MACHINE PRECAUTIONS

Hot Material Precautions

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

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

• 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.

1

• Wear proper hand and eye protection when checking
for a high pressure leak. Use a piece of wood or
cardboard as a back stop to isolate and identify leaks.

Hydraulic oil under pressure can
cause serious personal injury. Check for oil leaks
with a piece of cardboard. DO NOT expose hands to
possible high-pressure oil. Turn off engine before

attempting to tighten oil lines and ttings.

• Escaping pressurized hydraulic uid has force

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

• 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.

Rosco CSV Variable Width Chip Spreader 1-7

Safety

Refueling Precautions

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

• DO NOT smoke when refueling and never refuel when
the engine is running. Fuel is highly ammable and
should be handled with care. Death or serious injury
can occur due to explosion and/or re.

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

• Tighten fuel cap securely. Should fuel cap be lost,
replace it with an original manufacturer’s approved
cap. Pressurization of the tank may result from use of
non-approved cap.

• Prevent res by keeping the machine clean of
accumulated debris, grease, and spilled fuel.

• Use ultra-low sulfur diesel fuel (ULSD) only.

Battery Precautions

• Keep all sparks and ames away from batteries, as
gas given off by electrolytes is explosive.

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

• If you come in contact with battery electrolyte solution,
wash off immediately. Chemicals can cause burns.

Starting and Stopping
Precautions

• Check all around the machine to make sure there are
no people working on the machine or in its path 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. DO NOT
bypass the chip spreader neutral-start system.

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

Parking Precautions

• Park machine on level ground whenever possible and

apply the parking brake.

• Before leaving operator’s station:

1. Place the truck in neutral and engage the parking
brake.

2. Turn off all accessories.

3. Shut off engine.

• Remove ignition key when leaving the machine parked
or unattended.

• 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.

Determining Proper Torque

LA

L

E

LA

LH

The only reliable method of creating a consistently
leak-free and long-lasting connection is to ensure the
coupling is brought to the proper torque. Using a torque
wrench with crowfoot is the best method, but the ats
method can be used if a torque wrench is not available.

The most straightforward method of determining the
correct torque setting is to multiply the desired torque
by the length of the wrench from the center of the handle
to the center of the drive (L); divided by the length of the
wrench from the center of the handle to the crowfoot
center (LA) as shown below:

L

Figure 2-15. Torque Wrench - Crowfoot

Information and Specications

2

The minimum torque values are
adequate for sealing most applications. Maximum
torque values should never be exceeded.

There are several methods of determining the correct
setting on the torque wrench when using a crowfoot. All
of the methods involve making the setting proportional
to the effective change in length of the wrench multiplied
by the desired nal torque. The equations and
illustration below describe proper measurements.

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

TS = TD * L / √(L2 + E2)

• To estimate the crowfoot size (E)

Figure 2-16. Measurements Needed

LEGEND

L = Distance from center of torque wrench handle to the
center of socket drive

E = Distance from center of socket drive to the center of

crowfoot

LA = Distance from center of torque wrench handle to
the center of crowfoot

LH = Distance from center of torque wrench handle to
the center of crowfoot, when mounted at 90°

TD = Desired torque at the tting

TS = Torque setting indicated on wrench

E = Drive Size * 0.5 + Distance between Drive and

Open End + Wrench Size * 0.5774

Coupling Installation

Use the following steps for proper coupling installation:

1. Determine the correct torque value for your
coupling.

NOTE: Only use the torque values 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.

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.

Example 2 Flats

difference

Figure 2-17. Flats Method Tightening

NOTE: The mark placed on the nut and backup hex

after tightening by hand should rotate during

nal tightening according to the table below.

The nut and backup hex can then be marked
to indicate if the coupling loosens over time.

1. Seal faces must be in contact with the tting fully
tightened by hand before marking ats.

2. The ats method is most accurate for the rst
assembly cycle. For multiple disassembly and
assembly cycles, torque values are more reliable.

COMPONENTS OVERVIEW

The Rosco CSV Variable Width Chip Spreader applies
a uniform, even layer of aggregate without gaps or
overlaps. Equipped with a receiving hopper in the rear,
two belt conveyors carry aggregate to the front spread
hopper that hydraulically extends to a width of up to
16 feet. Computerized controls allow the hydraulic
discharge gates to open and close to deliver aggregate
at a constant rate, while the vibratory hopper improves
discharge uniformity. An economical means of paving
rural roads, parking lots and subdivision streets, the
CSV chip spreader is easy to operate and maintain.
Become familiar with its components before operating
this machine.

Operator Platform

The operator platform allows easy and convenient
access for machine controls and chip spreader
functions. One person can operate the chip spreader
with ease. A dual operator station option is available.
The control panel(s) features a cover that can be closed
to protect operator control components. The control
panel column can also be tilted forward to allow more
room on the platform if needed.

Engine

The CSV Variable Width Chip Spreader is equipped
with a Cummins QSB6.7 Tier 4F diesel engine. The
air cleaner mounted on top of the machine removes
ne particles such as dust, sand, and chaff. The fuel
lter removes contaminants from diesel fuel before it
ows into the injection pump. The radiator mounted
in front cools the engine. The hydraulically-driven fan
removes heat, saves horsepower and reduces noise.
The fan reverses every 30 minutes to clean the radiator
and spins low RPMs when conditions permit. As the
temperature rises, the fan picks up speed.

The CSV chip spreader features the latest in engine
technology. Tier 4 engines comply with emission
requirements established by the U.S. Environmental
Protection Agency (EPA) to reduce diesel particulate
matter (DPM) and other toxins released into the air.
Advanced emission-control devices and low-sulfur fuel
requirements--only Ultra-Low Sulfur Diesel (ULSD)
can be used in this engine--combine with new after­treatment methods. Refer to the Engine Operator’s
Manual accompanying your chip spreader for additional
engine information.

