KICKBACK SAFETY PRECAUTIONS FOR CHAIN SAW USERS
WARNING
Kickback may occur when the nose or tip of the guide bar touches an
object. or when the wood closes in and pinches the saw chain in the
cut. Tip contact in some cases may cause a lightning fast reverse
reaction.kicking the guide bar up and back towards the
operator .Pinching the saw chain along the top of the guide bar may
push the guide bar rapidly back towards the operator Either of these
reactions may cause you to lose control of the saw. which could result
in serious personal injury.
Do not rely exclusively on the safety devices built into your saw. As a
chain saw user you should take several steps to keep cutting jobs free
from accident or injury.
(1) With a basic understanding of kickback you can reduce or
eliminate the element of surprise. Sudden surprise contributes to
accidents.
(2) Keep a good grip on the saw with both hands. the right hand on the
rear handle, and the left hand on the front handle. when the engine is
running, Use a firm grip with thumbs and fingers encircling the chain
saw handles. A firm grip will help you reduce kick-back and maintain
control of the saw.
(3) Make certain that the area in which you are acting is free from
obstructions. Do not let the nose of the guide bar contact a log. branch,
or any other obstructions which could be hit while you are operating
the saw.
(4) Cut at high engine speeds.
(5) Do not overreach or cut above shoulder height.
(6) Follow the manufacturers sharpening and maintenance
instructions for the saw chain.
(7) Only use replacement bars and chains specified by the
manufacturer or the equivalent.
