with products containing solvents or ammonia.
Natural separation will occur in about 48 to 72 hours.
Get medical attention as soon as possible.
• DO NOT remove radiator cap, drain plugs, service
grease ttings, or pressure taps while engine is hot.
Add coolant to the radiator and perform other services
only when the engine is stopped and fully cooled.
Hydraulic Systems Precautions
• Ensure all components are in good working condition.
Replace any worn, cut, abraded, attened or crimped
hoses and metal lines.
• DO NOT attempt makeshift repairs using tape, clamps
or cements. The hydraulic system operates under
extremely high pressure and such repairs could
cause serious injury.
• Wear proper hand and eye protection when checking
for a high pressure leak. Use a piece of wood or
cardboard as a back stop to isolate and identify leaks.
Hydraulic oil under pressure can
cause serious personal injury. Check for oil leaks
with a piece of cardboard. DO NOT expose hands to
possible high-pressure oil. Turn off engine before
attempting to tighten oil lines and ttings.
• Escaping pressurized hydraulic uid has force
sufcient to penetrate the skin, which could cause
serious personal injury. Ensure all pressure is
relieved before disconnecting line, hoses or valves.
1
LeeBoy 8515D Conveyor Paver 1-7
• If injury from concentrated high pressure steam
or hydraulic uid occurs, seek medical attention
immediately. Injuries resulting from hydraulic uid
penetrating the skin’s surface can result in serious
infections or toxic reactions.
Safety
Refueling Precautions
• Do NOT overll the fuel tank as overow creates a re
hazard when spilled on hot components.
• DO NOT smoke when refueling and never refuel when
the engine is running. Fuel is highly ammable and
should be handled with care. Death or serious injury
can occur due to explosion and/or re.
• DO NOT ll tank to capacity. Allow room for expansion
to reduce the risk of fuel expanding and spilling from
the tank.
• Tighten fuel cap securely. Should fuel cap be lost,
replace it with an original manufacturer’s approved
cap. Pressurization of the tank may result from use of
non-approved cap.
• Prevent res by keeping the machine clean of
accumulated debris, grease, and spilled fuel.
• Use ultra-low sulfur diesel fuel (ULSD) only.
Battery Precautions
• Keep all sparks and ames away from batteries, as
gas given off by electrolytes is explosive.
• Acid propelled by an explosion can cause blindness
if it comes in contact with eyes. Always wear safety
glasses when working near batteries.
• If you come in contact with battery electrolyte solution,
wash off immediately. Chemicals can cause burns.
• Always disconnect the battery ground cable before
working on the electrical system to avoid injury from
spark or short circuit. Electrical shock and burns can
occur.
• To avoid electrolyte loss, DO NOT tip batteries more
than 45 degrees.
Starting and Stopping
Precautions
• Check all around the paver to make sure there are no
people working on the machine or in the path of the
machine before starting. DO NOT start until area is
clear. Death or serious injury can occur to bystanders
from being crushed under a moving machine.

Safety Decals Care
1. Keep safety decals and signs clean and legible at all
times.
2. Become familiar with the content and the position
of each safety decal. Decals include important
information.
3. Replace decals and signs that are missing or
become impossible to read.
4. When replacing parts that display a safety decal,
ensure that the new part is tted with a decal as well.
5. Obtain replacement safety decals or signs from
your authorized LeeBoy dealer.
Decal Installation (Sticker Type)
1. Be sure that the installation area is clean and dry.
Use hot, soapy water to clean the surface where the
decal will be applied.
2. Thoroughly dry the surface.
3. Measure and t decal before removing the paper
backing.
Decal Installation (Top
Protected)
1. If the decal has a protective top paper, use hot
soapy water on the surface where the decal will be
applied. Leave wet.
2. Determine the proper location, remove protective
back paper and soak decal in clean soapy water
before application. This will help to alleviate air
bubbles in the applied decal.
3. Smooth decal into place with a squeegee and check
for air bubbles.
4. Small air pockets can be pierced with a pin and
smoothed out using a piece of the decal backing.
5. When decal is completely smoothed, carefully
remove top paper.

Determining Proper Torque
LA
L
E
LA
LH
The only reliable method of creating a consistently
leak-free and long-lasting connection is to ensure the
coupling is brought to the proper torque. Using a torque
wrench with crowfoot is the best method, but the ats
method can be used if a torque wrench is not available.
The most straightforward method of determining the
correct torque setting is to multiply the desired torque
by the length of the wrench from the center of the handle
to the center of the drive (L); divided by the length of the
wrench from the center of the handle to the crowfoot
center (LA) as shown below:
L
Figure 2-16. Torque Wrench - Crowfoot
Information and Specications
2
The minimum torque values are
adequate for sealing most applications. Maximum
torque values should never be exceeded.
There are several methods of determining the correct
setting on the torque wrench when using a crowfoot. All
of the methods involve making the setting proportional
to the effective change in length of the wrench multiplied
by the desired nal torque. The equations and
illustration below describe proper measurements.
Equations
• Torque setting if the crowfoot is placed in line with
respect to the wrench:
• Torque setting if the crowfoot is placed at 90° with
respect to the wrench
• To estimate the crowfoot size (E)
TS = TD * L / LA
OR
TS = TD * L / (L+E)
TS = TD * L / LH
OR
TS = TD * L / √(L2 + E2)
Figure 2-17. Measurements Needed
LEGEND
L = Distance from center of torque wrench handle to the
center of socket drive
E = Distance from center of socket drive to the center of
crowfoot
LA = Distance from center of torque wrench handle to
the center of crowfoot
LH = Distance from center of torque wrench handle to
the center of crowfoot, when mounted at 90°
TD = Desired torque at the tting
TS = Torque setting indicated on wrench
E = Drive Size * 0.5 + Distance between Drive and
Open End + Wrench Size * 0.5774

