If you start to feel sick, dizzy, or weak after the pressure washer has
been running, move to fresh air RIGHT AWAY. See a doctor. You could
have carbon monoxide poisoning.
Pressure washers vibrate in normal use. During and after the use of the
pressure washer, inspect the pressure washer as well as hoses connected
to it for damage resulting from vibration. Have damaged items repaired
or replaced as necessary. Do not use hoses that show signs of damage
such as broken or cracked insulation or damaged connectors.

3. PRE-OPERATION CHECK
These quick checks should be done each time the pressure washer is started to
ensure you get the most out of your pressure washer.
Set the pressure washer on a level surface and the power switch to OFF.
WARNING!
Exhaust gas contains poisonous carbon monoxide. Never run the
pressure washer in an enclosed area. Be sure to provide adequate
ventilation. Operate the pressure washer on a level surface. If the
pressure washer is tilted, fuel spillage may result. Keep away from
rotating parts while the pressure washer is running. The pressure
washer is air-cooled and may be damaged if ventilation is inadequate.
3.1 PREPARE THE AIR FILTER
Check the air filter before your first use. Check the maintenance schedule for a
complete cleaning guide.
Loosen the knob and remove the air filter cover. Remove the air filter element and
inspect for cleanliness.
1. Loosen the nut and remove the air filter cover. Remove the air filter housing
and elements and inspect for cleanliness.
2. Gently shake the paper filter or blow with air to remove the dust and
debris.

3. Clean the foam air filter with soap and water or solvent and let dry.
4. Soak the foam filter in clean engine oil.
5. Gently squeeze and then pat out all excess oil and reinstall. If excess oil
remains in the foam filter it can seep through to the paper filter and
damage it.
6. Replace either filter if it is damaged.E
Note
Running the engine without the air filter will quickly degrade the engine
Always inspect air filter before using the pressure washer. Check and
clean the air filter according to the maintenance schedule.
3.2 ADD ENGINE OIL
1. Ensure the pressure washer is on a level surface.
2. Unscrew one oil dipstick and clean the dipstick.
3. Check the oil level by reinserting the oil dipstick without screwing it back in.
Remove the dipstick and examine the oil level. If the level is at or below the
minimum oil level marked on the dipstick, refill to the maximum oil level
mark using a funnel.
4. Reinsert the dipstick and tighten securely.
Note
Max. oil capacity: 600mL
SAE 10W-30 is recommended for general use.
Do not tilt the pressure washer when adding engine oil. This could result
in overfilling and damage to the engine.
Using non-detergent or 2-stroke oil could shorten the engine’s working
life.

3.3 ADD FUEL
WARNING!
Gasoline is highly flammable and explosive under certain conditions.
Refuel in a well-ventilated area with the engine stopped. Do not
smoke or allow open flames or sparks in the area where the pressure
washer is being refueled or where gasoline is stored. Do not overfill
the tank. Be careful not to spill fuel when refueling. Wipe up any
spilled gasoline and let the area dry before starting the engine.
Gasoline substitutes such as gasohol are not recommended. They
may be harmful to the fuel system components.
1. Check the fuel level by removing the fuel tank cap to visually check the
level.
2. Add fuel until the level reaches 1.5" below the top of the neck. Tighten the
fuel cap securely after refilling.
Note
Only use unleaded gasoline (Pump Octane 87 or higher).
Never use stale or contaminated gasoline, or an oil/gasoline mixture.
Avoid getting dirt or water into the fuel tank.
Do not use a mixture of gasoline containing methanol. This will cause
serious damage to the engine.
Use of gasoline with an ethanol content greater than 10% can damage
the engine and fuel system and will void the manufacturer’s warranty.

3.4 CHECK THE COLD WATER SUPPLY
Check local regulations of your municipal water company to check if
a backflow prevention device is required when hooking up to drinking
water. This ensures no feedback of chemicals will return to the water
supply. Use a water filter to avoid potential damage from dirt in the
water supply.
Garden hose must be at least 1/2" interior diameter.
Flow rate of water must not fall below 5.0 GPM. Flow rate can be
determined by running hose into an empty 5 gallon pail for 1 minute.
The water supply temperature must not exceed 40°C/104°F.
Never use the pressure washer to draw in water contaminated with
solvents eg. paint thinners, gasoline, oil etc.
Always prevent debris from being drawn into the unit by using a clean
water source and additional water filter.
DO NOT operate pressure washer without the water supply turned on.
