6.2 CARBURETTOR ADJUSTMENTS

achieve maximum performance in all situations,
with a minimum emission of toxic gas in compli-
ance with the regulations in force.
In the case of poor performance contact your
Dealer for a check of the carburation and engine.
6.3 SHARPENING THE SAW BLADE
WARNING! For safety reasons, sharp-
ening 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 un-
safe when used.
WARNING! The saw blade is not revers-
ible, thus it must only be used from one side.
The blade must never be repaired, but must be
replaced as soon as signs of breaking are noted
or the sharpening limit is exceeded.
