ADJUSTING THE SPRAY PATTERN (Fig.24)
You have the choice of 4 different colour coded nozzles giving you different spray patterns to choose from:
0° nozzle (Red):This nozzle delivers a pinpoint stream and is extremely powerful. It covers a very small
area of cleaning. This nozzle should only be used on surface that can withstand this high pressure such as
metal or concrete. Do not use on wood.
15°nozzle (Yellow):This nozzle delivers a powerful 5 degree spray pattern for
intense cleaning of small areas. This nozzle should only be used on areas that
can withstand the high pressure from this nozzle.
40°nozzle (White):This nozzle delivers a 40 degree spray pattern and a less
powerful stream of water. It covers a wide area of cleaning. This nozzle should
be used for most general cleaning jobs.
Low pressure nozzle (Black): This nozzle is used to apply chemicals or
cleaning solutions. It has the least power stream.
FIG. 24

NOTE:
Before using the pressure washer to clean patio paving slabs it is advisable to test a small area first,
some paving slabs are manufactured from inferior materials and the use of a pressure washer could
damage the surface.
USING THE DETERGENT FACILITY (Fig. 25)
Fill a suitable container with pressure water detergent. Do not use washing up liquid as it contains salt. We
recommend the use of good quality pressure washer detergent for use with this pressure washer. Most
automobile detergents are a combination of a detergent and a wax solution. The viscosity (thickness) of the
detergent will increase in cold weather. It is recommended that this type of detergent is diluted with water before
filling the container. When using combination wash and wax solutions we recommend that they are diluted before
use. As a general guide we would recommend a dilution rate of 50/50. However a trial and error process would
determine the ideal dilution rate for a particular detergent.
NOTES:
A thick viscous detergent would not flow freely from the detergent tank and the residue would cause a blockage
flow system. After using the detergent facility it should be flushed thoroughly using copious amount of water. To
activate detergent delivery, fit the Black LOW PRESSURE nozzle to the and of the lance. Submerge the and of
the detergent pick up pipe into your container of pressure water detergent. Suction and mixing will occur
automatically as the water flows though the pump.
FIG. 25 FIG. 26
CLEARING A BLOCKAGE (Fig. 26)
If at any time the flow rate stutters or is inconsistent, release the trigger and switch OFF the machine.
Squeeze the trigger to relieve any pressure and check the jet in the end of the lance for any blockage.
If a blockage is suspected use some wire to clean the inside of the nozzle.

FUEL AND FUEL TANK:
Only use unleaded petrol or fuel with an octane number over 86. Using unleaded petrol or fuel will decrease the
possibility of producing carbon deposit and prolong the engines service life. Never use old or polluted petrol or
fuel or a mixture of petrol and engine oil. Make sure the fuel is free of dirt and water.
CAUTION:
Handle fuel with care because it can damage plastic and painted surfaces.Remove the fuel filler cap and check
the fuel level. If the fuel lever is too low, refuel the tank. Remember when adding fuel do not fill over the fuel
filter shoulder.
WARNING:
Petrol is extremely flammable and is explosive under certain conditions. Refuel in a well ventilated area with the
engine stopped. Do not smoke or allow flames and sparks in the area where petrol is stored or where the fuel
tank is refuelled. After refuelling make sure the fuel cap is returned securely.Be careful not to spill fuel when
refuelling. Spilled fuel or fuel vapour may ignite. If any fuel is spilled make sure the area is dry before starting
the engine.
FUEL TANK FILTER (Fig.28):
After every 150 hours of running or every three months the fuel tank filter should be removed and cleaned.
Remove the fuel tank filler cap and the filter, clean the filter thoroughly using environmentally friendly water
based degreasing agent and re-fit.
OIL LEVEL SWITCH:
The engine oil alarm is designed to prevent the operator starting the engine when the oil in the crankcase is
insufficient. Running with insufficient oil will damage the engine. Once the oil level in the crankcase is too
low, the engine oil alarm will stall the engine automatically to avoid damage while the engine switch is still ON.
FIG. 28
AIR FILTER (Fig.29):
After every 100 hours of running or every month, the air filter should be removed and examined for deterioration
and cleaned. Clean the air filter thoroughly using environmentally friendly water based degreasing agent. Allow
to dry fully then replace the air filter. Never run the engine without the air filter fitted.
STORAGE:
If the engine is not to be used or is to be stored for more than one month the following storage procedure should
be carried out.
1. Drain all the fuel from the fuel tank and the carburettor ensure that all the fuel has been removed.
2.Remove the spark plug and pour approximately one tablespoon full of clean engine oil into the spark plug hole.
3.With the ignition turned OFF gently pull on the recoil starter cord several times.
4.Re-fit the spark plug and continue to pull the recoil starter cord until the piston is on the compression stroke
(when resistance is felt) then stop pulling.
5.Store the pressure washer in a dry well ventilated place under a cover to prevent any dust or debris from
accumulating on the pressure washer.
WINTER AND LONG TERM STORAGE:
If the pressure washer is not to be used for more than 3 months or if there is a danger of ice or frost during winter
months the pump unit will require protection to prevent seizing and damage caused by freezing.