Electrical System

The electrical system is powered by two 12-volt batteries
mounted in a battery compartment on the frame. Each
battery produces 12 volts DC and maintains 1000 cold
cranking amperes (CCA). An engine-mounted alternator
with 130 amperes of charging capacity keeps the
batteries charged during normal operation. The battery
charge rate can be monitored using the voltmeter on the
center operator control panel.

Components

Receiving Hopper

The receiving hopper on the rear of the machine is
hydraulically controlled. When the hopper wings are
fully open, the hopper can hold a payload up to 3.5 cubic
yards (4 cubic meters). The receiving hopper controls
are located on the joystick for ease of operation while
chip spreading.

Conveyors

The conveyors are an important part of the chip
spreader’s aggregate delivery system.

Two motor-driven conveyor belts move aggregate from
the receiving hopper to the spread hopper. Rubber
chute liners seal each side of the conveyors to prevent
spillage of aggregate. Drive, tension and suspension
for the conveyor belts are provided by various pulleys
attached to the conveyor frame. Pulleys and trough
idlers provide suspension and tension adjustment for
each conveyor belt.

Aggregate material is delivered by a dump truck into
the receiving hopper. The chip spreader is equipped
with a positive-latching, hydraulic-release truck hitch
that secures the chip spreader to a pull bar on the
dump truck. Rubber sealing skirts along the receiving
hopper seals the hopper to the truck dump box during
operation.

Once aggregate material is loaded into the receiving
hopper, it then moves via two hydraulic motor-driven
conveyor belts through grizzly screens to the front
spread hopper. The grizzly screens prevent oversized
aggregate and debris from entering the spread hopper.
A feed gate for each conveyor in the receiving hopper
allows more control over the amount of aggregate
being conveyed to the spread hopper in the front of the
machine.

Proper alignment and tension adjustment of the
conveyor belts is necessary for optimum operation and
machine maintenance.

Rosco CSV Variable Width Chip Spreader3-4

Spread Hopper

The spread hopper in front of the machine provides
accurate application of the aggregate to the road
surface. The spread hopper is hydraulically controlled
and extends from eight (8) feet (2.44 meters) to 16 feet
(4.87 meters) wide to meet job specications. Grizzly
screens at the top of the spread hopper prevent
oversized aggregate or other debris from entering the
spread hopper.

An auger shaft inside the
spread hopper rotates to
transfer aggregate outward
to the spread hopper evenly,
driven by a hydraulic motor
through a sprocket gear and
chain arrangement. The
spread roll at the bottom of
the spread hopper moves
aggregate out of the hopper
through the cut-off gates to
spread evenly onto the road
surface. Individual cut-off
gates allow spreading width
adjustments in six-inch
increments to the full width
of the hopper. The operator
can engage or disengage
individual cut-off gates
manually or automatically.

Components

Hydrostatic Drive

The Rosco Model CSV Variable Width Chip Spreader is
powered by a diesel engine with dual-range, hydrostatic
drive system that propels the machine forward or
reverse at varying speeds with dynamic braking action.
Components of the hydrostatic drive system include:

• One variable displacement axial piston pump coupled
to the diesel engine.

• One high-torque, bent-axis hydraulic motor at the front
axle, which receives hydrostatic power from the pump.

The machine offers three operational modes to
accommodate a wide range of chip spreading
requirements:

• Automatic: A programmable mode that allows the
operator to pre-set the maximum ground speed for
accurate and repeatable applications. Top speed in
Low Automatic is approximately 880 feet per minute
(268.2 meters per minute), or 10 mph (16 km/h),
depending upon engine and tire options. At speeds
less than the set maximum speed, the operator has
full control.

• Manual: A programmable mode that allows the
operator to adjust ground speed and direction with the
joystick. Top speed in Low Manual is the same as in
Low Automatic. The receiving hopper, spread hopper
and seat slides must be retracted to operate in Travel
Mode. (Page 4-5)

• Travel Mode: This programmable mode allows the
operator to adjust ground speed for travel between
job sites. The machine’s top speed is 20 mph (32
kph).

Operation

DRIVING THE MACHINE

The CSV Variable Width Chip Spreader is powered
by a diesel engine with a hydrostatic drive system that
propels the machine at varying speeds with dynamic
braking action. The driver can select from three (3)
ground-speed modes to accommodate a wide range
of requirements: Travel mode, manual mode or auto
mode. You can propel the chip spreader via the joystick
after selecting the ground-speed mode on the active
console. (Figure 4-2)

Operation Mode

Travel Mode

Select the travel mode when driving the chip spreader
to and from work sites. Maximum throttle is 2,200 RPMs
with low idle at 900 RPMs in the travel mode. Maximum
speed in the travel mode is 20 mph (32 kph).

Work functions do not operate when in the travel mode.

The operator platform(s), spread hopper and receiving
hopper wings must be fully retracted to allow an active
travel command. If any of these functions are not fully
retracted, the LED light on the travel button will blink red.
When these functions are retracted, the LED light on the
travel button will illuminate green.

If either function is not fully retracted, the machine may
continue to propel, but ground speed will be restricted.

Manual Mode

The manual mode is the default mode. The operator
controls all work and propel functions via the joystick
and keypads. The maximum throttle is 1,800 RPMs and
low idle is 900 RPMs. The machine may reach 10 mph
(16 kph) depending upon speed in relation to torque
condition.

Figure 4-2. Operation Mode Button

The operator propels the machine using the joystick,
which also contains buttons for spreading functions
(Page 3-10), steering with the steering wheel and
stopping by applying the foot brake. Moving the joystick
forward propels the machine forward; moving the
joystick backwards propels the machine in reverse. The
center position is neutral.

You must step on the foot brake, then release, in order
to propel the machine. If you don’t step on the brake
and try to propel in either direction, an error code will
ash on the DP710 display unit in the upper right corner
of the screen. (Page 4-7) Additionally:

• The park brake must be disengaged.

• The joysticks must be in the neutral position.

• One console must be activated. (Page 4-7)

NOTE: If the machine sits idle for 10 seconds after

propelling, the joystick will time out and you
will need to step on the foot brake again.

