5.8.1.
Stop the engine (→
Section 5.3 Shut down Procedure) and let it cool at least two minutes before removing the fuel tank cap (fig.1).
5.8.2.
Clean the fuel cap area of dirt and debris. Remove the fuel tank cap and make sure the fuel filter is in place.
5.8.3.
Fill the fuel tank (fig.1
) with fuel. Never overfill the fuel tank. Fill tank to no more than ½″ (13 mm) below the bottom of the filler neck
to provide space for expansion caused by the engine heat.
5.8.4.
Replace the fuel tank cap.
6. MaINteNaNCe - Washer
WarNING!
Maintenance should only be performed with the engine turned off and the unit disconnected from the mains water supply.

WINter storaGe
6.1.1.
Fill the pump with an antifreeze mixture before storing in a frost free, safe, dry area for the winter. Introduce the antifreeze by the following
method.
1.
Shut off the water supply and disconnect the supply hose. Relieve pressure within the pump by squeezing the gun trigger. Remove the
high pressure hose and let all water drain from it. Hold gun/lance with nozzle downwards and pull trigger until all water has drained out.
2. disconnect the ignition lead from the spark plug.
3. Connect a short length of garden hose to the water inlet and using a funnel pour an antifreeze mixture into it.
4. Pull the recoil starter several times to circulate the antifreeze through the pump. Continue to add antifreeze and pull the recoil until
antifreeze is expelled from the pump.
6.2.
CLeaNING Water INLet fILter
WarNING!
Do Not
operate this pressure washer without the water inlet filter in place, as deposits could build up internally and
affect the functioning of the unit.
6.2.1.
This pressure washer is equipped with a water inlet filter.
6.2.2.
The water inlet filter must be kept clean at all times, otherwise it can restrict the water flow to the pump unit and damage it.
6.2.3.
Remove the quick-connect coupler from the water inlet, then remove and clean the water inlet filter.
7. MaINteNaNCe - eNGINe
7.1.
Change engine oil after the first 8 hours of operation. After that, it should be replaced every 100 hours or every six months.
Change oil
more often if engine is operated under heavy load, or in high ambient air temperatures. During normal operation, partially burned fuel,
small particles of metal from the cylinder walls, pistons, bearings and combustion deposits will gradually contaminate the oil. If the oil is
not changed regularly, these foreign particles can cause increased friction and a grinding action which shortens the life of the engine.
Fresh oil also assists in cooling. old oil gradually becomes thick and loses its cooling ability as well as its lubricating qualities.
7.2.
CheCKING the oIL LeVeL.
ensure the unit is on a level surface.
7.2.1.
Unscrew the dipstick and wipe it clean of oil. note that the maximum oil level should be just below the opening of the filler neck.
7.2.2.
Check the oil level by seating the dipstick into the hole without screwing it in. If there is no oil on the dipstick when it is removed the level
is too low and should be topped up immediately with an SAe10W - 30 oil.
7.2.3.
Top up oil if necessary and recheck level.
7.2.4.
Screw dipstick fully home to seal oil fill hole.
Note:
The engine is fitted with a low oil sensor which will automatically shut the engine down in a low oil situation. The sensor may also operate
if the unit is not on a level surface.
7.3.
DraINING eNGINe oIL
7.3.1.
The engine oil should be replaced after
the first 8 hours of operation, or after the
first month of use. After that, it should be
replaced every 100 hours or every six
months.
7.3.2.
To drain the engine oil:
1. Loosen the oil tank dipstick (fig.8).
2. Place an oil container underneath the
opening on the mainframe.
3. Remove the hex (fig.6) screw and
drain the oil.
4. Once the oil has been completely
drained, retighten the hex screw
(fig.6) and oil tank dipstick.
7.4.
CheCKING aIr fILter
IMPortaNt:
Clean air filter (fig.1)
element after every 50 hours of use (every
10 hours under dusty conditions). Wash in
high flashpoint solvent, squeeze dry,
dip in clean engine oil, and squeeze out
excess oil.
7.4.1.
To access the air filter element unscrew and remove the wing nut on the top of the cover. lift the air filter cover off its threaded
mounting rod (fig.12).
7.4.2.
Remove the foam filter (fig.13) from the air intake base moulding.
7.4.3.
Wash the foam element with a household detergent or a high flash-point solvent and squeeze dry. When the element is thoroughly dry soak
it in clean engine oil. Squeeze out any excess oil, fit back over the air intake base moulding.
7.4.4.
Place the air filter cover onto the threaded rod and secure with the wing nut.
7.4.5.
The foam element should be replaced after every 300 hours of service.
