death.

Exposure Hazard

Always wear personal protective equipment,
including appropriate clothing, gloves, work
shoes, and protection for eyes and ears, as
required by the task at hand.

Explosion Hazard

While the engine is running or the battery is
charging, hydrogen gas is being produced
and can be easily ignited. Keep the area
around the battery well-ventilated and keep
sparks, open ame, and any other form of
ignition out of the area.

• Always disconnect the negative (-) battery cable
before servicing the roller.

• Do not start the engine by shorting the starter circuit
or any other starting method not stated in this manual.
Only use the starting procedure as described in this

manual on Page 4-6 to start the engine.

• Failure to observe these directions could result in

electrocution or death.

Suffocation Hazard

Never operate the internal combustion engine
on this machine in an enclosed area with poor

All internal combustion engines create
carbon monoxide gas during operation and

special precautions are required to avoid

carbon monoxide poisoning:

• Never block windows, vents or other means of
ventilation.

• Verify that all guards and covers are properly attached
before starting the engine. Do not start the engine if
any guards or covers are not properly installed on the
roller.

• If you must run the engine during maintenance
procedures, make sure you have a helper to keep
bystanders clear of the roller and make observations
of moving parts as requested by the operator.

• Always turn the start switch to the OFF position after
operation is complete and remove the key from the
switch. Keep the key in your possession when the
roller is not operating.

• Attach a “Do Not Operate” tag near the key switch
while performing maintenance on the equipment.

• Never operate the engine while wearing a headset to
listen to music or radio because it will be difcult to
hear the warning signals.

SAFETY LABEL LOCATIONS

If your LeeBoy machine has been repainted, it is
extremely important that all decals referring to
CAUTION, WARNING, and DANGER be replaced in their
proper locations. The illustrations on this page will aid
you in determining the proper locations. For additional
help, refer to Section 7, Illustrated Parts List.

A description of location is provided below for each
safety label. For additional instructions, contact your
dealer.

NOTE: It is the responsibility of the owner and

operator to make sure that all safety labels
are readable and located on roller as
designated by LeeBoy.

Safety

Safety Decals Care

• Keep safety decals and signs clean and legible at all
times.

• Become familiar with the content and position of each
safety decal. Decals include important information.

• Replace decals and signs that are missing or become
illegible.

• When replacing parts that display a safety decal,
ensure the new part is also tted with the correct
safety decal.

• Obtain safety decals or signs from your authorized
LeeBoy dealer when needed.

Decal Installation (Sticker Type)

1. Be sure the installation area is clean and dry. Use

hot, soapy water to clean the surface where decal
will be applied. Thoroughly dry.

2. Measure and determine decal positioning before

removing the decal paper backing.

3. Remove the smallest adhesive backing of the split-

backing paper.

4. Align decal over the specied area and carefully

press exposed portion into place.

5. Slowly remove the remaining backing and carefully

smooth the remaining portion of the decal into place.

6. Small air pockets can be pierced with a pin and

smoothed using a piece of the decal backing.

MACHINE SPECIFIC PRECAUTIONS

Hot Material Precautions

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

• Allow machine to cool before repairing or performing
maintenance on 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. Get medical attention as soon as possible.

DO NOT remove radiator cap, drain

plugs, and service grease ttings or pressure taps

when engine is hot. Add coolant to the radiator and
perform other services only when the engine is
stopped and fully cooled.

Hydraulic Systems Precautions

• Make sure 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.

Decal Installation (Top Protected)

1. Be sure the installation area is clean and dry. Use
hot, soapy water to clean the surface where decal
will be applied. Leave wet.

2. Measure and determine decal positioning. Remove
protective backing and soak the decal in clean,
soapy water before application. (This will help to
alleviate air bubbles when applying the decal.)

3. Smooth the decal into place with a squeegee and
check for air bubbles.

4. Small air pockets can be pierced with a pin and
smoothed using a piece of the decal backing.

5. When the decal is completely smooth, carefully
remove the top paper.

Wear proper hand and eye protection
when searching for a high pressure leak. Use a
piece of wood or cardboard as a back stop (instead
of hands) to isolate and identify leaks. Pressurized

hydraulic uid or oil has sufcient force when it

escapes to penetrate the skin, which could cause
serious personal injury. Ensure pressure is relieved
before disconnecting line, hoses and valves.

If injured by concentrated high

pressure steam or hydraulic uid, seek medical

attention immediately. Serious infections or

toxic reactions can develop from hydraulic uid

penetrating the skin’s surface.

LeeBoy Model 400 & 400T Rollers1-8

Safety

Refueling Precautions

• Fuel is highly ammable and should be handled with
care. Death or serious injury can occur due to an
explosion or re.

