MACHINE PRECAUTIONS

Safety

The safety messages that follow have NOTICE level

hazards.

Any part that is found defective as a result of inspection
or any part whose measured value does not satisfy the
standard or limit must be replaced.

Always tighten components to the specied torque.
Loose parts can cause damage to the LeeBoy 8510E
Conveyor Paver or cause it to operate improperly.

Only use replacement parts approved by LeeBoy. Other
replacement parts may affect warranty coverage.

Follow the guidelines of the EPA or other
governmental agencies for the proper
disposal of hazardous materials such as
engine oil, diesel fuel, and engine coolant.
Consult the local authorities or
reclamation facility.

Dispose of hazardous materials in accordance with
all applicable laws and regulations. Never dispose of
hazardous materials by dumping them into a sewer, on
the ground, or into groundwater or waterways.

Clean all accumulated dirt and debris away from the
body of the paver and its components before you
inspect the paver or perform preventive maintenance
procedures or repairs. Operating a paver with
accumulated dirt and debris will cause premature wear
of paver components. Accumulated dirt and debris also
hinders effective paver inspection.

Retrieve any tools or parts that may have dropped inside
of the paver to avoid improper paver operation.

If any alert indicator illuminates during paver operation,
stop the engine immediately. Determine the cause and
repair the problem before continuing to operate the
paver.

Hot Material Precautions

• Wear protective gear for face, hands, feet, and body
when operating the paver.

• Allow machine to cool before repairing or maintaining
working components.

• If hot asphalt touches skin, ush area immediately with
cold water. DO NOT apply ice to the affected area.
DO NOT ATTEMPT TO REMOVE ASPHALT CEMENT
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

sufcient to penetrate the skin, which could cause
serious personal injury. Ensure all pressure is
relieved before disconnecting line, hoses or valves.

1

• 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.

LeeBoy 8510E Conveyor Paver 1-7

Safety

Refueling Precautions

• Do NOT overll the fuel tank as overow 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.

• Check brakes, steering and other control devices in
accordance with instructions before starting. Be sure
both steering levers (joysticks) are in neutral.

• DO NOT bypass the paver neutral-start system.

DO NOT operate the engine in an
enclosed area without proper ventilation. Exhaust
gasses are odorless and deadly.

Parking Precautions

• Park paver on level ground whenever possible, set

steering levers in neutral and lock. Apply the parking
brake. Park the paver securely blocked on grades.

• Before leaving operator’s station:

1. Place joysticks in neutral and lock in place.

2. Turn off all accessories.

3. Throttle back to idle.

4. Lower screed to ground.

5. Shut off engine.

• Remove ignition key when leaving paver parked or

unattended.

Operating Precautions

• 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.

• Always comply with local regulations regarding
moving equipment on public roads and highways.

• Know and use the hand signals required for a
particular job. Know who has the responsibility for
signaling.

• Make sure that all lights and reectors comply with
state and local regulations. Make sure that they are
clean, in good working order, and can be seen clearly
by all trafc.

• DO NOT stand between the equipment and the truck
while the truck is being backed to the paver. Death or
serious injury can result from being crushed between
the two machines.

• DO NOT ride on attachments.

• Check all gauges and warning instruments for proper

operation. If malfunctions are found, shut down the
machine and report the problem for resolution. If the
failure causes loss of steering control, loss of brake
control, or loss of engine power, stop paver motion as
quickly as possible. Apply parking brake. Keep the
machine securely parked until the failure is corrected
or the machine can be safely towed.

Safety

• Drive the machine with care. Make sure speed is
compatible with conditions. Use caution on rough
ground, slopes, and while turning.

• When moving the machine, adjust speed and direction
of travel for the terrain and ground conditions present.
Always consider adjusting travel speed to match
ground conditions.

• Be alert for hazards and obstructions such as ditches,
trees, cliffs, overhead power lines, and areas where
there is danger of a slide.

• Be aware of and understand the job site trafc ow
patterns.

• Obey agmen, road signs, and signals.

• Watch for bystanders. Never allow anyone to be

under the machine during operation. Never allow
anyone to reach into the machine during use.

• Operator must know how to use signaling devices
when operating paver in trafc conditions. Operator
must also understand which circumstances require
use of each signal. Use tail lights, slow-moving vehicle
signs, and warning beacon as needed when traveling
on public roads. It is recommended that you provide
an escort on the road.

