MACHINE PRECAUTIONS
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
sufcient to penetrate the skin, which could cause
serious personal injury. Ensure all pressure is
relieved before disconnecting line, hoses or valves.
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.
• Use jumper cables ONLY as directed on Page
5-?. Improper use can result in battery explosion or
unexpected paver motion.
• 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.

Determining Proper Torque
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 2-6. Torque Wrench - Crowfoot
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)
Figure 2-7. 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
• Torque setting if the crowfoot is placed at 90° with
respect to the wrench
TS = TD * L / LH
OR
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
Mark Line on Nut
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
(Figure 2-12).
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
Figure 2-5:

difference
Figure 2-8. 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.
(Figure 2-12) The nut and backup hex can
then be marked to indicate if the coupling
loosens over time.

This section describes the major components for the
LeeBoy 8616B Conveyor Paver. Become familiar with
these components before operating the machine.
Engine
The LeeBoy Model 8616B Conveyor Paver is equipped
with a Kubota, 99 hp (74 kW) diesel engine, which is
mounted near the center of the paver and accessible
through several access doors on the engine cover.
A fuel lift pump mounted to the right side of the engine
draws diesel fuel from the fuel tank, which is also
mounted on the right side of the engine compartment.
The air cleaner is mounted at the back of the hood,
which 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.
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.
Hopper
The hopper wings are hydraulically controlled to raise
and lower the hopper. When fully open, the hopper can
hold a payload up to nine 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.
Augers
Right and left augers rotate counterclockwise 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 monoitor 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 lowdeck or by standing on the screed
walkboard.

Screed
Hydraulic System
The hydraulic system includes four hydraulic pumps
driven by the engine: 1) Left Drive Pump; 2) Right Drive
Pump; 3) Load Sense Pump and; 4) Charge Pump.
Torque Hubs
The paver drive system contains two torque hubs that
provide power to propel the tracks.
LeeBoy 8616B Conveyor Paver3-3
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 electric heating
elements mounted directly to the wear plates.
The hydraulically-driven vibrators mounted on the main
screed frame can be used to increase paving material
compaction.
Page 44
Component Location
Electrical System
The electrical system is powered by one 12-volt
battery mounted in the engine compartment next to
the generator. Each battery produces 12 volts DC
and maintains 1,260 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.
Electrically-heated pavers come equipped with a
generator mounted on the left side of the paver (inside
door under the hydraulic manifolds). The generator is
hydraulically-driven by a load-sense pump on the engine
pump stack. When the paver is at a preset engine
speed of 1600 RPMs and the hydraulic system is at
normal operating temperature, the generator operates
at a sufcient speed to produce 220 - 240 VAC.
All LeeBoy generators are equipped with an integrated
speed-control manifold. This manifold should not
require adjustment, but if there is a need to “ne tune”
the generator speed, there is an adjustment on the
manifold.
Once the heat cycle is started, a pre-programmed timer
controls the amount of time for output power from the
generator to go through the element connection supply
plugs coming out of the bottom of the Heating Control
Box to the heating elements.
Any element lead can be plugged into any supply plug
under the heating control/distribution box. All plugs are
equally rated.
Each element is sized to t properly in your screed, and
provide sufcient power to heat your screed plate to a
temperature that mix will not drag or stick to the lower
surface of the screed plate.
To know that the element is correct, you should read a
resistance between 25 ohms and 35 ohms.
Generator speed tuning should only
be done by an authorized LeeBoy dealer.
Heating controls provide the necessary connection
and control of the output power from the generator
to the heating elements. It is important to maintain all
components of the heating controls system in good
working order for safe and efcient screed heating.
The heating control is mounted near the middle of the
screed and is easily accessible to the screed operator
when a heating cycle is required.
There is a ve-second delay after the heat cycle is
initiated before the actual electric load is sent to the
heating elements to allow the generator to reach optimal
operating speed before the electrical load is required.