• When refueling, keep the hose nozzle or the funnel
in contact with the metal of the fuel tank to avoid the
possibility of an electrical spark lighting the fuel.
Maintain control of ller nozzle.

• DO NOT ll tank to capacity. Allow room for expansion
to reduce the risk of fuel expanding and spilling from
the tank.

• DO NOT overll the fuel tank as overow creates a re
hazard when spilled onto hot components.

DO NOT smoke when refueling and

never refuel when the engine is running.

• Tighten fuel cap securely. Should fuel cap be lost,
only replace it with an original manufacturer-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 the correct fuel grade for the operating season.

Battery Precautions

Keep all sparks and ames away from

batteries. Gas emitted by electrolytes is explosive.

Acid propelled by an explosion can
cause blindness if it comes into contact with eyes.
ALWAYS wear safety glasses when working near
batteries.

• If you come into contact with battery electrolyte

solution, wash off immediately. Chemicals can cause
burns.

Tire Precautions

DO NOT mount or demount tires
without proper training. A violent explosion can
occur.

Follow all procedures and safety instructions. Wall
charts containing mounting and demounting instructions
for all rims are available through the United States
Department of Transportation (DOT), Washington, D.C.

When in doubt, contact a qualied

tire dealer or repair service to perform required tire
maintenance.

Inspection

• Clean rims and repaint to stop detrimental effects of

corrosion and facilitate checking and tire mounting.

• Be very careful to clean all dirt and rust from rims.

This is important for securing rims into the proper
position.

• Check rim components periodically for cracks.

Replace all cracked, badly worn, severely rusted, and
otherwise damaged components with new parts of the
same size and type. If you are not sure about proper
mating of tire and wheel parts, consult a wheel and rim
expert.

DO NOT attempt to rework, weld,
heat, or braze any rim components that are cracked,
broken or damaged. Replace damaged components
with new parts of the same size and type. Mixing
parts of one type with those of another is potentially
dangerous.

DO NOT reinate a at tire without
rst inspecting the tire, tube, ap, rim, and wheel

assembly for damage. Be sure parts are secured

before ination.

1

• Always disconnect the battery ground cable before
working on the electrical system to avoid injury from
sparks or short circuit.

• To avoid electrolyte loss, DO NOT tip batteries more
than 45 degrees.

• Use jumper cables ONLY as prescribed on Page
5-11. Improper use can result in battery explosion or

unexpected roller motion.

LeeBoy Model 400 & 400T Rollers 1-9

Demounting

• Do not attempt to demount a tire unless you have the
proper equipment and experience to do the job.

• Remove valve core to exhaust all air from tire.
ALWAYS exhaust all air from tire prior to removing
rim components or wheel components (such as nuts
or rim clamps). Check the valve stem by running a
piece of wire through the stem to make sure it is not
plugged.

Safety

Mounting and Inflation

• DO NOT inate a tire before all components are in
the proper position. Place tire in a safety cage and
inate to approximately 10 psi. Recheck components
for proper assembly. If improperly assembled, deate
and correct.

• Never hammer on a tire/rim assembly that is not fully
deated. If assembly is proper at 10 psi, continue to
inate to fully seat the tire beads, then completely
deate the tire to prevent localized overstretching
of the tube. Reinate to recommended operating
pressure.

• NEVER sit on or stand in front of a tire/rim assembly
during ination. Use a clip-on chuck and make sure
ination hose is long enough to stand to the side of the
tire while inating.

• DO NOT hammer components with steel hammers.
Use rubber, lead, plastic or brass-faced mallets to tap
components together.

Operation

DO NOT inate tires beyond the maximum
recommended ination pressure.

NEVER run a vehicle one single tire of a dual assembly
as the carrying capacity is dangerously exceeded and
can result in damage to the rim and tire

Mismatched rim parts are dangerous

and can cause severe injury.

• Latch seat belt (if equipped) and adjust to t snugly.

• Only start and operate the machine from the

operator’s seat. DO NOT bypass paver/nisher‘s
neutral-start system. If the system malfunctions, it
must be repaired.

enclosed area without proper ventillation. Exhaust
gasses are odorless and deadly.

DO NOT operate the engine in an

Parking Precautions

• Park roller on level ground whenever possible. On
grades, park machine with wheels securely blocked.
Always apply parking brake.

• Before leaving operator’s station:

1. Place left drive handle in neutral.

2. Turn off all accessories.

3. Set emergency brake.

4. Shut off engine.

• Always remove ignition key when leaving roller parked
or unattended.