• DO NOT tow the paver, except to remove from road or
to load on trailer.

Storage Precautions

• Store paver in an area away from human activity.

• DO NOT permit children to play on or around the

stored machine. Serious injury or death can occur
from improper/unauthorized use of the machine.

• Make sure the unit is stored on a surface that is rm,
level, and free of debris.

• Store the machine inside a building or cover securely
with a weatherproof tarpaulin.

Maintenance Precautions

• DO NOT attempt repairs unless trained to do so.
Refer to manuals and experienced repair personnel
for help.

• Before working on the machine, securely block the
machine and any components that may fall. Block
any working components to prevent unexpected
movement while repairs are being made.

• Always wear safety glasses and other required safety
equipment when servicing or making repairs.

• Disconnect battery before working on the electrical
system.

• Avoid lubrication or mechanical adjustments while the
paver is in motion or while engine is operating.

Poor Visibility

Increasingly, asphalt maintenance equipment is used
during less than ideal lighting conditions such as fog
and smog or at night. These conditions present safety
hazards for workers, bystanders and passing trafc.

When operating under restricted light
conditions, equip the machine with special lighting to
prevent serious injury.

While the machine is equipped with a beacon and a
work light, contact your authorized LeeBoy dealer for
additional lighting packages if working under these
conditions.

Use reective tape on the sides of machines when
working at night. Ensure all workers wear reective
safety vests. Use impact barriers (movable or
stationary) to protect workers and direct the trafc ow
safely away from the work site.

• If lubrication or mechanical adjustment is necessary,
use extreme caution and complete the following
steps:

1. Place Forward/Reverse control in neutral.

2. Apply neutral lock.

3. Lower screed to ground.

4. Shut off engine.

5. Place equipment in a safe position.

6. Securely block wheels and tracks.

• Never make repairs on pressurized components such
as uid lines, the gas system, or mechanical items until
the pressure has been relieved.

• When servicing or replacing hardened pins, use a
brass drift or other suitable material between the
hammer and pin.

• Keep brake and steering systems in good operating
condition.

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 2-14. Torque Wrench - Crowfoot

Information and Specications

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. (Use

LEGEND under Figure 2-4)

Equations

• Torque setting if the crowfoot is placed in line with

respect to the wrench:

TS = TD * L / LA

or

TS = TD * L / (L+E)

• Torque setting if the crowfoot is placed at 90° with

respect to the wrench

TS = TD * L / LH

or

Figure 2-15. 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

TS = TD * L / √(L2 + E2)

• To estimate the crowfoot size (E)

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 specied 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 verication of coupling torque (

12).

Terminations

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 tables.

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.

3. Tightening two (2) ats or more may damage seal
faces.

Component Location

Components Overview

This section describes the major components for the
LeeBoy 8510E Conveyor Paver. Become familiar with
these components before operating the machine.

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. The main control panel
slides to either side of the platform, featuring the PV480
digital display controller, work function switches, and a
vandalism cover for security and protection. Remote
screed control boxes are mounted on each side for
screed operator convenience.

Engine

The LeeBoy Model 8510E Conveyor Paver is equipped
with a Kubota V3800-TIE4F, 74 HP (55.2 kW) diesel
engine--a strong performer with the latest technology.
The engine is accessible through several access doors,
with a front service door where fuel lter components
are located for easier access.

Fuel-efcient and durable, this electronically-controlled
engine offers the latest in innovative emission solutions
that comply with stringent regulations for optimizing
combustion and reducing pollution. This Tier 4
Final engine complies 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.

Advanced emission-control devices and low-sulfur fuel
requirements--only Ultra-Low Sulfur Diesel (ULSD) can
be used in these engines--combine with after-treatment
methods such as Exhaust Gas Recirculation (EGR) and
Diesel Particulate Filters (DPF).

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 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, airow
from the engine-driven fan removes heat.

Refer to the Engine Operator’s Manual accompanying
your paver for additional engine information.

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 8510E Conveyor Paver now features
hydraulic test ports for ease and convenience in
checking pressure for its ve main functions.

Leeboy Model 8510E Conveyor Paver 3-3

Electrical System

The electrical system is powered by one 12-volt battery
mounted in the engine compartment. Each battery
produces 12 volts DC and maintains 1,000 cold cranking
amperes (CCA). An engine-mounted alternator with a
minimum of 60 amperes charging capacity keeps the
battery charged during normal operation.