Coupling Installation
Use the following steps for proper coupling installation:
1. Determine the correct torque value for your
coupling.
NOTE: Only use the torque values specied from
the manufacturer. DO NOT use SAE torque
recommendations.
2. Ensure the seal face and threads are clean and in
good condition. O-Rings should be lubricated with
light oil, but threads should be completely dry unless
making pipe thread connections (interference seal).
NOTE: Attach the male end of the hose onto the
equipment rst since it may be necessary to
rotate the entire hose assembly to tighten
the male threads. Then route the hose into
position while avoiding twisting the hose.
3. Tighten the connection (by hand), bringing the seal
face into contact and rotating the nut until it stops.
4. Mark a line across the coupling nut and backup hex
for the ats method verication of coupling torque.
5. Apply a wrench to the backup hex to prevent the
coupling and hose from moving while tightening the
nut with a torque wrench.
Failure to retain the backup hex during
installation will also result in additional clamp load
force that could cause damage to the seal face.
NOTE: The coupling nut must be in motion for an
accurate torque reading. If the nut is stopped
before nal torque value is achieved, it must
be loosened and retightened until the torque
is attained while the nut is in motion.
If a torque wrench cannot t into the coupling area or if
it is unavailable, the ats method may be used to ensure
that the coupling is properly tightened, as shown in the
following gure.
Example 2 Flats
difference
Figure 2-18. Flats Method Tightening
NOTE: The mark placed on the nut and backup hex
after tightening by hand should rotate during
nal tightening according to the table below.
The nut and backup hex can then be marked
to indicate if the coupling loosens over time.

1. Seal faces must be in contact with the tting fully
tightened by hand before marking ats.
2. The ats method is most accurate for the rst
assembly cycle. For multiple disassembly and
assembly cycles, torque values are more reliable.

Components Overview
This section describes the major components for the
LeeBoy 8515D Conveyor Paver. Become familiar with
these components before operating the machine.
Engine
The LeeBoy Model 8515D Conveyor Paver is equipped
with a Kubota, 74 HP (55.2 kW) diesel engine mounted
on standard heavy-duty vibration isolators. It is
accessible through several access doors on the engine
cover, especially the front service door mounted with
all fuel lter components for easier access. This paver
features improved visibility with a low-prole engine
cover along with easy access to engine relays and the
fuse panel.
The air cleaner removes ne particles such as dust,
sand, chaff and lint from the air. As air is taken into the
air cleaner assembly, the cyclone action deposits some
of the ne particles in the evacuator that is mounted on
the bottom of the air cleaner housing. The evacuator is
held closed during engine operation by suction. When
the engine is shut off, the weight of the debris opens
rubber aps, allowing the debris to fall out. These aps
can also be squeezed open for cleaning.
Hydraulic System
The hydraulic system includes hydraulic pumps, motor
and cylinders that work together for optimum machine
component control. Valves regulate the directional,
pressure and uid ow throughout the hydraulic system.
The LeeBoy 8515D Conveyor Paver now features
a hydraulic test ports for ease and convenience in
checking pressure for its ve main functions.
Torque Hubs
The paver drive system contains two torque hubs that
provide power to propel the tracks. Two-speed motors
power tough planetary drives for smooth operation.
Hopper and Conveyors
The hopper wings are hydraulically controlled to raise
and lower the hopper. When fully open, the hopper can
hold a payload up to 7.5 tons.
Material in the hopper is moved toward the back of the
paver to the screed by conveyors. The conveyor is
activated at the operator platform. Its wide, automatic
conveyors with a wide hopper design delivers asphalt
more evenly and efciently to produce a smooth asphalt
mat.
The hopper’s conveyor bed can be lifted hydraulically,
allowing easy access to the paver undercarriage and
tracks for service and cleaning.
3
The fuel lter removes contaminants from diesel fuel
before it ows into the injection pump where it is injected
into the engine combustion chamber.
The radiator mounted in front of the engine cools the
engine. As coolant ows through the radiator, airow
from the engine-driven fan removes heat.
Refer to the Engine Operator’s Manual accompanying
your paver for additional engine information.
Leeboy Model 8515D Conveyor Paver 3-3
Component Location
Augers
Right and left augers rotate
to move material from the
conveyors to the screed.
The auger can be manually
controlled at the operator
platform or by a screed
operator on the screed using a remote control box.
The auger can also be controlled automatically using
the auger sonic sensor system. The sensor is mounted
on the screed endgates and used to monitor and control
the pile height of material at the discharge end of the
augers.
Operator Platform
The operator platform allows easy and convenient
access for controls of most paver functions. The paver
can be operated from the left or right side depending
upon which control panel side is active and best suited
to the working conditions. Controls can also be lowered
to operate as a low deck or the high deck option with an
assistant standing on the screed walkboard.
Electrical System
The battery produces 12 volts DC and maintains 1,125
cold cranking amperes (CCA). An engine-mounted
alternator with a minimum of 60 amperes charging
capacity keeps the battery charged during normal
operation. The battery charge rate can be monitored
using the voltmeter on the center operator control panel.

Screed
The screed is the last part of the paver that contacts the
paving material. A screed operator usually operates the
screed while the operator drives the machine. Paving
material is fed from the hopper and conveyor to the
augers to the front of the screed.
The screed has hydraulically-controlled extensions that
move in and out to allow a paving base from 8 - 15 feet.
Screed heating is accomplished by either propane or
the optional electric heating elements mounted directly
to the wear plates.

