8.4 SPARK PLUG
Periodically remove and clean the
spark plug using a metal brush (Fig.

Check and reset the correct distance
between the electrodes (Fig. 22).
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
electrodes have burnt or the insulation has worn,
and in any case every 100 working hours.
8.5 CUTTING MEANS MAINTENANCE
When servicing the cutting means, bear in
mind that, even though the spark plug cable is
disconnected, the cutting means can still move.
Cutting means displaying the code
indicated on the Technical Data table
should 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 cap has been removed and
the cutting means is completely stationary.
Wear protective gloves.
8.5.1 Blade sharpening/balancing
For safety reasons, sharpening
and balancing should be done by a
Specialised 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 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, thus
it must only be used from 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 chapter 4.3.
8.5.3 Replacing the cutting line head
Follow the sequence indicated in (F
ig. 24 - Type I, Fig. 25 Type II).

loosening the screws (Fig. 25.C).
• Remove the line cutting knife (Fig. 25.A) in
a vice and sharpen it using a flat file, being
careful to retain the original cutting angle.
• Refit the line cutting knife (Fig.
25.A) on the guard (Fig. 25.B).
8.7 TUNING MINIMUM SPEED
If the cutting means moves when the
engine is running idle, contact your dealer
to have the engine adjusted correctly.
8.8 CARBURETTOR
The carburettor is tuned by the manufacturer
to achieve maximum performance in all
situations, with a minimum emission of toxic gas
in compliance with the regulations in force.
In the event of poor performance, contact your
Dealer for a check of the carburation and engine.