Component Location

Hopper and Conveyors

The hopper wings are hydraulically raised and lowered
to open and close 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 efciently to produce a smooth asphalt
mat.

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.

The auger can also be controlled automatically when
the optional auger/conveyor sonic sensor system is
installed and active. 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.

Torque Hubs

The paver drive system contains two torque hubs that
provide power to propel the tracks.

The hopper’s conveyor bed can be lifted hydraulically,
allowing easy access to the paver undercarriage and
tracks for service and cleaning.

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 propane or the optional
electric heating elements mounted directly to the wear
plates. The electric vibrators mounted on the main
screed frame can be used to increase paving material
compaction.

Operation

Receiving the Machine

The LeeBoy Model 8510E Conveyor Paver is equipped
with hydrostatic-driven tracks that propel the paver
using friction-controlled joysticks. The amount
of steering is controlled by the amount of joystick
movement and the speed of the paver. Engine RPM is
set using the PV480 digital display unit on the operator
control panel. Always set throttle before starting to
pave.

Only authorized personnel who are
properly trained should operate the LeeBoy Model
8510E Conveyor Paver.

Although the machine has been checked thoroughly by
the manufacturer, road hazards or other factors during
transport may result in damage. Inspect machine for
any damage during transport. Contact your authorized
dealer immediately if any damage has occurred.

Initial and Daily Inspection

The following inspection is essential and should be
performed before the initial start-up. Visually inspect the
unit to check its general condition and for familiarization.
Continue with a check of the systems and components
shown in Table 4-1 below:

Hopper Cylinder Valve Lock

The hopper cylinder valve can be used to lock the
hopper wings when they are open or closed. (Figure

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.

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.

The engine is equipped with an
electric heat starting system. Using start additives,
such as ether, is not recommended as it could cause
an explosion resulting in severe injury and/or engine
damage.

4. Allow engine to warm up a few minutes before

moving paver for more efcient operation. In cold
weather let hydraulic oil warm to 60° (16°C) before
moving.

5. Set engine RPM using the throttle up and down

buttons on the PV480 digital display Engine Screen.
(Page 4-5) Set throttle at 2000 RPMs or higher.
This runs the engine hot enough for clean operation
and allows regeneration (see next section).

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.

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 efciency, use API-CJ4 (or

ACEA-E9 European equivalent) engine oil.

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.

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.

to any Status Icon and its color.

Table 4-3. Status Icons

Status Icon Description

Check Engine — When this lamp is illuminated, a fault exists within the control system. The engine
may continue to operate, however, it is unable to perform DPF cleaning either automatically or
manually.

Take action immediately to correct the fault.

Parking Break Switch — The park icon displays when the parking brake is applied.

NOTE: To perform a Parked REGEN, the “P” and “N” lamps must be illuminated.

Transmission Neutral — The neutral icon displays when the transmission is in neutral.

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.

Operation

Plus One Controller

The Plus One is a 50-pin controller operating in the
background that monitors paver control systems and
alerts the operator in the event of a fault. When the
Plus One controller senses a system fault, the Plus
One light on the control panel (Figure 4-30) illuminates
green and blinks continuously or blinks, then pauses,
then blinks again. A complete list of fault codes with
corrective action messages are shown in Section 5,

Troubleshooting.

Plus One Light

Figure 4-30. Plus One Light

When the key is turned on, the Plus One light will
illuminate for approximately three seconds while the
controller powers up, then turn off when the machine
is ready to start. The Plus One will not allow the engine
to start if any joystick is out of neutral or more than one
Run/Stop switch is in the RUN position.

Driving the Paver

The dual operator platforms allow easy and convenient
access for controls of most paver functions. The paver
is typically operated from the left side of the operator
platform, but it can also be operated from the right side
for your convenience. Multiple switches, levers and
dials allow the operators to control all paving functions.

NOTE: The Emergency Stop button on the main
operator console is used to shut down the engine
and all paver functions in the event of an emergency.

A steering and speed control box with dual joysticks
are located on each side of the platform. An optional
steering wheel control box is also available.

Ensure there are no people, obstacles
or other equipment in the path of the paver before
moving in either direction.

These faults will prevent machine movement:

• Steering control box not detected.

• Joystick(s) not in neutral at start-up.

