LeeBoy 8616 - Hydraulic Cutoff Gates Operation

6-12 LeeBoy Model 8616 Conveyor Paver
Operation
Manual Mode
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 manual mode.
Never work on paver with engine
running.
1. Spray the conveyor drive chains periodically. Spray
several times a day with cleaning solvent or release
agent.
2. When conveyors are running and cutoff gates
are shut, there will be spillage the full width of
conveyors. This is normal. To help prevent this
spillage, work conveyors manually when loading
hopper and not paving.
3. Irregular movement of the conveyor indicates that
a problem may exist with the conveyor chains.
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 let paver sit while conveyors
are turning.
To prevent ight chains from sticking,
lubricate them sufciently at the end of the day.

augers.
NOTE: Once desired speed is reached, the material will
come back and hit the manual paddles (Figure
6-9,1) on each side of the conveyor assembly.
This will raise the paddles and trigger the
paddles to turn off. When material is needed, the
paddles will drop down, triggering the conveyors
to turn back on.

NOTE: Conveyors can be run in manual mode and
augers in automatic mode. This is the preferred
way for running the LeeBoy Model 8616
Conveyor Paver.
Hydraulic Cutoff Gates
Operation
The cutoff gates are one of the most important functions
of the paver, when used properly. Cutoffs are used
primarilytocontroltheowofasphalttothescreed.
Cutoffs can be used when making narrow passes, at the
beginning and ending of each pass or pull.
Never backup with cutoff gates open.
Cutoff gates are designed to break away from
cylinders when hitting a manhole or other hard
object. This only occurs going forward not in reverse.
NOTE:TheRIGHTCUTOFFOPEN/CLOSEswitchand

the right and left cutoffs.

switches to the CLOSE positions decreases asphalt
owtothescreed.CUTOFFswitchesarespring-
loaded, to return to the “neutral” center position.
