: When the platform is raised 5 ft (1,5 m) from its stowed position, an alarm should sound
and platform raise is stopped. Drive function should not operate. Overload indicator light on the
platform controller should flash.
65. Completely lower the platform.
66. Remove the load from the platform.

platform should not operate and the overload indicator light should light continuously. First
remove the weight from the platform and then lower the platform.
Test the Pothole Guards

guards activate another limit switch which allows the machine to continue to function. If the
pothole guards do not deploy, the machine will not drive.
67. Place a piece of wood between the wheels on one side of the machine (under the pothole
guard).

from its stowed position, the drive function should become inactive.
If the drive function operates, immediately tag and remove the machine from service.
