KICKBACK
_IWARNING;
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 tog 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.
• 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.
• 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.
• Pull4n
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:
• Be extremely
aware
of situations
or ob-
structions
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 the saw as the bar is with-
drawn from an undercut
when bucking,
Avoid
Pull-In:
• Always begin cutting with the engh_e at full
speed and the saw housh_g against wood.
• Use
wedges
made
of plastic
or wood.
Never use metal to hold the cut open.

REDUCE
THE
CHANCE
OF
KICKBACK
• Recognize
that
kickback
can
happen.
With a basic understanding
of kickback,
you can reduce
the element
of surprise
which contributes
to accidents.
• Never let the moving chain contact any ob-
ject at the tip of the guide bar.
• 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.
When
cutting a
branch,
do not let the guide
bar contact
branch or other objects around
it.
• Keep your saw chain sharp and properly
tensioned.
A _oose or dull chain can in-
crease the chance
of kickback
occurring.
Follow
manufacturer's
chain sharpening
and maintenance
instructions.
Check ten-
sion at regular
intervals
with
the engine
stopped,
never with the engine
running.
Make sure the bar nuts are securely tight-
ened after tensioning
the chain.
• Begin and continue cutting at fuli speed.
If
the chain is moving at a slower speed, there
is greater chance of kickback occurring.
• Cut one log at a time.
• Use extreme
caution
when re-entering
a
previous
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 Reduced-Kickback
Guide
Bar
and
Low-Kickback
Chain
specified
for
your saw.

• Keep a good, firm grip on the saw with both
hands
when
the engine
is running
and
don't let go. A firm grip will help you reduce
kickback
and maintain
control of the saw.
Keep the fingers
of your left hand encir-
cling and your left thumb
under the front
handlebar.
Keep your
