How to Adjust the Platform
Rotator
The platform rotator is designed to allow the
platform to slip in the event of striking an object to
help prevent damage to the platform. If the
platform rotator is too tight, or is seized, damage
to the platform may occur. If the platform rotator is
too loose, the platform may rotate side to side
unexpectedly, resulting in a unsafe operating
condition.

(0.9 m).
2 Activate the function enable switch and the
platform level toggle switch in the down
direction until the platform is horizontal. Do not
allow the platform to contact the ground.

the platform control box mounting fasteners.
Lay the platform controls off to the side.
Component damage hazard.
Cables can be damaged if they
are kinked or pinched.
4 Remove the fasteners from the platform rotator
cover then remove the cover.
5 Locate the locknut on the end of the platform
pivot shaft.
6 Tighten the locknut in the clockwise direction
on the platform pivot weldment shaft to make
the platform rotator tighter or loosen the
locknut in the counterclockwise direction to
make the platform rotator looser.

platform rotator assembly.