previously set speed.
NOTE: Only one operator control station can be active at a time.
The LeeBoy Model 8616B Conveyor Paver is equipped
with hydrostatic-driven tracks that propel the paver
using friction-controlled joysticks. The two joysticks
control the speed and direction of the paver in
conjunction with the machine speed setting. Ramping
for acceleration and deceleration are proportional to the
movement of the joysticks. (Page 3-5)
The propel system utilizes a dual path proportional
system to control the tracks. In low speed, the inside
track counter-rotates.
Steering the tracks is controlled by a hydraulic
proportional pump. 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.
Engine RPM is set manually by using the throttle up
and throttle down buttons located on the DP700 digital
display unit on the operator control panel. Always set
throttle before starting to pave.
The engine RPM automatically increases to 1800 RPM
when the conveyor or augers are engaged.
If the joysticks are set to the neutral position for 10
seconds, the engine will idle. When the joysticks are
taken out of neutral, the engine immediately returns to
the last set RPM.
Only authorized personnel who are
properly trained should operate the LeeBoy Model
8616B Conveyor Paver.

Operation
DPF Regeneration (REGEN)
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 bewteen 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.
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 level icon is shown on the engine screen.
(Figure 4-8) 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.
NOTE: See Section 5 Troubleshooting Chart on Page
5-33 for a complete list of fault codes.
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 and a green screen will appear
notifying operator the process is complete. Press the
“X” button to clear this screen.
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. Therefore, it
is important to allow the regeneration process to nish.
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.
Level
Figure 4-6. DPF Level Icon in Engine Screen
At Level 3, a screen will appear notifying the operator
that a manual regeneration is required. (Figure 4-9)
DPF
There are several factors that affect how often your DPF
regenerates and the life expectancy of your DPF lter:
• Grade of engine oil.
• Grade of diesel fuel.
• Use of additives.
• Mileage.
• Wear of other components.
DO NOT attempt to operate the unit,
change engine RPM or move from Park/Neutral
during the regeneration process.

Operation
DRIVING THE PAVER
The operator can operate the paver from either side of
the operator platform. Multiple switches and dials allow
the operators to control all paving functions. (Page 3-6)
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.
Operator Control Station
The paver is typically operated from the left side
of the operator platform, but the paver can also be
operated from the right side for your convenience. A
steering and speed control box with dual joysticks are
located on each side of the platform. The main control
panel console is located in the center. (Figure 4-8)
1
2
The paver can only operate using one station at a time.
The operator must activate the side being used and
deactivate the other using the following procedure:
• Place both joysticks in the neutral position on the
side being deactivated. (Figure 4-9)
• Move the RUN/STOP switch to the STOP position.
• Operator can then move to the other operator
station to activate that side by simply ipping the
RUN/STOP switch to the RUN 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.

Steering and Speed Control
After activating the desired control station, you are ready
to drive the paver using 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 4-9)
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.
LeeBoy 8616B Conveyor Paver4-10

Operation
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.
• 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: Ground speed percentages can be changed
on the Paver Screen using the Up and
Down arrows. The maximum travel speed
is determined by the set ground speed
percentage.
PAVER OPERATION
Spray Down
Always spray down the LeeBoy Model 8616B 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 8616B paver for your convenience. The wand
is conveniently located on each side of the operator’s
station. (Figure 4-10) The hose reel is located inside
the panel.
1. Extend hose from the reel.
2. Navigate to the paver screen on the DP700 digital
display to activate spray down system. (Page 4-5)
3. Squeeze the wand handle and spray area. Release
the wand handle when nished.
4. Press the Paver screen Spray Down again to turn
the spray down system off and rewind the hose onto

Operation
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, consider the environment
and DO NOT allow cleaning solvent to run onto the
ground.
Screed Electric Heat Control
The LeeBoy 8616B Conveyor Paver features a
hydraulically-driven generator that powers the electric
heat control box mounted in the center of the screed for
easy access. This control box is where you will select
the heating function before you begin to pave. (Figure
4-11).
NOTE: Engine speed automatically increases to
1,600 RPMs when the heat cycle is active.
To operate the screed heating system:
1. Start the paver and idle until the engine reaches
normal operating temperature.
2. Raise the screed plate one or two inches off the
ground.
NOTE: The engine speed automatically decreases to
idle after the heat cycle completes.
6. If the heat cycle has completed but the screed
plates still require heating, restart the cycle by
repeating Step 4.
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.
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.
Set the Screed and Endgates
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 a small starter block
under the screed while you make adjustments.