Before driving on public roads, check
state and local laws that may apply to industrial
self-propelled machines. Additional lights, mirrors,

slow-moving vehicle emblems, or reectors may be

required.

Auto Mode

In the Auto mode, the maximum throttle is also 1800
RPMs and low idle at 900 RPMs, with a speed of up to
10 mph (16 kph). The operator can preset the desired
feet-per-minute (FPM) speed, rock type, size and PSY
(pounds per square yard). Based on these settings, the
onboard computer then controls the main gate opening
according to ground speed automatically while chip
spreading.

When in the auto mode, the speed control function
is always active in the forward direction. Moving the
joystick back toward the center slows the machine
proportionally. The main gate closes and the FPM
speed turns off with the joystick in reverse.

The auto mode offers an “auto resume” feature. The
Plus One control unit keeps track of the distance
traveled in reverse. When the operator moves forward
again, the control system resumes opening the spread
roll and gates.

NOTE: Depressing the chipping button while

stopped disables this function.

Extend/Retract Operator Station

A unique and convenient feature of the CSV Variable
Width Chip Spreader is the ability to hydraulically extend
and retract the operator station platform(s). Extending
the operator platform is an additional safety factor,
making it easier to see in either direction while this
large industrial machine is moving, along with providing
an unrestricted view for accurate chip spreading. The
platform extends 15 inches (38.1 cm).

Diesel Exhaust Fluid (DEF)
After-Treatment System

The CSV Variable Width Chip Spreader is equipped
with a DEF after treatment system that treats post­combustion exhaust gases prior to tailpipe emission.
This system allows greater engine power, higher
torque and fuel economy while decreasing exhaust
pollution. Trapped soot and undesired combustion
gas is periodically burned off through a regeneration
process, activated by the engine’s ECU (Engine Control
Unit). This “particulate matter” is the black smoke, or
soot, that comes out of the exhaust pipe, which causes
air pollution.

The diesel exhaust after-treatment system comprises
of high-efciency ltration of these contaminates
and sensors that monitor soot levels and prompt
the regeneration process. With this higher ltration
efciency, engine combustion increases power density
and lowers fuel consumption.

The DEF system (Pages 5-15) is an important factor in
operating the machine. Keeping the DEF tank lled is
critical to engine operation. (Figure 4-5)

You may hear a pumping sound from underneath the
vehicle after turning off the ignition key, which is a
normal purging of any unused DEF from the system
back into the DEF tank.

Rosco CSV Variable Width Chip Spreader4-6

If the DEF level is low, a warning light will illuminate
on the DP710 digital display unit on the control panel.
(Page 4-13) Be sure the DEF uid in the tank is not
contaminated before relling. Dispose of DEF uid in
accordance with environmental laws.

Never operate the machine with
an empty DEF tank to prevent serious engine and
emission system damage.

PREPARING TO CHIP SPREAD

Chip sealing is the application of bituminous binder
immediately followed by spreading aggregate. The
aggregate is then compacted (rolled) to embed into the
binder. Single or multiple layers can be applied using
various aggregate and binder types depending upon
the pavement distress or trafc situations. Binder types
vary, but are usually polymer-modied emulsions (PME);
performance-based asphalt (PBA) cements; asphalt
rubber (AR), which require hot chips pre-coated with
asphalt; and rejuvenating emulsion.

4

Figure 4-22. Chip Spreading

The Rosco CSV Variable Width Chip Spreader is
capable of spreading a wide variety of aggregate onto
the surface treatment of asphalt pavements. The chip
spread paving technique seals the asphalt surface from
weathering caused by water and air permeation, and
aids in preventing trafc wear to the pavement. It’s a
very economical means of resurfacing roads because it
has a longer life and offers good water drainage.

Rosco CSV Variable Width Chip Spreader 4-15

The CSV chip spreader produces a higher duration
chip seal due to the aggregate separation effect of the
spread roll. The rotation throws larger aggregate ahead
so they land in the asphalt before the smaller particles.
The smaller particles then “chock” the larger particles
into place, thus bonding better with less chance of
loosening by trafc and causing damage to vehicles.

The main advantages to chip seals include:

• Improved Skid Resistance and Durability: Chip

seals provide excellent skid resistance, wear well and
have long service lives.

• Cost-Effectiveness: Chips seals are typically more

cost-effective when properly placed on the right type
of pavement.

• Ease of Construction: Chip seals typically require

less construction time and cause less disruption to

trafc.

Operation

Road preparation before the chip seal work is essential
to producing a uniform surface. The surface should
be well prepared with only minor defects that can be
corrected by the chip seal. Before chip spreading,
perform the following for the best results:

• Repair all holes and depressions.

• Fill and seal cracks.

• Level any pavement bumps and ruts.

• Remove any excess asphalt on patches and joints.

• Clean the full width of the surface to be treated.

NOTE: Patching materials and crack sealants

need time to cure before placing the chip
seal. Whenever possible complete surface
patching well in advance before applying
the chip seal.

Aggregate Selection

Before operating the chip spreader, it is important to
select and understand the compatible sealant and
aggregate materials needed for the job and how they
react with each other. Aggregate (chip rock) selection is
critical for determining which sealant to use, depending
upon the construction project. Aggregate should be
clean, durable and skid-resistant. Larger aggregate is
generally more durable and results in a thicker binder
level. However, if not properly embedded, it can cause
damage to vehicles immediately after application.

Figure 4-23. Chip Spreader Following Binder Truck

There are basically three types of asphalt aggregate
surface treatments used for chip spreading:

• Single-Surface Treatment: This type of treatment

seals minor cracks, prevents wear and aids in
waterproong a surface. It involves a single pass of
sprayed asphalt followed at once by a single layer of
aggregate.

• Multiple-Surface Treatment: This treatment

provides greater surface protection against both
trafc wear and weather. It is made by using two
or more alternating layers of liquid asphalt and
aggregate. Each succeeding layer of aggregate
should be no more than one-half the size of the
aggregate in the preceding layer and sweeping
should be done between applications.

