PREPARING TO WORK
Before refuelling:
– Shake the fuel mixture container well.
– Place the machine on a flat stable surface, with
the fuel tank cap facing upwards.
– Clean the fuel tank cap and the surrounding area
to avoid any dirt from entering the tank during re-
filling.
– 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.
WARNING!
cap firmly.
WARNING!
ces of fuel which may have dripped on the
machine or the ground and do not start the en-
gine until the petrol fumes have dissipated.
3. CHAIN LUBRICANT
IMPORTANT
saws or adhesive oil for chain saws. Do not use oil
containing impurities so as not to block the oil filter
and to prevent irreparable damage to the oil pump.
IMPORTANT
ing the chain is biodegradable. Use of a mineral oil
or engine oil causes serious damage to the envi-
ronment.
It is essential that you use good quality oil to lubri-
cate the cutting parts effectively. Used or poor
quality oil does not guarantee good lubrication and
reduces the duration of the chain and bar.
It is always worth topping up the oil tank complete-
ly (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 operat-
ing 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;
Always close the fuel tank
Immediately clean all tra-

clean and dry, correctly mounted and well fas-
tened to the machine;

WARNING!
with the engine off.
– Loosen the cover nuts, using the supplied
wrench (Fig. 6).
– Turn the chain tension adjuster screw (6) to ad-
just 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 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 level to keep the chain mov-
ing, push the brake lever forwards using the
back of you left hand; the chain must stop im-
mediately.
– When the chain has stopped, immediately re-
lease the accelerator lever.
– Release the brake.
WARNING!
the chain brake does not function correctly
and have it inspected by your dealer.
