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 easily 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 B 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. 001BA038 KN 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 handle 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. 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.

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.
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
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.
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.
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.
Cutting Techniques
Logs under strain:
Risk of pinching! Always start relieving

(1)
at compression side. Then make
bucking cut

at tension side. If the saw
pinches, stop the engine and remove it
from the log.
Only properly trained professionals
should work in an area where the logs,
limbs and roots are tangled. Working in
"blow down" areas is extremely

and cleared logs first.
If conditions allow, work from a lift
bucket.
