IMPORTANT In order not to compromise
the efficiency of the electromagnetic clutch:
- do not let the clutch come into contact with oil;
- do not spray pressurised water
directly on the clutch unit;
- do not clean the clutch with petrol.
b. Cleaning the exterior
Do not let debris and dried grass
accumulate in the upper part of the
cutting-means assembly in order
to maintain maximum machine
efficiency and safety levels.
To clean the upper part of the
cutting-means assembly:
• lower the cutting-means assembly
completely (position «1»);
• blow a jet of compressed air through the right
and left guard openings (fig. 29; fig. 30).
7.6 BATTERY
To ensure long life to the battery it is
essential to keep it carefully maintained.
The machine battery must always be charged:
• before using the machine for the
first time after purchase;
• before leaving the machine disused for
a long period (over 30 days) (par. 9);
• before starting up the machine after
a prolonged period of inactivity.
Carefully read and observe the battery
recharging instructions in the booklet provided
with the battery. Failure in following the procedure
or in charging the battery could permanently
damage the battery elements. A flat battery
must be recharged as soon as possible.
IMPORTANT Recharging must be
done using a battery charger at constant
voltage. Other recharging systems can
irreversibly damage the battery.
• The machine comes with a connector (fig.
31.A) for recharging; this is connected to
the corresponding connector for the special
maintenance battery-charger supplied (if
included) or available on request (par. 15.2).
IMPORTANT This connector must
only be used for connection to the
maintenance battery-charger indicated
by the Manufacturer. For its use:
– follow the instructions given in the
relative instructions manual;
– follow the instructions in the battery manual;
7.7 NUTS AND BOLTS
• Keep all nuts, bolts and screws tight to be sure
the equipment is in safe working condition.
8. EXTRAORDINARY MAINTENANCE
8.1 SAFETY RECOMMENDATIONS
You must go to a specialized
Service Centre or contact your Dealer
if the following are malfunctioning:
- the brake
- the cutting means engage
and disengage functions
- switching the drive to forward
or reverse gears.
8.2 CUTTING-MEANS ASSEMBLY
/ CUTTING MEANS
8.2.1 Aligning the cutting-means assembly
The cutting-means assembly should be properly
adjusted to obtain an evenly mown lawn (fig. 32).
If mowing is uneven, check the
tyre pressure (par. 6.1.3).
If this is not sufficient to achieve an even
cut, please contact your Dealer to adjust the
alignment of the cutting-means assembly.
8.2.2 Cutting means
A badly sharpened cutting means pulls at the
grass and causes the lawn to turn yellow.
All work on the cutting means
(disassembly, sharpening, balancing,
repairing, reassembly and/or replacing)
are demanding jobs that require special
skills as well as special tools. For
safety reasons, these jobs are best
carried out at a Specialised Centre.
Make sure damaged, misshapen
or worn cutting means are replaced
as a whole unit, together with its own
screws in place to preserve balance.
IMPORTANT Cutting means should
be replaced in pairs, especially when
there are marked differences in wear.