• Pump control coil fault.

• Brake valve/pump neutral bypass coil fault.

• There is only one steering control box present.

• The fault happens in the steering control box that has

control (Run/Stop switch in the RUN position).

• The fault occurs when neither steering control box is
in control.

Figure 4-31. Operator Control Station

NEVER leave the operator station
unattended while the paver is in gear or in motion.
Operator must return joystick(s) to the neutral
position and turn the RUN/STOP switch to the STOP
position before leaving the operator platform.

NOTE: The engine will not start unless the E-STOP

button is disengaged, the Run/Stop switch
is in the RUN (center) position, and the
joysticks must be in the NEUTRAL (center)
position.

4-18 LeeBoy 8510E Conveyor Paver

Operation

Activate/Deactivate Operator Control Station

Only one operator control station can be activated at a
time for the paver to function. While the paver is typically
operated from the left side, the operator can change the
active station at any time using the following procedure:

1. Place both joysticks in the NEUTRAL (center)

position. (Figure 4-32)

2. Move the RUN/STOP switch to the STOP position
on the control box not being used to deactivate:

• The Run/Stop switch controls stopping the
machine and also activating/deactivating the
operator control station. When the switch is
set to the STOP position, that operator control
station is deactivated. When switch is set to
RUN, that operator control station is activated.

• BOTH joysticks must be in the NEUTRAL
position and BOTH Run/Stop switches in the
STOP position to change from one steering
control box to the other.

3. Activate the control box being used by setting the
Run/Stop switch to the RUN position.

4. Start the engine and allow the engine to warm a few
minutes.

If the joysticks are in the forward
position and the Run/Stop switch is in the STOP
position, the Plus One will disable the control box
after a set period of time. This is a safety measure
in the event the operator leaves the station with the
control box still active. The operator must move
joysticks to NEUTRAL (center) position, then toggle
the Run/Stop switch from RUN to STOP and back to
RUN again to regain control.

NOTE: Material from the opposite side cannot be

augered to the working side, however, the
operator can leave both Under Auger Cut-Offs
shut and open the end gates on the screed
for patching potholes and other small road
repairs.

Steering and Speed Control

Use the dual joysticks for steering and speed control. It
is important to move the joysticks SLOWLY. Lift up on
the joystick collar and move joystick either FORWARD
or REVERSE. The joystick collar will lock back into
place in the NEUTRAL position. The RUN/STOP switch
applies parking brake when set to the STOP position.

Be aware of the terrain and driving

conditions. Adjust speed accordingly.

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 joystick collar
and push joystick forward to reach the desired speed.

• To move in reverse, lift up on the joystick collar and
move joystick backwards to reach desired speed.

• Return joysticks to the neutral position to stop paver.

LeeBoy 8510E Conveyor Paver 4-19

Operation

• 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.

• 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 30
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.

NOTE: If equipped with the optional steering wheel

control box: If the joystick steering function
is not being used, the Run/Stop switch must
be in the OFF position.

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 8510E 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 sides of the Leeboy
8510E paver for your convenience. The wand is
conveniently located on each side of the operator’s
station. (Figure 4-33) The hose reel is located on the
side of the paver.

1. Extend hose from the reel.

2. Squeeze the wand handle and spray area. Release
the wand handle when nished.

3. Rewind hose back onto the reel.

Hose Reel

Stopping the Engine

1. Throttle back to idle using settings on the digital
display screen.

2. Turn ignition key on 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.

Figure 4-33. Spray Down Hose Reel

• Ensure the area is clear of others before spraying.

• Open the hopper wings and raise the screed.

• Allow the screed to cool at least 10 minutes before

spraying to prevent possible burns from solvent spray
on a hot screed. The screed should be warm, but not
hot.

4-20 LeeBoy 8510E Conveyor Paver

Operation

To operate the Spray Down system:

1. Turn the Spray Down switch on the control panel

ON. (Page 3-6)

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.

Never spray cleaning solvent or

release agent near the screed heating element or

near open ame. These agents are highly ammable

and can ignite, causing serious personal injury.

When using solvents and release
agents, consider the environment and DO NOT allow
cleaning solvent to run onto the ground. Only spray
down the machine in a designated area away from
the paving site.

