PEtROL CHAiN SAW FOR tREE SERViCE USER MANUAL
- 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
removed;
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 moving
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 falling 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 optimal
operation of the chain saw (see fig.18).
