LeeBoy 8510b - Hydraulic Cutoff Gates Operation; Sonic Augers Operation

6-8 LeeBoy Model 8510B Conveyor Paver
Operation
Never let paver sit while conveyors
are turning. If paver sits long enough, asphalt from
conveyors can ll tracks and cause failure to the
bearing or idler.
To prevent ight chains from sticking
inside of conveyor pans, lubricate them sufciently
at the end of the day.
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 passes, at the
beginning and ending of each pass or pull.
NOTE: The cutoffs have been designed to break away
if you accidentally hit a manhole or ridge. This
feature will prevent excessive damage to cutoff
(tack weld underneath will break).
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 lever and the
LEFT CUTOFF OPEN/CLOSE lever control the
right and left cutoffs.
NOTE: Moving the handles upward to the OPEN
positions increases asphalt ow to the screed.
Moving the handles downward to the CLOSE
positions decreases asphalt ow to the screed.
Sonic Augers Operation
The sonic augers are most often used when paving 9
or 10 ft. (2.7 or 3 meters) where augers are capable of
running material over top of endgates, causing extra
handwork. The sonic auger gauges the amount of
material that is in the extensions.
Never run augers when paving 8 ft.
(2.4 m) wide.
NOTE: An operator can operate the Auger from either
side standing on or sitting in the Low Deck
position.
1. Set the LEFT AUGER and RIGHT AUGER automatic
toggle switches on the main dash to the ON
position.
2. Pull the auger levers to ON to ll the end gates. The
sonic will turn the auger OFF and ON, automatically.
To override the automatics, the toggle switches
must be set to MANUAL.
NOTE: The sonic auger adjustment dial adjusts the
amount of material needed in AUTOMATIC
setting only.
NOTE: The + and - on the sensor have nothing to do with
the setting of the sensor. They are for factory
settings only.
3. Adjust height of material at endgate with the sonic
auger adjustment (Figure 6-3,1). Turn the dial to
keep the extension full. Be careful not to over run
the extension with the material.
NOTE: When running material through augers manually,
try to pave so material ow to extension is
adequate and maintained.
To prevent hydraulic oil from
overheating, turn conveyor and augers OFF while
waiting on material or hand work.
4. When paver stops, set the LEFT AUGER and RIGHT
AUGER switches on the dash to the OFF (center)
position and push auger levers to OFF.
