AIR FILTER
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 8-10 working hours.
Clean the filter as follows (Fig. 9):
Loosen the knob (1), remove the cover (2) and the
ƒ
filter element (3).
Wash the filter element (3) with soap and water.
ƒ
Do not use petrol or other solvents.
Leave the filter to dry in the open air.
ƒ
Replace the filter element (3) and the cover (2) and
ƒ
tighten the knob (1).
CHECKING THE SPARK PLUG
Periodically remove and clean the spark plug (Fig.
10) using 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 re-
placed with one with the same characteristics
whenever the electrodes have burnt or the insu-
lation has worn, and in any case every 50 working
hours.
LONG PERIODS OF DISUSE
IMPORTANT If the machine will not be used for a
period of more than 2-3 months it is recommend-
ed to follow some advice to avoid difficulty when
you wish to use the machine and to prevent per-
manent damage to the engine.
STORAGE
Before putting the machine away:
Empty the fuel tank.
ƒ
Start the engine and run it idle until it comes to a
ƒ
halt, so that it uses up all the fuel that is left in the
carburettor.
Allow the engine to cool down and remove the
ƒ
spark plug cap.
