Preventing Kick-Back
Essentially, TriLink
®
Saw Chain carries two types of chain:
LOW KICK-BACK (SAFETY) and PROFESSIONAL chain.
Low Kick-Back chains are specifically made to reduce the kick-
back energy, however they do not completely eliminate kick-back.
There are two types of kick-back: LINEAR KICK-BACK and
ROTATIONAL KICK-BACK. A clear understanding of both of
these will help in reducing kick-back.
Linear Kick-Back is caused when the saw chain and guide bar
become pinched at the top of the guide bar during the cut. The
pinched chain and bar will cause a strong backward motion (kick-
back) as the chain catches in the pinched cut. The use of a felling
wedge will prevent the wood surface from pinching the guide bar
and allow a smoother, faster cut.
Rotational Kick-Back is caused by the tip of the guide bar and saw
chain catching an object and pushing back in an upwards motion
(kick-back). A proper cut, one where the user does not lead with
the nose, will help prevent rotational kick-back from occurring.
Improperly sharpening or filing of guardlinks will increase the risk
of kick-back.
