– Clean the fuel tank cap and the surrounding
area to avoid any dirt fromentering the tank
during refilling.
– Carefully open the fuel tank cap to allow the
pressure inside to decrease gradually. Use a
funnel to refill and avoid filling the tank to the
brim.
CAUTION!
Always close the fuel tank cap firmly.
CAUTION!
Immediately clean all traces of fuel
which may have dripped on the ma-
chine or the ground and do not start
the engine until the petrol fumes have
dissipated.
3. CHAIN LUBRICANT
Only use special oil for chainsaws or ad-
hesive oil for chain saws. Do not use
oilcontaining impurities so as not to block
the oil filter and to prevent irreparable da-
mage to the oil pump.
The special oil for lubricating the chain
is biodegradable. Use of a mineral oil or
engine oil causes serious damage to the
environment.
It is essential that you use good quality oil to lub-
ricate the cutting parts effectively. Used or poor
quality oil does not guarantee good lubrication
and reduces the service life of the chain and bar.
It is always worth topping up the oil tank comple-
tely (using a funnel) every time you refuel. Since
the oil tank capacity is enough to guarantee that
the fuel runs out first, you will avoid the risk of ope-
rating the machine without lubricant.
4. CHECKING THE MACHINE
Before starting work please:
– fill the relevant tanks with fuel and oil;
– check that all the screws on the machine and
the bar are tightly fastened;

– check that the chain brake is working effici-
ently;
– check the chain tension.
5. CHECKING THE CHAIN TENSION
– Loosen the cover nuts, using the supplied
wrench (Fig. 6).
– Turn the chain tension adjuster screw (6) to
adjust the chain tension (Fig. 5).
– Raise the bar and tighten the guard nuts se-
curely using the wrench (Fig. 6).
6. CHECKING THE CHAIN BRAKE
This machine is equipped with a safety brake sys-
tem.
In the event of a kickback while working following
an irregular contact of the tip of the bar, with a
brusque upward movement that causes the hand
to strike the front guard. In this case, the brake
blocks the chain movement and must be released
manually in order to disengage it.
This brake can be operated manually by pushing
the front guard forward. To release the brake, pull
the front guard towards the handgrip until you
hear a click.
To check that the brake works efficiently, proceed
as follows:
– Make sure you are holding the machine firmly
with both hands when you start the engine.
– Use the accelerator lever to keep the
chainmoving, push the brake lever forwards
using the back of your left hand; the chain
must stop immediately.
– When the chain has stopped, immediately re-
lease the accelerator lever.
– Release the brake.
CAUTION!
Do not use the machine if the chain
brake does not function correctly and
have it inspected by your dealer.
