5. ROUTINE MAINTENANCE

Correct maintenance is essential to maintain
the original efficiency and safety of the machine
over time.
WARNING! During maintenance opera-
tions:
– R emove the spark plug cap.
– W ait until the engine is sufficiently cold.
– Never dispose of oils, fuel or other pollut-
ing materials in unauthorised places.
5.1 STORAGE
At the end of each working session, carefully
clean the machine of dust and debris, and make
sure that there are no damaged parts, replacing
any faulty parts. The machine must be stored in
a dry place away from the elements and with the
cover correctly fitted.
5.2 CLEANING THE ENGINE
AND THE SILENCER
To reduce fire risks, periodically clean the cylin-
der fins with compressed air and clear the silenc-
er area to get rid of sawdust, branches, leaves or
other debris.
5.3 STARTING UNIT
To avoid overheating and damage to the engine,
always keep the cooling air vents clean and free
of sawdust and debris.
If you notice signs of wear on the starter cable,
contact your Dealer for a replacement.
5.4 NUTS AND SCREWS
Periodically check that all the nuts and screws
are securely tightened and the handgrips are
tightly fastened.
5.5 CLEANING THE AIR FILTER (Fig. 11)
IMPORTANT Cleaning the air filter is essential to
guarantee the efficiency and duration of the ma-
chine. Do not work with a damaged filter or with-
out 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 (3), remove the cover (1) and
the filter element (2).
– Wash the filter element (2) with soap and wa-
ter. Do not use petrol or other solvents.
– Leave the filter to dry in the open air.
– Fit the filter element (2) and the cover (1) back
on, tightening the knob (3) again.
5.6 CHECKING THE SPARK PLUG ( (Fig. 12)
Periodically remove and clean the spark plug us-
ing a metal brush to get rid of any deposits.
Check and reset the correct distance between
the electrodes.
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 elec-
trodes have burnt or the insulation has worn, and
in any case every 100 working hours.
5.7 HEAD LINE REPLACEMENT (Fig. 13)
- Follow the sequence indicated in the figure.
5.8 SHARPENING THE LINE CUTTING
KNIFE (Fig. 14)
– Remove the line cutting knife (1) from the
guard (2) by unscrewing the screws (3).
– Fix the line cutting knife in a vice and sharpen
it using a flat file, being careful to retain the
original cutting angle.
– Refit the knife on the guard.
5.9 LONG PERIODS OF DISUSE
IMPORTANT If you are not going to use the ma-
chine for a period of more than 2-3 months, we
recommend you do a few things before putting it
away. This will make it easier when you want to
use the machine again and will also prevent per-
manent damage to the engine.
Before putting the machine away:
– Empty the fuel tank.
– Start the engine and run it idle until it comes to