lower the endgate until it is about 1/4-inch (6.35 mm)
below the screed. (Figure 4-14)
Operation
NOTE: Never allow the endgate to carry the weight
of the screed to prevent uneven compaction.
Figure 4-14. Endgate Depth Screw Adjustment
7. 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 4-15)
4
Figure 4-15. Endgate Tilt Screw Adjustment
8. If the endgate digs into the asphalt at the front,
adjust the tilt screw until the endgate tilts back more.
9. When making a joint, the endgate must be set to
where it ts ush with bottom of screed.
10. On the rst pass, leave approximately six to eight
inches (15 - 20 cm) of unrolled asphalt where the
joint will be made.
11. 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.
12. 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.
13. If making a cold joint, set the endgate down about
1/4 inch (6.35 mm) for a nice, even edge.

Operation
Hopper Wings
The hopper wings are hydraulically opened so the
hopper can be lled with paving material. (Figure 4-16)
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.
(Page 3-6)
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.
Conveyor
The conveyor is a very important part of the paver. Pay
close attention to integrating its operation into the total
operation of the paver. (Figure 4-16)
NOTE: Operating the conveyors in manual mode
with the augers in automatic mode is the
preferred method for paving with the LeeBoy
Model 8616B Conveyor 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.
• 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.
• Irregular movement of the conveyor indicates that
the conveyor chains need adjustment. (Figure
4-17)
NOTE: Check conveyor chain adjustment every 100
hours. (Pages 5-7 to 5-8)

Cut-offs can be used to limit material ow when making
narrow passes at the beginning and ending of each
pass or pull.
NEVER backup with the cut-off gates
open. The cut-off gates are designed to break away
from cylinders when hitting a manhole or other
object when forward, but not in reverse.
• The right and left cut-off switches on the operator
control panel 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.
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. (Figure 4-19)
A sonic auger sensor connects from the paver to the
screed. It detects the pile height and controls the
conveyor and auger speed by regulating the hydraulic
pump output.
4
Figure 4-19. Sonic Auger Sensor
• The right and left auger dials on the screed control
box (Page 3-8) controls pile height. Turning
the dials clockwise increases pile height while
counterclockwise decreases pile height.
• When the pile 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.
• The sonic auger sensors are not used in the
manual mode.
NOTE: Auger speed is adjusted only in the
manual mode. Conveyors can be adjusted
separately in both manual or auto modes.

Operation
Tow Point Cylinders
The tow point cylinders are an added convenience to
the operator for adjusting the depth of the screed. This
feature makes it possible to lay down an asphalt mat of
uniformly desired thickness.
A tow point cylinder gauge is located on both sides of
the LeeBoy Model 8616B Conveyor Paver. (Figure
4-20)
STARTING TO PAVE
The LeeBoy 8616B 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.
• Always pave in low range.
Figure 4-20. Tow Point Cylinder
1. Before paving, center the tow point by referring
to the screed elevation gauge on each side of the
paver. Raise or lower until the rod end is ush with
the “0” on the indicator.
2. While paving, refer to both gauges and make minor
adjustments to the screed using the tow point
adjustment or ight screw.
NOTE: Tow point cylinders will not function manually
when the machine is in the AUTO mode.
• 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.
• It is very important that the rst pass be straight as it
will serve as your guideline for the following passes.
• Extend the upper and lower guide bar gauges to
further assist you in paving a straight line from the
operator’s station. (Figures 4-21 and 4-22)

Components operate in both automatic and manual
mode.
The paver can operate using one side only. Material
from the opposite side cannot be augered to the
working side. It is possible to leave both cut-off gates
shut and open the endgates on the screed for paving
potholes and patching.
Operation
7. Turn the left and right auger switches AUTO, using
the dials to control the pile height at the endgate.
(Page 3-6)
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.
NOTE: The pile height must be set to the highest
point when the endgates are closed. When
the endgates are open, the pile 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 switch to the FLOAT
position. (Page 3-6)
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 sonic paddle 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.

