_WARNING:
Avoid kickback
which
can result in serious
injury.
Kickback
is the backward,
upward or sudden for-
ward motion of the guide bar occurring
when the saw chain near the upper tip
of the guide bar contacts any object
such as a log or branch, or when the
wood closes in and pinches the saw
chain in the cut. Contacting
a foreign
object in the wood can also result in
loss of chain saw control.
• Rotational
Kickback can occur
when the moving chain contacts an
object at the upper 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 toward the operator.
• 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 sud-
den stopping
of the chain results in a
reversal of the chain force used to
cut wood and causes the saw to
move in the opposite
direction
of the
chain rotation. The saw is driven
straight back toward the operator.
• Pull-In can occur when the moving
chain contacts a foreign object in the
wood in the cut along the bottom of
the guide bar and the saw chain is
suddenly
stopped. This sudden stop-
ping pulls the saw forward
and away
from the operator and could easily
cause the operator to lose control of
the saw.
REDUCE
THE CHANCE
OF
KICKBACK
• Recognize that kickback can happen.
With a basic understanding
of kick-
back, you can reduce the element of
surprise which contributes to acci-
dents.
• Never let the moving
chain contact
any object at the tip of the guide bar.
• Keep working
area free from obstruc-
tions such as other trees, branches,
rocks, fences, stumps,
etc. Eliminate
or avoid any obstruction
that your
saw chain could hit while cutting.
• When cutting a branch, do not let the
guide bar contact another branch or
other objects around it.
• Keep saw chain sharp and properly
tensioned.
A loose or dull chain can
increase
the chance of kickback.
Follow manufacturer's
chain sharp-
ening and maintenance
instructions.
Check tension at regular intervals,
but never with engine running. Make
sure chain brake nuts are securely
tightened.
• Begin and continue
cutting at full
speed. If the chain is moving at a
slower speed, there is greater
chance of kickback occurring.
• Use extreme caution when reenter-
ing a cut.
• Do not attempt cuts starting with the
tip of the bar (plunge cuts).
• Watch for shifting
logs or other forces
that could close a cut and pinch or
fall into chain.
• Use the specified
Reduced-Kickback
Guide Bar and Low-Kickback
Chain.
Avoid Pinch-Kickback:
• Be extremely
aware of situations
or
obstructions
that can cause material
to pinch the top of or otherwise
stop
the chain.
• Do not cut more than one log at a
time.
• Do not twist saw as bar is withdrawn
from an undercut
when bucking.
Avoid Pull-In:
• Always begin cutting with the engine
at full speed and the saw housing
against wood.
• Use wedges made of plastic or
wood. Never use metal to hold the
cut open.
MAINTAIN
CONTROL
Stand to the left of the saw
Thumb on
underside
of h_
Elbow
locked
Never reverse hand positions
• A good, firm grip on the saw with both
hands will help you maintain control.
Don't let go. Grip the rear handle with
your right hand whether you are right
or left handed. Wrap the fingers of
your left hand over and around the
front handlebar, and your left thumb
under the front handlebar. Keep your
left arm straight with the elbow locked.
• Position your left hand on the front
handlebar
so it is in a straight line
with your right hand on the rear han-
dle when making
bucking cuts.