Start at the front of the machine and work rearward,
using a scraper if necessary, paying particular attention
to ensuring built-up material is removed from:

• Push Rollers: Rotate the rollers while cleaning and

soak bearing ends to maintain free rotation.

• Hopper and Conveyors: Thoroughly clean surfaces

and any material accumulating in chains, drive
sprockets, idler shaft, bearings and tunnel areas.
AFTER cleaning the machine, operate the conveyors
briey to carry solvent into return areas where it can
help dissolve hidden asphalt material.

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 LeeBoy Model 8510E 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 4-23)

4

• Augers: Scrape away any accumulated material
around bearings and clean contact surfaces down to
the metal to avoid quick build-up while paving.

• Screed: Face and bottom plates should be clean and
smooth on the main and screed extensions to achieve
a smooth paving mat.

• Operator Platforms: Be sure to wash away solvent
residue so walk boards and operator platforms do not
remain slippery.

Propane Burner Ignition

IT IS IMPORTANT TO OPEN PROPANE VALVES IN
THE ORDER SHOWN BELOW. (Figure 4-34)

Figure 4-34. Propane Valve Order

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 4-34 and 4-36)

Electric Screed Heat (Option)

The LeeBoy 8510E Conveyor Paver offers an optional
Electric Heat system to heat the screed, including the
screed extensions, in lieu of the propane 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. (Figure

4-38)

A hydraulically-driven generator provides power to the
electric heat control box mounted in the center on the
rear side of the machine. The electric heat box is pre­wired for the heated endgates option. If not equipped
with this option, the left and right endgate switches do
not function.

NOTE: Adjust the pressure regulator valve IN or OUT

until the propane pressure regulator gauge
reads 15 pounds.

NOTE: It may be necessary to maintain low heat on

the screed if paving on a cool, windy day.
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 4-35)

2. When the ames extinguish, TURN OFF ALL burner
valves clockwise to the OFF position. (Figures

NOTE: Allow the screed (and screed extension) to

heat 15 minutes before beginning to pave.
Lower the screed two inches off the ground
while heating to prevent cold air and wind
from affecting the heating process.

To operate the electric screed heating system:

1. Start the paver and idle until the engine reaches
normal operating temperature.

2. Set the throttle on the PV480 display to PAVE (1800
RPMs). Do not exceed 1800 RPMs.

3. Raise the screed plate one or two inches off the
ground.

4. Turn the electric heat control box power ON by
ipping the power switch up. (Figure 4-38)

5. Press the Start Heat button.

6. The HEAT ON indicator light will illuminate and stay
on as long as the element is heating the screed.
(The factory-set heat cycle is 20 minutes, which
should generate enough heat to begin the paving
process. Operating in cold temperatures may affect
the screed plate temperature slightly.)

7. If the heat cycle has completed but the screed
plates still require heating, restart the cycle by
repeating Step 5.

Hopper Wings

The hopper wings are hydraulically opened so the
hopper can be lled with paving material. (Figure 4-39)
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

1. Push the hopper wings lever to OUT on the manifold

to fold out hopper wings. (Pages 3-6 and 3-7)

2. Be sure the hopper wings are completely extended

before receiving paving material from the truck.

3. Push the hopper wings lever 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.

4-24 LeeBoy 8510E Conveyor Paver

Operation

Conveyors

The LeeBoy Model 8510E Conveyor Paver is equipped
with two automatic conveyors that deliver asphalt evenly
to produce a smooth asphalt mat. (Figure 4-40)

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.

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 and 3-7)

• If the conveyors are running while the Under Auger
Material Cut-Offs are closed, there will be spillage,
which is normal. To help prevent this spillage, work
conveyors manually when loading hopper and not
paving.

Under Auger Material Cut-Offs

The Under Auger Material Cut-Offs are another
important function of the paver. The cut-offs are used
primarily to control the ow of asphalt to the screed
and hydraulic screed extensions. The cut-offs enable
varying paving widths as narrow as one inch (30.5 cm)
and as wide as 15 feet (4.6 m), depending upon the
screed option.

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-offs minimizes
clean-up at the end of pulls. (Figure 4-41)

• The right and left cut-off levers on the hydraulic

controls open and close the cut-off gates. (Pages

3-8 and 3-9)

• Holding the lever in the OPEN positions increases
asphalt ow to the screed. Holding the lever in the
CLOSED position decreases asphalt ow to the
screed.

