Operation Manual

Chain maintenance table
WARNING!
The specications 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 dierent types of chains, but this does not mean you
can use dierent chains from the homologated one.
When performance is poor, rst check that the
chain runs smoothly and the bar rails are not dis-
torted, then contact your dealer to check the car-
buretion and the engine.
• Tuning minimum speed
WARNING!
The chain must not move
when the engine is running idle. If the chain
moves when the engine is running idle, con-
tact your dealer to correctly regulate the en-
gine.
SHARPENING THE CHAIN
WARNING!
To ensure that the chain-
saw works safely and eciently, it is essential
that the cutting components are well-sharp-
ened.
Sharpening is necessary when:
• The sawdust looks like dust.
• Cutting becomes more dicult.
• The cut is not straight.
• Vibrations increase.
• Fuel consumption increases.
WARNING!
If the chain is not su-
ciently sharpened, the kick-back’s risk in-
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.
To clean the lter:
– Unscrew the knob (1).
– Remove the lid (2) and the lter element (3).
– Gently tap the lter element (3) to remove the
dirt and, if necessary, clean it with low pressure
compressed air.
IMPORTANT
The lter element (3) must
never be washed and must be replaced if it is too
dirty or damaged.
– Reassemble the lter element (3) and the lid (2).
– Screw the knob (1) back on.
CHECKING THE SPARK PLUG (Fig. 23)
The spark plug can be accessed by removing the
air lter cover.
Periodically remove and clean the spark plug us-
ing a metal brush to get rid of any deposits.
Check and reset the correct distance between the
electrodes.
Replace the spark plug and fasten it rmly 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.
TUNING THE CARBURETTOR
The carburettor is tuned by the manufacturer to
achieve maximum performance in all situations,
with a minimum emission of toxic gas in compli-
ance with the regulations in force.
