Ground Controls

The ground controls, used to operate the machine
from the ground, can also be used to tune the
performance of the machine.
The ground controls consist of an Electronic
Control Module (ECM), emergency stop button,
key switch and circuit breaker.
Activating the function enable button and the up
or down at the same time, sends a signal to the
(ECM). This allows the platform to be raised or
lowered at the ground controls.
Note: Steer and drive functions are not available at
the ground controls.
When the ECM is in the set up mode, the ground
controls are used to adjust the function speed
parameters, machine models, or machine options.
For further information or assistance, consult the
Genie Industries Service Department.
