Felling notch
Preparing the felling notch
The felling notch (C) determines the
direction of fall.
Important:
– Make a felling notch at right angle to
direction of fall
– Saw as close to the ground as
possible
– Cut to a depth of approx. 1/5 to 1/3
of the diameter of the trunk
Specify the direction of fall – without the
gunning sight on the shroud and fan
housing
If the chain saw is designed without the
gunning sight on the shroud and fan
housing, the direction of fall can be
determined or controlled using a meter
stick:
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