Operating Precautions

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

Starting and Stopping Precautions

• Check all around the roller 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.

Check brakes, steering and other
control devices in accordance with instructions
before starting. Be sure emergency brake is applied
and the left Drive Throttle is in neutral.

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

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

DO NOT stand between the equipment

and the truck while the truck is being coupled with

the paver/nisher. Death or serious injury can result

from being crushed between the two machines. DO
NOT ride on attachments.

LeeBoy Model 400 & 400T Rollers1-10

Safety

Some work situations require more
attention to stopping distances, particularly when
going downhill. Steeper grades require longer
stopping distances. Familiarize yourself with
these variables so you can anticipate when longer
stopping distances are required.

• 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 roller motion
as quickly as possible. Apply emergency brake and
keep the machine securely parked until the failure is
corrected or the machine can be safely towed.

• Drive the machine with care. Make sure speed is

compatible with conditions. Use caution on rough
ground, slopes and while turning.

• 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 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

while on the road with the machine. Operator must
also understand which circumstances require use of
each light signal.

• When required, provide an escort for roading.

• DO NOT tow the Model 400 roller, except to remove

from road or load on a trailer. The Model 400T is
equipped for towing.

Maintenance Precautions

• DO NOT attempt repairs unless trained to do so.

Refer to manuals and experienced repair personnel

for help.

• Before conducting maintenance, 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 roller is in motion or while engine is operating. If
lubrication or mechanical adjustment is necessary:

1. Place left drive handle control in neutral.

2. Apply emergency brake.

3. Shut off engine.

4. Place equipment in a safe position.

5. Use extreme caution.

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

• When inating tires, use a self-attaching ination
chuck with remote shut-off.

• 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.

• Refer to Section 5, Maintenance, for more detailed

information.

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 2-3. 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)

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

respect to the wrench

TS = TD * L / LH

OR

Figure 2-4. 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

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 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
(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:

Information and Specications

Example 2 Flats

difference

Figure 2-5. 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.

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.

Operation

MACHINE OPERATION

NOTE: Refer to the engine manufacturer’s operation

and maintenance manual for instructions

when starting engine for the rst time. Follow

engine manufacturer’s recommendations for
fuel and oil.

Engine Start-Up

The Directional Control (FNR) lever
must be set in the NEUTRAL position before starting
engine.

DO NOT operate the starter longer
than 20 seconds. If the engine does not start, allow
the starter to cool for two to three minutes.

1. Set throttle to full open which is toward the front of

the roller.

2. Insert key into ignition switch and turn clockwise

to the START position. Release key when engine
starts.

3. Let engine idle for 30 seconds, then set the desired

throttle speed.

4. Check indicator and gauge operation.

5. Return to neutral position and turn ignition key

counterclockwise to shut down engine.

Cold Weather Engine Warm-Up

In cold weather, keep the fuel tank

lled to reduce the chances for condensation and
corrosion. Do not ll the fuel tank to capacity. Leave

room for fuel expansion.

In cold weather, it is extremely
important to allow the engine and hydraulic oil to
warm up before activating components.

• Run engine for ve minutes.

• Operate each of the hydraulic functions before

moving machine.

Directional Control

The LeeBoy Model 400 and 400T Rollers are
designed to operate from forward to reverse with
a single drive lever. There are, however, two drive
levers: one on each side of the steering column.

These levers are inter-connected and arranged in this
manner for the operator’s convenience.

• Move lever from NEUTRAL (N) to FORWARD (F)

position to move roller forward. Move lever backward
from NEUTRAL (N) to REVERSE (R) position to move
roller backwards.

• Move lever further away from NEUTRAL (N) position

to increase ground speed. Move lever closer to
NEUTRAL (N) position to decrease ground speed.

Engine Warm-Up

Allow engine and hydraulic oil to warm

up before activating components.

1. Start engine and let it idle for several minutes. Do
not accelerate rapidly during warm-up.

2. Operate the engine at less-than-normal loads and
speeds until engine reaches normal operating
temperatures.

Running the engine at high RPMs will

shorten its useful life.

NOTE: See engine manufacturer’s operation and

maintenance manual for more information.

When operating on an incline, the
roller may start to pull downward. Increase the
throttle setting, move drive lever towards NEUTRAL,
or a combination of the two, will counteract the pull.

Maintenance

ELECTRICAL SYSTEM

The electrical system is a 12-volt negative ground
system. The battery is located on the right side of the
operator’s platform behind the disconnect switch.

Battery Servicing

Batteries contain sulfuric acid that

produces explosive gases. DO NOT allow ames or

sparks near the battery as serious injury can result.

Always wear safety goggles and

protective clothing when servicing the battery.

