Platform Control Station
See Figure 3-4.
1. Posi-Track
When one wheel is slipping and the machine is not
descending a grade, automatic traction control will pro-
vide added torque to both wheels. While this function is
automatic, it may also be manually engaged by moving
the toggle switch to the forward position. Positrac will be
engaged for approximately 20 seconds.
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.
2. Platform Leveling Override
The PLATFORM LEVEL control switch allows the opera-
tor to adjust the level or the platform by positioning the
switch to UP or DOWN. The switch is used to adjust the
platform level in situations such as ascending/descend-
ing a grade.
3. Horn
A push-type HORN switch supplies electrical power to
an audible warning device when pressed.
4. Power/Emergency Stop
A two-position red mushroom shaped switch furnishes
power to PLATFORM Controls when pulled out (on).
When pushed in (off), power is shut off to the platform
functions.
5. Lights (If Equipped)
This switch operates control console panel lights and
head lights if the machine is so equipped.
