OPERATION
warning
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 com-
plete stop before removing obstructions, clearing debris, or servicing unit.
warning
Engine exhaust IS HOT, and contains Carbon Monoxide (CO), a poison gas. Breathing CO can cause uncon-
sciousness, serious injury, or death. Exhaust can cause serious burns. ALWAYS position unit so that exhaust is
directed away from your face and body.
warning
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 blade use also can create sparks if the blade strikes
rocks, metal, or other hard objects. Contact local fire authorities for laws or regulations regarding fire prevention
requirements.
warning
The ignition components of this machine generate an electromagnetic field during operation which may interfere
with some pacemakers. To reduce the risk of serious or fatal injury, persons with pacemakers should consult
with their physician and the pacemaker manufacturer before operating this machine. In the absence of such
information, ECHO does not recommend the use of ECHO products by anyone who has a pacemaker.
