WARNING
Rapid retraction of starter cord (kickback) will pull hand and arm toward
engine faster than you can let go.
Broken bones, fractures, bruises or sprains could result.
When starting engine, pull the starter cord slowly until resistance is felt and then pull
•
rapidly to avoid kickback.
Remove all external equipment/engine loads before starting engine.
•
Direct-coupled equipment components such as, but not limited to, blades, impellers,
•
pulleys, sprockets, etc., must be securely attached.
WARNING
Rotating parts can contact or entangle hands, feet, hair, clothing, or
accessories.
Traumatic amputation or severe laceration can result.
Operate equipment with guards in place.
•
Keep hands and feet away from rotating parts.
•
Tie up long hair and remove jewelry.
•
Do not wear loose-fitting clothing, dangling drawstrings or items that could become
•
caught.
WARNING
Running engines produce heat. Engine parts, especially muffler, become
extremely hot.
Severe thermal burns can occur on contact.
Combustible debris, such as leaves, grass, brush, etc. can catch fire.
Allow muffler, engine cylinder and fins to cool before touching.
•
Remove accumulated debris from muffler area and cylinder area.
•
Install and maintain in working order a spark arrester before using equipment on
•
forest-covered, grass-covered, brush-covered unimproved land. The state of
California requires this (Section 4442 of the California Public Resources Code).
Other states may have similar laws. Federal laws apply on federal land.
