4. Don't overreach.
5. Don't cut above shoulder height.
6. Begin cutting and continue at full
throttle.
7. Cut only one log at a time.
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 log or
other forces that may cause the cut
to close and pinch the chain.
11. Maintain saw chain properly. Cut
with a correctly sharpened, properly
tensioned chain at all times.
12. Stand to the side of the cutting path
of the chain saw.
A = Pull-in
Pull-in occurs when the 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 chain pulls the saw
forward and may cause the operator to
lose control.
16
Pull-in frequently occurs when the
bumper spike of the saw is not held
securely against the tree or limb and
when the chain is not rotating at full
speed before it contacts the wood.
Warning!
Use extreme caution when cutting small
size brush and saplings which may eas-
ily catch the chain, be whipped towards
you or pull you off balance.
To Avoid Pull-in
1.
Always start a cut with the 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 open
the kerf or cut.
B = Pushback
A
Pushback occurs when the 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 chain may drive the saw rapidly
straight back toward the operator and
may cause loss of saw control.
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 chain.
2.
Do not cut more than one log at a
time.
3.
Do not twist the saw when
withdrawing the bar from a plunge
cut or underbuck cut because the
chain can pinch.
4.
Do not underbuck freely hanging
limbs because the chain may get
pinched and cause pushback and
loss of control.
Warning!
This chain saw equipped with a top han-
dle is designed specifically for tree
surgery and maintenance. Due to the
special handle design (closely spaced
handles), there is an increased risk of
injury from loss of control.
For this reason this special chain saw
should be used only for work in a tree by
persons trained in special cutting and
working techniques. This type of chain
saw is not designed for cutting work on
the ground, such as felling and bucking.
B
Because this chain saw is not intended
for use on the ground, this manual does
not contain instructions for felling or for
limbing and bucking felled trees. For
instructions on these techniques when
using other STIHL chain saw models,
see the instruction manuals for these
saws or the STIHL Chain Saw Safety
Manual, which is available free from
your STIHL servicing dealer.
