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

gunning sight on the shroud and fan
housing, the direction of fall can be
determined or controlled using a meter