MAINTENANCE
EXHAUST CONTROL SYSTEM
With the engine running, carbon monoxide, nitrogen oxide and hydrocarbon are produced, and in certain
conditions nitrogen oxide and hydrocarbon will react together to make smoke while carbon monoxide is toxic,
so exhaust control is very important. The manufacturer decreases exhaust emissions by introducing poor-fuel
carburettors and other devices to solve the problem. To keep the exhaust of your engine within the standard
exhaust emission values, pay attention to the following:
MAINTENANCE
Maintain the engine periodically in accordance with the maintenance schedule. The maintenance schedule is
made out on the basis of normal use in normal conditions. If using under heavy load, dusty or wet conditions
or in high temperature, more frequent maintenance will be necessary.
REPLACEMENT OF PARTS
We recommend that you use parts that are supplied by the manufacturer or equivalent quality parts.
Replacement parts of inferior quality may impair the effectiveness of the exhaust control system.
MODIFYING
Modifying the exhaust control system may make exhaust emissions exceed statutory limits. Illegal
modifications are:
Dismantling or modifying any part of the air inlet or outlet system.
Modifying or removing speed adjustment controls or connections which may result in the engine running
outside its set parameters.
PROBLEMS AFFECTING EXHAUST EMISSIONS
1.Difficulty in starting or stopping.
Erratic idling.
Poor ignition spark or no spark.
5.Ignition too advanced. If you have any of these above problems please contact your dealer.
CAUTION:
Before carrying out any maintenance to the machine release any
pressure and remove the water connection.
WATER SUCTION FILTER CHECKING
Check periodically in order to avoid deposits clogging it.

2.
3.
4.
Giving off black smoke or excessive fuel consumption.
SPARK PLUG MAINTENANCE
After every 50 hours clean the spark plug with a brush. If the insulator on the spark plug is damaged replace
it immediately. Check the spark plug gap with a feeler gauge, the gap should be 0.7 - 0.8mm. If adjustment is
necessary bend the side electrode carefully. Check the spark plug gasket is in good condition or replace with
a new one. Screw in the spark plug to the bottom first by hand and then tighten by using a spark plug wrench.
If a new spark plug is used, twist a 1/2 more turn after impacting the gasket. If using the original one twist
1/8 -1/4 more turn.
CAUTION:
The spark plug eliminator should be serviced at least once every 100 hours of operation so as to keep it in
good condition.
WARNING:
The muffler is very hot during running the engine and for a prolonged period after stopping. Only service after
the engine cools down completely.
Unscrew two nuts and remove the exhaust elbow from the engine body.
Unscrew five screws from the muffler guard and take it out.
Unscrew from the spark plug eliminator and separate from the muffler.
Clean the spark eliminator mesh with a wire brush.
Reinstall the spark eliminator in reverse order of removal.
CAUTION:
Be careful not to damage the spark eliminator. Never use a damaged spark eliminator.
CARBURETTOR IDLING ADJUSTMENT:
Start and pre-heat the engine until it reaches normal working temperature. Obtain standard idling by adjusting
the throttle fixing screw under the engine, Standard idling: 3400 300rpm.

TRANSPORT
Transport with the fuel switch in the off position. Ensure the engine is cooled so as to avoid the risk of
burns or fire.
CAUTION:
Do not tilt the engine to avoid spilling fuel. Spilled fuel or fuel vapour may ignite.
STORAGE
If the engine is not to be used for a long period of time ensure it is stored correctly. Make sure the storage
area is dry and free of dust.
PREPARE FOR STORAGE
Disconnect the spark plug. Put a spoonful of fresh engine oil into the cylinder and rotate the engine to
distribute the oil evenly. Replace the spark plug. Pull the starting rope until you feel resistance and then
keep pulling so as to align the arrow of the starting sleeve with the hole of the starter: This will close both
the inlet and outlet valves to help prevent the engine rusting inside.Cover the engine to keep it free of dust.
REMOVAL FROM STORAGE
Before re-using, service the engine in accordance with the instructions in the following table.
1 Unscrew the drain plug and drain out the fuel in the carburettor:
2 Turn off the engine switch first, disconnect the deposit cup and empty it.
NOTE:
