WARNING! – Always wear protective
gloves during maintenance operations. Do not
carry out maintenance with the engine hot.
Never use fuel for cleaning operations.
AIR FILTER
Every 8-10 working hours, remove the cover (A,
Fig. 22), clean the filter (B).
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 FILTER
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. 21) 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. 23). Use Champion NGK BPMR8Y
or of other brand with the same thermal grade.
GEAR HOUSING
Every 30 working hours, remove screw (D, Fig. 8)
on the gear housing and check the quantity of
grease. Do not use more than 10 grams. Use high
quality molybdenum bisulfide grease.
TRASMISSION
Grease the joints of the flexible (B, Fig.25) every
20 working hours with molybdenum disulfide.
Grease the joints of the rigid tube (D, Fig. 25) every
30 working hours with molybdenum disulfide.
CARBURETOR
Before adjusting the carburetor, clean the air filter
(B, Fig. 22) and warm up the engine. This engine
is designed and manufactured in order to comply
with the applicable (EU) 2016/1628 Regulations.
Idle screw T (Fig. 20) is adjusted in order to ensure
a good safety margin between idle running and
clutch engagement.
WARNING: Don't tamper the carburetor.
WARNING: With the engine idling (2800
rpm), the blade should not
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 brush
cutter if the muffler is damaged, missing or
modified. An improperly maintained muffler
will increase the risk of fire and hearing loss.
