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 foreign object in the wood in the
cut a long th ebottom o fthe guid ebar andthe
saw chain i s suddenly stopped. This sudden
stopping pulls the saw forward and away
from th eoperatorand could easily causethe
operator to lose control of the saw .

structions thatcancausematerialtopinch

REDUCE THE CHA NCE 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-
tionssuchasothertrees,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 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 chain brake nuts are se-
curelytightenedaftertensioningthechain.
S Begin and continue cutting at full speed. If
the chain is m oving at aslower speed, there
is greater chance of kickback occurring.
S Cut one log at a time.
S Use extreme caution when re-entering a
previous cut.
S Do notattempt cuts starting with the tipof
the bar (plunge cuts).
S Watch forshifting logs orother forces t hat
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.
