GUARD AGAINST KICKBACK
Follow all safety rules to h e lp avoid kick-
back and other forces which can result in
serio us injury.
Kickback Path
Avoid Obstructions
Clear The Working Area
WARNING:
Avoid kickback which
can result in serious injury. Kickback is
the backward, upward or sudden for-
ward motion of the guide bar occurring
whenthe sawchain near theupper 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.
S
Rotational Kickback can occur when
the moving chain contacts an object at
the uppertip of theguide bar.This con-
tact 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 theguide
bar up and back toward 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 andthe saw chain
is suddenly stopped. This sudden
stopping of thechain results in arever-
sal of the chain force used to cut wood
and causes the saw to move in theop-
posite direction of the 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 along the bottom of the
guide bar and the saw chain is suddenly
stopped. This sudden stopping pulls the
saw forward and away from the opera-
tor and could easily cause the operator
to lose control of the saw.
REDUCE THE CHANCE OF
KICKBACK
The following precautions should be fol-
low ed to minimize kic kba ck:
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 object at the tip of the guide bar.
S
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.
S
When cutting a branch, do not let the
guide bar contact another branch or
other objects around it.
S
Keep saw chain sharp and properly
tensioned. Aloose or dull chain can in-
crease the chance of kickback. Follow
manufacturer’s chain sharpening and
maintenance instructions. Check ten-
sion atregular intervals, but never with
engine running. Makesure bar mount-
ing nuts are securely tightened.
S
Begin and continue cutting at full
speed. If the chain is moving at a slow-
er speed, there is greater chance of
kickback occurring.
S
Use extreme caution when re-enter-
ing a cut.
S
Donot attempt cuts starting with the tip
of the bar (plunge cuts).
S
Watch for shifting logs or other objects
that could close a cut and pinch or fall
onto chain.
S
Use the specified Reduced-Kickback
Guide Bar and Low Kickback Chain.
A void Pinch-Kickback:
S
Be extremely aware of situations or
obstructions 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 buck-
ing.
A void Pull-In:
S
Always begin cutting with the saw 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.
MAINTAIN CONTROL
The following precautions should be fol-
low ed to minimize kic kba ck.
S
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.