4-2 LeeBoy 8515D Conveyor Paver
Operation
General Information
The LeeBoy Model 8515D Conveyor Paver is equipped
with steel hydrostatic-driven tracks that propel the
paver using friction-controlled joysticks. Each track is
powered by a single-speed motor directly coupled to
torque hubs. Standard LeeBoy hydrostatic controls
provide travel direction and steering capabilities from
either side of the paver. An optional steering wheel is
also available.
The two joysticks control the speed and direction of the
paver in conjunction with the machine speed setting.
The amount of steering is controlled by the amount of
joystick movement and the speed of the paver. As the
paver speed increases, steering will be reduced.
The two conveyors are the widest in the industry to
deliver asphalt more evenly and efciently to produce
a smooth asphalt mat. Two propane burners on the
main screed and a burner on each hydraulic screed
extension provide seamless mats at paving widths up
to 15 (4.6 m) feet. Electric screed heat is an additional
option. Cut-off gates under the auger offers the
operator precise control while paving and minimizes
clean-up at the end of pulls.
Read this manual carefully before operating the
machine. Only authorized personnel who are
properly trained should operate the LeeBoy Model
8515D Conveyor Paver.
Hopper Lock Pins
This machine is provided with hopper lock pins (one
on each side). (Figure 4-1) Extend the pins to prevent
the hopper wing from inadvertently leaking down during
transport. Retract the pin and lock down the thumb
screw during operation.

LeeBoy 8515D Conveyor Paver 4-3
Operation
Start-Up Procedure
DO NOT leave the operator station
unattended while the paver is in gear or in motion.
Operator must return joysticks to the neutral position
and turn the RUN/STOP switch to the STOP position
before leaving the operator platform.
Verify there are no people, obstacles
or other equipment in the machine’s path before
starting the engine.
1. Clear auger and conveyors before starting engine.
2. Position joysticks to NEUTRAL (center).
3. Insert key into the ignition and turn clockwise to
the START position. The “Wait to Start” light on the
control panel will illuminate.
4. Wait for the “Wait to Start” light to turn off, then turn
key to the RUN position to start.
DO NOT hold the starter longer than
10 - 15 seconds. If the engine does not start, allow
the starter to cool two or three minutes.
Using starting additives, such as
ether, is not recommended as severe engine damage
can occur.
5. Allow engine to warm up a few minutes before
moving paver for more efcient operation. In cold
weather let hydraulic oil warm to 60° (16°C) before
moving.
6. Set engine RPM using the throttle up and down
buttons on the Engine Screen on the digital display
screen.
DPF Regeneration (REGEN)
When starting the engine, a sequence of screens will
display on the PV480 digital display unit on the operator
console. (Page 4-5) First you will see “booting” notated
in the upper left corner, followed by a logo display, then
the gauge screen is displayed. The lit status icons at the
top of the screen will disappear momentarily.
This digital unit displays operational information,
diagnostics and other controls for the machine. It is
particularly important that the operator understand DPF
regeneration.
DPF regeneration is the term given to the cleaning
process where the exhaust temperature is raised in
an attempt to safely burn off any soot and undesired
combustion gas captured in the Diesel Particulate
Filter (DPF) in the exhaust system. When the DPF
lter reaches a soot saturation level between 25 - 45
percent, the onboard engine ECU (Engine Control Unit)
will activate a regeneration cycle.
To reduce the amount of particulate
matter and maximize efciency, use API-CJ4 (or
ACEA-E9 European equivalent) engine oil. Running
the engine at 1800 - 2000 RPMs will also provide
more efcient operation and allow automatic
regneration while paving.
During normal operation, the DPF is cleaned
automatically. Under certain conditions, the operator
may have to instruct the control system to perform the
cleaning process.
The DPF icon indicates the level of soot build-up on a
scale of Level 0 - 5 and changes color. Regeneration
will occur automatically at Level 1 - 2.
Stopping the Engine
1. Move joysticks to the NEUTRAL position.
2. Reduce engine to 1300 RPMs
3. Turn ignition key on instrument panel
counterclockwise to the OFF position and remove
key.
NOTE: If for any reason the engine does not shut
down when key is turned off, push in the E-Stop
button.
4-4 LeeBoy 8515D Conveyor Paver
It is important to perform a parked, manual
regeneration BEFORE the engine reaches as high as
Level 4. If the DPF reaches Level 4 - 5, non-warranty
factory assistance from the engine manufacturer is
required.
The engine speed will increase during regeneration
and there may be a noticeable sound difference. Once
regeneration is complete, the engine will return to
normal idle speed.
Once the DPF cycle has been activated, it is important
not to shut off the engine as the regeneration cycle
will fail and could possibly damage the engine. If the
regeneration cycle fails, the ECU may attempt a second
regeneration depending upon how blocked the lter
has become. If the system does not allow a second
regeneration, this means the lter is blocked more than
80 percent and needs to be cleaned or replaced.

NOTE: To perform a Parked REGEN, the “P” and “N” lamps must be illuminated.
Engine Exhaust High Temperature Lamp — This lamp illuminates during the REGEN cycle to warn of
high exhaust temperatures. This lamp will turn off when normal operating temperatures are reached
after the REGEN cycle.
Be sure engine exhaust is away from any potentially combustible materials
when this is illuminated.
Diesel Particulate Filter Lamp — A Solid Lamp is the initial warning that soot levels are rising in the
DPF. A Flashing Lamp indicates a DPF REGEN is needed (on some systems, the lamp will become
RED when ashing). The lamp will turn solid again when a REGEN is initiated.
Any time the lamp begins ashing, the operator should increase the loading on the engine so that
regeneration is possible.
If increased load does not cause an automatic REGEN to occur, the operator
should immediately perform a Parked, Manual REGEN (see reverse side for instructions).
DPF Regeneration set to Inhibit — The user may choose to inhibit the REGEN if conditions are
too hazardous for high exhaust temperatures. When this lamp is illuminated, a REGEN cannot be
performed and soot levels will continue to rise.
Unless hazardous conditions exist, the REGEN Inhibit switch and this lamp
should remain off.

Steering and Speed Control
Use the dual joysticks for steering and speed control. It
is important to move the joysticks SLOWLY. The RUN/
STOP switch applies parking brake when set to the
STOP position. (Figure 4-30)
Rapid counter-rotation in either
direction can result in the operator being thrown
from the machine and suffer personal injury or
death. Counter-rotation occurs if one joystick is in
the extreme forward position and the other is in the
extreme rear position while the machine is in gear
and moving. Make only slow adjustments to joysticks
or steering wheel to turn machine.

