4-30 LeeBoy 8515D Conveyor Paver
Operation
Unloading and Loading
Ensure the transport trailer has the capacity to carry
the paver’s weight. Park the trailer in a clear, level area
when loading or unloading the machine.
ALWAYS position an assistant to be a
ground guide when loading and unloading the paver.
Work slowly and carefully to avoid
accidents. Keep the loading area clear.
Unloading
1. Remove tie-down equipment.
2. Start and warm up engine.
3. Set throttle at half the operating RPMs, but enough
to ensure the hydraulic pump is providing sufficient
flow to operate all functions properly.
4. Set steering control lever so paver moves very
slowly.
5. BEFORE moving the machine, ensure:
• The screed position is UP.
• Auger extensions are removed.
• The extendible screed is IN.
• The cut-off gates below the augers are
CLOSED.
6. Move paver forward down the ramp as shown on
Figure 4-56 .
Never move the paver in reverse while
the cut-off gates are open.
DO NOT allow the screed to strike the
ramp as this can damage bearings on the thickness
control screws or welds on the leveling arms. A
longer ramp to reduce the loading angle may be
needed.

To make the AOA adjustment:
1. Spray down the screed.
2. Turn on the screed heat.
3. Turn the AOA adjuster in the direction for desired
result:
• Turning the AOA adjuster counterclockwise
will increase the pressure on the back of the
extension, which gives a smoother, slicker
finish.
• Turning the adjusters clockwise will decrease
the pressure on the back of the extension,
resulting in a coarser finish.
NOTE: Too much pressure on the back of the
screed extension will take the weight off the
screed wearplate and cause poor material
compacting, resulting in a poor finish.
815HD Screed Extension Double
Adjustment (Option)
There are also three adjusters on the optional 815HD
screed extensions.
(Page 4-35) If equipped with this
option, the two covered adjusters on each extension
(one on each side of the AOA adjuster) are for vertical
adjustment.
(Figure 4-55) The vertical adjusters
are preset by the manufacturer and should not need
adjustment.
Follow the same procedures for the AOA adjustment if
equipped with the 815D screed extension option.
