• Pinch-Kickback can occur when the the
wood closes inand pinches the moving
saw chain inthe cut a long the top ofthe
guide bar a nd t he saw chain i ssuddenly
stopped. This sudden stopping ofthe
chain r esults ina reversal ofthe chain
force u sed tocut w ood a nd causes the
saw to move in the o pposite direction ofthe
chain rotation. The s aw isdriven 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 d 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 engine at full
speed and the saw housing against wood.
• Use wedges made of plastic or wood.
Never use metal to hoid the cut open
Make sure the chain brake nuts are se-
curely tightened after tensioning the chain
• SeginandcontinuecuttingatfulIspeed. If
the chain is moving at a slower speed,
there is greater chance of kickback occur-
ring
• 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 (pIunge cuts).

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 loose 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.
Thumb on underside of
handlebar
• Keep a good, firm gbp on the saw wkh both
hands when the engine is running and
don't }et 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 right hand com-
pletely around the rear handle whether
your are right handed or left handed Keep
your left arm straight with the elbow
Iocked.
• Position your Ieft hand on the front handle-
bar so it is in a straight line with your right
hand on the rear handle when making
bucking cuts. Never reverse right and Ieft
hand positions for any type of cutting.
• Stand with your weight evenly balanced on
both feet.
• Stand slightly to the left side of the saw to
keep your body from being in a direct line
with the cutting chain
• Do not overreach. You could be drawn or
thrown off balance and lose control of the
saw
