Electric Hot Water/Steam Pressure Washer
Instructions for Set-up, Operation, Maintenance & Storage
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 an electric motor and the water is heated by a diesel, kerosene/fuel-oil fired, down draft burner.
WARNING: SPECIAL HAZARDS
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 and burner, as well as hot exhaust from the burner can
cause burns.
Slips/Falls: 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: Burner sparking can ignite fuel or other flammable liquids or vapors in the vicinity. Hot exhaust from 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.
Electrocution: Improper connection of the equipment or grounding conductor can result in a risk of electrocution.
CO Poisoning: Exhaust from burner contains carbon monoxide, a poisonous gas that can cause carbon monoxide poisoning
and possible death if inhaled.
Equipment Protection Quick Facts
Inspect Upon Delivery: STOP! Closely inspect to make sure no components are missing or damaged. For missing
