3. insert the battery in its housing fitted on the
machine (Fig. 19.B) or in one of the housings
of thebattery backpack (Fig. 6) (if provided);
4. push down the battery all the way until
you hear a " click" that locks it in place
and guarantees the electrical contact;
7.3 CLEANING THE MACHINE
After every work session, clean the machine
thoroughly to remove all dust and debris.
• To reduce fire hazards, keep the machine
and, in particular, the motor free of
leaves, branches or excessive grease.
• Always clean the machine after use with a
damp cloth dipped in neutral detergent.
• Remove all traces of humidity using
a soft damp cloth. Humidity can
generate risks of electric shocks.
• Do not use aggressive detergents or solvents
to clean the plastic parts or hand grips.
• Do not spray water onto the motor
and electrical components and
prevent them from getting wet.
• To avoid overheating and damage to the
motor or the battery, always keep the
cooling air vents clean and free of debris.
7.4 CLEANING AND LUBRICATION
OF THE CUTTING MEANS
To increase the efficiency and working life
of the blades, clean and lubricate them
carefully after each work session:
Do not touch the cutting means until
the battery has been removed and the
cutting means is completely stationary.
• Place the machine in a stable
horizontal position on the ground.
• Use a soft cloth to clean the blades, along with
a brush to remove more difficult dirt and debris.
• Lubricate the blades by applying a light layer
of specific oil, preferably the non-pollutant
type, along the upper edge of the blade.
7.5 NUTS AND BOLTS
• Keep all nuts, bolts and screws tight to be sure
the equipment is in safe working condition.
• Check regularly that the
handles are fixed firmly.
8. OCCASIONAL MAINTENANCE
8.1 CUTTING MEANS OCCASIONAL
MAINTENANCE
Do not touch the cutting means until
the battery has been removed and the
cutting means is completely stationary.
If the blades are used correctly, following all the
instructions provided, they will not require any
maintenance work and will not need sharpening.
8.1.1 Checks
Periodically check that the blades are
not bent, damaged or deformed and that
the screws are adequately tightened.
Adjustment of the distance between
blades is not necessary, as this is
predetermined by the manufacturer.
8.1.2 Sharpening
It is necessary to sharpen the blades when
the trimming performance decreases and
the branches tend to stick together.
For safety reasons, sharpening should
be done by an Authorised Centre with
suitable skills and equipment for the job;
without risking any damage to the blade
which would make it unsafe when used.
Always replace and never repair a
blade which has blunt cutting edges.
8.1.3 Replacement
The blade must never be repaired,
but must be replaced as soon as
signs of breaking are noted or the
sharpening limit is exceeded. For
safety reasons replacements should be
performed by an Authorised Centre.
Blades displaying the code indicated
on the Technical Data table should
be used on this machine.
Given product evolution, the blades listed
in the "Technical Data" table may be
replaced in time with others having similar
interchangeable and operating safety features.
