PETROL CHAIN SAW FOR TREE SERVICE USER MANUAL
Before carrying out a critical cut,
the operator must always check
that there is enough fuel in the tank.
8.7 USING THE CHAIN SAW WITH ONE HAND
- Do not use the chain saw for tree service with
one hand:
- in an unstable position;
- when cutting branches of small diameter parts
of the tree and at the top of trees.
- The chain saw for tree service can be used
with one hand in the following circum-
stances:
1) when no other working position suitable for
working with 2 hands can be found;
2) when ensuring a working position with the left
hand is required;
3) when the operator needs to lean forward a lot
(see fig.17).
The operator must never:
1) Cut branches using the nose of the guide bar
subject to kickback (see chapter 2 paragraph
A.19);

THE DANGER OF
KICKBACK
2) hold and cut the part of the branch to be re-
moved;
3) try to hold a falling branch.
SPIKE: When cutting very thick branches, it is
useful to penetrate the wood with the spike teeth,
to cut with less effort and for a more controlled
cutting action.

8.8 REMOVING THE GUIDE BAR STUCK IN
THE WOOD
- If the guide bar and the chain are stuck in the
wood during the cutting operation, proceed as
follows:
1) with the engine off, tie the chain saw to the
tree (towards the trunk) by using an additional,
separate rope;
2) remove the chain saw from the cut by mov-
ing and lifting the branch;
3) if necessary, use a hand saw or a second
petrol chain saw by making a cut at least 30cm
(from the stuck chain saw) towards the end of
the branch in order to stop the branch from fall-
ing with the chain saw and therefore to cause
additional problems.
WARNING
Using a mechanical basket (where possible)
is still the safest solution to ensure the op-
timal operation of the chain saw (see fig.18).

8.9 CHAIN BRAKE

Your chain saw is fitted with a safety chain brake
to lock the chain in position (in the event of a
kickback) in a fraction of a second.
-The brake is automatically operated in the event
of a kickback by the inertia of the brake lever
(fig.30).
