This pressure washer produces both cold and hot water high-pressure spray as well as wet steam. Cleaning
chemicals may be incorporated into the spray if desired. The pressure pump for this equipment is powered
by a gasoline internal combustion engine and the water is heated by a diesel, kerosene/fuel-oil fired, down
draft burner.
READ and UNDERSTAND this Owner's Manual and the Engine Owner's Manual completely
before attempting to set up and use the pressure washer! Failure to properly set up, operate, and
maintain this pressure washer could result in serious injury or death to operator or bystanders.

WARNING – SPECIAL HAZARDS
•
Exhaust from both the engine and burner contains carbon monoxide, a
poisonous gas that can cause carbon monoxide poisoning and possible death
if inhaled. ONLY run pressure washer OUTDOORS and at least 20 feet from
the home, away from windows, vents and air intakes, to allow proper
ventilation. If you start to feel sick, dizzy, or weak while using the pressure
washer, shut off the engine and get to fresh air RIGHT AWAY.
•
High-pressure spray can cause serious skin or eye injury, including injection
injury if fluid pierces the skin. Injection injury can result in blood poisoning
and/or severe tissue damage.
•
Hot spray can scald and burn skin.
•
Hot surfaces of wand, engine and burner, as well as hot exhaust from
both the engine and burner can cause burns.
•
Spray discharge can cause puddles and slippery surfaces.
•
Spray-gun kickback can cause operator loss of balance and falls.
•
High-pressure spray can cause surface damage and flying debris.
•
Engine and burner sparking can ignite fuel or other flammable liquids
or vapors in the vicinity.
•
Hot exhaust from engine and burner can ignite combustible materials.
•
Cleaning chemical vapors or contact with skin may be hazardous.
•
Spray contact with electrical sources can cause electric shock.

Operation • It mixes the cleaning chemical into a low-pressure spray. Cleaning chemicals applied under low pressure adhere better to the surface being cleaned, allowing the formula time to react and remove dirt more effectively. Note: An external chemical injector pump is not recommended for use with this pressure washer, and if used would obviously alter the 15 to 1 dilution ratio. - Page 25 Operation Instruct all operators. The pressure washer’s owner must instruct all operators and potential renters in safe set-up and operation. Do not allow anyone to operate the pressure washer who has not read the Owner’s Manual and been instructed on its safe use.
