•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 coutd easily cause the
operator to lose control dthe 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 pIastic or wood.
Never use metal to hoid the cut open
Kickback Path
Working Area _J
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.
Make sure the chain brake nuts are se-
curely tightened after tensioning the chain
• Begin and continue cutting at full speed. If
the chain is moving at a slower speed, there
_sgreater chance of kickback occurring.
• Cut one Iog at a time
• Use extreme caution when re-enteedg a
previous cut.
• Do not attempt cuts starting with the tip of
the bar (p}unge cuts)
• Watch for shifting logs or other forces that
could close a cut and pinch or fal_ into
chain
• Use the Reduced-Kickback Guide Bar
and Low-Kickback Chain specified for
your saw.
MAINTAIN CONTROL

• Keep a good, firm gnP on the saw with both
hands when the engine is running and don't
let go. A firm grip will help you reduce kick-
back and maintain control of the saw. Keep
the fingers of your left hand encircling and
your left thumb under the front handlebar
Keep your right hand completely around the
rear handle whether your are right handed or
left handed. Keep your left arm strd_ght with
the elbow locked.
• 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
