Limbing A Tree - Kress KG367E.9 Bedienungsanleitung

notified immediately.
The Chainsaw operator should keep on the uphill side
of the terrain as the tree is likely to roll or slide downhill
after it is felled.
An escape path should be planned and cleared as
necessary before cuts are started. The escape path
should extend back and diagonally to the rear of the
expected line of fall as illustrated in Figure 1.
Before felling is started, consider the natural lean of the
tree, the location of larger branches and the wind direction
to judge which way the tree will fall.
Remove dirt, stones, loose bark, nails, staples and wire
from the tree.
2. Notching undercut
Make the notch 1/3 the diameter of the tree,
perpendicular to the direction of falls as illustrated in
Figure 1. Make the lower horizontal notching cut (W) first.
This will help to avoid pinching either the saw chain or the
guide bar when the second notch (X) is being made.
3. Felling back cut
Make the felling back cut (Y) at least 50 mm higher than
the horizontal notching cut as illustrated in Figure 1. Keep
the felling back cut parallel to the horizontal notching cut.
Make the felling back cut so enough wood is left to act
as a hinge. The hinge wood keeps the tree from twisting
10
and falling in the wrong direction. Do not cut through the
hinge.
EN
As the felling gets close to the hinge, the tree should
begin to fall. If there is any chance that the tree may not
fall in desired direction or it may rock back and bind the
saw chain, stop cutting before the felling back cut is
complete and use wedges of wood, plastic or aluminium
(Z) to open the cut and drop the tree along the desired line
of fall ( ).
When the tree begins to fall remove the Chainsaw from
the cut, stop the motor, put the Chainsaw down, then
use the retreat path planned (
limbs falling and watch your footing. (See Figure 1)

4. Limbing a tree

Limbing is removing the branches from a fallen tree. When
limbing leave larger lower limbs to support the log off the
ground. Remove the small limbs in one cut as illustrated in
Figure 2. Branches under tension should be cut from the
bottom up to avoid binding the Chainsaw.

5. Bucking a log
Bucking is cutting a log into lengths. It is important to
make sure your footing is firm and your weight is evenly
distributed on both feet. When possible, the log should be
raised and supported by the use of limbs, logs or chocks.
Follow the simple directions for easy cutting.
When the log is supported along its entire length as
illustrated in Figure 3, it is cut from the top (overbuck),
avoid contacting ground as this will greatly reduce the
chain sharpness.

When the log is supported on one end, as illustrated in
Figure 4, cut 1/3 the diameter from the underside (
underbuck) (1). Then make the finished cut by

overbucking (2) to meet the first cut.