• Sand Seal: This treatment is used to provide a tight

seal against the weather and makes the surface more
skid-resistant. Its construction is similar to a the
single-surface treatment.

Figure 4-24. Aggregate Moving from Conveyor into

Spread Hopper

There are basically three types of asphalt aggregate
surface treatments used for chip spreading:

• Single-Surface Treatment: This type of treatment
seals minor cracks, prevents wear and aids in
waterproong a surface. It involves a single pass of
sprayed asphalt followed at once by a single layer of
aggregate.

• Multiple-Surface Treatment: This treatment provides
greater surface protection against both trafc
wear and weather. It is made by using two or more
alternating layers of liquid asphalt and aggregate.
Each succeeding layer of aggregate should be
no more than one-half the size of the aggregate in
the preceding layer and sweeping should be done
between applications.

• Sand Seal: This treatment is used to provide a tight
seal against the weather and makes the surface more
skid-resistant. Its construction is similar to a the
single-surface treatment.

Most hard aggregates can be used for chip spreading.
Aggregate should meet the following requirements:

Rosco CSV Variable Width Chip Spreader4-16

• It should be as uniform in size as is economical.
Generally, the largest particles should be no more
than twice the size of the smallest particles.

• Aggregates that are one-half inch (13 mm) or less
provide a quieter, smoother road surface. Larger
aggregate provides a more skid-resistant surface but
creates more noise, so it is generally used in non­populated areas.

• The best aggregate shape is cubical. Flat or
elongated shapes may be completely buried in the
asphalt needed to hold the cubical-shaped aggregate.
The fewer at or elongated shapes in the aggregate,
the better.

• Aggregate must be clean. Coatings of dust, silt or
clay prevent adhesion to the asphalt and interfere with
uniform spreading. Both problems will lessen the life
of the surface treatment.

• Aggregate should also be damp for emulsion use
but dry and warm when using hot binders for better
adherence to the asphalt. Surface treatments are
best applied when the temperature is 50°F (10°C) or
above. The surface being treated should also be dry
and warm.

• Asphalt emulsions for surface treatments and seal
coats are either anionic or cationic, which refers to the
electrical charges surrounding the asphalt particles.
Cationic emulsions have a positive electrical charge
while anionic emulsions have a negative electrical
charge. Cationic emulsions set more quickly in high
humidity or cooler weather, while anionic emulsions
work well in low humidity or warm weather conditions.
Consider the availability of suitable liquid asphalts, and
their electrical charge, before selecting aggregate:

• Anionic emulsions with a negative (-) charge
on the asphalt droplets perform best with
aggregates that have positive (+) surface
charges (such as limestone and dolomite).

• Cationic emulsions with a positive (+) charge
on the asphalt droplets perform best with
aggregates that have negative (-) surface
charges (such as siliceous or granite
aggregates).

Operation

Chip Seal Tips

The sequence of chip seal construction is surface
preparation, binder application, aggregate spreading,
rolling (compaction) and sweeping. The following tips
will ensure a successful chip-sealed surface treatment:

• Be sure to have all the aggregate on hand before
starting the surface treatment.

• Follow the asphalt distributor truck closely as the
best results are obtained when spreading aggregate
onto the liquid asphalt within 30 seconds. The chip
spreader should be no more than 100 feet (30 meters)
behind the distributor truck. To see the full line of
Rosco asphalt distributors, visit http://www.leeboy.

com/rosco/products/asphalt-distributors.

• Spread aggregate evenly within 30 seconds of the
asphalt binder application for proper adherence to the
binder. Excess particles can loosen from the adhered
aggregate by trafc and possibly damage vehicles.

• Chip-sealed surfaces are then compacted. Rollers
should follow the aggregate spreading by no more
than 500 feet and should not be operated more than
6 mph (10 kph). Pneumatic-tired rollers, such as the
Rosco Tru-Pac 915, provide even pressure to all
particles with slight depressions in the surface. Steel­drum rollers crush softer particles and degrade the
surface. For more information, visit www.leeboy.com/

rosco/products/compaction.

• Light sweeping should also be done to clean the
surface of excess aggregate before trafc ow is
restored. Be sure the asphalt surface has had time
to set and bond before sweeping (early morning is
a good time to sweep the surface treated the day
before). To see the full line of Rosco brooms, visit

www.leeboy.com/rosco/products/brooms.

Operation

CHIP SPREADING OPERATION

The CSV Variable Width Chip Spreader is propelled
by a hydrostatic transmission with a single two-speed
motor driving the axle. Aggregate is emptied into the
receiving hopper from a typical dump truck and moved
via two conveyors to the spread hopper in the front
where individual gates are hydraulically opened. Within
the spread hopper, a spread roll rotates to provide
consistent, uniform aggregate application to the binding
material sprayed onto the paving surface. (Figure 4-25)

Figure 4-25. Chip Spreading

It is important that operators understand system
functions and controls before operating the machine for
successful results. Pay attention to the DP710 digital
display as the main screen shows the status of various
functions set on the control console. (Page 4-9)

Be sure trafc control operations are in place before
beginning the chip spreading project. As soon as the
chip spreader is in place, line up the asphalt distributor
truck in front.

NOTE: Extend both spread hopper extensions,

navigate to the Settings screen on the
DP710 digital display and perform a “hopper

dump” before lling the receiving hopper,

especially if the machine has not been used
for awhile. This clears any debris or old
aggregate from the hoppers. This is a good
habit if there are multiple operators or a
variety of aggregate used.

Avoid low limbs, power lines and other

objects that can endanger crew or chip spreader.

Checking Application Rate

Checking the aggregate application rate can be
accomplished using the following recommended
method. This method is also used for PSY
calibration:

1. Enter your target PSY rate into the DP710

digital controller. (Page 4-14)

2. Place a tarp measuring one square yard (.84

m2) onto the roadway and apply aggregate

onto it.

