KICKBACK SAFETY PRECAUTIONS FOR CHAIN SAW USERS
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, in the
same way as a conventional chain-saw. 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 kickback and maintain control of the saw.
Don’t let go.
(3) Make certain that the area in which you’re cutting is free
from obstructions. Do not let the nose of the guide bar
contact a log, branch, or any other obstruction 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 manufacturers sharpening and maintenance
instructions for saw chain.
(7) Only use replacement bars and chains specified by the
manufacturer or the equivalent.
