LEKTRO 88/89 SERIES - OPERATION MANUAL

CHARGING THE GPU BATTERIES
To charge the GPU Batteries:
1. Position the tractor and charger in a well-ventilated area on a stable surface, away from
precipitation, standing water, and condensation.
2. Open the GPU Deck Cover to allow the explosive gases generated by the charging process
to ventilate. See
"OPENING A COMPARTMENT” on page
.
3. Check the electrolyte level in the GPU Batteries to verify that the plates in the battery cells
are covered with electrolyte and that the cells are below the maximum fill level.
4. Connect the tractor Charger Output Cable from the GPU Battery Charger to the tractor GPU
Power Connector on the GPU Batteries.
5. Connect the AC Power Cable from the GPU Battery Charger to the incoming AC power
supply.
6. Check the Volt/Ampere Display to verify that the charger is supplying power to the tractor.
> A battery discharged to 20% remaining power should show a maximum ampere draw.
> A battery nearly fully charged should show a draw of approximately 10 amperes.
> The Volt/Ampere Display reading should gradually taper off until the finished rate of
approximately 5 to 10 amps is reached.
7. When the batteries are fully charged, disconnect the GPU Battery Charger from the
incoming AC power supply first.
8. Disconnect the GPU Battery Charger from the tractor GPU Power Connector.
9. Close the GPU Deck Cover. See
"CLOSING A COMPARTMENT” on page
.
Charging the GPU Batteries will take approximately eight to ten hours when the batteries have
been discharged to the 20% level.
Note
The fully automatic GPU Battery Charger supplied with this tractor will automatically
shut off when a full charge is reached. You may leave this charger unattended
overnight, because overcharging is not normally a concern.
