angle 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
4. On the side of the fall, mark a felling notch
around a third of the trunk's diameter.
5. 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.
6. Reduce the thickness of this hinge without
pulling out the bar, until the tree falls.
7. 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.

WARNING!
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..
1. Check the direction in which the branch is
attached to the tree
2. First cut on the side where the branch bends
and then finish cutting on the opposite side.

8. MAINTENANCE AND STORAGE

Correct maintenance is essential to maintain the
original efficiency and safety of the machine over
time.

• Sawing logs (Fig. 16)
It is easier to saw a log using the spiked bumper.
1. Dig the spiked bumper into the log and use it
as a pivot. Cut with an arched motion to make
the bar penetrate the wood.
2. Repeat several times if necessary, changing
the point where you plant the spiked bumper.
• Sawing a log on the ground (Fig. 17)
Cut up to half the diameter, roll the log over and
finishing sawing on the other side.
• Sawing a raised log (Fig. 18)
1. If you are sawing the overhanging end of a
supported log (A), first cut a third of the diam-
eter from the bottom upwards, then finish
from the top.
2. 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.

– Never dispose of oils, fuel or other polluting
materials in unauthorised places.
CYLINDER AND SILENCER (Fig. 19)
To reduce fire risks, periodically clean the cylin-
der flaps with compressed air and clear the
silencer area to get rid of sawdust, branches,
leaves or other debris.
