6CHARGING OF BATTERIES
The engine of the drive is powered by batteries. Type: maintenance-free lead gel batteries 12 V/ 9
Ah-2 pc, which are charged using the battery charger.
If the platform is not operating for a longer period of time, it is necessary to control them regularly
and also charge them from time to time.
Also, it is appropriate to charge batteries before and after winter.
Batteries are to be charged always to full charge. A fully discharged battery must be charged as
soon as possible again. The battery that is kept in insufficiently charged state will be damaged and
it is not possible to renew its full capacity again. If the battery is fully charged it shows on the charger.
6.1 Light signals for charging, state of batteries and overload
In case the yellow signal LED lights up on the control panel the capacity of the battery is lowered.
Then move the platform into the lower stop (where it stops automatically) and connect the charger.
In case the capacity of the battery is insufficient, the red signal LED on the control panel lights up.
The control circuit ensures that the platform moves down to the lower end stop even with
insufficiently charged batteries. Then it is necessary to recharge the batteries or to change them.
In case the yellow signal LED is blinking while the platform is in the stop or during moving, the
platform is overloaded, and it is not possible to leave the stop safely. If this situation appears during
the operation, it is still possible to drive into the nearest stop.
6.2 Process of connecting the charger
Charging the batteries is possible in two ways:
1Connecting the charger with the external port. The battery does not need to be removed
from the platform.

Liftboy 4 | User handbook page 5
2Connecting the charger to the battery pack with the auxiliary port. The battery needs to be
removed from the platform and the charging is possible separately from the platform.
When connecting the charger, always connect the charging connector to the battery pack
or to the external charging connector first.
Then connect the charger to the socket 1 x 230 V 50/60 Hz
After removing the
battery pack, it is
necessary to disconnect
charging connector.
