8.3 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.
• Type I
To clean the filter:
1. unscrew the screws (Fig. 29.B), remove
the cover (Fig. 29.A) and remove the filter
element (Fig.29.C);
2. blow compressed air from the inside to
remove dust and debris (Fig. 30)
3. refit the filter element (Fig. 29.C) and the
cover (Fig. 29.A); then tighten the screws
(Fig.29.B);.
• Type II
To clean the filter:
1. unscrew the knob (Fig. 29.B), remove the

8.4 SPARK PLUG

Remove and clean the spark plug at regular
intervals; remove any deposits with a wire brush
(Fig. 31).
Check and reset the correct gap between the
electrodes (Fig. 31).
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.
8.5 CUTTING MEANS MAINTENANCE
When servicing the cutting means, bear in mind
that it can still move even if the spark plug cable
been disconnected.
Cutting means displaying the code indicated on
the Technical Data table should only be used on
this machine.
Given product evolution, the cutting means
mentioned in the "Technical Data" table may
be replaced in time with others having similar
interchangeable and operating safety features.
Do not touch the cutting means until the
spark plug cable has been disconnected and
the cutting means is completely stationary.
Wear protective gloves.
8.5.1 Blade sharpening/balancing
For safety reasons, sharpening and
balancing should be performed by an
Authorised Service Centre with suitable skills
and equipment for the job; without risking
any damage to the blade which would make
it unsafe when used.
3 point, 4 point and 8 point blades can be used on
both sides. When one side of the points is worn,
the blade can be turned and the other side used.
When both sides of the points are worn, have
them sharpened.
The saw blade is not reversible and
therefore should only be used on one side.

8.5.2 Blade replacement

The blade must never be repaired,
but must be replaced as soon as signs of
breaking are noted or the sharpening limit is
exceeded.
For replacement procedures, see sections 4.5.3
and 4.5.4.
