7.2.3 Preparation and storage
of the fuel mixture
To prepare the fuel mixture:
– Place about half the amount of
petrol in an approved container.
– Add all the oil.
– Add the rest of the petrol.
– Close the cap and shake well.
IMPORTANT The fuel mixture tends to age.
Do not prepare excessive amounts of the fuel
mixture to avoid the formation of deposits.
IMPORTANT Keep the petrol and
fuel mixture containers separate and
easily identifiable to avoid the mistake
of using one in place of the other.
IMPORTANT Periodically clean the petrol and
fuel mixture containers to remove any deposits.
7.3 REFUELLING
Before refuelling:
• Shake the fuel mixture container well.
• Place the machine in a flat stable
position with the fuel mixture tank
upwards (fig. 10.G; fig. 11.G).
NOTE The cap of the mixture tank (fig. 10.G;
fig. 11.G) displays the following symbol:
Fuel mixture tank
• Clean the fuel tank cap and the
surrounding area to prevent any dirt from
entering the tank during refuelling.
• Open the fuel tank cap carefully to allow the
pressure inside to decrease gradually.
• Use a funnel to refill and avoid
filling the tank to the brim.
7.4
CLEANING THE MACHINE
AND THE ENGINE
Always clean the machine after use.
• To reduce fire hazards:
– keep the machine and, in particular,
the engine free of grass, leaves,
or excessive grease;
– periodically clean the cylinder fins
with compressed air and clear the
silencer area to get rid of sawdust,
branches, leaves or other debris;
• To avoid overheating and damage to the
engine, always keep the cooling air vents
clean and free of sawdust and debris.
7.5 CLEANING THE AIR FILTER
IMPORTANT Cleaning the air filter is
essential to guarantee the efficiency and
durability of the machine. Do not work with
a damaged filter or without a filter, as this
could permanently damage the engine.
It must be cleaned after every 15 working hours.
Clean the filter as follows:
• Loosen the knob (fig. 18.B), remove the cover
(fig. 18.A) and the filter element (fig. 18.C).
• Wash the filter element (fig. 18.C) with soap
and water. Do not use petrol or other solvents.
• Leave the filter to dry in the open air.
• Fit the filter element (fig. 18.C) and the
cover (fig. 18.A), back on, tightening
the knob (fig. 18.B) again.
7.6
SPARK PLUG
Periodically remove and clean the
spark plug using a metal brush (fig.
19) to get rid of any deposits.
Check and reset the correct distance
between the electrodes (fig. 19).
Replace the spark plug and fasten it
firmly using the supplied wrench.
The spark plug must be replaced with one
with the same characteristics whenever the
electrodes have burnt or the insulation has worn,
and in any case every 100 working hours.
7.7
ANGLE TRANSMISSION
Lubricate with lithium-based grease.
Remove the screw (fig. 20.A) and put in the
grease, turning the shaft manually until grease
emerges, then replace the screw (fig. 20.A).
7.8 NUTS AND BOLTS
• Keep all nuts, bolts and screws tight to be sure
the machine is in a safe working condition.
• Check regularly that the
handles are fixed firmly.
