enced when working with it are generally not as severe as
those encountered with a chain saw. Nevertheless, you
should always maintain a proper grip and good footing to
control the power tool when you experience such forces.
The most common reactive forces are:
• kickback,
• pushback,
• pull-in.
Kickback
Kickback may occur when the moving saw chain near the
upper quadrant of the bar nose contacts a solid object or
is pinched.
The reaction of the cutting force of the chain causes a
rotational force on the chainsaw in the direction opposite
to the chain movement. This may cause the bar to move
upward.
To avoid kickback
The best protection from kickback is to avoid kickback
situations:
1. Be aware of the location of the guide bar nose at all
times.
2. Never let the nose of the guide bar contact any object.
Do not cut limbs with the nose of the guide bar. Be
especially careful near wire fences and when cutting
small, tough limbs, which may easily catch the chain.
3. Cut only one limb at a time.
A = Pull-in
Pull-in occurs when the chain on the bottom of the bar
is suddenly stopped when it is pinched, caught or en-
counters a foreign object in the wood. The reaction of
the chain pulls the saw forward. Pull-in frequently occurs
when the chain is not rotating at full speed before it con-
tacts the wood.
To avoid pull-in
1. Be alert to forces or situations that may cause material
to pinch the chain at the bottom of the bar.

2. Always start a cut with the chain rotating at full speed.
B = Pushback
Pushback occurs when the chain on the top of the bar
is suddenly stopped when it is pinched, caught or en-
counters a foreign object in the wood. The reaction of the
chain may drive the saw rapidly straight back toward the
operator. Pushback frequently occurs when the top of the
bar is used for cutting.
To avoid pushback
1. Be alert to forces or situations that may cause material
