7. MAINTENANCE
The safety regulations to follow are described in
chap. 2. Strictly comply with these instructions to avoid
serious risks or dangers.
Before conducting any inspections, cleaning or
maintenance/adjustment interventions on the machine:
• Stop the machine.
• Remove the safety key, (never leave the
key in the ignition or within reach of
children or unauthorised persons).
• Remove the battery.
• Make sure that all moving parts have
come to a complete stop.
• Allow the motor to cool before
storing in an enclosed space.
• Use suitable clothing, protective
gloves and goggles.
• Read the relevant instructions.
7.1 BATTERY
7.1.1 Battery power reserve
Battery power reserve (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 the energy needed.
c. Operator behaviour that should be avoided:
– 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 discharged battery, without
compromising the continuity of operations.
Purchase a battery with an extended power reserve
compared to the standard version (par. 13.2)..
7.1.2 Battery removal and recharging (Fig.30
-33
)
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 CLEANING
Clean thoroughly following the instructions
below every time it is used.
7.2.1 Cleaning the machine
• Do not spray water onto the motor and electrical
components and prevent them from getting wet.
• 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.
7.2.2 Cleaning the cutting blade assembly
IMPORTANT Tilt the machine laterally and make
sure that it is stable before starting any work.
Remove grass debris and mud accumulated in
the chassis to prevent it from drying and causing
problems the next time the lawnmower is used.
7.2.3 Cleaning the cooling air vents
To avoid overheating and damage to the
motor or the battery, always keep the cooling
air vents clean and free of debris.
Proced as follows:
1. Tilt the machine laterally and
make sure that it is stable.
2. Blow a jet of compressed air through
the cooling air vents (fig 34).
7.2.4 Cleaning the grass catcher
1. Empty the grass catcher
2. Shake it to remove grass cuttings and soil residue
3. Wash it, rinse it and fit it back so as
to facilitate quick drying.
7.3 BLADE
Badly sharpened blades pull at the grass
and cause the lawn to turn yellow.
Do not touch the blade until the key has been
removed and the blade is completely stationary. Bear in
mind that, even though the key has been removed, the
blade can still move.
All work on the blade (disassembly, sharpening,
balancing, repairing, reassembly and/or replacing) are
demanding jobs that require special skills as well as
