5.1.7. To start the engine give a steady pull on the starting handle. The engine will be a little easier to start if the trigger is pressed during
starting. This must be done by a second person who can control the initial kickback as the water is expelled.
5.1.8. As the engine warms up move the choke lever left into the ‘run’ position.
5.2. NOZZLE SPRAY ADJUSTING g.4.
5.2.1. Adjust the nozzle pressure and spray pattern as described in section 4.3.
WARNING!
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.
5.3. SHUT DOWN PROCEDURE
5.3.1. Turn the engine switch to the OFF position.
5.3.2. In an emergency turn the engine switch to the OFF position.
WARNING! De-pressurise after cleaning is completed, turn o the water supply and pull the trigger to de-pressurise the unit. Failure
to do so might result in personal injury due to discharge of high-pressure water.
5.4. CLEANING WITH DETERGENTS
IMPORTANT This pressure washer is intended for use with special pressure washer detergents only. DO NOT use powdered soaps,
as this will clog the injection system. Follow the detergent manufacturer’s directions.
IMPORTANT Working with a detergent ensures quick soaking of the dirt, and allows the high-pressure water to penetrate and remove
the dirt more effectively. Always spray detergent on a dry surface, DO NOT pre soak the area. Soaking the surface dilutes the
detergent and reduces its cleaning ability.
WARNING! Damage may occur to surfaces if chemicals (detergents) are allowed to dry on them. Wash and rinse a small section at a
time. Avoid working on hot surfaces or under direct sunlight.
5.4.1. When applying detergents, always operate the unit at low water pressure position (fig.2). This provides a gentle application of the
detergent, with the water pressure equivalent to a garden hose. Always test the detergent in a concealed area before use.
5.4.2. The liquid detergent will be mixed with water automatically, and discharged through the detergent nozzle at a low pressure.
5.4.3. Allow detergent to remain on the surface for a short time before rinsing. DO NOT allow detergent to dry on the surface.
5.5. SHUTTING DOWN AND CLEANING UP
5.5.1. Skip step 5.5.2 if you are not using detergent.
5.5.2. After cleaning with detergent, fill the detergent tank with clean water. Spray water at a low pressure for one minute, so that all detergent
is flushed out of the system.
5.5.3. Stop the engine (→ Section 5.3 Shut Down Procedure).
5.5.4. Turn off the water supply and disconnect the water supply from the water inlet.
5.5.5. Point spray gun in safe direction, push trigger lock, and squeeze spray gun trigger to relieve retained high water pressure. Engage the
trigger safety lock (fig.3) on the spray gun.
5.5.6. Disconnect the garden hose from the pump.
5.5.7. Disconnect the pressure hose from the pump and pressure gun for storage. For long-term storage instructions, see section 7.8.
5.5.8. Rewind the pressure hose and attach it to the hose hook.
5.5.9. Disconnect the gun and wand, then insert them into the upper gun holder.
5.5.10. Fold the handle and store.
NOTE: After turning off the machine, wait for 20 minutes to prevent plastic parts from being burned by muffler, then fold the handle.
5.6. ADDING/CHECKING OIL
IMPORTANT Oil has been drained for shipping. Failure to fill engine with oil before starting engine will result in permanent damage and
will void engine warranty.

antifreeze is expelled from the pump.
6.2. CLEANING WATER INLET FILTER
WARNING! DO NOT operate this pressure washer without the water inlet lter in place, as deposits could build up internally and
aect the functioning of the unit.
6.2.1. This pressure washer is equipped with a water inlet lter.
6.2.2. The water inlet lter must be kept clean at all times, otherwise it can restrict the water ow to the pump unit and damage it.
6.2.3. Remove the quick-connect coupler from the water inlet, then carefully remove and clean the water inlet lter.
7. MAINTENANCE - ENGINE
7.1. 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.