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 4-12)
4. Open cut-off gates under auger. (Page 4-15)
5. Open hopper wings. (Page 4-14)
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 PADDLE position and set speed
using the right and left conveyor dials. The conveyor
speed can be adjusted while paving if needed.
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. (Page
4-15)
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.

Operation
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 mechanism on the screed. (Figure
4-23)
Figure 4-23. Lock Down Bolts
2. Use the gauge located at the center of the screed
above the standing platform.
3. Set the pointer rod for the crown to “0.”
4. Place the lever at the desired number for the proper
crown. (The setting is based on a 10-foot mat.)
NOTE: Always check that proper crown is achieved
by using a string or straight edge to measure
the distance between a at, level surface to
the center bottom portion of the screed.
Figure 4-24. Crown Control Lever
5. Make adjustments using the crown control lever.
(Figure 4-24)
NOTE: The maximum crown is two inches.
NOTE: The leading edge crown is set at 0 when
shipped from the factory. The chain
connecting the leading and trailing edge
crown control assures that the relationship
of the edges remains constant as the trailing
edge is changed to meet job conditions.
• 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.
LeeBoy 8616B Conveyor Paver4-18
Page 70
Figure 4-25. 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.
Operation
Mat Texture Adjustment
The screed can be adjusted for a smoother or
coarser mat texture by using the Angle of Attack (AOA)
adjustment screw. (Figure 4-26)
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
adjustment screw in the center. (Figure 4-26)
To make the AOA adjustment:
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.

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 4-27.
Never move the paver in reverse while
the cut-off gates are open.
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 screed position is UP.
• Auger extensions are removed.
• The extendible screed is IN.
• The cut-off gates below the augers 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.

transporting the paver.
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.
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.
3. Shut off engine.

Track Tension
The hydraulic adjustment cylinders are automatic and
provide even tension on the tracks to prevent excessive
wear to the paver’s undercarraige.
This feature requires the operator to maintain at least
a three-quarter throttle setting when backing with a
loaded hopper to maintain the proper track adjustment.
Failure to maintain adequate throttle
setting can result in poor performance or damage to
the machine.
Track tension is controlled by a load-sense pump that
operates all cylinders. The track tension is set on the
main manifold located at the hopper end of the electrical
valve manifold.
Pressure Check
The track hydraulic pressure is set at 1200 PSI at the
track tension main manifold.
Too much track tension pressure
will cause premature wear on the chains, idler and
sprockets.
3. If adjustment is needed, locate the pressure-
reducing valve on left side of main manifold. (Figure
5-8)
4. Remove valve cap with an allen wrench.
5. Adjust the pressure-reducing valve clockwise for
more tension or counterclockwise for less tension.
Track Pressure Relief
Relieving track tension pressure is set to 2300 PSI. The
pressure-relief valve is located on opposite side of the
main manifold. (Figure 5-9)
Pressur

