Motor Controller
The drive motor controller is located under the
non-steer end drive chassis cover. The drive motor
controller can recognize machine drive
malfunctions and display controller fault codes by
flashing a LED at the ground controls and on the
motor controller. See the Fault Code section of this
manual for a list of fault codes and additional
information. There are no adjustments needed on
the drive joystick controller. For further information
or assistance, consult the Genie Industries Service
Department.
