IMPORTANT Keep containers of fuel blend
and petrol separate and clearly identified to
avoid swapping them at the time of use.
IMPORTANT Clean the petrol
and fuel blend containers at regular
intervals to remove any deposits.

7.3 REFUELLING

Before refuelling:
1. vigorously shake the canister
containing the fuel blend;
2. place the machine on a level surface
in a stable position with the fuel tank
cap facing upwards (Fig. 11.G).
NOTE The fuel tank
(Fig. 11.G) has the following symbol:
Fuel blend tank.
3. Clean the fuel cap and the surrounding area
to avoid ingress of dirt when refuelling.
4. Carefully open the fuel tank slowly to allow
the pressure to decrease gradually.
5. Refuel using a funnel; do not fill
the tank right to the top.
7.4 CLEANING THE MACHINE
AND THE ENGINE
Always clean the machine after use.
To reduce the risk of fire:
– keep the machine and especially the
engine free from residues of grass,
leaves or excessive grease;
– frequently clean the cylinder fins
with compressed air and eliminate
sawdust, twigs, leaves or other
debris from the silencer area.
To avoid overheating and damage to the
engine, always keep the cooling air vents
clean and free of sawdust or debris.

7.5 NUTS AND BOLTS

• Keep all nuts, bolts and screws tight to be sure
the equipment is in safe working condition.
• Check regularly that the
handles are fixed firmly.

8. OCCASIONAL MAINTENANCE

8.1 ANGLE TRANSMISSION
LUBRICATION:
Lubricate with lithium based grease.
Remove the screw (Fig. 20.A) and insert the
grease by rotating the shaft by hand until the
grease comes out; then refit the screw (Fig. 20.A).

8.2 CLEANING THE AIR FILTER

IMPORTANT Cleaning the air filter is
essential for correct operation and durability
of the machine. NEVER work without a filter
or with a damaged filter to avoid causing
irreparable damage to the engine.
Cleaning must be performed
every 15 hours of work.
To clean the filter:
1. unscrew the screws (Fig. 21.B),
remove the cover (Fig. 21.A) and
remove the filter element (Fig.21.C);
2. blow compressed air from the inside to
remove dust and debris (Fig. 22 C).
3. refit the filer element (Fig. 21.C)
and the cover (Fig. 21.A); then
tighten the screws (Fig.21.B);

8.3 SPARK PLUG

Remove and clean the spark plug at
regular intervals; remove any deposits
with a wire brush (Fig. 23).
Check and reset the correct gap
between the electrodes (Fig. 23).
Refit the spark plug and tighten it
fully using the wrench supplied.
The spark plug must be replaced with
one having similar characteristics if burnt
electrodes or deteriorated insulation are
found or after every 100 hours of operation.
