GENERAL SAFETY INSTRUCTIONS
SAFETY WHILE REFUELLING
1. FUEL OUTDOORS. Fill fuel tank outdoors – never indoors. Fuel vapours can
ignite if they collect inside an enclosure. Explosion can result.
2. USE APPROVED CONTAINER. Never pump fuel directly into fuel tank at
service station. Static charge can build and ignite fuel. Use an approved fuel
container to transfer fuel to the engine.
3. RUNNING / HOT ENGINE. A running engine is hot enough to ignite fuel. Never
add fuel or remove fuel cap if engine is running or still hot. Stop the engine and
allow it to cool, at least five minutes before adding fuel.
4. HEAT / FLAMES / SPARKS. Stay away from sources of heat, flame, or sparks
while adding fuel. Fuel vapour is easily ignited.
5. DO NOT OVERFILL THE FUEL TANK. Only fill with fuel to the top of the fuel
strainer. The fuel cap has a small ventilation hole in it to prevent fuel lock. If The
fuel tank is over filled it may lead to a spillage from the fuel cap when the engine
is started.
6. REPLACE CAP. Replace fuel cap securely before starting engine.
7. SPILLS. Clean up fuel spills immediately. Move pressure washer away from
spilled fuel on the ground. Wipe fuel off engine and wait 5 minutes for excess
fuel to evaporate before starting engine. Fuel soaked rags should be disposed
of properly.
8. FUEL ON SKIN / CLOTHES. Fuel may irritate skin and is also a fire hazard.
If fuel is spilled on your skin or clothes, change clothes and wash skin
immediately.
9. FUEL STORAGE. Store fuel in a cool, dry place in an approved, tightly sealed
container.
10. MOVE AWAY FROM FUELLING SITE BEFORE STARTING TOOL. Don’t
smoke while refuelling.
SAFETY IN OPERATION
1. DO NOT USE IN CONFINED SPACES OR AREAS WITH POOR
VENTILATION.
When running, the engine gives OFF carbon monoxide gas which is toxic.
Carbon monoxide poisoning can kill. If the operator or people nearby feel sick,
dizzy, or weak while the pressure washer is running, turn OFF the pressure
washer if possible, and immediately move everybody away into the fresh air.
Seek medical attention!
2. INSPECT AND PREPARE PRESSURE WASHER BEFORE EACH USE AS
DIRECTED IN THIS MANUAL.
3. DO NOT USE FOR SPRAYING FLAMMABLE OR CORROSIVE CHEMICALS
IN THE PRESSURE WASHER. This can lead to dangerous situations and/or
damage to the pressure washer.

10
GENERAL SAFETY INSTRUCTIONS
4. DO NOT RUN PRESSURE WASHER WHILE UNATTENDED. The operation of
the pressure washer should always be monitored to ensure safe operation.
5. FOLLOW INSTRUCTIONS FOR SAFETY WHEN REFUELING THE ENGINE.
Fuel is ammable and can explode. Always use caution when handling fuel.
6. DO NOT START PRESSURE WASHER UNTIL READY TO USE. This will
avoid intentional release of water.
7. IF YOU ARE STARTING A WARM ENGINE, STAY CLEAR OF MUFFLER. It
may still be hot enough to burn.
8. NEVER OPERATE OR LET ANYONE ELSE OPERATE THE PRESSURE
WASHER WHILE UNDER THE INFLUENCE OF ALCOHOL, DRUGS OR
MEDICATION.
9. WHILE ADJUSTING OR REPAIRING. Turn OFF engine and remove spark plug
cap before cleaning, inspecting or servicing the pressure washer.
SAFETY AFTER USE
1. LET ENGINE COOL BEFORE STORING. Let the engine cool for at least ten
minutes before storing. A hot engine can be a re hazard.
2. STORE IN A WELL VENTILATED PLACE WHEN NOT IN USE. Select a
location away from sources of heat, open ames, sparks or pilot lights –
such as water heaters, space heaters, furnaces, clothes dryers or other gas
appliances. Even if the fuel tank is empty, residual fuel vapours could ignite.
3. STORE EXTRA FUEL IN A COOL, WELL VENTILATED, DRY PLACE IN AN
APPROVED, TIGHTLY SEALED CONTAINER. Fuel vapours can ignite if they
collect inside an enclosure.
4. PERFORM PERIODIC MAINTENANCE AS DIRECTED IN THIS MANUAL TO
KEEP THE PRESSURE WASHER IN SAFE WORKING CONDITION.
WARNING! Do not lift by the pressure washer by yourself. Lifting the
pressure washer by yourself may cause injuries.
SPECIAL WARNINGS FOR PRESSURE WASHERS.
1.HIGH PRESSURE JETS CAN BE DANGEROUS IF SUBJECT TO MISUSE.
The jet must not be directed at persons, live electrical equipment or the
pressure washer itself.
2. ALWAYS ENGAGE THE TRIGGER LOCK WHEN NOT ACTUALLY
SPRAYING. This will reduce the risk of unintended spraying.
3. KEEP OPERATING AREA CLEAR OF ALL PERSONS. Do not use the
pressure washer within range of persons.

