Cutting Techniques - Stihl MSE 220 Instruction Manual

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 drives the saw 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.

Warning!
Working with an electric chain saw in the
woods - i.e. felling or limbing - is very
dangerous. The freedom of movement
necessary for this work is impaired by
the power cable! Electric saws are
intended for stationary use in yards,
B
buildings, etc.

Cutting Techniques

These general instructions apply to all
chain saws. As stated above, however,
STIHL recommends against use of your
electric saw in the woods.
Felling
Felling is cutting down a tree.
Before felling a tree, consider carefully
all conditions which may affect the
direction of fall, including:
The intended direction of the fall.
The natural lean of the tree.
Any unusually heavy limb structure.
Surrounding trees and obstacles.
The wind direction and speed.
!
Warning!
Always observe the general condition of
the tree. Inexperienced users should
never attempt to cut trees which are
decayed or rotted inside or which are
leaning or otherwise under tension.
There is an increased risk that such
trees could snap or split while being cut
and cause serious or fatal injury to the
operator or bystanders. Also look for
broken or dead branches which could
vibrate loose and fall on the operator.
When felling on a slope, the operator
should stand on the uphill side if
possible.
