Platform Controls
The platform controls are used to operate the
machine from the platform.
Activating a function button sends a signal to the
Electronic Control Module (ECM). When the ECM
is in the function mode, the platform controls are
used to operate the various machine functions.
The platform controls consist of an Emergency
Stop button, electronic circuit board, proportional
control handle, drive/steer enable switch, alarm,
function buttons and LED display.
For further information or assistance, consult the
Genie Industries Service Department.

Operational Indicator Codes
These codes are generated by the electrical
system to indicate machine operating status.
During normal operation a code will appear in the

guards stuck occurs.
If the platform controls LED readout displays an
operational indicator code such as LL, the fault
condition must be repaired or removed before
resuming machine operation. Push in and pull out
