S Pinch-Kickback can occur when the the
wood closes in and pinches the m oving
saw chain in the c ut 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 u sed to cut wood and causes the
sawtomoveintheop positedirectionofthe
chain rotation. The saw is driven straight
back toward the operator.

contacts a foreign ob ject in the woo d in the
cut alongthebottom ofthe guidebar andthe
saw chain is suddenly stopped. This sudden
stopping pulls the saw forward and away
from theoperator andcouldeasily causethe
operator to lose control of the saw .

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 a t the tip of the guide bar.
S Keep the working area free from obstruc-
tionssuchasothertrees,branches,rocks,
fences, stumps, etc. Eliminate or avoid
any obstruction that your saw chain could
hit while you are cutting. When cutting a
branch, do not let the guide bar 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 aresecurely tight-
ened after tensioning the chain.
S Begin andcontinuecuttingat fullspeed. If
the chain is moving at a slower speed,
thereis greater chance o fkickbackoccur-
ring.
S Cut one log at a time.
S Use extreme caution when re-entering a
previous cut.
S Do not a ttempt cuts starting with the tip of
the bar (plunge cuts).
S Watch for shifting logs or other forces that
could close a cut and pinch or fall into
chain.
S Use the Reduced--Kickback Guide Bar
and Low--Kickback Chain specified for
your saw.
