LeeBoy 8515E Conveyor Paver 4-25
Operation
Gauge
Figure 4-49. Gauge and Cable Rod End
1. Before paving, refer to the screed elevation gauge
(located on both sides of the operator platform, left
side shown). (Figure 4-49)
2. Raise or lower the screed until the cable rod end is
ush with “0”on the decal.
3. Set the Tow switch on both sides to thicker or
thinner for desired asphalt thickness. (Figure 4-50)
4. Slowly move joysticks forward.
5. Use the Tow switch on both sides of the control
panel to adjust mat thickness as you pave. (Figure
4-50)

6. While paving, refer to both screed elevation gauges
to make minor screed adjustments using the elec-
tric ight screw.
Operating in AUTO mode:
You will need the TopCon sonic grade/slope system to
operate in AUTO mode. (See Page 4-35) The TopCon
control system must be connected to operate in AUTO
mode.
• The Tow Up and Down switches will not function in
AUTO mode unless joysticks are in neutral.
Under Auger Material Cut-Offs Under Auger Material Cut-Offs
The Under Auger Material Cut-Offs are another impor-
tant function of the paver, used primarily to control
the ow of asphalt to the screed and hydraulic screed
extensions. (Figure 4-48) Cut-offs can be used to limit
material ow when making narrow passes at the begin-
ning and ending of each pass or pull. Proper use of the
cut-offs minimizes clean-up at the end of pulls.
Cut-O Switches
Figure 4-48. Under Auger Material Cut-Off Switches
• The right and left cut-off switches are used to open
and close the cut-off gates and are located on both
the main control panel and the screed controls.
• Pushing the switch to the OPEN positions increases
asphalt ow to the screed. Pushing the switch to
the CLOSED position decreases asphalt ow to the
screed.
NEVER back up with the cut-offs
open. The cut-offs are designed to break away from
cylinders when hitting a manhole or other object
when moving forward, but not in reverse.
Electric Flight Screw Electric Flight Screw
The electric ight screw is an added convenience to the
operator for making automatic, minor adjustments to
mat thickness while paving.
A screed height gauge is located on both sides of the
paver to provide the operator with a quick reference to
the location of the electric screw. (Figure 4-49)
NOTE: The Grade Control switch on the main control
panel must be set to GRADE for this feature to
operate.
