
should preferably be operated on level ground
where possible. Allow some slack in the water
supply hose to allow for such movement and
monitor the pressure washer to check that it does
not tip over.
The pressure pump is equipped with a thermal
relief valve to protect it from overheating damage
especially while idling for an extended period. Hot
water may be ejected from the valve’s discharge
port to allow cooler supply water into the pump.
Before starting the pressure washer, verify the
following:
• The pressure washer is properly assembled.
• The engine is full of the correct type of oil.
