S Mix and pour fuel in an outdoor area onbare
ground; store fuel in a cool, dry, well venti-
lated place; and use an approved, marked
container for all fuel purposes. Wipe up all
fuel spills before starting saw.
Kickback Path
S Move at least 10 feet (3 meters) from fuel-
ing site before starting engine.
S Turn the engine off and let saw cool in a
non-combustible area, not on dry leaves,
straw, paper, etc. Slowly remove fuel cap
and refuel unit.
Avoid Obstructions

vapors cannot reach sparks or open
flames from water heaters, electric motors
or switches, furnaces, etc.
Clear The
Working Area
REDUCE THE CHANCE OF
KICKBACK
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 letthemovingchaincontactanyob-
ject at the tip of the guide bar.
S Keep the 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 you are cutting through a particular log
or branch.
WARNING: Avoid kickback which
can result in serious injury. Kickback is the
backward,upwardorsuddenforwardmotion
of the guide bar occurring when the saw
chainnear theupper tip oftheguidebarcon-
tacts any object such as a log or branch, or
when the wood closes in and pinches the
saw chaininthecut.Contactingaforeignob-
ject in the wood can also result in loss of
chain saw control.
S Rotational Kickback can occur when the
moving chain contacts an objectat theup-
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
sawtomoveintheoppositedirectionofthe
chain rotation. The saw is driven straight
back toward the operator.
S Keep your saw chain sharp and properly
tensioned. Alooseordullchaincanincrease
the chance of kickback occurring. Follow
manufacturer’s chain sharpening and main-
tenanceinstructions. Checktensionatregu-
lar intervals with the engine stopped, never
with the engine running. Make sure the bar
clamp nuts are securely tightened after ten-
sioning 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 occurring.
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 Pull-In can occur when the moving chain
contacts a foreign object in the wood in the
cutalongthebottom ofthe guidebar andthe
saw chainis suddenly stopped. This sudden
stopping pulls the saw forward and away
fromtheoperator and couldeasily causethe
operator to lose control of the saw.
S
Use the Reduced--Kickback Guide Bar
and Low--Kickback Chain specified for
your saw.
MAINTAIN CONTROL
Avoid Pinch--Kickback:
Stand to the left of
the saw
S Be extremely aware of situations or obstruc-
tions thatcancausematerial topinch thetop
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 Pull--In:
S Always begin cutting with theengine atfull
speed and the saw housing against wood.
S Use wedges made of plastic or wood.
Never use metal to hold the cut open.
Never reverse
hand positions
