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.
