Platform Station

(See Figure 3-3.)
1. Posi-Track Control
Activating the Posi-Track switch allows
the operator to engage positive trac-
tion for the time period pre-set in the
controller. Posi-traction occurs by changing the drive motors
from a series to parallel arrangement, causing available
power to be distributed evenly between the two drive
wheels. The control system may also engage the posi-track
function automatically.
ONLY USE THE PLATFORM LEVELING OVERRIDE FUNCTION FOR SLIGHT LEVELING OF
THE PLATFORM. INCORRECT USE COULD CAUSE THE LOAD/OCCUPANT TO SHIFT OR
FALL. FAILURE TO DO SO COULD RESULT IN DEATH OR SERIOUS INJURY.
2. 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.
