• Always operate pressure washer in a well ventilated area free of
flammable vapors, combustible dust, gases or other combustible
materials.
• Do not store the pressure washer near an open flame or any
equipment such as a stove, furnace, water heater, etc., which utilizes
a pilot light or sparking device.
• Do not use this pressure washer to spray flammable material!
• Do not smoke while filling burner fuel tank.
• Never fill the fuel tanks while the pressure washer is running or hot.
Allow to cool two minutes before refueling.
• Always refuel slowly to avoid the possibility of spilled fuel which may
cause a risk of fire.
• Do not refuel indoors or in a poorly ventilated area.
• Engine Fuel Tank: Refuel with gasoline only. Do not use diesel or fuel
oil.
• Burner Fuel Tank (Black): When refueling the Burner Fuel Tank, use
No. 1 or No. 2 fuel oil/diesel or kerosene. Do not use gasoline.
• Do not operate the unit if diesel fuel is spilled. Wipe the pressure
washer clean and move it away from the spill. Avoid creating any
ignition until the diesel fuel has evaporated.
• A spark arrester must be added to the muffler of this engine if it is
to be used on any forest covered, brush covered or grass covered
unimproved land. The arrester must be maintained in effective working

WARNING
Serious injury or death may occur from inhaling engine/
burner exhaust or dangerous vapors. The engine
exhaust from this product contains chemicals known to
the State of California to cause cancer, birth defects, or
other reproductive harm.
• Never operate this pressure washer in an enclosed area. Always make
certain there is adequate ventilation (fresh outside air) for breathing
and combustion. This will prevent the buildup of dangerous carbon
monoxide gases. Beware of poorly ventilated areas, or areas with
exhaust fans which can cause poor air exchange.
• Follow all safety instructions provided with the materials you are
spraying. Use of a respirator may be required when working with
some materials. Do not use this pressure washer to dispense
hazardous detergents.

• SEEK EMERGENCY MEDICAL CARE if the spray appears to have
penetrated the skin! DO NOT TREAT AS A SIMPLE CUT!!
• High pressure hoses and fuel lines should be inspected daily for signs
of wear. If evidence of failure exists, promptly replace all suspect
hoses and fuel lines to prevent the possibility of injury from the high
pressure spray. If a hose or fitting is leaking, NEVER PLACE YOUR
HAND DIRECTLY ON THE LEAK.
• NEVER operate the gun with the trigger wired in the open position.
To prevent accidental discharge, the trigger gun should be securely
locked when not in use.