High Gear Adjustment
This adjustment should only be
performed by an authorized LeeBoy dealer. Work
not performed by an authorized dealer can damage
machine and void the warranty.
Your authorized LeeBoy dealer will perform the tracking
adjustment on the high side gear by adjusting the
screw on the underside 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
procedures:
1. With paver running, push the 2-Speed switch to the
ON position, activating high gear.
2. Adjust screw on bottom of hydraulic motor until you
feel back pressure on the adjustment screw. This
indicates adjustment is close.
3. Finalize adjustment by making a one-quarter
(1/4) turn at a time until the correct adjustment is
accomplished.
NOTE: If hydraulic motor has not been previously set,
ten revolutions of the adjustment screw may be
required before noticing any difference in travel.
ELECTRICAL SYSTEM
The electrical system is a 12-volt negative ground
system. Connect the positive (+) cable to the positive
(+) post of the battery. Connect the ground cable to
the negative (-) post of the battery. It is advisable to
disconnect the negative (-) cable rst and connect it last.
Reversed polarity can damage the electrical system.
Fire and Explosion Hazard! Always
observe battery polarity when connecting a battery
charger or jumper cables to the battery: negative (-)
to negative (-), positive (+) to positive (+). Failure to
do so can produce sparks.
When connecting a booster battery, connect one end
of the rst jumper cable to the positive (+) terminal of
the dead battery and the other end to the positive (+)
terminal of the booster battery. Connect one end of the
second jumper cable to the negative (-) terminal of the
booster battery and the other end to the frame of the
paver with the dead battery.
Fire and Explosion Hazard! Be sure
that the battery charger is in the OFF position before
connecting it to the battery.
Be sure to keep the battery fully charged during cold
weather to keep it from freezing. Freezing weather has
little effect on a fully-charged battery.

Battery Servicing
Batteries contain sulfuric acid.
ALWAYS wear safety goggles and protective clothing
when servicing the battery.
NEVER allow battery uid to come into
contact with clothing, skin or eyes. If battery uid
contacts the eyes or skin, immediately ush with
clean water and obtain prompt medical treatment.
Keep sparks and ames away from the
batteries as electrolyte gas is highly ammable.
1. Open cover on left side of the paver to access
battery.
NOTE: When replacing the battery, discard the old
battery properly.
2. Before connecting the batteries, turn off the master
switch, located under the operator control panel.
(Figure 5-11)
ALWAYS turn the master battery
switch off when working on the electrical system
or welding anywhere on the machine. Damage to
electrical components could result.
ALWAYS turn the battery disconnect
switch to the OFF position when nished operating
the paver. This will eliminate the possibility of a
battery or cable short that could cause a re.
Alternator
The alternator supplies electrical power to electronic
controls and charges the battery. Its built-in regulator
controls voltage output. (Figure 5-12)

3. Be certain that battery terminals and posts are clean
and that the battery cable terminals are tight.
Dirty or loose battery connections can
create high electrical resistance and permit arcing.
4. If corrosion is present around terminal connections,
remove and wash with ammonia or a solution of
1/4-pound (0.11 kg) baking soda added to one quart
of warm water. Ensure the vent caps are tight to
prevent solution from entering the cells.
5. Pour clean water over the battery and surrounding
area to rinse away the solution.
6. Check vent cap breather openings to ensure they
are clear.
Figure 5-12. Alternator
Use the following precautions to prevent damage to the
alternator or regulator:
• Never polarize the alternator.
• Never ground any alternator terminals or circuits.
• Always disconnect the battery before disconnecting
or connecting the alternator.
• Never disconnect the alternator while machine is
operating.
• Ensure wiring is properly connected before
connecting the battery.
• Always connect a booster battery in the proper
polarity: negative (-) to negative (-) and positive (+) to
positive (+).

