– Decide where the tree should fall - you should
consider the wind, the natural lean of the tree,
the position of the heaviest branches and how
easy the work is after felling, etc.
– Clear the area around the tree and find a sta-
ble place to stand.
– Plan obstacle-free escape routes at a 45° an-
gle back and away from the direction of fall.
These routes must allow you reach a safe area
at a distance of about 2.5 times the length of
the tree to be felled
– On the side of the fall, mark a felling notch a-
round a third of the trunk’s diameter.
– Cut the tree on the other side, slightly above
the bottom of the notch, leaving the uncut
wood to act as a “hinge” (1) of approx. 5-10
cm.
– Reduce the thickness of this hinge without
pulling out the bar, until the tree falls.
– In particular or unstable conditions, you can
complete felling by inserting wedges (2) on the
opposite side of the fall, and hitting them with
a hammer until the tree falls.
• Bucking (Fig. 11)
Be careful of where the
branches are lying on the ground, the risk of
them being under tension, the direction the
branch may go during cutting and the risk of
the tree being unstable after the branch has
been cut.
– Check the direction in which the branch is at-
tached to the tree
– First cut on the side where the branch bends
and then finish cutting on the opposite side.
• Sawing a log on the ground (Fig. 12)
Cut up to half the diameter, roll the log over and
finishing sawing on the other side.
!
WARNING!
• Sawing a raised log (Fig. 13)
– If you are sawing the overhanging end of a
supported log (A), first cut a third of the dia-
meter from the bottom upwards, then finish
from the top.
– If you are sawing between two supports (B),
cut a third of the diameter from the top down-
wards, then finish from the bottom.
END OF OPERATIONS
When you have finished your work:
– Switch off the engine as indicated above
(Chap. 6).
– Wait for the chain to stop and then mount the
bar cover.