17
OPERATION
Oil level check
Check method:
1) Remove the dipstick and clean it.
2) Reinsert the dipstick into the oil lling hole without screwing it, and check oil level
3) If the oil level is too low, add the recommended engine oil up to the oil lling neck.
4) Reinstall the dipstick.
5) Lubrication oil capacity: 210-S 0.5L
NOTICE
Run with insufcient engine oil may damage the gasoline engine severely and that is not
within valid warranty.
2. AIT CLEANER
Dismantle the air cleaner cover and check its element to make sure it clean and complete.
NOTICE
Never run the engine without an air cleaner, or severe wear of the engine may be resulted in. That
is not within the valid warranty.
3. FUEL RECOMMENDATION
1) Remove the fuel tank cap and check fuel level.
2) If the level is too low, refuel the tank. Remember adding fuel not over the fuel ller shoulder.
WARNING
1) Gasoline is extremely ammable and is explosive under certain conditions.
2) Refueling in a Well-ventilation are with the engine stopped. Do not smoke and do not allow ames or
sparks in the area where ga1oline is stored or where the fuel tank is refueled.
3) Do not overll fuel tank (there should be no fuel in the lling neck). After refueling, make sure the fuel tank
cap is set back securely.
4) Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may ignite. If any fuel is spilled, make

APPLICATION
ENGINE OIL ALARM
The engine oil alarm is designed to function when the engine oil in the Crankcase is insufcient. Lack of
engine oil may damage the engine. Once oil level in the crankcase is too low, the engine oil alarm will stall
the engine automatically to make it free of damage while the engine switch is still at “ON”.
NOTE: If the recoil starter is hard to pull, squeeze the spray gun trigger to relieve internal pump pressure.
Stopping:
1. Release the trigger, let the engine run at idle speed for two minutes.
2. Turn the engine switch off to OFF position.
3. Squeeze trigger on the spray gun to relieve pressure in the hose.
Attention!
Risk of machine damage!
Never operate the machine without water inlet as dry running may damage the pump. Use a water
lter if the inlet water is contaminated.
Risk of fatal injury!
Use special care when cleaning tyres. Vehicle tyres/tyre valves may become damaged or burst when
handled improperly. First signs of damage included discolorations on the tyre. Damaged vehicle tyres/tyre
valves pose a life-threatening risk. Keep the jet at a distance of at least 30 cm!
Risk of fatal injury!
The high-pressure jet may be dangerous when handled improperly. The jet should not be directed towards
living beings (persons, animals), live equipment or the machine itself.
High pressure working.
Hold the hand-held spray gun and the jet tube rmly with both hands.
Change the spray tip as per the recommendation above if necessary. Before changing spray tip, switch the
