OPERATION
Moving parts can amputate fingers or cause severe injuries. Keep hands, clothing and loose objects
away from all openings. Always stop engine, disconnect spark plug, and make sure all moving parts
have come to a complete stop before removing obstructions, clearing debris, or servicing unit.
Engine exhaust IS HOT, and contains Carbon Monoxide (CO), a poison gas. Breathing CO can cause
unconsciousness, serious injury, or death. Exhaust can cause serious burns. ALWAYS position unit
so that exhaust is directed away from your face and body.
Operation of this equipment may create sparks that can start fires. This unit is equipped with a spark
arrestor to prevent discharge of hot particles from the engine. Metal cutters can also create sparks if
the cutter strikes rocks, metal, or other hard objects. Contact local fire authorities for laws or
regulations regarding fire prevention requirements.
