Test The Oscillate Axle - Gs-90 - Terex Genie GS-1330m Maintenance Manual

Test the Oscillate Axle - GS-90

Genie specifications require that this procedure be
performed annually.
The oscillate system is designed so that all four
tires maintain firm contact to the ground on unlevel
terrain improving traction and machine stability.
Proper axle oscillation is essential to safe machine
operation. If the axle oscillation system is not
operating correctly, the stability of the machine is
compromised and it may tip over.
Note: Perform this procedure on a firm, level
surface with the platform in the stowed position in
a safe, secure location away from obstacles and
with an area working height of 20 ft / 6 m.
Note: The outrigger, if equipped, must be fully
retracted.
1 Disconnect and remove the platform controller
from the platform.
2 Open the ground control panel door and
locate the cable connector below the ground
controls. Unplug the control cable from the
ground control plug and connect the platform
controller to the cable.
3 Remove the two retaining fasteners from the
ground control panel and set aside. Tilt the
control panel out towards you exposing the
wiring and relays.
