8.4 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.
8.4.1 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.

8.4.2 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.
8.4.3 Replacing the cutting line head
• Type I
Follow the sequence shown in (Fig. 25).
• Type II
Cut the new line to the indicated
length (Fig. 26.A).
4. Rotate the winding knob (Fig. 27.A)
to align the reference on the knob
(Fig. 27.B) with the reference on
the head body (Fig. 27.C).
5. Insert one end of the line (Fig. 27.D) in
one of the two output holes and pass
the line through the opposite hole.
6. Align the lines that exit the
two holes evenly.
7. Rotate the winding knob (Fig. 28.A)
following the direction of the arrows to
