8. EXTRAORDINARY MAINTENANCE
8.1 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.
8.1.1 Sharpening 3-point blade
IMPORTANT For safety reasons, sharpening
and balancing should be done by a Specialised
Centre with suitable skills and equipment
for the job to avoid damage to the blade
that 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.
8.1.2 Replacing 3-point blade
The blade must never be repaired,
but must be replaced as soon as
signs of breaking are noted or the
sharpening limit is exceeded.
Blades displaying the code indicated
on the Technical Data table should
be used on this machine.
Given product evolution, the above
mentioned blades may be replaced in time
with others having similar interchangeability
and operating safety features.
8.2 REPLACING THE CUTTING
LINE HEAD
Follow the sequence indicated in fig. 21
8.3 SHARPENING THE LINE
CUTTING KNIFE
• Remove the line cutting knife (Fig.
22 A) from the guard (Fig. 22.B), by
loosening the screws (Fig. 22.C).
• Remove the line cutting knife (Fig. 22.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. 22
A) on the guard (Fig. 22.B).
8.4 TUNING MINIMUM SPEED
If the cutting means moves when the
engine is running idle, contact your dealer
to have the engine adjusted correctly.
8.5 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.
9. STORING THE MACHINE
IMPORTANT The safety regulations to
follow for putting into storage are described
in paragraph 2.4. Strictly comply with these
instructions to avoid serious risks or hazards.
If you are not going to use the machine
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 permanent damage to the engine.
Before putting the machine away:
1. Empty the fuel tank in the open air with
the engine switched off and cold.
2. Start the engine and run it idle until it
comes to a halt, so that it uses up all
the fuel that is left in the carburettor.
3. Wait for the engine to cool.
4. Remove the spark plug cap
(fig. 10.H; fig. 11.H)
5. Clean the machine thoroughly.
6. Check the machine for any
damage. If necessary, contact the
authorised assistance centre.
7. Store the machine:
– in a dry place
– protected from inclement weather
– with the blade guard fitted correctly
– in a place where children cannot get to it
– making sure that keys or tools used
for maintenance are removed.
When you wish to start using the
machine again, prepare it as indicated
in chapter "6. Using the machine" .
