PETROL CHAIN SAW FOR TREE SERVICE USER MANUAL
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 possi-
ble) is still the safest solution to ensure the
optimal 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).
Always hold the chain saw with both hands
(wherever possible).
- The chain brake can also be manually inserted
by pushing it forward.
- To release the brake, pull the lever towards the
handles (fig.36).

- Before starting any cutting operation, manu-
ally check that the lever clicks into the forward
and backward position.
Check its operation as follows:
-
manually apply the brake (fig.30);
- start the engine;
- push the throttle lever all the way for a few sec-
onds (fig.34 item B);
- the chain must not move on the guide bar.
If the lever does not click into po-
sition, if it becomes harder to op-
erate the lever and if the chain moves along
the guide bar, do not use the chain saw.