Generator Voltage Testing
The generator is hydraulically-driven. When the paver
engine is at 1600 RPMs and the hydraulic system is at
normal operating temperature, the generator should
produce between 220 VAC and 240 VAC.
The generator voltage depends upon speed (RPMs),
increasing voltage as RPMs increase and decreasing
voltage as RPMs decrease. The voltage will decrease
signicantly if the generator speed is slower than 3480
RPMs.
NOTE: When testing the generator voltage ensure the
paver engine is at 1600 rpm and the hydraulic
temperature is at normal operating levels.
To test the generator voltage:
1. Use volt meter to measure between the two main
input wires L-1 (black wire) and L-2 (white wire).
(Figure 5-13)
2. If you measure from L-1 to the frame of the paver, or
ground, the voltage will be half the rated output of
the generator. The voltage should be the same as
measured at the control box.
Generator Speed Tuning
This adjustment should only be
performed by an authorized LeeBoy dealer. Work
not performed by an authorized dealer can damage
machine and void the warranty.
A voltmeter set to read frequency (Hz) can be used to
test generator speed. When the engine is running at
1600 RPMs, the generator should operate at 58 to 62
Hz, or a speed of 3480 to 3720 RPMs. If the generator
speed drops below 3480 RPMs, the voltage output
and performance of the heating system will decrease
signicantly.
The generator should never be
operated at a speed of 3800 RPMs or greater.
Generator damage will occur and void your warranty.
Your authorized LeeBoy dealer will perform the
following procedure:
1. Remove back panel from generator housing to
access the rear of the generator.
2. Set voltmeter to read frequency (Hz), to measure
between the two main input wires L1 and L2. (Figure 5-12) A photo tachometer may also be used to
check the speed of the generator at the motor
coupling by removing the motor coupling shield.
Figure 5-13. Generator
If the voltage is lower, make certain the generator is
turning the correct speed by testing with a Hz meter or
photo tachometer.
NOTE: When testing the generator speed, make
certain that the paver engine is at 1600 rpm
and the hydraulic temperature is at normal
operating levels.
3. Note that 60 Hz is exactly 3600 RPMs. For every
Hz above 60, an increase of 60 RPMs can be added
to 3600 RPMs. For every Hz below 60, a decrease
of 60 RPMs can be subtracted from 3600 RPMs.
Example: 60 Hz is 3600 RPMs. A reading of 62 Hz
would be 3720 RPMs. A reading of 58 Hz would be
3480 RPMs.
Always replace shields and panels
when nished testing.

Flow Control Adjuster
Generator Capacitor
Replacement
There are no other voltage adjustments that can be
made to the generator.
The capacitor controls and regulates voltage while the
machine operates. If the capacitor fails, the voltage will
drop below or no output at all. (Figure 5-13)
If experiencing a drop in voltage, replacing the capacitor
will help determine if the capacitor is at fault.
To perform this procedure:
Figure 5-14. Generator Flow Control Adjuster
Adjusting the ow-control adjuster on the front of the
manifold controls speed of the generator. (Figure 5-14)
NOTE: The integrated ow-control manifold is pre-
set and will maintain the generator at it’s
proper speed if the correct amount of oil is
supplied to the set. If the temperature of the
hydraulic system rises above 160°F, some
slippage may occur through the gear set of
the generator motor, and the generator may
slow slightly.
Improper adjusting will overspeed and
cause damage to the generator.
To perform this adjustment:
• Locate the Flow Control Adjuster and turn to increase
or decrease the speed as needed.
• Turning clockwise will decrease the generator speed.
Turning counterclockwise will increase the generator
speed.
If the generator will not operate at the correct speed,
test the hydraulic ow from the pump or check the
generator motor for excessive case drain ow. The
case drain should not leak more than one gallon per
minute. Replace the generator motor or paver pump if
either are operating incorrectly.
1. Shut down the machine.
2. Detach the wires on top of the capacitor.
3. Remove the capacitor and replace with new one.
4. Reattach wires.
Screed Electric Heat Elements
The electric heat control box contains the element
breakers and main outputs for the screed heating
system. Powered by 220VAC and 240VAC, each
element has two breakers. (Figure 5-15)
The control box consists of three major types of
components:
• The system timer is located in the upper left hand
corner of the box.
• The element relays are located in the upper right hand
corner of the box.
• The element breakers are located in the lower surface
of the box.
The other block in the center is used as a wire junction
block only. Refer to the wiring schematic at the end
of this manual, and you will note how the following
connections are made.
NOTE: Control boxes are manufactured to t all
screed and paver combinations. If not all
plugs are connected to wires, it may be
normal. Be sure to keep open plugs with the
plug terminator(s).
LeeBoy 8616B Conveyor Paver5-14
Page 88
When the HEAT ON button is depressed, 12VDC is

momentarily applied to this terminal to start the timer
cycle. During the timer cycle, power will not be applied
to this terminal unless the HEAT ON button is depressed
again.

