Control StationControl Station
Only one operator control station can be activated at a
time for the paver to function. While the paver is typically
operated from the left side, the operator can change the
active station at any time using the following procedure:
1. Place both joysticks in the NEUTRAL (center)
position. (Figure 4-52 on the following page.)
2. Move the RUN/STOP switch to the STOP position
on the control box not being used to deactivate:
• The Run/Stop switch controls stopping the
machine and also activating/deactivating the
operator control station. When the switch is
set to the STOP position, that operator control
station is deactivated. When switch is set to
RUN, that operator control station is activated.
• BOTH joysticks must be in the NEUTRAL
position and BOTH Run/Stop switches in the
STOP position to change from one steering
control box to the other.
3. Activate the control box being used by setting the
Run/Stop switch to the RUN position.
4. Start the engine and allow the engine to warm a few
minutes.

Steering and Speed ControlSteering and Speed Control
Use the dual joysticks for steering and speed control. It
is important to move the joysticks SLOWLY. Lift up on
the joystick collar and move joystick either FORWARD
or REVERSE. The joystick collar will lock back into
place in the NEUTRAL position. The RUN/STOP switch
applies parking brake when set to the STOP position.
(Figure 4-52)
Be aware of the terrain and driving
conditions. Adjust speed accordingly.
NOTE: To slow the paver, move joysticks closer to
the neutral position.
NOTE: To stop the paver, pull joysticks back to the
neutral position.
• To drive the paver forward, lift up on the joystick collar
and push joystick forward to reach the desired speed.
• To move in reverse, lift up on the joystick collar and
move joystick backwards to reach desired speed.
• Return joysticks to the neutral position to stop paver.
• To steer the unit to the left, SLOWLY push the right
joystick farther forward than the left joystick. The
farther the joystick is pushed, the more the paver
turns. Slow and easy adjustments are required for
safe operation.
• To steer the unit to the right, SLOWLY push the left
joystick farther forward than the right joystick. The
farther the joystick is pushed, the more the paver
turns. Slow and easy adjustments are required for
safe operation.
NOTE: If the joysticks are in the forward position and
the Run/Stop switch is set to the STOP posi-
tion, the system will time-out after 30 minutes.
You must put joysticks back into neutral and
toggle the Run/Stop switch from RUN to STOP
and back to RUN again to regain control.
NOTE: If equipped with the optional steering wheel
control box: If the joystick steering function is
not being used, the Run/Stop switch must be
in the OFF position.
Before leaving the operator platform,
the operator must return joysticks to the neutral
position and switch the Run/Stop (on the Steering
and Speed Control Box) to the STOP position.
