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
saw tomove inthe opposite direction ofthe
chain rotation. The saw is driven straight
back toward the operator.
S Pu ll-In can occur when the moving chain
contacts a foreign object in the wo od in th e
cut along the bottom of the guide bar a nd the
saw chain is suddenly 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 .
Avoid Pinch--Kickback:
S Be extremely aware of situations or ob-
structions that can cause material to pinch
the t op of or other wise stop t he 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 under cut w hen bucking.
Avoid Pull--In:
S Always begin cutting with the engineat full
speed and the saw housing against wood.
S Use wedges made of plastic or wood.
Never use metal to hold the cut open.

Clear The Working Area
Avoid Obstructions
REDUCE THE CHANCE OF
KICKBACK
S Recognize that kickback can happen.
With a basic understanding of kickback,
you can reduce the elem ent of surprise
which contributes to accidents.
S Never let themoving chain c ontact anyob-
ject at the tip of the guide bar.
S Keep the w orking area free f rom obstruc-
tions suchas other t rees, 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 t he chance of kickback occurring.
Follow manufacturer’s chain sharpening
and maintenance instructions. Check ten-
sion at regular intervals with the engine
stopped, never with the engine running.
Make sure the bar nuts are securely t ight-
ened aft er tensioning t he chain.
S Begin and continue cutting at full speed. If
the chain is moving at a slower speed,
there is greater chance of 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 f or shifting logs or other forces that
could close a cut a nd pinch or fall into
chain.
S Use the Reduced--Kickback Guide Bar
and Low--Kickback Chain specified for
your saw.
