11.4.6 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.

11.4.7 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, @ 11.4.5.

► Apply the spiked bumper behind the hinge and use it as a

pivot.

► Enlarge felling cut in direction of hinge.

► Enlarge felling cut in direction of stabilizing strap.

► Insert a felling wedge. The felling wedge must match the

tree diameter and the width of the felling cut.

► Shout a warning.

► With outstretched arms, cut through the stabilizing strap

horizontally from outside at the same level as the felling

cut.

The tree falls.
