From the ground controls, raise and lower platform 2 ft to 3
ft (0.61 m to 0.92 m) several times. Check for smooth eleva -
tion and lowering of platform.
4.
Ensure the castor wheels lock when set and stop all machine
movement.

Operate the machine from the platform controls:
a.
Ensure all platform movement stops immediately when
the enable, up, or down buttons are released.