The operator control panel contains paver function
switches with main controls in the center. (Figure 4-29)
Figure 4-29. Operator Station
• Place both joysticks in the neutral position on the side
being deactivated. (Figure 4-30)
• Move the RUN/STOP switch to the STOP position.
• Follow the start-up procedure. (Page 4-4)
Ensure there are no people, obstacles
or other equipment in the path of the paver before
moving in either direction.

NOTE: To slow the paver, move joysticks closer to
the neutral position.
NOTE: To stop the paver, pull joysticks back to the
neutral position.
• To drive the paver forward, lift up on the joysticks and
push forward to reach the desired speed.
• To move in reverse, lift up on the joysticks and move
backwards to reach desired speed.
• Return joysticks to the neutral position to stop paver.
• To steer the unit to the left, SLOWLY push the right
joystick farther forward than the left joystick. The
farther the joystick is pushed, the more the paver
turns. Slow and easy adjustments are required for
safe operation.

Operation
• To steer the unit to the right, SLOWLY push the left
joystick farther forward than the right joystick. The
farther the joystick is pushed, the more the paver
turns. Slow and easy adjustments are required for
safe operation.
NOTE: If the joysticks are in the forward position
and the Run/Stop switch is set to the STOP
position, the system will time-out after 10
minutes. You must put joysticks back into
neutral and toggle the Run/Stop switch from
RUN to STOP and back to RUN again to regain
control. (See Page 5-31 for more information
about this safety feature.)
Stopping the Engine
1. Place joysticks to the neutral position.
2. Throttle back to idle using settings on the digital
display screen.
3. Turn ignition key on the instrument panel
counterclockwise to the OFF position and remove
key.
NOTE: If the engine does not shut down when key is
turned to OFF, press the E-Stop button on the
control panel to terminate power.
Before leaving the operator platform,
the operator must return joysticks to the neutral
position and switch the Run/Stop (on the Steering
and Speed Control Box) to the STOP position.
Paver Operation
Spray Down
Always spray down the LeeBoy Model 8515D Conveyor
Paver before and after paving. Spray clean with solvent
or release agent on any part of the paver that comes into
contact with asphalt to prevent buildup that will damage
the machine over time.
There is a spray down system on both sides of the
Leeboy 8515D paver for your convenience. The wand
is conveniently located on each side of the operator’s
station. (Figure 4-31) The hose reel is located inside
the panel.
1. Turn the Spray Down switch on the control panel
ON. (Pages 3-6 to 3-7)
2. Extend hose from the reel.
3. Squeeze the wand handle and spray area. Release
the wand handle when nished.
4. Turns the Spray Down switch on the control panel
OFF.

Heating the Screed
Heating the screed helps prevent hot mix from sticking
to the cold screed plate and produces a smooth, tight
mat surface. This should be performed before paving
and if the paver is idle long enough for the screed to
cool between loads.
Allow the screed (and screed extension) to heat 15
minutes before beginning to pave.
NOTE: Lower the screed two inches off the ground
while heating to prevent cold air and wind
from affecting the heating process.
NOTE: You can set the screed directly onto a fresh
mat of hot asphalt while running the heating
system, allowing the heat of the asphalt to
help heat the screed plate.
Overheating the screed can warp the
screed plate and possibly cause damage. If screed
extensions lock, allow the machine to cool before
attempting to extend or retract. Replace a warped
screed plate immediately.
The standard LeeBoy Model 8515D Conveyor Paver is
equipped with two propane burners on the main screed
and one burner on each screed extension. An electric
heat option is also available. (Page 4-21) An optional
815HD (Heavy Duty) screed features additonal heating
elements and heating options (Page 4-35).
Never open a valve to a burner unless
ame is present. A buildup of unburned gas could
result in a gas explosion.
Propane gas used to heat the screed
is volatile and combustible. Use extreme care to
prevent burns or other injury.
To light the burners:
1. Ensure ALL propane heat valves are closed by
turning valves clockwise (propane tank, main burner
valves, main ignitor valve, extension ignitor valves).
(Figures 4-32 and 4-34)
2. Turn the propane tank Open/Close valve
counterclockwise to open the propane gas ow.
(Figure 4-33)

Reduce pressure on the propane pressure
regulator gauge to two pounds (.14 bar) in
these conditions. DO NOT attempt to regulate
the burner with the burner valve.
After the main screed (and screed extension) has
heated for 15 minutes:
1. Turn the propane tank valve clockwise to the
CLOSE position to allow the propane system to
burn off all the gas. (Figure 4-33)
2. When the ames extinguish, TURN OFF ALL burner
valves clockwise to the OFF position. (Figures

Electric Screed Heat (Option)
The LeeBoy 8515D Conveyor Paver offers an optional
electric heat system to heat the screed, including the
screed extensions, in lieu of the burner system. A
hydraulically-driven generator powers the electric heat
control box mounted in the center on the rear side of the
machine. This control box is where you will select the
heating function before you begin to pave. It is easily
accessible to the screed operator when a heating cycle
is needed. (Figure 4-36).

Once the heating function has been enabled, the
distribution/control box will apply electrical power to the
heating elements and the heating cycle will begin. The
heating cycle is timed to optimize the heat generated at
the screed plates.
Running the engine 2200 RPMs
to heat the screed provides the best operating
conditions. Running the engine at lower RPMs
will not allow the screed to heat correctly and may
damage the generator.
To operate the electrtic screed heating system:
1. Start the paver and idle until the engine reaches
normal operating temperature.
2. Set the throttle to normal operating speed (1800 to
2200 RPMs).
3. Raise the screed plate one or two inches off the
ground.

