Owner’s Manual
Instructions for Set-up, Operation, Maintenance & Storage
HOT WATER/STEAM PRESSURE WASHER 3000 PSI / 4.0 GPM
Portable Outdoor-Use Only
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.
WARNING READ THIS MANUAL
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
CO Poisoning
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.
Skin/Eye Injury
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.
Burns
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.
Slips/FallsNOTE
Spray discharge can cause puddles and slippery surfaces.
Spray-gun kickback can cause operator loss of balance and falls.
Flying Debris
High-pressure spray can cause surface damage and flying debris.
Fire/
Explosion
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.
Chemical Exposure
Cleaning chemical vapors or contact with skin may be hazardous.
Electric shock
Spray contact with electrical sources can cause electric shock.
A summary of important safety information is provided at the end of the manual.