4

• Irregular movement of the conveyor indicates that the

conveyor chains need adjustment.

• NOTE: Check conveyor chain adjustment every 100
hours. (Section 5, Pages 5-8)

Never leave the paver unattended

while the conveyor is operating. 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 efciency.

Operation

Electric Flight Screw

The electric ight screw is an added convenience to
the operator. (Figure 4-42) A screed height gauge
is located on both sides of the paver to provide the
operator with a quick reference to the location of the
electric screw.

Set the Screed, Flight Screw and Endgate

The main screed and screed extensions are heated
by heating elements and equipped with replaceable,
heavy-duty wear plates. Use the screed extensions
when paving widths exceeding eight (8) feet. (Figure
4-43) The screed extensions should be heated before
making any adjustments using the wrench provided.

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.

You can extend or retract the screed extension using
the extension levers on the hydraulic controls. (Pages

3-8 and 3-9)

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.

Operation

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)

NOTE: Never allow the endgate to carry the weight of

the screed to prevent uneven compaction.

4

3. To set the depth, you can place a small starter block
under the screed while you make adjustments.

(Figure 4-45)

Figure 4-45. Starter Blocks Location

4. Level the screed using the electric ight screw

(Figure 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.

NOTE: Both joysticks must be in the forward position

to operate the electric ight screw on the left

side, but will work at any time in the MANUAL
position.

• 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)

Figure 4-46. Endgate Tilt Screw Adjustment

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.

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 8510E Conveyor Paver 4-27

Operation

Sonic Auger

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 most often used when paving widths of
nine to 15 feet (2.7 - 4.6 meters) and are not used in the
manual mode.

The sonic auger sensor sits in the screed mount and
connects to the plug under the screed auger dial box.
(Figure 4-47) It detects the material height and controls
the auger height by automatically turning the auger on
and off.

NOTE: The augers are not needed when paving under

eight-feet wide (2.4 m).To operate the sonic

auger sensor:

To operate the sonic auger sensor:

1. Plug in the sonic auger sensor unit (bottom of the
Material Height Dial).

2. Pull the auger lever down.

3. Set the left and right auger switches on the left side
of the control panel to AUTO.

4. Adjust material height at the endgate using the
auger dial beside the steering control box (or
remote screed 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 will automatically turn off. It will
turn back on when the material level drops.

Operation

Starting to Pave

The LeeBoy 8510E Conveyor Paver provides superior
paving for driveways, small to large parking lots,
and secondary roads. It has a production rate of
approximately 250 tons per hour.

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.

• 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.

• It is very important that the rst pass be straight as it
will serve as your guideline for the following passes.

NOTE: If paver is equipped with the optional truck

hitch, the truck driver won’t need to maintain
brake pressure.

• Adjust truck push rollers to the appropriate height
needed for asphalt truck. (Figure 4-49) Use truck
hitch controls if equipped with this option. (Page

4-35)

• There are ve (5) set heights on the truck push
rollers.

• Remove bolts on both sides of each push roller,
align with either of the ve slots on the frame at
desired height, and reinstall bolts.

• Both push rollers should be at the same height
to prevent damage.

• Extend the lower guide bar gauge to further assist you
in paving a straight line from the operator’s station.

(Page 4-50)

• 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.

• Use a reference guide such as a curb, gutter, adjacent
mat or string line.

Operation

Basic Paving

1. Follow the start-up procedure. (Page 4-4)

2. Position paver at the starting point for the mat.

3. Adjust screed as needed. (Page 4-26)

4. Open the Under Auger Material Cut-Off. (Page

4-25)

5. Open hopper wings. (Page 4-24)

NOTE: Allow only a partial load of asphalt to enter

the hopper when rst starting to pave.

6. Turn the left and right conveyor sonic paddle
switches to the AUTO position.

NOTE: When in the AUTO mode, the conveyors will

operate at the selected speed but will turn on
and off when using the sonic auger.

7. Turn the left and right auger switches AUTO,
using the dials to control the material height at the
endgate.

8. When the material starts moving into the sonic
range, the auger speed will slow proportionately
and turn off, then turn back on when the material
level drops.

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 (on the
right side of paver) and the center plate before
adjusting crown and valley mechanism. (Figure

4-51)

NOTE: The locking bolt on the optional 815HD screed

is located beside the crown adjustment
mechanism. (Figure 4-51)

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.

