STEERING WHEEL AND CONTROLS

The steering wheel (1, Figure 3-2) will telescope ''in''
and ''out'' and adjust through a tilt angle to provide a
comfortable wheel position for most operators.
HORN BUTTON
The horn (2, Figure 3-2) is actuated by pushing the
button in the center of the steering wheel. Operation of
the horn should be verified before moving the truck.
Observe all local safety rules regarding the use of the
horn as a warning signal device before starting engine
and moving the vehicle.
TELESCOPE LOCK RING
The Telescope Lock Ring (3, Figure 3-2) around the
horn button locks/unlocks the telescoping function of
the steering column. Rotating the ring (* ) counter-
clockwise (L.H. rotation), releases the column to move
"in" or "out". Rotating the ring clockwise (R.H. rotation),
locks the column in the adjusted position.

adjustment lever (4, Figure 3-2) toward the steering
wheel and moving the wheel to the desired angle.
Releasing the lever will lock the wheel in the desired

display panel will illuminate to indicate turn direc-
tion selected.
