of the catalytic converter is impaired.

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.

- Clean the brush cutter completely and lubricate

the metallic parts.

- Remove, clean and lubricate the blade to

prevent rusting.

- Remove the blade fixing flanges, clean, dry

and lubricate the bevel gear seat.

- Empty the fuel tank and put the cap back on.
- Thoroughly clean the cooling slots and the air

filter (Fig. 23).

- Store the brush cutter in a dry place, preferably

(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 catalyst is damaged it

should be replaced

. If the catalyst frequently

blocked, this can be a sign that the performance