Hopper Wings
The hopper wings are hydraulically opened so the
hopper can be lled with paving material. (Figure 4-38)
Conveyor paddles in the bottom move the asphalt back
to the auger, where the mix ows through the cut-off
gates to the screed.
To operate the hopper wings:
1. Push the hopper wings switch to OUT on the
operator control panel to fold out hopper wings.
(Pages 3-6 to 3-11)
2. Be sure the hopper wings are completely extended
before receiving paving material from the truck.
3. Push the hopper wings switch to IN to close the
hopper wings.
DO NOT fold in the hopper wings when
the hopper is full of asphalt. DO NOT fold in the
hopper until the material truck has moved completely
away from the paver. Never raise the conveyor bed
with asphalt in the hopper.

Operation
Conveyors
The LeeBoy Model 8515D Conveyor Paver is equipped
with two automatic conveyors that deliver asphalt evenly
to produce a smooth asphalt mat. (Figure 4-39)
The conveyor is a very important part of the paver that
moves material from the hopper back to the auger
and out of the cut-off gates to the screed. Pay close
attention to integrating its operation into the total
operation of the paver.

2
Figure 4-39. Conveyor Chains and Paddles
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.
(Pages 3-6 to 3-11)
• 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.
Hydraulic Cut-Off Gates
The cut-off gates are another important function of the
paver. The cut-off gates are used primarily to control
the ow of asphalt to the screed and hydraulic screed
extensions. Cut-offs can be used to limit material ow
when making narrow passes at the beginning and
ending of each pass or pull. Proper use of the cut-off
gates minimizes clean-up at the end of pulls. (Figure
4-40)
• The right and left cut-off switches on the manifold
open and close the cut-off gates.
• Holding the switch in the OPEN positions increases
asphalt ow to the screed. Holding the switch in
the CLOSED position decreases asphalt ow to the
screed.

• 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.

Screw and Endgate
Use the screed extensions when paving widths
exceeding eight (8) feet. The screed extensions should
be heated before making any adjustments. Use the
wrench provided to make adjustments. When adjusted
correctly, pressure on the rear edge of the extended
screed is the same as the rear edge of the main screed,
resulting in a smooth mat the length of the screed.

NOTE: Never allow the endgate to carry the weight of
the screed to prevent uneven compaction.
7. If the endgate digs into the asphalt at the front,
adjust the tilt screw until the endgate tilts back more.
8. When making a hot joint, the endgate must be set to
where it ts ush with bottom of screed.
9. On the rst pass, leave approximately six to eight
inches (15 - 20 cm) of unrolled asphalt where the
joint will be made.
10. When making a joint, the endgate must be set to
where it ts ush with bottom of screed.
Adjust the screed extension while paving using the
following procedures:
1. Move paver to the starting position for paving.
2. Extend the screed to the desired width.
3. To set the depth, you can place small starter blocks
under the main screed while you make adjustments.
(Figure 4-45)
Figure 4-45. Starter Blocks Location
4. Level the screed using the electric ight screw
gauge (Figures 4-41 and 4-42).
• Refer to the elevation gauge (one on each side
of the paver for your convenience). Raise or
lower until the rod end of the cable is ush with
“0” on the gauge.
• While paving, refer to both gauges and make
minor adjustments if needed.
5. On the rst pass, turn the endgate depth screw to
lower the endgate until it is about 1/4-inch (6.35 mm)
below the screed. (Figure 4-43)
6. Turn the tilt screw so the front of the endgate tilts
down slightly when the screed is lifted. This will allow
the endgate to set itself to the grade. (Figure 4-46)

Figure 4-46. Endgate Tilt Screw Adjustment
NOTE: Keep runners clean. When making a joint,
spray solvent on the runners.
11. If the joint looks too high or too low, adjust the ight
screw on the screed one turn at a time and allow
four to ve feet (1.2 - 1.4 m) of travel to correct itself.
NOTE: Too much adjustment up or down may cause
uneven pavement.
12. If making a cold joint, set the endgate down about
1/4 inch (6.35 mm) for a nice, even edge.
LeeBoy 8515D Conveyor Paver 4-25
Operation
Sonic Auger Sensor
The sonic auger controls the amount of material owing
to the endgates, gauging the amount of paving material
in the extensions. An operator can operate the sonic
auger from either side of the paver. The sonic auger
sensors are not used in the manual mode. (Figure
4-47)
A sonic auger sensor connects from the paver to the
screed. It detects the material height and controls the
auger height by automatically turning the auger on and
off.
The sonic auger sensors are most often used when
paving widths of nine to 15 feet (2.7 - 4.6 meters).
NOTE: The augers are not needed when paving under
eight-feet wide (2.4 m).
To operate the sonic auger sensor
1. Set the left and right auger switches on the left side
of the control panel to AUTO. (Pages 3-6 to 3-9)
2. Set the left and right auger switches on the right
side of the control panel to the SLAVE position.
3. Set the left and right auger On/Off switch on the
remote control box to ON. (Figure 4-44)
4. Adjust material height at the endgate using the
auger dial beside the steering control box. (Figure
4-48)
• The right and left auger dials controls material
height. Turning the dial clockwise increases
material height while turning counterclockwise
decreases material height.
• When the material height moves into the
sonic range, the auger speed will slow down
proportionately and turn off. It will turn back on
when the material level drops.

