ConveyorsConveyors
The LeeBoy Model 8515E Conveyor Paver is equipped
with two automatic conveyors that deliver asphalt evenly
to produce a smooth asphalt mat. (Figure 4-45)
The conveyor is a very important part of the paver that
moves material from the hopper back to the auger
and through the Under Auger Material Cut-Offs to the
screed. Pay close attention to integrating its operation
into the total operation of the paver.
When operating the conveyor:
• Spray down the conveyor drive chains with cleaning
solvent or release agent several times during the work
day for optimum performance.
• Select AUTO or MANUAL mode for the left or right
(or both) conveyor switch(es) on the control panel.
(Figure 4-45)

• If the conveyors are running while the cut-off gates are
closed, there will be spillage, which is normal. To help
prevent this spillage, work conveyors manually when
loading hopper and not paving.
• Irregular movement of the conveyor indicates that the
conveyor chains need adjustment. (See Section 5)
NOTE: Check conveyor chain adjustment every 100
hours.
NEVER leave the paver unattended
while the conveyor is operating. DO NOT leave paver
running with conveyors set to AUTO for any length of
time to prevent hydraulic oil overheating.
Asphalt in the conveyors can ll tracks
and cause damage to the machine. To prevent
ight chains from sticking inside the conveyor
pans, lubricate them daily for maximum operational
efciency.
