LeeBoy 8608 - Sonic Auger Sensor; Set the Screed Extension, Flight Screw, and End Gate

Sonic Auger Sonic Auger
SensorSensor
The augers can be controlled
automatically when the sonic
sensor system is connected
to either side of the paver. The
sonic auger sensor detects the
amount of material present and
controls its ow to the end gates,
gauging the amount of paving
material in the extensions. The
sonic auger sensor sits in the
screed mount and connects to
the screed harness. (Figure
4-64)
Figure 4-64. Sonic Auger Sensor
NOTE: The augers are not needed when paving under
eight-feet wide.
To operate the sonic auger sensor:
1. Plug the sonic auger sensor unit into the connector
on the end gate.
2. On the main control panel, turn the left or right auger
switches ON. (Figure 4-65)

3. Set the left and right auger Auto/Off/Manual
switches on the screed control box to AUTO.
(Figure 4-70)
4. Adjust material height at the end gate using the
auger dial on the screed control box.
• Turning the dial clockwise increases material
height.
• Turning counterclockwise decreases material
height.
• When the material height moves into the
sonic range, the auger speed will slow down
proportionately and turn off. It will turn back on
when the material level drops.

The main screed is heated by S-curve heating elements
and equipped with replaceable, heavy-duty wear plates.
The screed extensions are heated by a blade element.
Dual vibrators, heavy-duty tow points, heavy-duty crown
and valley mechanism and a 3-Adjuster screed system
featuring AOA (angle-of-attack) and vertical height
adjustment add even more screed control.
Set the screed extension and its components when
paving widths exceeding eight (8) feet. (Figure 4-66)
You can extend or retract the screed extension using
the extension switches on the main control panel or
remote screed control box described on the following
page.
Heat screed extensions before making any adjustments.
(Use the wrench provided.) When adjusted correctly,
pressure on the rear edge of the extended screed is the
same as the rear edge of the main screed, resulting in a
smooth mat the length of the screed.
