Felling cut
D
Give a warning cry of "timber!" before
making the felling cut.
Make the felling cut (D) slightly
N
higher than the horizontal cut of the
felling notch
Exactly horizontal
–
approx. 1/10 of the diameter of the
–
trunk must remain standing
between the felling cut and the
notch = bridge
Insert wedges in the felling cut in time –
use only wedges made of wood, light
metal or plastic – no steel wedges. Steel
wedges damage the saw chain and can
cause kickback.

The bridge (E) functions as a hinge to
guide the tree to the ground.
Never saw through the bridge while
–
felling – otherwise the tree with fall
in a direction other than the one
planned – risk of accident!
With rotten trunks, leave a wider
–
bridge
Immediately before felling the tree, give
out a second warning cry of "timber!".
Thin trunks: simple fan cut
Engage the spiked bumper behind
N
the hinge. Pivot the machine around
this point – only as far as the bridge
– the spiked bumper rolls against
the trunk.
