WARNING – Mufflers with catalytic
converters become very hot during
operation, and retain heat for a long time
after the engine has been stopped. This is the
case even with the engine idling. Contact can
burn the skin. Always remember the potential
fire risk!
CAUTION – If the muffler is damaged, it
must be replaced. If the muffler frequently
becomes blocked, this could be an indication that
the efficiency of the catalytic converter is limited.
WARNING – Do not operate your machine
if the muffler is damaged, missing or
modified. Operating the machine with an
improperly maintained muffler will increase
the risk of fire and hearing loss.
EXTRA MAINTANANCE ADVISABLE
It is advisable to inspect the machine by a
specialized technician at an authorized service
network at the end of season, if used intensively,
and every two years if with normal use.
ATTENTION: All maintenance operations
not reported in this manual must be carried
out by an authorized Service Center. To ensure
steady and regular blower operation, remember
that parts must only be replaced with ORIGINAL
SPARES.
Any unauthorized changes and/or use of
non-original replacement parts may result in
serious injury or death to the operator or third
parties.
9. TRANSPORTATION
Only transport the blower with the engine
switched off.
WARNING - When transporting the machine
on a vehicle, ensure that it is firmly and securely
fastened using straps or belts. The machine must
be transported in the vertical position with an
empty tank, also ensuring compliance with
applicable transport regulations for such
machines.
SAFETY GUARD
Check that the spring (D, Fig.13) and the
catch (E) are in perfect working order. These
components ensure that the safety guard is
properly closed.
Following prolonged use of the blower a large
amount of dust may be deposited on the fan
casing. This obstructs the air flow (reduced
volume) and can result in damage to the fan and/
or overheating of the engine. For this reason, be
sure to clean the fan casing regularly.
STARTER ASSEMBLY
WARNING: The coil spring is tensioned
and could fly out if released, causing
s e r i o u s i n j u r y. N e ve r at te m p t to
disassemble or modify the spring.
CARBURETOR
The carburettor is factory adjusted to standard
settings that comply with emissions regulations.
WARNING:
- Do not change the carburettor settings
by tightening or loosening the regulator
screws; this operation must be performed
by qualified personnel at an Authorized
Service Centre.
- Incorrect adjustment of the carburettor can
cause serious damage to the engine.
- Furthermore, do not tamper with or
remove the red protective caps on the
carburettor regulator screws.
In the case of problems (engine dies when
idling, irregular engine speed or failure to reach
maximum power) seek the assistance of an
Authorized Service Centre.
WARNING: Weather conditions and
altitude may affect carburation.
MUFFLER
WARNING – This muffler incorporates
a catalytic converter, needed in order
to ensure the engine complies with current
emissions standards. Never attempt to modify or
remove the catalytic converter: in doing so, you
will be breaking the law.