3. Weigh the tarp with the aggregate. This is your
actual PSY rate.

4. Enter the actual PSY rate into the DP710 digital
controller.

Always sound the horn before moving
the chip spreader and ensure no people are in its
path. Serious injury or even death can result.

In order for the chip spreader to propel from a stationary
position, remember:

• The park brake must be disengaged.

• The joystick(s) must be in the neutral position.

• The desired operator control console must be

activated (if equipped with dual operator stations).

• You must step on the service brake and release, then

propel forward or reverse using the joystick. (If you
try to propel without stepping on the service brake, an
error code will ash on the DP 710 digital display.)

• If the machine sits idle more than 10 seconds, the

joystick will time out and you must step on the service
brake again.

Operation

Open Receiving Hopper

The aggregate is emptied into the receiving hopper
using a typical dump truck. Before the dump truck
backs up to the receiving hopper, lower the hopper
wings (opens hopper) by pressing the bottom left button
(Down) on the joystick. (Figure 4-26)

Up

Down

Figure 4-26. Hopper

Wings Control

The receiving hopper width is 10 feet

when fully extended. Use extreme caution to prevent

damage or serious injury from trafc and roadside

obstacles while chip spreading.

The operator (or a ground helper) will also need to
open or close one or both of the feed gates in the
receiving hopper. (Figure 4-27) The feed gates
regulate aggregate ow on the conveyors to the spread
hopper. If using only one conveyor, close the other feed
gate completely. If you notice excessive spillage or
overowing at the spread hopper, lower the feed gates
accordingly.

Truck Hitch

The success of the entire spreading function is directly
related to the dump truck hook-up to the receiving
hopper, and care should be taken to ensure accuracy.
The truck hitch provides the means for the truck to be
held in close proximity to the receiving hopper.

Figure 4-28. Dump Truck Hitched to Receiving

Hopper

The dump truck must be compatible to prevent any
interruption of aggregate supply. In general, the
tailgate of the truck bed should be set eight (8) inches
(203.2 mm) inside the retaining rubber skirt of the
receiving hopper when the bed is raised. Frame length,
the overhang of the dump truck bed frame, and the
relationship of the rear wheels to the frame vary among
trucks. Therefore, a thorough check of each truck bed
in relation to the receiving hopper must be made prior to
starting to spread.

Single-axle trucks carry 5 - 7 tons (4500 - 6350 kg)
while tandem-axle trucks carry 11 - 14 tons (9000 ­12,700 kg). Tandem-axle haul trucks are recommended
as the increased capacity requires fewer hook-ups, less
chance of spillage, and more efcient operation. On
large, tandem-axle trucks, the frame, rear wheels and
gate of the dump bed may be on the same vertical line.
Extensions to the truck bed may be necessary to ensure
a proper seal when attaching to the dump truck. Hitches
should be installed to allow a minimum of two inches
(50.8 mm) clearance between the rear truck tire and the
bumper of the chip spreader.

NOTE: Dump trucks should be in good mechanical

condition. Leaking dump trucks can
compromise the seal binder.

Release

Operation

Trucks should drive VERY SLOWLY on the new surface
and never brake sharply to prevent wheel spin and
mat damage. Do not allow trucks to dump chips when
pulling away from the chip spreader, make sharp
turns or drive too fast on a newly-constructed chip
seal. When driving on the fresh mat, the truck wheel
paths should be staggered to assist in embedding the
aggregate uniformly.

Check the aggregate level in the
receiving hopper regularly while chip spreading.
Signal the truck driver to reload as needed.

The CSV Variable Width Chip Spreader is equipped with
a positive-latching, hydraulic-release truck hitch that
secures the chip spreader to the pull bar on the dump
truck. (Figure 4-29)

Latch

Set Operation Mode

The operation mode switch defaults to Manual upon
start-up. In the Manual mode, the operator manually
controls the spread hopper gate openings and
conveyor speed on both sides from the control console.

When you select the Auto mode on the control console
(Page 4-5), the onboard computer will control the
spread hopper gate openings once the desired PSY,
rock size and type, and spreading FPMs has been
entered into the DP710 digital display.

Speed control is always active in the forward direction
while operating in the Auto mode. The control system
will automatically reach and maintain the desired ground
speed. If you move the joystick back toward center, the
machine will slow down proportionately until the joystick
is centered. (Moving the joystick into reverse closes the
spread hopper gates and shuts off the automatic ground
speed control.)

If operating in the Auto mode, the control system will
automatically resume the set operation. You will need
to back up (about four car lengths), then propel forward
for the automatic resume feature to activate.

Conveyors

Two hydraulically-controlled conveyor belts move
aggregate from the receiving hopper to the spread
hoppers. (Figure 4-33) Rubber chute liners on each
side of the conveyors prevent aggregate spillage and
can be adjusted to maintain even contact with the
conveyor belts if needed. (Page 5-9)

One or both conveyors can be operated depending
upon the spread width needed for the job. The
conveyors can be operated in either Manual or Auto
mode and run almost continuously while chip spreading
to keep aggregate ow to the spread hoppers. Select
auto or manual (and conveyor speed in the manual
mode) using the left and right conveyor switches on the
control panel. (Figure 4-34) The center position is off.

speed set by the operator into the DP710 digital display
unit. (Page 4-8) While stationary, the conveyors will
move at a medium-high speed and increase per the set
FPM speed when moving forward.

If operating conveyors in the Manual mode, the conveyor
speed may be adjusted to match spreading needs. The
proper conveyor speed should be set slightly faster than
spread requirements, stopping infrequently to ensure
aggregate does not overow in the spread hoppers.

Operation

The conveyor system can be damaged
by setting the conveyor speed too high, which
causes the conveyors to start and stop continuously
and can shock the system.

Never leave the chip spreader
unattended while the conveyors are operating.

Never allow anyone near the
conveyors during operation as serious injury or even
death can occur.

