KICKBACK
WARNING:
Avoid kickback which
can result in serious injury.
Kickback
is the
backward, upward orsudden forward motion
of the guide bar occurring when the saw
chain near the upper tip of the guide bar con-
tacts any object such as a log or branch, or
when the wood closes in and pinches the
saw chain in the cut. Contacting aforeign ob-
ject in the wood can also result in loss of
chain saw control.
S
Rotational Kickback
can occur when the
moving chain contacts an object at the up-
per tip of the guide bar. This contact 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 to-
ward the operator.
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
sawtomove inthe opposite direction ofthe
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 w ood in the
cut along the bottom of the guide bar and the
saw chain is suddenly stopped. This sudden
stopping pulls the saw forw ar d and away
from the operatorand could easily cause the
operator to lose control of the saw.
A v oid Pinch--Kickback:
S
Be extremely aware of situations or ob-
structions that can cause material to pinch
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 P ull--In:
S
Always begin cutting with the engine at full
speed and the saw housing against wood.
S
Use wedges made of plastic or wood.
Never use metal to hold the cut open.
Kickback Path
Avoid Obstructions
Clear The Working Area
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
Never let the moving chain contact any ob-
ject at the tip of the guide bar.
S
Keep the working area free from obstruc-
tions such as othertrees, 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
and maintenance instructions. Check ten-
sion at regular intervals with the engine
stopped, never with the engine running.
Make sure the chain brake nuts are se-
curely tightened after tensioning the 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 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.
