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 specied 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 sufcient 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 overll the fuel tank as overow 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 qualied
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 reinate a at tire without
rst inspecting the tire, tube, ap, rim, and wheel
assembly for damage. Be sure parts are secured
before ination.
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 inate a tire before all components are in
the proper position. Place tire in a safety cage and
inate to approximately 10 psi. Recheck components
for proper assembly. If improperly assembled, deate
and correct.
• Never hammer on a tire/rim assembly that is not fully
deated. If assembly is proper at 10 psi, continue to
inate to fully seat the tire beads, then completely
deate the tire to prevent localized overstretching
of the tube. Reinate to recommended operating
pressure.
• NEVER sit on or stand in front of a tire/rim assembly
during ination. Use a clip-on chuck and make sure
ination hose is long enough to stand to the side of the
tire while inating.
• DO NOT hammer components with steel hammers.
Use rubber, lead, plastic or brass-faced mallets to tap
components together.
Operation
DO NOT inate tires beyond the maximum
recommended ination 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.

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 reectors comply with state
and local regulations. Keep them clean and in good
working order so they can be seen clearly by all trafc.
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 trafc 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

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
