the tool, every 30 hours of operation remove
the attachment (D, Fig. 5A), grease the drive
shaft inside the coupling (E, Fig. 5A) and the
drive shaft at the end of the attachment (D, Fig.
5A). Use high quality molybdenum disulphide
grease. Always grease the coupling whenever
you change the attachment.
CARBURETOR
Before adjusting the carburetor, clean the air filter
(C, Fig. 23) and warm up the engine. This engine
is designed and manufactured in order to comply
with the applicable 97/68/EC, 2002/88/EC and
2004/26/EC Directive. The carburetor (Fig. 21)
is designed to permit only the adjustement
of L and H screws in a range of 1/4; the quarter
round the hall range admissible for L and H ± 1/8
screws is determined by the manufacturer and
you can not modify it.
WARNING: Don't try to force the screws
outside the range!
Idle screw T is adjusted in order to ensure a good
safety margin between idle running and clutch
engagement.
Screw L must be adjusted so that the engine
promptly responds to sharp accelerations and
gives good idle operation.
Screw H must be adjusted so that the engine gives
maximum power during the cutting phase.
WARNING: With the engine idling (2800-
3000 rpm), the blade should not rotate. We
recommend that you have your nearest
authorised dealer or service workshop carry
out any carburettor adjustments.
WARNING: Weather conditions and
altitude may affect carburation.
MUFFLER (BC 220 - BC 240)
WARNING! - This muffler is fitted with a
catalytic converter needed for the engine to be in
compliance with the emissions requirements.
Never modify or remove the catalytic converter:
failure to do so is a violation of law.
WARNING! - Mufflers fitted with catalytic
converters get very hot during use and remain
so for some time after stopping. This also
applies at idle speed. Contact can result in burns
to the skin. Remember the risk of fire!
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 brush
cutter if the muffler is damaged, missing or
modified. 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 brush cutter
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.

10. STORAGE

If the machine is to be stored for long periods:
- Drain and clean the fuel tank in a well-ventilated
area. To drain the tank, start the engine and
wait until the fuel is exhausted and the engine
stops (leaving fuel mixture in the carburettor
could damage the membranes).
- The procedures for returning the machine to
service following winter storage are the same as
for starting up during everyday use (page 28).
- Follow all the maintenance regulations
previously described.
