Filling the Fuel Tank
CAUTION: Risk of fire. Handle fuel carefully.
Do not add fuel when product is operating. Stop
engine and allow engine to cool for two minutes before
refueling. Hot surfaces can cause burns and ignite
spilled fuel. Do not touch muffler.
•Fill fuel tank outdoors away from flames and open
sparks.
•Do not smoke when filling fuel tank.
•Do not overfill fuel tank. (There should be no fuel
in filler neck.)
•Avoid spilling fuel. Wipe clean after refueling.
•Move from refueling area before starting.
•Prevent fires by keeping engine clean of
accumulation, grease, trash and debris.
IMPORTANT: Do not permit
dirt or other foreign matter
to enter the fuel system. This
will cause hard starting, poor
performance and engine
damage. Always use clean
fuel storage containers and
funnels.
Use clean, fresh, lead-free
gasoline. Do not use stale
gasoline or gasoline that has
been stored for a long
time. Stale gasoline does not vaporise properly,
causing hard starts. Use of Fuel Set gasoline stabilizer
is highly recommended . Use of leaded gasoline or
gasohol is NOT recommended.

IMPORTANT: To avoid pump damage, you must
assemble the nozzle extension to the spray gun and
attach all hoses before you start the engine.
1. Uncoil high pressure hose and attach the end of
the hose to base of spray gun (Fig. 2). Thread
hose fitting on in clockwise direction and tighten
moderately.
3. Similarly, attach other end of high pressure hose
to high pressure outlet on pump.
4. Before connecting garden hose to water inlet,
inspect inlet screen (Fig. 3). Clean screen if it
contains debris, replace if damaged. DO NOT RUN
PRESSURE WASHER IF SCREEN IS DAMAGED.
5. Run water through garden hose for 30 seconds to
clean out any debris. Turn off water.
IMPORTANT: DO NOT siphon standing water for the
water supply. Use ONLY cold water (less than 40°C).
6. Connect garden hose (not to exceed 50 feet in
length) to water inlet (Fig. 3).
POWERJET HIGH PRESSURE CLEANER
8.

CAUTION! There MUST be at least ten feet
of unrestricted garden hose between the
pressure washer inlet and any flow shut off device,
such as a ‘Y’ shut-off connector or other con-
venience-type water shut-off valve. Damage to
equipment resulting from failure to follow this instruction
will void warranty.
7. Turn ON water and squeeze trigger on spray gun
to purge pump system of air and impurities.
!5. Adding on extension to the supply hose will
reduce water flow rates. Check for adequate
water flow rate each time an extension is added.
Water flow rates can be increased by using the
largest possible internal diameter supply hose.
IMPORTANT: Inlet water temperature must not be
more than 40°C or damage to the pump may result.
Washer Rated Flow L/min Supply

Inlet Water Supply
Requirements
1. Inlet water supply must be a minimum of 20
PSI (1.4 bar). Attempting to operate the washer
with less than adequate water supply will cause
rapid wear of packings, valves and bearings that
will dramatically shorten pump life. Symptoms of
inadequate water supply are pump shuddering and
flattening of the supply hose.
2. Inlet water flow must be at least 125% of pump
rated flow (see the following table). Check volume
by timing how long it takes to fill a 20 litre container.
For example, a flow rate of 10 L /min would fill a
20 litre container in 2 minutes.
3. Water supply hose should be a good grade of
garden hose with a minimum inner diameter of
12mm, and no longer than 15.24m. If a longer
supply hose must be used, check to be certain
flow is at least equal to the ‘L/min Supply Required’
value for your washer (See the following table).
4. If a non-pressurised (static draw) water supply
is used, check to be certain flow is at least 125%
of pump rated flow (see the following table).
In static draw situations, water flow rate (L/min)
can be increased by elevating the water supply
tank or changing to a larger inside diameter water
supply hose.
Operating Checklist
IMPORTANT: Before starting the engine review the
unit’s assembly to confirm you have performed all of
the following:
1. Make sure handle is in place and secure.
2. Check that oil has been added to proper level in
engine crankcase and the pump.
3. Add proper fuel to fuel tank.
4. Check for properly attached hose connections.
5. Check to make sure there are no kinks, cuts, or
damage to high pressure hose.
6. Provide a proper water supply (not to exceed 40°C)
