11.8 Limbing
► Support the chainsaw on the log.
► With the chain running a full speed, pivot the
guide bar downward against the limb.
► Cut through the limb with the top of the guide
bar.
► If the limb is under tension: Make the relieving
cut (1) at the compression side and then per‐
form the bucking cut (2) from the tension side.
11.9 Felling
11.9.1 Determining direction of fall and
escape path
► Determine direction of fall so that the area in
which the tree falls is clear.
► Observe the following points when planning
escape path (B):
–
Escape path (B) at an angle of 45° to direc‐
tion of fall (A).
–
No obstacles on the escape path (B).
–
The top of the tree can be observed.
–
If the escape path (B) is on a slope, it must
be parallel to the slope.
11.9.2 Preparing work area at base of tree
► Remove obstacles from work area at tree
base.
► Remove growth from tree base.
► If the tree has large, healthy buttress roots:
Make vertical cut first and then a horizontal
cut, and remove the resulting piece.

C Felling notch
The felling notch determines the direction of
fall.
D Hinge
The hinge helps control the falling tree. The
width of the hinge is 1/10 of the trunk diame‐
ter.
E Felling cut
The tree is felled with the felling cut. The fell‐
ing cut is 1/10 of the trunk diameter (at least 3
cm) above the bottom of the felling notch.
F Stabilizing strap
The stabilizing strap supports the tree and
helps prevent it from falling prematurely. The
width of the stabilizing strap is 1/10 to 1/5 of
the trunk diameter.
G Holding strap
The holding strap supports the tree and helps
prevent it from falling prematurely. The width
of the holding strap is 1/10 to 1/5 of the trunk
