GUARD AGAINST KICKBACK Follow all safety rules to help avoid kick- back and other forces which can result in serious injury.

Kickback Path

Avoid Obstructions

Clear The Working Area

WARNING: Avoid kickback which can result in serious injury. Kickback is the backward, upward or sudden for- ward motion of the guide bar occurring when the saw chain near the upper tip of the guide bar contacts any object such as a log or branch, or when the wood closes in and pinches the saw chain in the cut. Contacting a foreign object in the wood can also result in loss of chain saw control.

SRotational Kickback can occur when the moving chain contacts an object at the upper tip of the guide bar. This con- tact can cause the chain to dig into the object, which stops the chain for an instant. The result is a lightning fast,

reverse reaction which kicks the guide bar up and back toward the operator.

SPinch-Kickbackcan occur when the the wood closes in and pinches the moving saw chain in the cut along the top of the guide bar and the saw chain is suddenly stopped. This sudden stopping of the chain results in a rever- sal of the chain force used to cut wood and causes the saw to move in the op- posite direction of the chain rotation.

The saw is driven straight back toward the operator.

S Pull-Incan occur when the moving chain contacts a foreign object in the wood in the cut along the bottom of the guide bar and the saw chain is sud- denly stopped. This sudden stopping pulls the saw forward and away from the operator and could easily cause the operator to lose control of the saw.

REDUCE THE CHANCE OF

KICKBACK

The following precautions should be fol-

lowed to minimize kickback:

4

S Recognize that kickback can happen. With a basic understanding of kickback, you can reduce the element of surprise which contributes to accidents.

S Never let the moving chain contact any object at the tip of the guide bar.

SKeep working area free from obstruc- tions such as other trees, branches, rocks, fences, stumps, etc. Eliminate

or avoid any obstruction that your saw chain could hit while cutting.

SWhen cutting a branch, do not let the

guide bar contact another branch or other objects around it.

S Keep saw chain sharp and properly tensioned. A loose or dull chain can in- crease the chance of kickback. Follow manufacturer’s chain sharpening and maintenance instructions. Check ten- sion at regular intervals, but never with engine running. Make sure bar mount- ing nuts are securely tightened.

S Begin and continue cutting at full speed. If the chain is moving at a slow- er speed, there is greater chance of kickback occurring.

S Use extreme caution when re-enter- ing a cut.

SDo not attempt cuts starting with the tip

of the bar (plunge cuts).

SWatch for shifting logs or other objects that could close a cut and pinch or fall

onto chain.

SUse the specified Reduced-Kickback Guide Bar and Low Kickback Chain.

Avoid Pinch-Kickback:

SBe extremely aware of situations or ob- structions that can cause material to pinch the top of or otherwise stop the

chain.

SDo not cut more than one log at a time. S Do not twist the saw as the bar is with- drawn from an undercut when bucking.

Avoid Pull-In:

S Always begin cutting with the saw at full speed and the saw housing against wood.

SUse wedges made of plastic or wood. Never use metal to hold the cut open.
