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.
S
Store the unit and fuel in an area where fuel
vapors cannot reach sparks or open
flames from water heaters, electric motors
or switches, furnaces, etc.
KICKBACK
WARNING
:
Avoid kickback which
can result in serious injury.
Kickback
is the
backward, upward or sudden 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 a foreign 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
saw to move in the opposite 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 operator and could easily cause the
operator to lose control of the saw.
Avoid Pinch--Kickback:
S
Be extremely aware of situations or obstruc-
tions 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 Pull--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 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.
S
Keep your saw chain sharp and properly
tensioned. A loose or dull chain can increase
the chance of kickback occurring. Follow
manufacturer’s chain sharpening and main-
tenance instructions. Check tension at regu-
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
Use the Reduced--Kickback Guide Bar and
Low--Kickback Chain specified for your saw.
MAINTAIN CONTROL
Never reverse
hand positions
Stand to the left of
the saw
Thumb on underside of
handlebar
Elbow locked
