WARNING: SPECIAL HAZARDS
CO Poisoning: Exhaust from engine 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.

amputation. Such an injection injury can result in blood poisoning and/or severe tissue damage.
Flying Debris: High-pressure spray can cause flying debris and possible surface damage.
Electric shock: Operating equipment in wet conditions or near water can cause electric shock.