Operation
Starting to Pave
The LeeBoy 8515D Conveyor Paver provides superior
paving for driveways, small to large parking lots, and
secondary roads. The paver is equipped with electric
and manual thickness controls, and can be operated
from either side of the operator platform. It has a
production rate of approximately 250 tons per hour.
Figure 4-49. Paving
This paver is capable of placing a mat thickness of six
inches (20 centimeters) for:
• Bituminous base.
• Binder or surface course.
• Lime or Portland cement-stabilized sub-base.
• Use a reference guide such as a curb, gutter, adjacent
mat or string line.
• It is very important that the rst pass be straight as it
will serve as your guideline for the following passes.
• Extend the lower guide bar gauge to further assist you
in paving a straight line from the operator’s station.
(Page 4-50)
4
Guide Bar
Figure 4-50. Lower Guide Bar Gauge
Avoid low limbs, power lines, and
other objects that can endanger crew or paver.
• Graded aggregate materials.
Operators should be trained to operate the various
machine components along with proper paving
techniques before operating the machine.
Before starting to pave, keep these items in mind:
• Plan the project so you pave the most narrow passes
rst (the width of the paver), leaving the widest passes
until last.
• Always pave in low range.
• It is the operator’s job to guide the material truck
back to the hopper and signal the driver when to stop
dumping the asphalt into the hopper. The driver must
maintain a light pressure on the brakes to prevent the
truck from dumping asphalt onto the ground.
NOTE: If paver is equipped with the optional truck
hitch, the truck driver will not be required to
maintain brake pressure. (Page 4-33)
Basic Paving
1. Position paver at the starting point for the mat.
(Operate the paver from one side only.)
2. Open cut-off gates under auger. (Page 4-23)
3. Adjust screed as needed. (Page 4-24)
4. Open hopper wings to accept asphalt from the
material truck. (Page 4-22)
NOTE: Allow only a partial load of asphalt to enter the
hopper when rst starting to pave.
6. Turn the left and right conveyor switches to the
AUTO position.
7. When the material begins to discharge from under
the screed, set the screed lift switch to the FLOAT
position. (Pages 3-6 to 3-11)
8. If paving a width more than eight feet, turn the left
and right auger switches to AUTO to control the
material height at the endgate. (Augers aren’t
needed when paving a basic eight-foot pull.)
(Pages 3-6 to 3-11)
LeeBoy 8515D Conveyor Paver 4-27
Operation
9. When the material starts moving into the sonic
range, the sonic auger will automatically regulate
the auger operation.
NOTE: The material height must be set to the highest
point when the endgates are closed. When
the endgates are open, the material height will
lower to prevent material from pushing in front
of the endgates.
10. Begin paving, moving slowly at rst to adjust the
screed if needed.
11. Make a paving pass until the asphalt level in the
hopper is low.
NOTE: To prevent excessive handwork, set the left
and right conveyor conveyor switches to the
OFF position and set both cut-off switches to
the CLOSE position about three feet from the
end of the pull to prevent excessive handwork.
12. Return paver back to starting position to begin the
next pull.
13. Position and set the screed endgate on the joint
side back to “0” feet, or ush with bottom of the
screed.
Never back up with cut-off gates open.
Setting the Crown
The screed can also be set to control the pavement
slope, or crown. A pavement crown is the elevation of
the middle in relation to the edges, and insures proper
drainage of the pavement.
To adjust the crown:
1. Loosen the lock-down bolts in slotted bars before
adjusting crown and valley mechanism. (Figure
4-51)
14. Repeat these steps as you continue to pave.
Figure 4-51. Loosen Lock-Down Bolts
2. Remove the crown handle and insert into adjuster.
(Figure 4-52)
3. For increased positive crown push down on
adjuster.
4. For increased negative crown pull up on adjuster.
5. Use the gauge at the center of the screed above the
standing platform. If the needle is above the zero,
you will have positive crown. If the needle is below
the zero, you will have negative crown.
6. To get exact crown or valley, measure the distance
between a at level surface to the center bottom
portion of screed. Make adjustments with crown and
valley control.
NOTE: Maximum crown is two inches.

• Positive crown is when the middle of the mat is raised
to permit water to drain to each side.
• Negative crown is the lower in the center of the
screed plate, often used in an alley where drainage is
necessary.
Operation
Mat Texture Adjustment
Spray the bottom of the screed with cleaning solvent

BEFORE heating the screed. The screed extension
should be hot before making any adjustments. The
screed can be adjusted for a smoother or coarser mat
texture by using the Angle of Attack (AOA) adjustment
screw. (Figure 4-54)
NEVER spray cleaning solvent or
release agnet on or near a screed heating element
that is hot or being heated. Do not spray near open
ame or ignition source. Cleaning solvent and
release agents are ammable and could cause
serious personal injury.
NOTE: Consider the environment when using
solvents and release agents. Do not allow
these chemicals to run onto the ground.

Figure 4-54. AOA Adjustment
There are three adjusters in each extension. The two
adjusters at each end of the screed extensions are
preset by the dealer and should not need adjustment.
Figure 4-53. Crown Settings
1 - Positive (+)
2 - Zero (0)
3 - Negative (-)
NOTE: Crown may be placed in the leading edge and/
or the trailing edge of the screed plate. Crown
in the leading edge aids material ow under
the screed plate only. Trailing edge crown
puts a crown in the mat.
Example: The trailing edge crown is 0 and the
leading edge crown is 1/8 inch. There will not be
any crown in the mat, but the material ow under the
screed plate will be improved.
LeeBoy 8515D Conveyor Paver 4-29
You can adjust the mat texture using the AOA
adjustment screw in the center.
Increasing pressure on the back of the screed
extension will result in a smoother, slicker nish.
Decreasing pressure will result in a more coarse nish.
Too much pressure on the back of the screed extension
will take the weight off the screed wearplate and cause
poor material compacting, resulting in a poor nish in the
center of the main screed.
Operation
To make the AOA adjustment:
1. Spray down the screed.
2. Turn on the screed heat.
3. Turn the AOA adjuster in the direction for desired
result:
• Turning the AOA adjuster counterclockwise
will increase the pressure on the back of the
extension, which gives a smoother, slicker
nish.
• Turning the adjusters clockwise will decrease
the pressure on the back of the extension,
resulting in a coarser nish.
NOTE: Too much pressure on the back of the
screed extension will take the weight off the
screed wearplate and cause poor material
compacting, resulting in a poor nish.
815HD Screed Extension Double
Adjustment (Option)
There are also three adjusters on the optional 815HD
screed extensions. (Page 4-35) If equipped with this
option, the two covered adjusters on each extension
(one on each side of the AOA adjuster) are for vertical
adjustment. (Figure 4-55) The vertical adjusters
are preset by the manufacturer and should not need
adjustment.
Follow the same procedures for the AOA adjustment if
equipped with the 815D screed extension option.

