7. ROUTINE MAINTENANCE
7.1 GENERAL INFORMATION
IMPORTANT The safety regulations to
be followed are described in chap. 2. Strictly
comply with these instructions to avoid
serious risks or hazards.
Prior to carrying out any
maintenance operation, you need to:
• stop the machine;
• Remove the battery from its housing
and recharge it (para. 7.2.2);
• allow the engine to cool before
storing in an enclosed space;
• use suitable clothing, protective
gloves and goggles;
• read the relevant instructions.
Warning! Risk of injuries due
to dangerous moving parts!
– The frequency and types of maintenance
are summarised in the "Maintenance
Table" (see chapter 12). The table will
help you maintain your machine's safety
and performance. It summarises the
main interventions to be made and the
frequency applicable to each of them.
Carry out the relevant task as soon
as it is scheduled to be performed.
– The use of non-original parts and
accessories could have negative effects
on machine operation and safety. The
manufacturer declines any responsibility for
damage or injury caused by said products.
– Genuine spare parts are supplied
by Authorised Assistance
Centres and Dealers.
IMPORTANT Any maintenance and
adjustment operations not described in this
manual must be carried out by the local
dealer or by an Authorised Service Centre.
7.2 BATTERY
7.2.1 Battery power reserve
Battery power reserve (and therefore
the cuttable area before recharging
is required) mainly depends on:
• operator behaviour that should be avoided:
– switching the machine on and off
frequently whilst working;
– a rotor speed not suited to the type of
material to be removed (paragraph 6.4.1).
To optimise battery power reserve
it is always recommended to:
• set a rotor speed suited to the type
of material to be removed.
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 (para. 14.1).
7.2.2 Battery removal and recharging
1. Press the locking button located in the
battery on the machine (Fig. 13.A) or on
the backpack (Fig. 14. A) (if available);
2. remove the battery from the machine
(Fig. 13.B) or from the battery
backpack (Fig. 14.B) (if available);
3. fit the battery (Fig. 15.A) in the battery
charger housing (Fig. 15.B);
4. Connect the battery charger (Fig. 15.B)
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
protective device 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
When recharging is completed:
1. Remove the battery from its housing in the
battery charger (Fig. 16.A) (do not continue
recharging once recharging is completed);
2. Disconnect the battery charger (Fig.
16.B) from the electrical mains;
3. insert the battery in its housing on the
machine (Fig. 11.A) or in one of the housing
of the battery backpack (Fig. 6) (if available)
4. push it completely, until hearing the
click that signals its locking in position,
ensuring thus the electrical contact.