Augers

An auger shaft inside the
spread hopper rotates to
keep aggregate owing to
the spread hopper evenly.
(Figure 4-35) The spread
roll at the bottom of the
spread hopper moves
aggregate out of the hopper
through cut-off gates to
spread evenly onto the
road surface. One or both
augers can be operated as
needed.

The auger control buttons are located directly above the
conveyor control buttons. Select auto or manual (and
auger speed in the manual mode) using the left and right
auger switches on the control panel. (Figure 4-36) The
center position is off.

Figure 4-35. Auger

When operating in the Auto mode, the augers
automatically enable and function based upon the FPM

will move at a low speed and increase per the set FPM
speed when moving forward.

There are three speeds available using the Up

Spread Hopper Gate Selection

The CSV Variable Width Chip Spreader has two main
spread hopper gate extenstions, each with eight (8)
individual gates that can be opened and closed manually
or automatically. (Figure 4-37) One or both spread
hoppers can be extended or retracted simultaneously,
depending upon the spread width needed for the
job, with a width of up to 16 feet. Each individual gate
controls a one-foot spread-width section of the spread
hopper.

Figure 4-38. Main Gate Controls

To preset the main gate, use the left or right (or both)
buttons to the desired width, which will be displayed
on the DP710 main screen. (Figure 4-38) This will
open the gates to the desired set point regardless of
ground speed. The spread roll will automatically turn on
when activating the chip spread button on the back of
the joystick (Page 3-10). Bringing the joystick back to
neutral will shut off the gates and spread roll.

Individual gate commands can only be made when the
master gate(s) is in an active open position. Figure
4-40 shows the gate control buttons and corresponding
gate cylinders that control spread width in one-foot
increments. After the main gate(s) width has been
set and activated, the individual gate buttons that can
be used based upon those settings will illuminate
yellow. Upon chipping, the yellow-illuminated buttons
will change to green. If operating in the manual mode,
the operator can close any of the individual gates by
pressing the button to the “CLOSE” position, and the
button will illuminate red.

The CSV onboard computer provides full automatic
control of the gates and aggregate ow when operating
in the Auto mode. (Page 4-5) After setting the FPM,
rock size/type and PSY on the Main screen (Page 4-8),
the system automatically adjusts aggregate ow through
the gates. The aggregate spread rate is maintained
regardless of speed variations while chip spreading
as the onboard computer system constantly monitors
and controls ow. The maximum opening position
for individual gates will be mechanically limited by the
position of the main gate(s).

Operation

Chip Sealing

Become familiar with the machine’s response to the
joystick and how the components function as discussed
in the previous pages. Ground speed is proportional to
the joystick movement.

You will primarily use the joystick controls while
spreading, pressing the chipping activation button on
the back of the joystick when approaching the asphalt
binder. (Page 3-10) The gates will close automatically
when the joystick is brought into the neutral position.

Remember these operational tips:

• Adjust the truck hitch BEFORE connecting to the

haul truck. SLOWLY ease the machine forward to
ensure the truck hitch is properly connected. If the
connection is secure, the truck will be pulled along
while spreading. The truck can be released at any
time.

• Check the aggregate level in the receiving hopper
regularly and signal the haul truck driver to raise or
lower the truck bed as needed. Always raise the truck
bed SLOWLY as you watch the aggregate ow along
the conveyors into the spread hopper. Raising the
truck bed too fast can cause excess spillage.

• Always pay attention to aggregate ow and conveyor
speed. An easy method of determining whether the
conveyor speed is correct:

• If operating in the manual mode, ll the spread
hopper, then move the main gate extensions to
the desired width. As the main gates extend, the
aggregate level will lower.

• If operating conveyors in the Auto mode, they
will automatically rell the spread hopper. The

conveyors will automatically start and stop

continuously in the Auto mode.

Operation

TRANSPORTING

If transporting the CSV Variable Width Chip Spreader on
a trailer, the ramp and transporting vehicle must be large
enough to safely handle the size and weight of this large
industrial machine. Only load the chip spreader onto a
trailer with assistance from another person serving as a
ground guide.

Ensure the receiving hopper wings
and spread hopper gate extensions are completely
retracted before loading the machine onto a
transport truck. Also plan the transport route to
avoid low bridges and any other overhead obstacles.

NOTE: The load angle is 11.7 degrees. Anything

more will require use of boards to load the
chip spreader onto a truck trailer.

1. SLOWLY ease the chip spreader up the ramp onto

the transport truck trailer, centering the machine on
the trailer.

2. Block the wheels in both directions.

3. Connect chains to the factory-installed D-Ring ties-

downs on each side of the frame as shown in Figure
4-41 (two behind front tire, one below receiving
hopper). Use enough chains with the strength to
secure this large industrial machine to prevent any
movement during transport.

OPTIONAL COMPONENTS

Dual Operator Stations

An option for dual operator stations is available for the
CSV Variable Width Chip Spreader. (Figure 4-42) Both
operator station platforms can extend and retract. If
equipped with the dual operator stations, you can only
activate one control panel, although the other control
panel maintains some chip spreader functions. (Page

4-8)

Figure 4-42. Dual Operator Stations and Umbrella

Options

Umbrella Option

The umbrella kit option provides shelter from sun and
other weather conditions for the operator. The umbrella
kit assembly includes the mounting bracket and
umbrella frame assembly that can be mounted on either
side of the screed handle.

All-Wheel Drive (AWD)

The AWD option provides additional traction in all
weather conditions. The tires maintain a better grip
on the road during rain or snow, in mud, and on gravel.
Four-wheel drive provides better torque power for
pulling or low-speed climbing and is especially useful
when operating on loose, low-traction surfaces. All four
wheels turns at the same low speed to power through
nearly any obstacle. Four-wheel drive is also benecial
when hauling heavy loads due to the added road
traction.

Rosco CSV Variable Width Chip Spreader 4-25

Operation

Reverse Camera System

A reverse camera system is also available for the CSV
Variable Width Chip Spreader. (Figure 4-43) This
additional safety feature assists operators when moving
in reverse by using the rear camera to see directly
behind the truck.

