LeeBoy Model 8510B Conveyor Paver 6-7
Operation
Paver Operation
1. Follow start-up procedures (see Starting The
Engine in Section 6).
2. Position paver to start of mat.
3. Open cut-off gates under auger.
4. Adjust screed as needed (see Setting Screed To
Pave in Section 6).
5. When material starts to discharge from under
screed, the SCREED LIFT RAISE/FLOAT lever on
the dash should be set to the FLOAT position (One
side only).
6. Open hopper wings into working position. When rst
starting to pave allow only a partial load of asphalt to
enter the hopper.
Never fold hopper wings fully in when
hopper is full of asphalt.
7. Set the LEFT CONVEYOR and RIGHT CONVEYOR
AUTOMATIC/MANUAL switches to the AUTOMATIC
position and convey material back to screed. Run
from one side only. Either the left operator’s side or
the right.
NOTE: Augers are not needed when paving a basic 8
foot pull.
8. Start paving. Move slowly at rst so adjustments can
be made to screed.
Never backup with cut-off gates
open. Cut-off gates are designed to break away
from cylinders when hitting a manhole or other hard
object. This only occurs going forward not in reverse.
9. To prevent excessive handwork, about 2 to 3 ft. (0.6
to 0.9 m) from end of pull, Set the LEFT CONVEYOR
and RIGHT CONVEYOR AUTOMATIC/MANUAL
switches to the OFF position and set LEFT CUTOFF
and RIGHT CUTOFF switches to the CLOSE
position. Return paver back to starting position to
begin next pull. Position and set screed endgate on
joint side back to 0 ft. or ush with bottom of main
screed. Repeat process as done in rst pull.
10. The paver can operate using one side only.
However, material from opposite side cannot be
augered to the working side. The auger center
cover prevents this. It is possible to leave both
cutoffs shut and open the end gates on screed. This
method is generally used in doing potholes and
patching.
Conveyor Operation
The conveyor is a very important part of the paver
and for this reason close attention should be given on
integrating its operation into the total operation of the
paver. Use the following procedure for operating the
conveyor.
Never use cylinder pressure to lower
sides into place after lowering conveyor. This may
bend sides or break the chains on the sides.
Never work on paver with engine
running.
1. Before raising or lowering conveyor, remove bolts,
in hinges and fold side wings in and out by hand. The
side wings have a double action motion causing the
in and out movement.
NOTE: The engine must be shut off when lowering the
conveyor.
2. When lowering conveyor, do not lower under
pressure. Let the conveyor down with engine shut
off by placing the CONVEYOR RAISE/LOWER lever
in the LOWER (down) position.
Do not let the paver sit running with
conveyors in automatic for any length of time. This
may cause the hydraulic oil to over heat.
3. Spray the conveyor drive chains periodically. Spray
several times a day with cleaning solvent or release
agent (see Spray Down in Section 6).
4. When conveyors are running and cutoff gates are
shut, there will be spillage the full width of the paver.
This is normal. To help prevent this spillage, work
conveyors manually when loading hopper and not
paving.
5. Irregular movement of the conveyor indicates
that a problem may exist with the conveyor chain.
To eliminate this problem an adjustment to the
conveyor chain may be necessary (see Conveyor
Flight Chain Adjustment in Section 7).
NOTE: Check adjustments every 100 hours.
Never work on conveyors with engine
running.
Never raise conveyor with asphalt in
the hopper.
Crush Hazard! Never work under
conveyor without making sure that conveyor is being
supported by safety prop and that all unauthorized
personnel are clear of the area.
