Test the Oscillate Axle -
GS-90 Models
Genie specifications require that this procedure be
performed daily or every 8 hours, whichever comes
first.
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 with the platform
extension(s) in the retracted position with no
additional weight in the platform.
1 Start the engine from the platform controls.
Select the high idle function.
Test the Oscillate System (stowed position):
2 Drive the left steer tire up onto a 4 in / 10 cm
high ramp.
Result: All four tires should maintain firm
contact with the ground.
3 Drive the right steer tire up onto a 4 in / 10 cm
high ramp.
Result: All four tires should maintain firm
contact with the ground.
3 - 10

5 Drive the left steer tire into a 4 in / 10 cm deep
hole.
Result: All four tires should maintain firm
contact with the ground.
6 Drive the right steer tire into a 4 in / 10 cm deep
hole.
Result: All four tires should maintain firm
contact with the ground.
Note: Verify there are no fault codes shown on the
