7. ROUTINE MAINTENANCE
7.1 GENERAL INFORMATION
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;
• Wait until the cutting means stops;
• Remove the battery from its housing;
• Apply the blade protection cover, except
when working directly on the blade.
• Wait until the motor is sufficiently cold;
• Read the relevant instructions;
• Use suitable clothing, protective gloves and
goggles.
The frequency and types of maintenance are
summarised in the "Maintenance Table". This
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
intervention according to the first deadline.
• The use of non-genuine and/or incorrectly
assembled spare parts and attachments
could adversely affect machine operation
and safety. The manufacturer shall
decline all liability in the event of injuries
or damages caused by such parts.
• Genuine spare parts are supplied by
authorised assistance workshops and dealers.
IMPORTANT Any maintenance and
adjustment operations not described in
this manual must be carried out by your
dealer or Authorised Service Centre.
7.2 BATTERY
7.2.1 Battery power reserve
Battery autonomy is mainly influenced by:
a. environmental factors, that cause
higher energy requirements:
– cutting/trimming of very thick or wet hedges;
– cutting/trimming of bushes with
branches that are too thick.
b. operator behaviour that should be avoided:
– switching the machine on and off
frequently whilst working;
– adopting a cutting technique
that is unsuitable for the work to
be performed (par. 6.4.1).
To optimise battery power reserve
it is always recommended to:
• cut the hedge when dry;
• use the most appropriate technique
for the work to be performed
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. 15.1).
7.2.2 Battery removal and recharging
1. Press the lock push-button placed in the
battery on the machine (Fig. 15.A) or on
the backpack (Fig. 16. A) (if provided)
2. remove the battery from the machine
(Fig. 15.B) or from the battery
backpack (Fig. 16.B) (if provided).;
3. fit the battery (Fig. 17.A) in the battery
charger housing (Fig. 17.B);
4. connect the battery charger (Fig.17.C)
to an electrical outlet having a voltage
matching that indicated on the nameplate.
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 (Fig. 18.A) from its
housing in the battery charger (Fig. 18.B)
(avoiding to keep it too long under
charge after recharging is completed);
2. disconnect the battery charger
(Fig. 18.C) from the mains;