Figure 4-43. Back-Up Camera

This unobtrusive sensor/camera system features a 4.3­inch LCD color monitor integrated into a rearview mirror
that integrates four ultrasonic sensors with the camera
image. The system provides both audible and visual
obstacle warning. The high-resolution monitor and
ush-mount camera system delivers excellent picture
quality.

Spread Hopper Vibrator

A spread roll vibrator option is available to further
promote aggregate ow, but it is a must when chip
spreading with sand. (Figure 4-44) This option
enhances the chip spreader’s ability to move any
bridged or trapped aggregate through the spread
hopper using increased agitation.

Maintenance

MAINTENANCE SCHEDULE

Before performing any maintenance procedures on the
Rosco CSV Variable Width Chip Spreader, read the review
Safety in Section 1. See Pages 5-6 to 5-8 for lubrication
information and procedures.

Tool Hazard! ALWAYS use tools
appropriate for the task. Be sure to use the correct
sized tool for loosening or tightening parts.

Follow all maintenance schedules and procedures
to maintain the machine in top operating order. The
maintenance schedule begins with 10-hour, or daily,
maintenance intervals and continues through the 1000­hour, or annual, maintenance schedule intervals.

NOTE: When performing any routine maintenance,

always include previous routine
maintenance procedures to the higher
hourly schedule.

Preventive maintenance on the spreader will provide
years of trouble-free operation. Adjustments can be
performed in the eld with ordinary tools.

Engine preventive maintenance, (other than oil, air
and fuel lter changes), can be found in the Engine
Operator’s Manual.

Anytime the spreader has been repainted or the decals
removed, damaged or illegible, replace immediately for
safe operation.

Changing oil and cleaning the
spreader should only be done in a designated area
where the oil and chemicals can be contained.
These by-products should be discarded in
accordance with environmental regulations.

Do not operate a machine that is
in need of repair. Put an information tag on the

Planetary Hub

The planetary hubs should be checked periodically to
ensure they contain the proper amount of gear lube.
Two drain/ll plugs are located on the outer end of each
planetary hub. The planetary hub is mounted on each
side of the front axle. You will need an assistant to
properly check the gear oil level:

1. With assistance from a ground guide, slowly drive
the machine forward until the planetary hub plug is
at the 3 o’clock or 9 o’clock position. (Figure 5-2)

MACHINE ADJUSTMENTS

Some components of the aggregate delivery system
require occasional minor adjustments. DO NOT adjust
any conveyor component during operation.

Use only Rosco LeeBoy parts if
replacing rubber conveyor components. Using
hard rubber, old conveyor belts or any other rubber
containing fabric or reinforcement will cause rapid
conveyor belt wear and eventual failure.

Loose clothing or long hair can be
entangled in machine components. Wear protective
clothing, stay clear of rotating shafts and use caution
when adjusting conveyor belts and other rotating
components.

Receiving Hopper Lagging Skirts

The lagging skirts are mounted at the bottom of the
receiving hopper and can easily be adjusted when
needed to ensure contact with the conveyor belts
immediately above the tail pulley. (Figure 5-4)
Check for clearance between the skirts and the belts
periodically.

Conveyors

Figure 5-3. Changing Drive Axle Oil

Skirt Bolts

Figure 5-4. Lagging Skirt Mounting Bolts

Adjust the lagging skirts when necessary by loosening

Conveyor Belts

Proper alignment and tension adjustment of the
conveyor belts is necessary to deliver proper
system operation and achieve maximum life from the
components. Belt tension is necessary periodically
since normal working stress causes the conveyor belts
to stretch. (Figure 5-5)

Ensure all belt guards are in place to
prevent severe injury from contact with turning belts
and pulleys.

If you notice misalignment or conveyor belt slack, adjust
the conveyor belt immediately to prevent premature belt
wear or damage to other components. To check for
slack, examine the return side of the belt running under
the load. Belts with too much slack will bounce enough
to contact the conveyor frame.

1. Tighten the adjustable idler adjuster nut on the side
opposite the direction you want the belt to move.
For example, to move the belt to the left, tighten the
right adjuster nut. (Figure 5-6)

2. If the conveyor belt is still misaligned after adjusting
the idlers, adjust the tail pulleys rst by extending
(move belt away from adjuster bolt) or retracting
(move belt toward the adjuster bolt). The tail pulley
adjusters are very accessible under the receiving
hopper on each side of the machine. Extend both
tail pulley adjusters slowly and evenly just enough to
eliminate any bouncing. DO NOT overtighten.

Tail Pulley Adjuster

Three pulleys in the conveyor group are adjustable:

• Adjustable Idler

• Head Pulley

• Tail Pulley

Make small initial adjustments,
checking the adjustment before making another
adjustment to avoid overshooting the desired setting.

Special care is taken at the Rosco LeeBoy factory to
align the head and tail pulleys to precise alignment.
Therefore, alignment adjustment should be made rst
on the adjustable idler:

Rosco CSV Variable Width Chip Spreader 5-9

Conveyor Belt Wipers

The conveyor belt wipers are mounted immediately
below the conveyor head pulleys and contact the
conveyor belt. (Figure 5-7) They serve to remove
any material sticking to the belt as it moves toward the
receiving hopper. Periodically check for clearance
between the conveyor belt wipers and the conveyor
belts. You can access the belt wiper(s) via the front
conveyor panels.

Auger and Spreadroll Chains

The auger and spreadroll hopper chains need periodic
adjustment, and should be inspected every 50 hours of
operation.

Generally, the slack of a roller chain should be on the
lower side. (Figure 5-9 and Table 5-3) Adequate
slack (S) is about four (4) percent of the span for normal
drives, but the slack should be about two (2) percent of
the span for the auger chains:

• Vertical drive or close to vertical drive.

• Center distance between two shafts is greater than

three (3) feet.

• Chain is operated under heavy load and high
frequency of on and off drive.

