NOTE The battery is equipped with a guard
that inhibits recharging if the environmental
temperature is not between 0 and +45 °C.
IMPORTANT The battery can be
charged at any time, even partially,
with no risk of damaging it.
5.3.2 Check the battery charge status

the battery's residual charge will light up:
• three green lights and one red mean that
the charge ranges from 100% to 78%
• two green lights and one red mean that
the charge ranges from 77% to 55%
• one green light and one red mean that
the charge ranges from 54% to 33%
• a red light means that the residual
charge ranges from 32% to 10%.
• a blinking red light means that the charge
is lower than 10% and that the battery
should be recharged as soon as possible.
5.3.3 Refitting the battery on the machine
When recharging is completed:
1. disconnect the battery from
the battery charger
2. Disconnect the battery charger (fig.
