7.2 BATTERY
7.2.1 Battery power reserve
Battery power reserve (and therefore the mowable lawn
surface before recharging is required) mainly depends on:
a. environmental factors, that cause higher energy
requirements:
– mowing dense, high and/or wet grass;
b. machine cutting width; the wider the width, the greater
is the energy need;
c. operator behaviour, who should avoid:
– switching the machine on and off frequently whilst
working;
– setting a cutting height that is too low for the lawn
conditions;
– working at a speed that is too high in relation to the
amount of grass to be removed.
NOTE
During use, the battery is protected against total
drainage with a protective device that switches off the
machine and stops it from working.
To optimise battery power reserve it is always recommended
to:
• cut the grass when the lawn is dry;
• cut the grass frequently so that it doesn't grow too tall;
• set a higher cutting height when the grass is very tall,
then set a lower height and cut the lawn again;
• do not use the machine in "mulching"
mode when the grass is very tall.
If the need arises to use the machine for sessions which
exceed the capability of a standard battery, it is possible to:
• purchase a second standard battery to immediately
replace the worn down battery, without
compromising the continuity of operations;
• – purchase a battery with an extended power reserve
compared to the standard version (par. 15.1).
7.2.2 Battery removal and recharging
1. Open the battery housing hatch and remove the safety
key.
2. press the botton on the battery (fig. 16.A) and remove
the battery (fig. 16.B) ;
3. insert the battery (fig. 17.A) into its housing in the
battery charger (fig. 17.B);.
4. connect the battery charger to a power socket with the
voltage indicated on the rating plate.
5. fully charge the battery according to the instructions in
the battery/battery charger booklet.
NOTE The battery is equipped with a guard that inhibits
recharging if the environmental temperature is not between
0 and +45 °C.
NOTE The battery can be recharged at any time, even
partially, with no risk of damaging it.
7.2.3 Refitting the battery on the machine
When recharging is completed:
1. Remove the battery from the housing in the battery
charger (do not keep recharging when recharging is
completed);
2. disconnect the battery charger from the mains;
3. open the battery housing hatch ( fi g. 18.A) , insert the
battery ( fi g. 18.B) into its housing pressing down until
you hear it click firmly into position and check the
electrical contact;
4. completely close the hatch again.
7.3 CLEANING
Clean thoroughly following the instructions below every
time it is used.
7.3.1 Cleaning the machine
• Always make sure the air intakes are free of debris.
• Do not spray water onto the motor and electrical
components and prevent them from getting wet (fig. 19).
• Do not use aggressive liquids to clean the chassis.
• To reduce fire hazards, keep the lawnmower and in
particular, the motor free of grass, leaves or excessive
grease.
7.3.2 Cleaning the cutting-means assembly
Remove grass debris and mud accumulated in the chassis
to prevent it from drying and causing problems the next time
the lawnmower is used.
Tilt the machine laterally and make sure that it is stable
before starting any work.
Paint on internal chassis parts may come off over time due
to the abrasive action of cut grass; if this happens, promptly
touch-up paint with rust-proof paint to prevent rusting that
could corrode the metal.
7.3.3 Cleaning the grass-catcher
1. Empty the grass catcher (Fig. 20.A);
2. shake it to remove grass cuttings and soil residue;
3. wash and rinse it (Fig. 20.B), then place it where it can
dry quickly.
7.4 NUTS AND BOLTS
Keep all nuts, bolts and screws tight to be sure the
equipment is in safe working condition. .