9. When the material begins to discharge from under
the screed, set the screed lift lever to the FLOAT
position.

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 switches to the OFF position
and set both cut-off levers 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.

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.

Operation

Mat Texture Adjustment

The screed extension can be adjusted for a smoother or

1

coarser mat texture by using the Angle of Attack (AOA)
adjustment screw. (Figure 4-54)

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.
You can adjust the mat texture using the AOA

2

adjustment screw in the center. To make the AOA
adjustment:

Figure 4-52. Crown Adjustment

1 - Adjuster

2 - Crown Handle

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. (Figure 4-53)

• Negative crown is the lower in the center of the
screed plate, often used in an alley where drainage is
necessary. (Figure 4-53)

1. Spray down the screed.

2. Turn on the screed heat.

3. Turn the screw 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.

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.

Operation

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.

ALWAYS back the paver up loading

ramp with the screed end rst. ALWAYS be alert to

uneven surfaces and the potential reactions when
transferring the paver from surface to surface.
Serious injury or even death can result.

Use extra caution steering when
loading and unloading the paver as slight steering
changes on ramps and trailers can cause the
machine to fall off the ramp or transport trailer.
Serious injury or even death can result.

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 sufcient
ow to operate all functions properly.

4. Set steering control lever so paver moves very
slowly.

5. BEFORE moving the machine, ensure:

• The main screed position is UP, the screed
extensions are retracted and locked, and the
hopper wings are locked.

• Auger extensions are removed.

• The Under Auger Material Cut-Offs are

CLOSED.

6. Move paver forward down the ramp as shown on

Figure 4-55.

Never move the paver in reverse while

the cut-off gates are open.

Figure 4-55. Correct Loading and Unloading

Position

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.

Loading

To prevent damage to the
undercarriage and throughout the paver, reduce
traveling speed before the paver tracks come into
contact with loading ramps or any abrupt change
in the surface. The track drive sprocket or other
components can be damaged by excessive shock.

The paver must be loaded screed-end

rst to prevent damage.

1. Move paver to base of ramp. Line up tracks with the

ramp.

2. BEFORE moving the machine, ensure:

• The main screed position is UP, the screed
extensions are retracted and locked, and the
hopper wings are locked.

• Auger extensions are removed.

Operation

• The Under Auger Material Cut-Offs are
CLOSED.

3. Load the paver screed-end rst. Set throttle at half
the operating RPMs.

4. Set steering control lever so paver moves very
slowly onto the ramp.

5. Using the steering control joysticks, SLOWLY guide
paver up the ramp.

6. Position paver in center of trailer.

7. Lower the screed.

8. Shut down the engine.

9. Secure paver to transport using the following tie­down procedures.

Tie-Down Procedure

1. Position paver in center of the trailer.

2. Attach tie-down chains to the front weight block
and the D-Rings in front of the torque hubs. (Figure
4-56).

Towing

Ensure the paver is on level ground
and blocked to prevent machine from moving while
preparing for towing. Be especially careful after
disconnecting the torque hub as the paver could roll.

While it is strongly recommended that the paver be
transported rather than towed, there are situations
where you may need to tow the paver off the road until
a transport vehicle arrives. Do not tow paver long
distances.

You must disconnect the torque hub to prepare the
machine for towing as follows:

1. Using a wrench, loosen one of the two bolts on the

torque hub cap, then remove the other bolt and
retain for next step. (Figure 4-57)

Topcon® Sonic and Dual Grade Control

Topcon® sonic grade
control, dual grade control

and slope options offer

paving professionals

screed control for

improving smoothness
along with assuring

accurate slope and

material thickness. These
controllers send signals
to the screed to precisely
maintain mat thickness
and slope as you pave.

Figure 4-64. Sonic Grade

Control

Sonic trackers continuously measure the elevation over
the surface, automatically averaging and adjusting the
tow point cylinder on the paver. The LCD digital display
is easy to see regardless of light conditions.

Choose from one of three options: Sonic Grade Control
(one side); Dual Grade Control or Dual Grade Control
and Slope (both Topcon P-32 systems). The dual
grade controls automatically maintain a set depth on
both ends of the screed. The Dual Grade and Slope
controls maintain a set depth on one end of the screed
and as et slope to the other end.

