B = Pushback
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 log 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 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.
Logs under strain:
Risk of pinching! Always start relieving
cut (1) at compression side. Then make
bucking cut (2) 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
hazardous. Drag the logs into a clear
area before cutting. Pull out exposed
and cleared logs first.
If conditions allow, work from a lift
bucket.
WARNING
Be extremely cautious when cutting
limbs under tension (spring poles). The
limbs could spring back toward the
operator and cause loss of control of the
saw and severe or fatal injury to the
operator.