2 - L-1 Circuit Breakers
3 - Power On Toggle
4 - Heat On Button
5 - Wire Junction Block
6 - L-2 Circuit Breaker
Any element lead can be plugged into any supply plug
under the heating control/distribution box. All six plugs
are equally rated.
• Each element output consists of two wires--one
connects to the L-1 circuit and the other to the L-2
circuit.
• Each breaker has two terminals--one is connected
to the main input and the other terminal to an element
output wire.
• The L-1 circuit is the left bank of element breakers.
• The L-2 circuit is the right bank of element breakers
and wired slightly different. Each leg goes from the
main L-2 power lead through a breaker, then through
one of the six contacts on the element relays.
It is these relays that “make” or “break” the circuit to
each element to start or stop the heating cycles.
There are six terminals on the timer:
• The top two left terminals are the main 12VDC input
terminals.
• The ground is on the left.
• The power is on the right.
• The top right terminal is the common terminal to the
internal timer relay that controls the heat system.
When power is applied to the input terminal, it is also
jumped to the common (or COM) terminal on the timer.
• The lower right two terminals on the timer are the
outputs of the internal timer relay.
Element Relays
There are three relays in the control box. Each relay has
two separate sets of contacts operated by one coil.
One set of contacts are the two terminals at the top left
of the relay, and the other set is at the bottom left. When
the coil is energized, both sets of contacts will close.
The element relays are 12-volt, DC-controlled with dual
contacts rated for 240VAC.
To test the relays, perform the following procedure:
1. Disconnect any wires to the relay, or completely
remove it from the control box. (Figure 5-15).
2. Place the leads of an ohm meter or continuity tester
across the contact terminals (2 - 4) or (6 - 8).
NOTE: Without 12VDC applied to the coil of the
relay, the contact terminals should have
no continuity through them (open). If you
do not have 12VDC applied to the coil and
the contacts are closed, your contacts are
incorrect and the relay should be replaced.
3. With the ohm meter still on the contact terminals,
apply 12VDC to the coil terminals of the relay.
4. The contact terminals should now close and show a
path for power to the electrical elements. If not, the
relay needs to be replaced.

Page 89
Element Resistance Testing
The breakers are wired into each leg of each element.
If an element has a fault, either in the wiring, or in the
element itself, the breaker will trip and power will no
longer be applied to that leg of the element.
When a breaker in the control box has “tripped,” there
may be a problem in the wiring or an element in the
circuit.
The breakers can be manually reset by depressing the
trip button back into place when they are extended. If
the breaker still does not reset, you need to test or
possibly replace an element.
If the element is functioning correctly, you should read
a resistance between 25 and 35 ohms when testing. A
faulty element will read “open” or show little resistance
(less than one ohm), indicating a shortage through the
element.
To test the element:
1. Disconnect elements one at a time from the
connection point on the lower side of the control
box.
2. Using an ohm meter, test the resistance through the
element between the two pins in the plug.
NOTE: You do not have to test the plug attached to
the lower side of the control box.
3. Before replugging the element, check each wire
pin with an ohm meter test lead, placing the lead
on a steel section of the screed frame. If there is
any continuity through the element to the frame, the
element must be replaced.
Heating Elements
Each element is sized to t properly and provide
sufcient power to heat your screed plate to a
temperature that prevents mix from sticking to the lower
surface of the screed plate.
An element assembly consists of four main components:
• The element.
• The wire protector adapter.
• The wire protector.
• The two-pin wire plug at the end of the element
protector.
Each element is covered by a thin strip of insulation
to keep heat from escaping. A support bar and shield
protects the element assembly.
Each element is clamped onto the screed plate to
provide a positive and efcient connection. Enough
pressure should be applied to the element assembly
to sufciently hold it securely against the screed plate
surface.
To remove an element:
4. Remove top cover from the extension screed plate.
5. Loosen all the clamping studs over the element.
6. Remove and replace element.
7. After tightening the clamping stud, lock the clamp by
tightening the stud jam nut.
DO NOT operate an element with a
known shortage. Replace faulty elements and wiring
immediately.
