AIR FILTER
Every 8-10 working hours, remove the cover (A,
Fig. 11), clean the filter (B).
GB
Clean with Emak degreaser p/n 001101009A. Blow
with compressed air, at a distance.
Replace if dirty or damaged. The engine runs
irregularly if the filter is clogged, with consequent
higher consumption and lower performance.
FUEL TANK
Check fuel filter periodically. A dirty filter can cause
difficult starting and lower engine performance.
To clean filter proceed as follows: remove it from
fuel filling hole. Replace it (Fig. 10) if too dirty.
ENGINE
Clean cylinder fins with a brush or compressed
air periodically. Dangerous overheating of engine
may occur due to impurities on the cylinder.
SPARK PLUG
Clean spark plug and check electrode distance
periodically (Fig. 12). Use Champion NGK CMR7A
or of other brand with the same thermal grade.
ATTACHMENTS COUPLING
To ensure constant and correct operation of the
tool, every 30 hours of operation remove the
attachment (D, Fig. 4), grease the drive shaft
inside the coupling (E, Fig. 4) and the drive shaft
at the end of the attachment (D, Fig. 4). Use
high quality molybdenum disulphide grease.
Always grease the coupling whenever you
change the attachment.
CARBURETOR
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 quarter round
the hall range admissible is determined by the
manufacturer and you can not modify it.

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
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 machine
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 machine operation,
remember that parts must only be replaced with
ORIGINAL SPARES.
