and increase the possibility of kickback.
- Always keep the handles dry and clean.
- When cutting a limb that is under tension, be
alert for springback so you will not be struck
when the tension in the wood fibre is released.
- Take great care when cutting small branches or
shrubs which can block the chain, be thrown back
towards you or cause you to lose your balance.
PRECAUTIONS FOR USING THE MACHINE
1. The specially shaped handgrip on the
machine calls for particular care when dealing
with kickback.
2. Extreme care should be taken at the end of a
cutting operation in relation to the machine
suddenly dropping. This eventuality is difficult
to control with this type of handgrip.
3. Attention should be paid to chain sliding.
Instead of penetrating the tree trunk, the
chain may slide forward and the operator will
not be able to fully control this action.
4. Tree maintenance operators must be trained
in th e cor re c t op erative tech n iqu es
concerning safety at work, i.e.: headgear,
safety harnesses, cables and spring-clips, as
well as all of the other safety devices that are
n or m a l l y use d an d m ust b e train ed
professionally in tree climbing.
5. The ISO 11681-2 regulation permits that, in
hands of a trained operator, it can be used an
one hand, carefully using a safe way of work
(only for tree surgery). For all other
operations it is compulsory to use it with
t wo h a n d s i n t h e s a m e w a y a s a
conventional chain saw.
WARNING! - WE STRONGLY RECOMMEND
NOT TO USE THIS CHAIN SHOW WITH ONE
HAND ONLY.
Using the chain saw with only one hand is

significantly increase the possible occurrence
of the dangers listed (1÷4) above.
6. Release machine from hook point while
refuelling.

sharpening instructions considerably
increases the risk of kickback.
CHAIN SHARPENING
The pitch of the chain is 3/8"x.050". Sharpen the
chain using protective gloves and a round file of
Ø 4 mm (5/32").
Always sharpen the cutters only with outward
strokes observing the values given in Fig. 23.
After sharpening, the cutting links must all have
the same width and length.
WARNING - A sharp chain produces well-
defined chips. When your chain starts to
produce sawdust, it is time to sharpen.
