Operation Manual

Correct maintenance is essential to maintain the
original eciency and safety of the machine over
time.
WARNING!
During maintenance ope-
ra tions:
– Remove the spark plug cap.
– Wait until the engine is suciently cold.
– Use protective gloves when handling the
blades.
– Keep the blade protection device on, except
when intervening directly on the blade.
– Never dispose of oils, fuel or other polluting
materials in unauthorised places.
CYLINDER AND SILENCER
To reduce re risks, periodically clean the cylinder
aps with compressed air and clear the silencer
area to get rid of sawdust, branches, leaves or
other debris.
STARTING SYSTEM
To avoid overheating and damage to the engine,
always keep the cooling air vents clean and free
of sawdust and debris.
The starter rope must be replaced as soon as it
shows signs of wear.
NUTS AND SCREWS
Periodically check that all the nuts and screws are
securely tightened and the handgrips are tightly
fastened.
CLEANING THE AIR FILTER (Fig. 17)
IMPORTANT
Cleaning the air lter is es-
sential to guarantee the eciency and duration of
the machine. Do not work with a damaged lter or
without a lter, as this could permanently damage
the engine.
It must be cleaned after every 15 working hours.
Clean the lter as follows:
– Press the button (1), turn the cover (2) over and
remove the lter element (3).
– Wash the lter element (3) with soap and wa ter.
Do not use petrol or other solvents.
– Leave the lter to dry in the open air.
– Ret the lter element (3) and close the cover (2)
pushing until it clicks into place.
CHECKING THE SPARK PLUG (Fig. 18)
Periodically remove and clean the spark plug us-
ing a metal brush to get rid of any deposits.
Check and reset the correct distance between the
electrodes.
Replace the spark plug and fasten it rmly using
the supplied wrench.
The spark plug must be replaced with one with
the same characteristics whenever the electrodes
have burnt or the insulation has worn, and in any
case every 100 working hours.
TUNING THE CARBURETTOR
The carburettor is tuned by the manufacturer to
achieve maximum performance in all situations,
with a minimum emission of toxic gas in compli-
ance with the regulations in force.
In the case of poor performance contact your
Dealer for a check of the carburetion and engine.
• Tuning minimum speed
WARNING!
The cutting device must
not move when the engine is running idle. If
the cutting device moves when the engine is
running idle, contact your dealer to correctly
regulate the engine.
ANGLE TRANSMISSION (Fig. 19)
Lubricate with lithium-based grease.
Remove the screw (1) and put in the grease, turn-
ing the shaft manually until grease emerges, then
replace the screw (1).
SHARPENING THE 3 or 4 POINT BLADE
(Fig. 20)
WARNING!
Use protective gloves. If
sharpening is done without removing the
blade, disconnect the spark plug cap.
Sharpening must be done taking account of the
type of blade and cutting edges, using a at le
and working all the points equally.
