operating the machine without lubricant.
7.5 CLEANING THE MACHINE
AND THE ENGINE
After every work session, clean the machine
thoroughly to remove all dust and debris.
• To reduce fire hazards:
– keep the machine and, in particular, the
engine and muffler zone free of sawdust,
branches, leaves, or excessive grease;
– use compressed air to clean the
cylinder fins on a regular basis.
• To avoid overheating and
damage to the engine:
– the cooling air circulation vents (Fig.
27) must always be kept clean and
free of sawdust and debris.
• Keep the clutch bell free of sawdust
and debris (Fig. 28) removing the clutch
cover (par. 4.3) and replacing it correctly
on completing the operation.
Have your dealer check the greasing of the
internal bearing approximately every 30 hours.
7.6 CLEANING THE CHAIN
Remove any traces of sawdust or oil deposits
from the chain every time it is used.
If there is excessive dirt or resin build-up,
disassemble the chain and place it in a
container with a specific cleanser for a few
hours. Then rinse with clean water and
treat with a suitable anticorrosive spray,
before reassembling on the machine.
7.7 CHAIN CATCHER
Check the chain stop pin conditions before each
use (Fig. 1.H) and repair in the event of damages.
7.8 MACHINE AND BAR

7.9 NUTS AND BOLTS
• Before use, always check that all nuts and
bolts are securely tightened to be sure the
machine is in safe working condition.
• Before use, always check that the hand
grips are firmly fastened in place.
8. EXTRAORDINARY MAINTENANCE
8.1 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. The filter element must
always be replaced if it is too dirty or damaged.
It must be cleaned after every
8-10 working hours.
Clean the filter as follows:
1. Unscrew the knob (Fig. 30.A) and
remove the cover (Fig. 30.B);
2. Remove the upper part of the filter
(Fig. 31.A) from the lower part (Fig.
31.B) using a screwdriver.
3. Tap the upper part gently to remove
the dirt and clean using a soft brush.
4. If it is completely clogged, wash with
clean petrol. If you are used compressed
air, aim the jet so that it blows from the
inside towards the outside (Fig. 32).
5. Replace the upper part of the air
filter by pressing on the edges until
you hear it click into place.
6. Remount the cover.
7. Screw the knob back on.
8.2 CHAIN BRAKE METAL BAND
Have your dealer check the condition
of the metal band (Fig. 33.A) around
the clutch housing once a month.
The band must be replaced if
deteriorated or deformed.
8.3 CHAIN DRIVE SPROCKET
Regularly check the condition of the
sprocket (Fig 6.B)with your local dealer or
Authorised Service Centre and replace it
when wear exceeds the accepted limits.
Do not mount a new chain with
a worn sprocket or vice-versa.
8.4 CHECKING THE SPARK PLUG
The spark plug can be found on the
bottom of the machine (Fig. 34).
