If the lift truck has been operated with a low battery,
check the contactors for welded contacts before a
charged battery is connected. The circuit will not reset
and lift truck operation cannot be controlled if the con-
tacts are welded. To check the contacts, see the Con-
tactor Inspection procedure for your lift truck.
CAUTION
Use only battery chargers approved by the battery
manufacturer or dealer.
CAUTION
NEVER connect the battery charger plug to the plug of
the lift truck. You can damage the traction control cir-
cuit. Make sure the charger voltage is the correct volt-
age for the battery.
Troubleshooting Charger
Battery chargers normally operate automatically without
constant attention. It is necessary to make a periodic check
that the charger is operating correctly. Refer to Step 2.
Knowing When Battery Is Fully Charged
WARNING
Always connect the positive cable to the positive termi-
nal and connect the negative cable to the negative ter-
minal. Any other connection will cause injury and
damage.
NEVER connect the battery charger plug to the plug of
the lift truck. You can damage the traction control cir-
cuit. Make sure the charger voltage is the correct volt-
age for the battery.
1. The battery charger will indicate charge is complete by
illuminating the Green Charged LED.
2. If the battery charger is OFF, wake-up battery and meas-
ure the voltage across terminals. If voltage is above 28
Vdc, the battery is at or near full charge.
Where To Charge Batteries
As Lithium-Ion batteries are kept with the vehicle, unless
servicing, all charging is done using the on-board charger.
The vehicle should be stored in a location within charging
temperature 0 to 45° °C (32 to 113° °F). The AC Power
should be per code standards and properly fused.
