8. Use extreme caution when
reentering a previous cut.
9. Do not attempt to plunge cut if you
are not experienced with these
cutting techniques.
10. Be alert for shifting of the branch or
other forces that may cause the cut
to close and pinch the saw chain.
11. Maintain saw chain properly. Cut
with a correctly sharpened, properly
tensioned saw chain at all times.
12. Stand to the side of the cutting path
of the chain saw.
Bow Guides
WARNING
Do not mount a bow guide on any STIHL
chain saw. Any chain saw equipped with
a bow guide is potentially very
dangerous. The risk of kickback is
increased with a bow guide because of
the increased kickback contact area.
Low kickback saw chain will not
significantly reduce the risk of kickback
injury when used on a bow guide.

A = Pull-in
Pull-in occurs when the saw chain on the
bottom of the bar is suddenly stopped
when it is pinched, caught or encounters
a foreign object in the wood. The
reaction of the saw chain pulls the chain
saw forward and may cause the
operator to lose control.
Pull-in frequently occurs when the
bumper spike of the chain saw is not
held securely against the tree or limb
and when the saw chain is not rotating at
full speed before it contacts the wood.
WARNING
Use extreme caution when cutting small
size branches which may easily catch
the saw chain, be whipped towards you
or pull you off balance.
To avoid pull-in
1. Always start a cut with the saw
chain rotating at full speed and the
bumper spike in contact with the
wood.
2. The risk of pull-in may also be
reduced by using wedges to hold
open the kerf or cut.
B = Pushback
A
Pushback occurs when the saw chain on
the top of the bar is suddenly stopped
when it is pinched, caught or encounters
a foreign object in the wood. The
reaction of the saw chain may drive the
chain saw rapidly straight back toward
the operator and may cause loss of
chain saw control, which, in turn, may
cause serious or fatal injury. 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 to pinch the top
of the saw chain.
2. Do not cut more than one branch at
a time.
3. Do not twist the chain saw when
withdrawing the bar from a plunge
cut or underbuck cut because the
saw chain can pinch.
WARNING
This lightweight chain saw equipped
with a top handle is designed specifically
for in-tree surgery and maintenance. If
the operator is not proberly secured for
