LeeBoy 8616 - Sonic Auger Sensor Adjustment; Auger Extensions

6-14 LeeBoy Model 8616 Conveyor Paver
Operation
Sonic Auger Sensor Adjustment
The sonic augers can be positioned accordingly to
control the pile height.
The end of the sensor must be kept
clean.
Automatic Mode
1. TurntheLEFTAUGERAUTO/OFF/MANUALswitch
and RIGHT AUGER AUTO/OFF/MANUALswitch to
the AUTO position. This will turn on the augers at
fullspeed.Atthispoint,theLEFTAUGERdialand
RIGHT AUGER dial control the pile height at the
endgate. When the material starts getting into the
sonic range, then the auger speed will slow down
proportionately until they turn off. They will turn back
on when material level drops proportionately.
NOTE: Speed is only adjusted on augers in manual
mode. Conveyors can be adjusted separately in
manual or auto modes.
Manual Mode
To operate the LeeBoy Model 8616 Conveyor Paver
inMANUALmode,turntheLEFTAUGERAUTO/OFF/
MANUAL switch and RIGHT AUGER AUTO/OFF/
MANUAL switch to the MANUAL position and slowly turn
LEFTAUGERdialandRIGHTAUGERdialclockwise
(CW) to reach desired speed for paving width and depth.
NOTE: When in MANUAL mode, the sonic auger
sensors are not used. The pile height is still
controlled by the conveyor speed and auger
speedbutyoumustusetheLEFTAUGER
AUTO/OFF/MANUAL switch and RIGHT AUGER
AUTO/OFF/MANUAL switch (Figure 5-6,3,11)
located on the screed operator control boxes
to manually control the conveyor and auger
speeds.
NOTE: When running material through the augers
manually,trytopavesomaterialowtothe
endgates is adequate and constant. Be careful
not to over-run the extension with material or
material will spill out around front of the endgate
and require more hand work.
Auger Extensions
The auger extensions should be attached to the main
augertoincreasetheowofasphalttotheendgates
and screed extensions when paving at widths wider than
15 ft (4.6 m). This makes it possible to lay asphalt at a
higher rate. To attach the auger extensions proceed as
follows:
Left and right auger extension covers
or shields must be installed on the correct side of the
machine.
1. Identify the right and left auger extensions by
observing the L (left) or R (right) on the end of the
auger extension shaft.
2. After identifying the right and left auger extensions,
extend the screed extension fully as follows:
 a.Onscreedoperatorcontrolboxes,setLEFT
AUGERAUTO/OFF/MANUALandtheRIGHT
AUGERAUTO/OFF/MANUALswitchestothe
OFFposition(Figure 5-6,3,11).
 b.Onscreedoperatorcontrolboxes,setLEFT
EXTENSION IN/OUT switch and the RIGHT
EXTENSION IN/OUT switch to the OUT position
and extend fully (Figure 5-6,4,10).
Engine must be shut off to prevent
possible injury when attaching extensions.
3. Shut off engine.
4. Remove bolt, nut cap on end of main auger.
5. Attach the correct side auger extension to the main
auger with hardware just removed.
6. Secure end of extension auger to main auger.
7. Install guard. Make sure extension auger is running
at.
8. Repeat this procedure for opposite side.
