S Pinch-Kickback can 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 reversal of the chain
force used to cut wood and causes the
sawtomoveintheoppositedirectionofthe
chain rotation. The saw is driven straight
back toward the operator.
S Pull-In can occur when the moving chain
contacts a f oreign object in the wood in the
cut alongthe bottom ofthe guidebar and the
saw chain is suddenly stopped. This sudden
stopping pulls the saw forward and away
from theoperator and couldeasily causethe
operator to lose control of the saw .

structions thatcan causematerial topinch
the top of or otherwise stop the chain.
S Do 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 Obstructions
REDUCE THE CHANCE OF
KICKBACK
S Recognize that kickback can happen.
With a basic understanding of kickback,
you can reduce the element of surprise
which contributes to accidents.
S Neverletthemovingchaincontactanyob-
ject at the tip of the guide bar.
S Keep the working area free from obstruc-
tionssuchas othertrees,branches,rocks,
fences, stumps, etc. Eliminate or avoid
any obstruction thatyour saw chain could
hit while you are cutting. When cutting a
branch, do not let the guide b ar contact
branch or other objects around it.
S Keep your saw chain sharp and properly
tensioned. A loose or dull chain can in-
crease the chance of kickback occurring.
Follow manufacturer’s chain sharpening
andmaintenanceinstructions. Checkten-
sion at regular intervals with the engine
stopped, never with the engine running.
Make sure the bar nuts are securely tight-
ened after tensioning the chain.
S Begin andcontinue cutting atfull speed. If
the chain is moving at a slower speed,
thereis greater chanceof kickback occur-
ring.
S Cut one log at a time.
S Use extreme caution when re-entering a
previous cut.
S Do not attempt cuts starting with the tip of
the bar (plunge cuts).
S Watch for shifting logs or other forces that
could close acut and pinch or fall into chain.
S Use the Reduced--Kickback Guide Bar
and Low--Kickback Chain specified for
your saw.
