18. Steer Select
The action of the steering system is operator selectable.
The center switch position gives conventional front
wheel steering with the rear wheels unaffected. This is
for normal driving at maximum speeds. The forward
position is for “crab” steering. When in this mode both
front and rear axles steer in the same direction, which
allows the chassis to move sideways as it goes forward.
This can be used for positioning the machine in aisle
ways or against buildings. The back switch position is
for “coordinated” steering. In this mode the front and
rear axles steer in the opposite directions to produce the
tightest turning circle for maneuvering in confined areas.
To re-synchronize the front and rear axles, position the
rear drive wheels to the forward drive position by select-
ing either crab or compound steer, then select front
steer (center switch position) to operate the normal
steering function.
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.
19. 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 situations such as ascending/
descending a grade.
20. Horn
If pressed, this switch supplies power to the horn.
