CHECKING THE MACHINE
Before start ng work please:
– check that all the screws on the mach ne and the
cutt ng dev ce are t ghtly fastened;
– check that the a r f lter s clean;
– check that the protect on dev ces are well fas-
tened and work ng eff c ently;
– check the handgr ps are well fastened.
PREPARING THE FUEL
Th s mach ne s f tted w th a two-stroke eng ne
wh ch requ res a m xture of petrol and lubr cat ng
o l.
Using petrol alone will dama-
ge the motor and will ca se for invalidation of the
warranty.
Only se q ality f els and
oils to maintain high performance and g arantee
the d ration of the mechanical parts over time.
• P trol charact ristics
Only use unleaded petrol w th a fuel grade of at
least 90 N.O.
Unleaded petrol tends to cre-
ate deposits in the container if preserved for more
than 2 months. Always se fresh petrol!
• Oil charact ristics
Only use top qual ty synthet c o l spec f cally for
two-stroke eng nes.
Your dealer can prov de you w th o ls wh ch have
been spec f cally developed for th s type of eng ne,
and wh ch are capable of guarantee ng a h gh level
of protect on.
The use of these o ls makes t poss ble to prepare
a 2% m xture, cons st ng n 1 part o l to 50 parts
petrol.
IMPORTANT
IMPORTANT
IMPORTANT
• Pr paration and pr s rvation
of th fu l mixtur
Petrol and the fuel ixture are highly infla -
able!
– Keep the petrol and fuel ixture in ho olo-
gated fuel containers, in safe place, away
fro any fla es or heat sources.
– Never leave the containers within the reach
of children.
– Never s oke whilst preparing the ixture
and avoid inhaling the petrol fu es.
The chart nd cates the amount of petrol and o l to
use to prepare the fuel m xture accord ng to the
type of o l used.
To prepare the fuel m xture:
– Place about half the amount of petrol n a ho-
mologated tank.
– Add all the o l, accord ng to the chart.
– Add the rest of the petrol.
– Close the top and shake well.
The f el mixt re tends to
age. Do not prepare excessive amo nts of the f el
mixt re to avoid deposits from forming.
Keep the petrol and f el mix-
t re containers separate and easily identifiable to
avoid the mistake of sing one in place of the other.
Periodically clean the petrol
and f el mixt re containers to remove any event al
deposits.

low the rod to be properly cooled.
Do not use the achine for
sweeping, tilting the cutting line head. The power
of the engine could throw objects and s all
stones 15 etres or ore, causing da age and
injuries to people.
