6.3.5.
Discharge residual pressure from the washer by pressing the trigger until no more water comes out of the nozzle.
6.3.6.
Engage the gun trigger safety catch.
6.3.7.
In an emergency turn the engine switch to the OFF position.
CAUTION!
a) Avoid sudden bursts of water as this will cause the water pressure to drop and put extreme pressure on the hoses and
connections.
b) If another person is using water from the same supply as the washer, the water pressure
will drop and the washer
will not operate correctly. Switch the engine off immediately and wait until the pressure is restored.

USING SUCTION HOSE
6.3.8.
Connect the suction hose to the pump inlet (fig.6).
6.3.9.
Put the inlet filter into water supply.
6.3.10. Start the engine and operate as normal.
6.3.11. T
he filter must stay submerged completely.
6.3.12. T
he pump will only self-prime to maximum height between pump and surface of supply (suction head) of 1mtr. Above this height, the
pump will not achieve suction.
6.3.13. I
n case of difficulty in priming the pump, turn engine off and remove the high pressure hose. With suction filter immersed, restart the
engine and run until water emerges from the pump outet; stop the engine, reconnect the high pressure hose and restart.
7. MAINTENANCE - WASHER
Maintenance should only be performed with the engine turned off and the unit disconnected from the mains water supply.
7.1.
CLEANING THE NOZZLES
7.1.1.
Pull back the brass sleeve on the end of the lance and pull out the nozzle. Clean the nozzle with wire provided (fig 9). If this does not
improve the flow from the nozzle it should be replaced.
7.2.
Check and clean the water inlet filter every 50 operating hours. The filter is moulded into a rubber washer. Unscrew the brass connector
from the black fitting on the water inlet on the pump. Push the black fitting backwards which will eject the filter/washer and then clean the
filter washer. If the filter is damaged in any way it should be replaced.
7.3.
Check and clean the detergent filter at the end of the detergent input tube on a regular basis.
7.4.
WINTER STORAGE
7.4.1.
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.
7.4.2.
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.
7.4.3.
Connect a short length of garden hose to the water inlet and using a funnel pour an antifreeze mixture into it.
7.4.4.
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.
8. MAINTENANCE - ENGINE
8.1.
Change engine oil after the first 8 hours of operation. Thereafter, change oil monthly or every 50 hours of operation.
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.
8.2.
CHECKING THE OIL LEVEL
8.2.1.
Ensure the unit is on a level surface.
8.2.2.
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.
8.2.3.
Check the oil level by seating the dipstick into the hole without
screwing it in. See fig.8 above. 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.
8.2.4.
Top up oil if necessary and recheck level.
8.2.5.
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.
8.3.
ENGINE STORAGE
8.3.1. If the unit is not to be used for more than one month the following procedure should be followed.
8.3.2.
Top-up engine oil to maximum.
8.3.3.
Drain petrol from the fuel tank, fuel line, fuel tap and carburettor.
8.3.4.
Pour one teaspoon of engine oil through the spark plug hole, pull the recoil starter several times and replace the spark plug. Then
pull the starter slowly until an increase in pressure is felt indicating that the piston has commenced its compression stroke and leave it in this
position. This closes both the intake and exhaust valves and prevents the inside of the cylinder from rusting.
7.3.4.
Cover the unit and store it in a clean dry place that is well ventilated and away from open flame or sparks.
