The upper controls will not operate while the
control selector is in the lower position.
Turn the switch to the upper controls position to
operate the aerial platform functions from the upper
controls.
In the center position, aerial platform functions will
not operate from the lower or upper controls.

Platform Raise/Lower Switch

Pull up on the platform switch toward the white
arrow to raise the platform. Release the switch
when the desired height is reached.
