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.

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.
