LeeBoy Model 8510B Conveyor Paver 6-17
Operation
Screed extension double adjustment:
NOTE: Double Adjuster extensions are optional.
1. There are two adjusters at each end of the
extension (Figure 6-16,1,2) . The adjuster farthest
from the extension center is the vertical adjustment.
NOTE: Vertical Adjuster is preset by dealer and should
not need adjustment.
Mat Texture Double Adjusters
Figure 6-16
1 – Vertical Adjuster
2 – Extension Angle of Attack (AOA) Adjuster
2. Turning the AOA adjusters (Figure 6-16,2)
clockwise will increase the pressure on the back
of the extension. Turning the AOA adjusters
counterclockwise will decrease the pressure on the
back of the extension.
NOTE: Increasing the pressure on the back of the
extension will give you a smoother, slicker finish.
Decreasing the pressure will give you a coarser
finish. Putting too much pressure on the back
of the extension will take the weight off of the
screed wearplate and will cause poor material
compaction, resulting in a poor finish in the
middle of the main screed.
Unloading And Loading
The following procedure applies to loading and
unloading the machine when there is a large height
difference between the loading and unloading surfaces
and is intended to avoid damage to the screed. In
locations where there is no height difference and there
is no risk of screed damage from striking the ramp, then
the machine may be loaded or unloaded facing either
direction.
Trailers used to haul the paver should have ample
capacity to carry the weight of the paver. Place the
trailer in a clear, level area for loading or unloading.
Work slowly and carefully to avoid
accidents. Keep the area clear.
Unloading
1. Remove tie down equipment.
2. Start and warm up engine.
3. Set throttle at 1/2 operating RPM. Set steering
control lever so paver moves very slowly.
4. Make sure:
a. Screed position - UP
b. Auger extensions removed
c. Extendible screed - IN
d. Gates below augers - CLOSED
Never back up with cutoff gates open.
Correct Unloading
Figure 6-17
NOTE: A man should always be on the ground to assist
the operator in the unloading procedure.
Make sure engine is operating at a high
enough RPM so that the hydraulic pump is providing
sufficient flow to operate all functions properly.
Do not let the screed strike the ramp
when moving off the ramp. This can break the
bearings on the thickness control screws or welds
on the leveling arms. A longer ramp or blocks may be
necessary to reduce the loading angle.
NOTE: If you have a problem unloading the paver -
STOP - LOOK - THINK.
5. Move paver forward down the ramp as shown
( Figure 6-17) .
