Using the machine
4. Prepare an undercut on the felling side of the
tree with a depth of approx. 1/3 of the diame-
ter of the trunk.
5. Cut into the tree on the opposite side at a po-
sition slightly above the horizontal cut of the
felling notch, and leave a bridge (1) of approx.
5–10 cm.
6. Slowly reduce the thickness of the bridge, wi-
thout pulling out the bar, until the tree falls.
7. Under particular conditions or if there is low
stability, felling can be completed by inserting
wedges (2) into the undercut and driving them
in with a hammer.
Cutting off branches after felling (Fig. 15)
Pay attention to where the branch is
in contact with the ground because it
is possible for the branch to be under
tension, consider the direction that the
branch will move in when cut and the
possible instability of the tree after the
branch has been cut.
1. Take account of the direction in which the
branch is growing out of the trunk.
2. Make the first cut on the side with the bend,
and complete the cut on the opposite side.
Cutting through a trunk on the ground (Fig.
17)
1. Cut through the trunk to about the middle of
its diameter, roll the trunk and complete the
cut on the opposite side.
Cutting through a raised trunk (Fig. 18)
1. If the majority of the cut is to be made opposite
to the contact points (A), cut one third of the
diameter from underneath and then complete
the work from above.
2. If the cut is made between two contact points
(B), cut one third of the diameter from above
and complete the work from below.
Completing work
When the work is done:
1. Switch off the engine as described above
(section 6).
2. Wait for the chain to come to a complete
standstill and allow the machine to cool down.
3. Loosen the fastening nut on the bar so as to
reduce the chain tension.
4. Remove all traces of saw chips or oil residues.

5. If the chain is highly contaminated or gummed
with resin, remove it and leave it to soak for
a few hours in a container of special cleaner.
Then rinse with clean water and spray with
an appropriate anticorrosion product before
installing on the machine.
6. Fit the chain guard before putting the machine
away.
CAUTION!
Allow the engine to cool down before you
place the machine in a room. To reduce
the risk of fire, the machine must be clea-
ned to remove saw chips, twigs, leaves
or surplus grease; do not store contai-
ners with cutting residues inside rooms.

MAINTENANCE AND STORAGE

For your safety and the safety of others:
Correct maintenance is essential to retain the
original efficiency and working safety of the
machine.
Make sure that all nuts and screws are firmly
tightened so as to be certain that the machine
is always operating under good conditions.
Never use the machine with worn or dama-
ged components. The damaged parts must
be renewed and are never allowed to be re-
paired. Use original spare parts only. Non-
equivalent spare parts can damage the ma-
chine and endanger the operator.
During maintenance work:
Remove the spark plug connector.
Wait until the motor has cooled down suffici-
ently.
Wear protective gloves when working on the
bar and the chain.
Do not remove the chain guard unless you
need to work on the bar or the chain themsel-
ves.
Dispose of oils, petrol or other contaminating
substances according to the regulations.
Cylinder and silencer (19)
To reduce the risk of fire to a minimum, frequently
clean the cylinder vanes with compressed air and
keep the area around the silencer free from twigs,
cuttings, leaves or other residues.
Starter group
Always keep the cooling air intake grille clean and
free from saw chips and dirt at all times to prevent