Unloading and Loading
Ensure the transport trailer has the capacity to carry
the paver’s weight. Park the trailer in a clear, level area
when loading or unloading the machine.
ALWAYS position an assistant to be a
ground guide when loading and unloading the paver.
Work slowly and carefully to avoid
accidents. Keep the loading area clear.
Unloading
1. Remove tie-down equipment.
2. Start and warm up engine.
3. Set throttle at half the operating RPMs, but enough
to ensure the hydraulic pump is providing sufcient
ow to operate all functions properly.
4. Set steering control lever so paver moves very
slowly.
5. BEFORE moving the machine, ensure:
• The screed position is UP.
• Auger extensions are removed.
• The extendible screed is IN.
• The cut-off gates below the augers are
CLOSED.
6. Move paver forward down the ramp as shown on
Figure 4-56.
Never move the paver in reverse while
the cut-off gates are open.
DO NOT allow the screed to strike the
ramp as this can damage bearings on the thickness
control screws or welds on the leveling arms. A
longer ramp to reduce the loading angle may be
needed.

Optional Components
Auger Extensions Option
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 feet (4.6 m). This makes it possible to lay asphalt
at a higher rate. Auger extension options are 12-inch
extensions for each side or 24-inch extensions with
shields for each side.
Left and right auger extension covers
or shields must be installed on the correct side of the
machine.
To attach the auger extensions proceed as follows:
1. Identify the right and left auger extensions by
observing the left or 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:
• Set the left and right auger switches to the OFF
position.
• Set the left and right extension switches to the
OUT position and extend fully.
Screed Sloping Extensions
The sloping extensions option provides the means of
matching curb and gutter to reduce handwork while
paving. (Figure 4-60) The hydraulic slope extensions
provide 0 - 8 percent slope.
Figure 4-60. Screed Sloping Extensions
Steering Wheel Option
A steering wheel option is also available in lieu of
joystick steering and direction/speed controls.
(Figure 4-61) The Run/Stop switch on the steering
panel controls running and stopping the machine.

3. Shut off engine.
Serious injury can result when
attaching extensions if the engine is running.
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.
Umbrella Option
The umbrella kit option provides shelter from sun and
other weather conditions for the operator. The umbrella
kit assembly includes the mounting bracket and
umbrella frame assembly that can be mounted on either
side of the screed handle.

Operation
Truck Hitch Attachment Option
The truck hitch is an optional attachment that prevents
excessive and uneven braking from the paving material
truck. (Figure 4-62)
Figure 4-62. Truck Hitch Attachment Option
To engage the hitch with the rear wheels of the asphalt
truck:
1. Set the Truck Hitch selector lever to TRUCK
HITCH. (Figure 4-63) (If the lever is set on
CONVEYOR, it will raise and lower the conveyor
bed.)
2. Extend the arm extensions of the truck hitch by
pushing and holding the Truck Hitch button in the
OUT position.
3. The paving material truck then SLOWLY backs up
to the paver until the hitch makes contact with the
rear tires of the truck.
4. Retract the arm extension by pushing and holding
the Truck Hitch switch in the IN position until both
guide rollers are fully locked onto the truck wheel
rims.
NOTE: It may be necessary to adjust the roller
guides to the inside of the wheel rims.
Electric Screed Options
The Legend Propane Screed is standard on the 8515D
paver, complete with propane burners on the main
screed and one burner on each screed extension.
Electric screed options are also available and include
an electric heat control box powered by a hydraulicallydriven generator. The Electric Legend Plus Screed
features electrically-heated main and screed extensions
and dual vibrators, and is equipped with replaceable
wear shoes.
The Legend 815HD Electric Screed option offers
numerous features for paving professionals. The main
screed and screed extensions are electrically heated by
six (6) 1000-watt and one (1) 1240-watt blade elements
(four 1000-watt and one 1240-watt on the main screed
and one 1000-watt on each screed extension). It is
equipped with replaceable, heavy-duty wear plates.
Dual vibrators, heavy-duty ight screws, heavy-duty
crown and valley mechanism, and a 3-Adjuster screed
system featuring AOA and vertical height adjustment
add even more screed control. Other options available
for this screed include heated endgates.
Power Crown Option
The Power Crown option automatically adjusts the
positive or negative crown as needed. (Figure 4-64)
The power crown option can only be used on the right
screed extension. The selector valve is located on the
right screed extension control cover. Move the selector
valve to the left for crown and to the right for normal
screed operation.

815HD (Heavy Duty) Electric
Screed
The optional 815 HD screed is sturdier, heavier and
easier to rebuild. This enhanced screed option can
include power crown, ight screws and electric heating
system (with ve heating elements on the main screed
and one on each hydraulic extension). The sonic auger
mount has adjustable positions. The 815 HD screed
offers two options within this option for even more
robust screed operation: Heated Endgates and Heated
Edge Endgates.
Heated Endgates
The heated endgate
also heats the edge of
the endgate, producing
a smoother joint as you
pave. (Figure 4-66)
(When the heated endgate
is turned on, the leading
heating element turns off
on the side you’re heating.)
With the heated endgate
option(s), additional

