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.
