Platform Controls - Genie GS-3390 Service Manual

Section 4 • Repair Procedures

Platform Controls

The platform controls, used to activate machine
functions from the platform or while standing on the
ground, contain a printed circuit board, joystick,
decal membrane pad, buttons and/or toggle
switches, and LEDs. All of these components are
replaceable though only the potentiometer-
equipped joystick, used before serial number
GS9003-41523, is serviceable.
On models before serial number GS9003-41523,
the platform controls are also used to tune the
performance of the machine.
The function speed parameters in the Electronic
Control Module are easily adjusted by moving the
joystick, pressing a button or activating a toggle
switch in a specific order when the ECM is in the
programming mode (PS showing in the diagnostic
display window).
For further information or assistance, consult the
Genie Industries Service Department.
