GRC

™

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, contact

Genie Product Support.
