Note: The life span of the chain and bar guides
depends on the quality of the oil used. Do not use old
or already used oil! Only use oil that does not damage
your surroundings. Only store oil in homologated
recipients.
6.3.3. FIXING THE CABLE
Only use prolongators certified for outdoor use. The
cable section must be at least 1.5 mm
must have a maximum length of 25 m and it must
be completely unrolled before starting to work with
the machine. Fix the cable by inserting it on the hook
provided to this
effect at the back
of the machine.
Prolongators longer
than 25 m will
reduce the working
efficiency of the
machine.
6.3.4. TENSING THE CHAIN
Always remove the cable from the mains prior to doing
any maintenance or check up work on the machine.
To avoid injuries when checking the chain, wear
security gloves when mounting, tensing or checking
the chain.
Tensing the chain:
screw clockwise to tense the chain and anticlockwise
to untense the chain until the chain tension is
adequate.

4. Tighten the nut of the chain cover. Do not tense the
chain too much.
NOTES:
The chain dilates with heat. When the chain is cold
the tension will be more than whe hot. If you tense the
chain when cold, you will have to check the tension
after just a few cuts (the chain will have reached its
working temperature) as it will have expanded when
it heats up and will loosen itself and it could come
out from the bar chain guide. Retense the chain if
necessary.
If the chain is tensed again when hot, you must check
the chain tension when you have finished work as
when the chain cools down it will tend to tense and if
