ADJUSTING THE SPRAY PATTERN (Fig.24)
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 minimal area of cleaning. This nozzle should only be used
on a 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
FIG. 24
intense cleaning of small areas. This nozzle should only be used on areas that
can withstand the high pressure from this nozzle.
25°nozzle-green. This nozzle delivers a 25 degree spray pattern for intense
cleaning of larger areas. This nozzle should only be used on areas that can
withstand the 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
- 14 -
solutions. It has a minor power stream.
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
Fill a suitable container with pressure water detergent. Do not use washing
up liquid as it contains salt. We recommend using 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. This
type of detergent is recommended to be 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 through the pump.
CLEARING A BLOCKAGE (Fig. 25)
FIG. 25
- 15 -
If the flow rate stutters or is inconsistent at any time, 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.

PRE-OPERATION INSPECTION
CAUTION: Engine oil is a key factor in deciding the engine s performance. Do not
use engine oil with additives or 2-stroke gasoline engine oil, as they do not have
enough lubricating properties, which may shorten the engine s service life.
1. Check the engine is on level ground.
2.0.6L 15W-30 is recommended for general all-temperature use. (FIG. 26)
3.Remove the dipstick and clean it.
4.Reinsert the dipstick into the oil filler without screwing it in and check the oil level.
5.If the oil level is too low add the required engine oil to the oil filler mark.
6.Replace the dipstick securely.
CAUTION: Running with insufficient engine oil may damage the engine severely.
FIG. 26
FUEL AND FUEL TANK:
Only use unleaded petrol or fuel with an octane number over 86. Using unleaded
gasoline or fuel will decrease the possibility of producing carbon deposit and
- 18 -
prolong the engine's 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, do not fill over the fuel filter shoulder when adding
fuel.
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
refueling; make sure the fuel cap is returned securely.Be careful not to spill fuel
when refuelling. Spilled fuel or fuel vapor may ignite. If any fuel is spilled,ensure
the area is dry before starting the engine.
FUEL TANK FILTER (Fig.27):
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 from 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. 27 FIG. 28
- 19 -
AIR FILTER (Fig28):
After every 100 hours of running or every month, the air filter should be removed,
examined for deterioration, and deaned. Clean the air filter thoroughly using an
environmentally friendly water-based degreasing agent Allow to dry thoroughly；
then replace the air filter. Only run the engine with 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 carburetor 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 carburetors and other devices to solve the problem. To keep the exhaust
- 20 -
of your engine within the standard exhaust emission values, pay attention to the
following:
MAINTENANCE
Maintain the engine periodically following the maintenance schedule. The
maintenance schedule is made out on the basis of normal use in normal conditions.
For example, more frequent maintenance will be necessary if used under heavy
loads, dusty or wet conditions, or in high temperatures.
REPLACEMENT OF PARTS
We recommend you use parts 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:
1.Dismantling or modifying any part of the air inlet or outlet system.
2.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.
2.Erratic idling.
3.Giving off black smoke or excessive fuel consumption.
4.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
- 21 -
Check periodically in order to avoid deposits clogging it.
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 it
with a new one. Screw the spark plug to the bottom by hand and then tighten it
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 while 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 the spark plug eliminator and separate 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.
- 22 -
TRANSPORT
Transport with the fuel switch in the off position. Ensure the engine is cooled to
avoid the risk of burns or fire.
CAUTION:
Do not tilt the engine to avoid spilling fuel. Spilled fuel or fuel vapor 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 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 from rusting inside.Cover the engine to
