► Use a low kickback saw chain and proceed
with special care
1. Begin cut by applying the lower portion of the
guide bar nose – do not use upper portion
because of risk of kickback. Cut at full
strength until the depth of the kerf is twice
the width of the guide bar
2. Swing the machine slowly into the plunge
cutting position – risk of kickback and push‐
back!
3. Make the plunge cut very carefully. Risk of
pushback.

Where possible, use a plunge blade. The plunge
blade and the upper/lower side of the guide bar
are parallel.
During plunge cutting, the plunge bar helps to
keep the hinge parallel in form, i.e. the same
thickness at all points. To do this, guide the
plunge bar parallel to the sink chord.
Felling wedges
Insert the felling wedge as soon as possible, i.e.
as soon as no obstruction of saw control is to be
expected. Position the felling wedge in the felling
cut and drive in with suitable tools.
Only use aluminum or plastic wedges – do not
use steel wedges. Steel wedges can seriously
damage the saw chain and cause dangerous
kickback.
Select suitable felling wedges dependent on the
trunk diameter and the width of the kerf (ana‐
logue to felling cut (E)).
Contact the STIHL dealer for the selection of the
felling wedge (suitable length, width and height).
4.6
Selecting the appropriate felling
cut
The selection of the appropriate felling cut is
dependent on the same tree characteristics that
must be noted when determining the direction of
fall and the escape paths.
There are various different features of these
characteristics. This User Manual will only
describe the two most commonly occurring var‐
iants:
001BA260 KN
left:
Normal tree – vertically upright tree
with uniform crown
right:
Leaner tree - crown pointing in direc‐
tion of fall

Felling cut with stabilizing strap
(normal tree)
A) Thin trunks
Implement this felling cut when the trunk diame‐
ter is smaller than the cutting length of the chain‐
saw.
