ONLY USE THE PLATFORM LEVELING OVERRIDE FUNCTION FOR SLIGHT LEVELING OF
THE PLATFORM. INCORRECT USE COULD CAUSE THE LOAD/OCCUPANTS TO SHIFT OR
FALL. FAILURE TO DO SO COULD RESULT IN DEATH OR SERIOUS INJURY.
3. Platform Leveling Override
A three position switch allows the operator to
adjust the automatic self leveling system. This
switch is used to adjust platform level in situa-
tions such as ascending/descending a grade.
4. Axle Extend/Retract
Allows the operator to extend or retract
the axles. The axles can only be extended
or retracted while the machine is being
driven forward or reverse.
5. Horn
A push-type HORN switch supplies electrical
power to an audible warning device when pressed.
6. Indicator Panel
The LED Indicator Panel contains indicator lights that signal
problem conditions or functions operating during machine
operation.
Within about 2 seconds of pulling the Power/Emergency
Stop switch out, the machine will perform a diagnostic
check of the various electrical circuits, and if everything is
OK, the platform alarm will beep once. During this time the
lights on the indicator panel will also blink once as a bulb
check.