Track Tension Pressure Relief
The hydraulic adjustment cylinders are automatic and
provide even tension on the tracks to prevent excessive
wear to the paver’s undercarraige. The track tension
main manifold is mounted on the back side of the lower
hydraulic tank in the conveyor bed.
The track hydraulic pressure is set at 1500 PSI at the
track tension main manifold.
To check pressure, locate the track tension main
manifold in the conveyor bed and perform the following
procedures:
1. Raise conveyor bed. (Page 5-4)
2. Connect a 2000 PSI gauge inline with either Port
A or Port B on the track tension main manifold.
(Figure 5-10)
3. Place a Porta Power between the front idler and
frame to release pressure on the idler.
4. Increase the Porta Power pressure until the front
idler cylinder compresses.
5. Pressure should read 1500 PSI.
Conveyor Switch Adjustment
Small adjustments may be necessary to conveyor
switch for optimum conveyor performance. (Figure
5-11)
There are two positions of the conveyor ap: One upper,
shutting the conveyor OFF; and one lower, turning the
conveyor ON.
Check Adjustment
1. Remove the upper walkboard grate.
2. Raise the conveyor ap 6-1/2 to 7 inches (16.5 to
17.8 cm) from the bottom of the tank mount support
and insert the safety prop.

6. If the pressure is not correct, remove cap on the
relief cartridge valve. Using an allen wrench, adjust
the relief cartridge valve IN for more pressure or
OUT for less pressure until the PSI gauge reads
1500 PSI.
7. When the pressure guage reads 1500 PSI,
disconnect Porta Power and gauge.
Do not tamper with the adjustment
part of the relief cartridge valve.

required to the upper ap.
Adjust Conveyor Switches
If the conveyor switch did not click OFF, adjustment is
needed:
1. Remove the linkage attaching the actuator arm to
the eyelet on the ap pivot housing.
2. Loosen Setscrew A on the actuator arm. (Figure
5-12)
3. Reposition this arm by either rotating it clockwise
or counterclockwise, depending upon where the
conveyor switch clicked OFF during the conveyor
ap upward travel.

4. When the switch clicks OFF, tighten setscrew and
reconnect linkage.
Maintenance
5. Repeat procedure for the lower ap.
If the lower ap switch did not click OFF:
1. Loosen Setscrew B. (Figure 5-12)
2. Slide the actuator arm IN or OUT bo bring the travel
limits into tolerance.
3. This may require several adjustments before the
correct position is obtained.
4. When the actuator arm is in the correct position,
tighten Setscrew B.
NOTE: The factory setting is one inch (2.54 cm) from
the center of Setscrew B to the eyelet on the
actuator arm.
NOTE: The setting from the factory is 1 in. (2.54 cm) from
the center of the setscrew “B” to the eyelet on
the actuator arm.
5. To bring the travel limits into tolerance, slide the
actuator arm in the direction desired. This may
require several adjustments before the correct
position is obtained. When the actuator arm is in the
correct position, tighten setscrew “B”. No further
adjustment is necessary.
Torque Hub Hydraulic Motor
Gear Adjustments
Torque hub hydraulic motors are
calibrated and set at the factory. These adjustment
should only be performed by an authorized LeeBoy
dealer. Work not performed by an authorized dealer
can damage machine and void the warranty.
The low gear adjustment must be made to the slow
side drive motor only. The low gear adjustment screw
is located on the bottom of the drive motor. Make only
small adjustments at a time.
Your authorized LeeBoy dealer will perform the tracking
adjustment on the high side gear by adjusting the screw
on the top of the hydraulic motor. This adjustment on the
motor for the fast track must be screwed in to equalize
track speed.
Your LeeBoy dealer will perform the following
procedure to adjust either gear:
1. With paver running, push the 2-Speed switch:
• Set both 2-Speed switches on both sides of the
control panel to the LOW position if adjusting
low gear. (The red 2-Speed light should not
illuminate.)
55
Setscrew A
Setscrew B
Figure 5-12. Actuator Arm - Setscrews A and B
• Set either 2-Speed switch to the HIGH position
if adjusting high gear. (The red 2-Speed light
will illuminate.)
2. Adjust screw (on bottom of the hydraulic motor for
low gear; on top for high gear) until you feel back
pressure on the adjustment screw. This indicates
the correct adjustment is close.
3. Finalize adjustment by making a one-quarter
(1/4) turn at a time until the correct adjustment is
accomplished. Recheck tracking.
NOTE: If hydraulic motor has not been previously
set, ten revolutions of the adjustment screw may be
required before noticing any difference in travel.

Engine Maintenance
The LeeBoy 8515D Conveyor Paver features the
latest in engine technology. Tier 4 engines comply
with emission requirements established by the U.S.
Environmental Protection Agency (EPA) to reduce diesel
particulate matter (DPM) and other toxins released into
the air. As part of the Clean Air Rules of 2004, the EPA
requires engine manufacturers to integrate controls into
systems that reduce exhaust emissions by 90 percent.
Advanced emission-control devices and low-sulfur fuel
requirements--only Ultra-Low Sulfur Diesel (ULSD) can
be used in these engines--combine with new aftertreatment methods such as Exhaust Gas Recirculation
(EGR) and Diesel Particulate Filters (DPF). These
general maintenance procedures are most often
required for the engine. Refer to the Engine Operator’s
Manual for more specic maintenance information and
procedures.
You can access the engine and other components via
the access panel in the hopper (Figure 5-13) or via
the operator platform. Some components can also be
reached from either side of the machine.
Check Engine Lubrication Oil
The engine lubrication oil must be kept at a level above
the ADD mark, but not above the FULL mark, on the
engine lubrication oil dipstick. (Figure 5-14)
DO NOT check the oil while the
engine running. Hot oil can spew and cause serious
personal injury.

To check the engine lubrication oil level:
1. Park the machine on a level surface and turn off the
engine.
2. Wait ve minutes to allow the oil to return to the oil
pan so you can obtain an accurate measurement of
the engine oil level.
3. Clean the area around the engine oil dipstick before
removing it from the engine.
4. Remove the dipstick from the engine and checking
the oil level. The oil level should be above the
ADD mark--but not above the FULL mark--on the
dipstick.
5. Add oil if needed.
