The following sequence of basic procedures must be fol-
lowed to safely operate the machine.
1. At the ground control station, set power PLAT/OFF/
GRND key switch to the PLAT position to operate

controller box at machine power-up, see Section-3,
“Troubleshooting” of the Service and Maintenance
Manual for information on reading fault codes.
2. Check LED strip on the platform controller for cur-
rent battery charge level before operating lift to be