Start with a set point temperature of 200° - 250° F
(93.3° - 121° C). The screed runs warmer than the set
point temperature due to heat soak, which is normal, so
it’s better to start with cooler a temperature set point.
The displayed temperature (in red) must fall 25 degrees
below the set point before the heating elements turn on
again.

Maintenance

Maintenance Adjustments

Certain components of the paver need adjustments
for optimum performance, operation and general
maintenance.

Entanglement hazard! DO NOT run
the engine while checking and servicing conveyor
components. NEVER perform any adjustments while
the engine is running.

Conveyor Flight Chain

The conveyor ight chains must be adjusted every 100
hours. If irregular movement of the conveyor occurs, an
adjustment is needed regardless of the time interval.

6. After the conveyor chain tension is set, retighten
locknuts and bolts holding the ight chain assembly.

NOTE: If the adjustment bolt has reached its

maximum adjustment level, remove two links
in the conveyor chain and add a half link. This
repair should bring the adjustment bolts back
to full travel.

Keep conveyor ight chain properly

oiled with cleaning solvent or release agent during
cold weather to keep conveyors functioning
smoothly.

Conveyor Drive Chain

Keep chains clean, lubricated and properly adjusted.
Inspect both drive chains at the rear track. If the chains
are loose, adjustment is necessary.

1. Shut off paver.

2. Open engine access door on the side adjusting to
locate the conveyor drive chain bolts. (Figure 5-7)

3. Loosen the jam nuts on the chain adjuster.

2 - Locking Nut

3 - Hold-Down Nut

There are four (4) adjustment bolts, two (2) for each
conveyor. Use the following procedure to make this
adjustment on both sides of the conveyor:

1. Raise conveyor bed and insert safety prop. (Page

5-4)

2. Loosen the hold-down nuts (one on each side of

each adjustment bolt). (Figure 5-6)

3. Loosen each locking nut beside the adjustment bolt.

4. Turn each adjustment bolt alternately the same
amount. For example, turn one bolt one half turn,
then the other bolt one half turn, etc.

5. Continue alternating tightening to adjust to one (1)
inch deection: 1/2-inch up and 1/2” down between
the front roller and rst idler. (The pressure on the
chain will be noticeable as the bolts are tightened.)

4. Turn the chain adjuster to loosen or tighten the
chain, leaving approximately 1/4-inch of slack. DO
NOT overtighten.

5. Retighten jam nuts.

6. Repeat steps on the opposite conveyor drive chain.

Auger Drive Chain Adjustment

The auger chains should be snug, not loose. If the
chains need to be tightened, follow this procedure:

1. Loosen the motor bolts on the right and left auger

chains. (Figure 5-8)

2. Loosen jam nuts and turn the tension adjusters
counterclockwise to tighten chains.

3. Once adjusted, retighten motor bolts and jam nuts.

Screed Extension Top Guide Adjustment

1. Retract both screed extensions completely using
the left and right extensions switches on the control
panel. (Pages 3-6 to 3-7)

2. Raise the screed approximately two (2) inches and
insert a block to support the screed. Turn off the
engine.

3. Loosen the top slide rail lock-down bolts. (Figure

5-9)

4. Tighten the top rail adjusting setscrews until all are
snug, starting from the outside and working toward
the center on each side of the slide rail.

5. Retighten the top slide rail lock-down bolts.

6. Loosen the top slide rail lock-down bolts and insert
a .008-inch feeler gauge between setscrew and top
slide rail. Adjust to obtain the .008 gap between all
setscrews and top rail.

7. Loosen all top slide rail lock-down bolts, allowing
the slide rail to contact all setscrews. Retighten all
lock-down bolts and torque to 90 ft lbs.

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 switch to the LOW position if adjusting
low gear. (The blue 2-Speed light should not
illuminate.)

• Set the 2-Speed switch to the HIGH position if
adjusting high gear. (The blue 2-Speed light will
illuminate.)

Conveyor Switch Adjustment

Small adjustments may be necessary to conveyor
switch for optimum conveyor performance. (Figure
5-10) There are two positions of the conveyor ap:
One upper, shutting the conveyor OFF; and one lower,
turning the conveyor ON.

• When correctly adjusted, the conveyor shuts off when
the paddle is approximately eight (8) inches (20.3 cm)
from the top of the conveyor switch to the bottom of
conveyor paddle; and turns on when the paddle drops
to approximately 12 inches (30.5 cm).

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.
