Onboard Battery Charger
To charge the batteries, first drive the machine to a flat, dry, well-ventilated area then turn the machine
off. If using lead acid batteries, check the water level in all the battery
cells. If the level is low,
add just enough distilled water to cover the plates. **DO NOT OVERFILL.**
Then plug the charger cord into a wall socket. The battery charger will initialize and then soft start the
charging cycle.
WARNING! Batteries emit hydrogen gas when charging. Explosion or fire can result. Keep sparks
and open flame away when charging.
CAUTION! When servicing machine, wear protective gloves and goggles when handling batteries
or battery cables. Avoid contact with battery acid.
Battery Charger Controls:
1. Three-digit d symbol (1), to view A=charging current, U=battery voltage, h=charging time,
C=charging ampere-hours (AH), E=energy used to charge (KWh)
2. Button for the Selection of the display mode (2): A, U,h, C, E. After 10 seconds the display returns to
the display of charging current.
3. Red control indicator (3): when it is on, the charging cycle has started.
4. Yellow control indicator (4): when it is on, the final phase of the charging cycle has started.
5. Green control indicator (5): when it is on, the charging cycle has finished.
Once the charge cycle is complete, the charger will remain active in a trickle charge mode to maintain the
charge on the batteries until the charger is unplugged from the wall socket.
