11.5.6 Selecting the Appropriate Felling Cut
The choice of appropriate felling cut depends on the
following conditions:
– The natural inclination of the tree
– The tree’s branch formation
– Damage to the tree
– The tree’s state of health
– If there is snow on the tree: the snow load
– The direction of slope
– Wind direction and speed
– Nearby trees, if any
There are different features of these conditions. Only two
features are described in this Instruction Manual.
1 Normal tree
A normal tree is vertical and has an even crown.
2 Leaner
A leaner stands at an angle and the crown faces in the
direction of fall.
11.5.7 Felling normal, small diameter tree
A normal tree is felled with a felling cut and stabilizing strap.
This felling cut must be performed if the tree diameter is less
than the guide bar’s length.
► Shout a warning.
► Plunge the guide bar into the felling cut until it is visible at
the other side of the trunk, @ 11.5.5.
► Apply the spiked bumper behind the hinge and use it as a
pivot.
► Enlarge felling cut in direction of hinge.
