Proper key switch action and response is essential to safe machine operation. The
machine can be operated from the ground or platform controls and the activation of one
or the other is accomplished with the key switch. Failure of the key switch to activate the
appropriate control panel could cause a hazardous operating situation.
Perform this procedure from the ground using the platform controls. Do not stand in the
platform.
1. Turn the red Emergency Stop button clockwise to the on position at both the ground
and platform controls.
2. Turn the key switch to platform control.
3. Check the platform up/down function from the ground controls.
• Result: The machine functions should not operate.
4. Turn the key switch to ground control.
5. Check the machine functions from the platform controls.
• Result: The machine functions should not operate.
6. Turn the key switch to the off position.
• Result: No function should operate.

wise to the on position at both the ground and platform controls.

Proper brake action is essential to safe machine operation. The drive brake function
should operate smoothly, free of hesitation, jerking and unusual noise. Hydraulically-
released individual wheel brakes can appear to operate normally when not fully
operational.
Perform this procedure with the machine on a firm level surface that is free of
obstructions, with the platform extension deck fully retracted and the platform in the
stowed position.
1. Mark a test line on the ground for reference.
2. Turn the key switch to platform control and turn the red Emergency Stop button clock-
wise to the on position at both the ground and platform controls.
3. Press the drive function select button.
4. Choose a point on the machine; i.e., contact patch of a tire, as a visual reference for
use when crossing the test line.
5. Bring the machine to top drive speed before reaching the test line. Release the func-
tion enable switch or the joystick when your reference point on the machine crosses
the test line.
