Chain maintenance table
WARNING!
The specifications of the chain and the bar homologated for this machine
are shown in the “EC Conformity Statement” provided. Do not use other types of chains or bars
for safety reasons.
The table gives the sharpening data for different types of chains, but this does not mean you
can use different chains from the homologated one.
When performance is poor, first check that the
chain runs smoothly and the bar rails are not dis
-
torted, then contact your dealer to check the car

• Vibrations increase.
• Fuel consumption increases.
WARNING!
If the chain is not suffi

creases.
A specialized centre will sharpen the chain using
the right tools to ensure minimum removal of mate-
rial and even sharpness on all the cutting edges.