7.2. CHECKING THE OIL LEVEL. Ensure the unit is on a level surface.
7.2.1. Unscrew the dipstick (fig.5) 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.
7.3. DRAINING ENGINE OIL
7.3.1. The engine oil should be replaced after the first 20 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.1.12).
2. Place an oil container underneath the opening at the base of the filler tube.
3. Remove the hex screw plug from the oil drain (fig.5) and drain the oil into the container.
4. Once the oil has been completely drained, replace the hex screw (fig.5) and oil tank dipstick.
7.4. CHECKING AIR FILTER
IMPORTANT: Clean air filter (fig.1.8) element after every 50 hours of use (every 10 hours under dusty conditions).
7.4.1. To access the air filter element rotate cover (fig.1.8) anti-clockwise and remove the foam filter from the air intake base moulding.
7.4.2. 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, locate and replace cover.
7.4.3. The foam element should be replaced after every 300 hours of service.
7.5. INSPECTING, REPLACING OR CLEANING THE SPARK PLUG
NOTE: The spark plug should be checked after every 100 hours of operation or every six months.
7.5.1. To replace or clean the spark plug:
1. Disconnect the spark plug wire by pulling it off the spark plug.
2. Using provided spark plug wrench, remove the spark plug by turning it counter-clockwise. If there is a carbon sediment build-up,
remove it. If there is too much carbon sediment, replace the spark plug.
3. Check the gap with a wire gauge. If necessary, reset the gap to 0.7-0.8 mm. Install and tighten the spark plug to the recommended
torque – 180 lb/in (20 Nm).
4. Reinstall the spark plug wire and protection cage in reverse order.

PWM1300.V2 Issue 2 (2) 07/12/20
NOTE: In some areas, local law requires using a resistor spark plug to
suppress ignition signals. If this engine was originally equipped with a
resistor spark plug, use the same type for replacement.
7.6. CLEANING THE CARBURETTOR
7.6.1. To clean the carburettor (fig.8):
1. Unscrew the bolt on the bottom of carburettor.
2. Push the float up four to five times, then clean sediment cup with fuel.
NOTE: Ensure you replace the O ring when putting the sediment cup back.
7.7. WINTER AND LONG TERM PUMP STORAGE
7.7.1. STEP 1: ENGINE STORAGE. If the unit is not to be used for more than
one month the following procedure should be followed.
1. Top-up engine oil to maximum.
2. Drain petrol from the fuel tank, fuel line, fuel tap and carburettor.
3. 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.
7.7.2. STEP 2: PROTECT FUEL SYSTEM
WARNING! Petrol is extremely ammable and potentially explosive. DO NOT perform maintenance on petrol associated components
where there is any source of ignition present such as cigarettes, sparks, naked ame or hot surfaces.
FUEL ADDITIVE:
Fuel can become stale when stored for over 30 days. Stale fuel causes acid and gum deposits to form in the fuel system or on essential
carburettor parts. Please use fuel stabilizer to keep fuel fresh. Run the engine for 2 minutes to circulate the stabilizer throughout the fuel
system before storage.
DRAIN FUEL
If fuel in the engine has not been treated with a fuel stabilizer, it must be drained into an approved container. Run the engine until it
stops from lack of fuel. Remove the hex screw from the carburettor (fig.8) then drain the fuel from the tank, carburettor, and tube. Screw
the carburettor drain hex screw back once the fuel has been completely drained.
7.7.3. STEP 3: CHANGE OIL (See sections 7.1 - 7.4)
7.7.4. While engine is still warm, drain oil from crankcase. Remove the hex screw from the crankcase (fig.5). Drain the oil to a container. Refill
with recommended grade oil (SAE 10W-30).
IMPORTANT:
• If the pressure washer is to be stored with fuel in the fuel tank and carburettor, it is important to reduce the hazard of fuel vapour ignition.
• Select a well-ventilated storage area away from any appliance that operates with a flame, such as a furnace, water heater, or clothes
dryer. Also avoid any area with a spark-producing electric motor, or where power tools are operated.
• If possible, avoid storage areas with high humidity, this will promote rust and corrosion.
• Place the pressure washer on a level surface. Tilting can cause fuel or oil leakage.