In case of acid contact with skin or eyes, ush

immediately with water for a minimum of 15 minutes
and get prompt medical attention.

When servicing batteries, ALWAYS

disconnect the negative (-) (ground) cable rst and

connect it last. Generally, if the negative cable is
grounded during removal, sparks will not occur.
If the positive cable is grounded during removal,
sparks will occur and could ignite explosive gases.

NOTE: The electrical system is a negative ground

system. Connect the positive (+) cable to the
positive (+) post of both batteries. Connect
the ground (-) cable to the negative (-) post of
both batteries.

2. DO NOT attempt to polarize alternator.

3. Make sure alternator wires are correctly connected
before connecting battery terminals.

4. DO NOT ground alternator output terminal.

5. DO NOT disconnect or connect alternator wires
while batteries are connected or while alternator is
operating.

6. Connect batteries or booster battery in the correct
polarity [positive (+) to positive (+), negative (-) to
negative (-)].

7. DO NOT disconnect batteries when engine is
running and alternator is charging.

8. Disconnect battery cables before connecting
battery charger to batteries. Charge batteries
separately.

Battery Maintenance

Perform maintenance on the battery as follows:

1. Disconnect battery clamps, disconnecting the black
(grounded) clamp rst.

Hold Down Bar

Battery

Negative Terminal

5

NOTE: When replacing the batteries, discard the old

batteries properly.

Be sure the terminals and battery posts are thoroughly
cleaned and that battery cable terminals are tight.
Dirty or loose connections can create high electrical
resistance and permit arcing.

Keep the battery clean by washing it off whenever dirt
build-up is excessive. If corrosion is present around
terminal connections, remove them and wash with an
ammonia solution or a solution consisting of 1/4 pound
(0.11 kg) baking soda and one quart of warm water.

Make certain the vent caps are tight to prevent solution
from entering the cells. After cleaning, pour clean water
over the battery and surrounding area to wash the
solution away. Check vent cap breather openings to
make sure they are open.

When batteries are connected, follow these rules:

1. Disconnect negative (-) battery cable when working
on or near the alternator.

Positive Terminal

Figure 5-5. Battery Components

2. Clean terminals with a stiff brush or battery service
tool. (Figure 5-6)

3. Apply grease at the base of the battery terminals to
prevent gas from escaping.

4. Install and tighten battery clamps, connecting the
black (grounded) clamp last.

Maintenance

Check Battery Electrolyte Level

NOTE: If water is added to batteries during freezing

weather the battery must be charged imme­diately to prevent freezing. Charge battery
using a battery charger or by running the
engine.

1. If using serviceable batteries, ll each cell to
specied range with distilled water. DO NOT overll.

2. Check battery charge and charging rate.

3. Shut down machine by turning ignition switch key
counterclockwise to the OFF position.

4. Using a multimeter, check the battery charge by
placing the positive (red) multimeter lead on the
positive (+) battery terminal, and the negative (black)
multimeter lead on the grounded (-) battery terminal.
With the multimeter set at the 12 Vdc setting, the
battery should show a charge of at least 12 volts. If
not, charge the battery or perform a load test.

5. Start the engine. From the operator’s seat, check
the battery charge level. The multimeter should
read at least 13.5 volts. If the multimeter does
not indicate minimum charge, check the machine
charging system.

Cold Weather Starting

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.

If a booster battery is necessary for cold weather
starting:

1. 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.

2. 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 machine with the dead
battery.

Fuses And Circuit Breakers

The fuse block is mounted inside the instrument control
panel to the left of the operator’s seat. The blade­type fuse color codes are listed in Table 5-3. Circuit
breakers are mounted on the back of the ignition control
panel.

Alternator

The alternator supplies electrical current for charging
the battery to supply power to the electronic controls.
The built-in regulator in the alternator controls the
voltage output. If for any reason the wires must be
disconnected from the alternator, mark them so that
they can be reconnected properly.

Use the following precautions to prevent damage to the
alternator and/or regulator:

• An alternator should never be polarized. Never
ground any alternator terminals or circuits.

• Always disconnect the battery before disconnecting
or connecting the alternator. Never disconnect the
alternator while operating. Be certain the wiring is
properly connected before connecting the battery.

Replace fuses and circuit breakers
with correct amperage to prevent damage from
system overload.

When a circuit breaker opens due to short circuit or
overloading, turn off lights and place ignition switch
in the OFF position. Wait one minute before starting
machine or turning on lights. The circuit breaker will
automatically reset. If the circuit breaker continues to
trip (open), check the electrical system for short circuits
and defective components. Replace the circuit breaker
if necessary.
