WARNING: Avoid kickback which
can result in serious injury. Kickback is
the backward, upward or sudden for-
ward motion of the guide bar occ urring
when the sawchainnearthe uppertip 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 RotationalKickback can occurwhen
the movingchain contacts anobjectat
theuppertipoftheguidebar.T hiscon-
tactcan cause the chain todig into the
object, which stops the chain for an
instant. The result is a lightning fast,
reverse reaction whichk icks theguide
bar up and back toward the operator.
S Pinch-Kickback can o ccur 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
stoppingof thechain resultsin arever-
sal ofthe chainforce used to cut wood
and causes thesaw to move in theop-
posite direction of the chain rotation.
The saw is drivenstraightback toward
the operator.
S Pull-In canoccurwhenthemoving
chain contacts a foreign object in the
wood in thec utalong thebottomofthe
guide bar and the saw chain is sud-
denly stopped. This sudden s topping
pulls the saw forward and away from
the operator and could easily cause
the operator to lose controlof the saw.
REDUCE THE CHANCE OF
KICKBACK
The f oll owi ng pr ecauti ons shoul d b e f ol-
lowed to minimize kickback:
S Recognize that kickback can happen.
Wit h a basic understanding of kickback,
you can re duce the ele m ent of surp rise
which cont r i butes to accident s.
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 obs truction 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 c hain sharp and properly
tensioned.A looseor dullchain can in-
crease the chance ofkickback.Follow
manufacturer’s chain sharpening and
maintenance instructions. Check ten-
sionatregularintervals,but neverwith
enginerunning.Make sure barmount-
ing nuts are securely tightened.
S Begin and continue cutting at full
speed. Ifthe chainis movingata slow-
er speed, there is greater chance of
kickback occurring.
S Use extreme caution when re-enter-
ing a cut.
S Do not attempt cuts starting with the tip
of the bar (plunge cuts).
S Watch fors hifting 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.
Avoid Pinch--Kickback:
S Be extremely aware of sit uat i ons or ob-
str u cti ons that can cause mat e rial to
pinch the to p of o r o therwi se stop the
chain.
S Do notcut more thanone log ata time.
S Do not twist t he saw as t he bar is wit h-
drawn fr om an undercut when bucking.
A voi d Pull-I n :
S Always begin cutting with the saw at
full spe ed and the saw housing
against wood.
S Use wedges made of plastic or wood.
Never use metal to hold the cut open.
