N
Snap the meter stick in the middle
and create an isosceles triangle
N
Position both ends of the meter stick
in the front trunk area (1/5 to max.
1/3 of the trunk diameter) – align the
tip of the meter stick in the defined
direction of fall
N
Mark the trunk at both ends of the
meter stick to limit the felling notch
Making a felling notch
When making a felling notch, align the
machine so that the notch lies at a right
angle to the direction of fall.
During the procedure various
sequences are permitted for making a
felling notch with a bottom (horizontal)
cut and top (angled) cut – comply with
national legislation regarding felling
technique.
N
Make the bottom cut (horizontal cut)
– until the guide bar reaches both
markings
N
Make the top (angled) cut
approx. 45°
-
60° to the bottom cut
Checking the direction of fall
The bottom cut and top cut must meet in
a continuous straight sink chord.
N
Position the meter stick at the pivot
point of the sink chord – the tip of the
meter stick must point in the
direction of the specified direction of
fall – where necessary, correct the
direction of fall by cutting the felling
notch accordingly
Sapwood cuts
With long-fibered wood, sapwood cuts
prevent the sapwood from splintering
when felling the trunk – saw both sides
of the trunk at the level of the felling
notch base to approx. 1/10 of the
diameter of the trunk – with thicker
trunks, not more than the width of the
guide bar.
Do not use sapwood cuts on diseased
trees.