• Direction of the drive is often changed.

Auger and conveyor chains must have

a slack of 1/4 to 3/8 inches. To measure deection,

exert 40 - 60 pounds of force to chain in either
direction.

To adjust the conveyor belt wipers, loosen the bolts
across the channel strip and move the wiper up until it
touches the conveyor belt.

Conveyor Chute Liners

Rubber chute liners are located
on each side of the conveyor
belts to prevent aggregate
material from leaving the
conveyors. (Figure 5-8) They
should also be periodically
adjusted to touch the conveyor
belts evenly along the entire
length of the conveyor belts.

Adjust the chute liners when
necessary by loosening the
channel strip bolts and moving
the rubber liner until it touches
the conveyor belt.

Maintenance

To accurately check the engine lubrication oil level, park
the machine on a level surface and stop the engine:

1. Clean around the engine lubrication oil dipstick

before removing it from the engine. (Figure 5-13)

2. Removing dipstick from the engine, wipe with a
clean cloth, then reinsert.

3. Pull dipstick out of the engine and check that oil
level is near the full mark on the dipstick.

4. To add oil, remove the ll cap located next to the
dipstick. Twist to remove cap and twist to install (use
15W40 motor oil).

Change Engine Oil and Filter

The engine lubrication oil and oil lter must be changed
at the same time.

DO NOT change the engine lubrication

oil lter while the engine is running. Serious engine

damage will occur.

To change the engine lubrication oil:

1. Park the machine on a level surface and turn off the
engine.

Change the engine lubrication oil while
the engine is WARM, not hot. Hot oil can cause serious
personal injury.

2. If needed, wait until the engine lubrication oil has

cooled a little. Oil should be warm, not hot.

3. Place a container large enough to hold 17.6 quarts

(16.6 liters) of oil underneath the drain hose.

4. Remove oil plug under engine and drain all engine

oil into the container.

5. After all the oil has drained, reinstall the oil plug.

6. Wipe the area around the oil lter and its mounting

base with a clean cloth.

7. Place the empty container under the lter element.

13. Fill the engine with 17.6 quarts (16.6 liters) of oil at

the oil ll cap.

14. Check oil level using the oil dipstick. Add more if
needed.

15. Dispose of used oil in accordance with local and
federal environmental laws.

NOTE: Discard the used rubber gasket with the lter

element.

Engine Drive Belt

Check the engine belt every 250 service hours. The
engine drive belt should be replaced whenever the
belt appears frayed or cracked. This belt drives the
alternator and the cooling fan. Tension on the belt is
maintained by a spring-loaded tensioner.

Engine must be turned off and the
wheels blocked to prevent motion when servicing the
machine to prevent serious injury or death.

NOTE: The spring-loaded belt tensioner must be

pivoted away from the drive belt. Pivoting
in the wrong direction can damage the
tensioner.

To replace the belt:

1. Turn off engine and block the wheels to prevent

movement while working on the machine.

2. Using a 3/8-inch square drive, lift the tensioner

to relieve pressure on the belt. Remove the belt.

(Figure 5-14)

3. Using a 3/8-inch square drive, lift the tensioner and

Air Filter

Turbo-charged engines are especially demanding on air
lter performance. The operator should be continually
aware of the condition of the air lter system. Inspect
all components for damage, cracked hoses or loose
clamps. Replace the lter every 100 service hours. The
air lter is mounted on top of the engine sound shield
between the two conveyers. (Figure 5-15) A restriction
indicator is mounted on the side of the outlet that should
be checked often. If the red indicator is visible, the air
cleaner element must be replaced.

Radiator Coolant

Check the radiator daily to ensure the radiator is full
and that no debris is present as this could block the
system and cause overheating. (Compressed air can
be used to remove any debris from the radiator.) You
can access the radiator surge tank ll cap via the front
access door between the two conveyors.

When the engine is cold, the coolant level should cover
the radiator core. If low, ll with a solution of 50 percent
water and 50 percent ethylene-glycol antifreeze. Flush
the radiator system every 500 service hours (see your
Engine Operator Manual for more information).

DO NOT remove the radiator surge
tank cap while the engine is still hot. The radiator is
under pressure and the hot water can cause serious
injury.

Avoid prolonged and repeated skin
contact with used antifreeze as contact can cause
skin disorders or injury. Wash thoroughly after any
contact.

ALWAYS wear eye protection when
using compressed air to prevent injury.

Figure 5-15. Air Filter Box

1 - Precleaner

2 - Indicator

As the air lter becomes more clogged, the air pressure
increases, causing the indicator to illuminate. When
this occurs, the air lter must be cleaned or replaced as
follows:

Be sure to clean the inside of the air

cleaner body before replacing the air lter element.

Be careful not to introduce any contaminants into the
engine intake tube.

1. Open clamps securing the cover on the lter
housing, then remove the cover.

2. Remove the lter cartridge.

3. Replace with the new lter cartridge.

4. Reinstall cover and secure with the clamps.

5. Reset the lter indicator by pressing button on top of
the indicator.

To check the radiator or add coolant:

1. Open the access door to access the radiator surge

tank cap. (Figure 5-16)

2. Remove the cap to check ONLY WHEN UNIT IS
COOL. Coolant level should be visible.

3. If coolant level is low, add coolant. DO NOT overll.

Radiator Cap

Replace Radiator Hoses

Radiator hoses should be replaced if worn or frayed.
Replacement parts are listed in Section 7, Illustrated

Parts List (IPL).

This procedure should only be

performed when the equipment is not operating.

DO NOT remove the radiator cap while
the engine is still hot. The radiator is under pressure.
Removing the cap could cause serious injury.

1. Turn off ignition, remove key, and allow the engine to

cool down before proceeding:

2. Remove the radiator surge tank cap.

3. Drain radiator into a suitable container (5.5 gallons

or 20.8 liters).

4. To remove upper hose, loosen the two hose clamps

and disconnect. If clamps are not damaged, retain
for installation.

5. To remove lower hose, loosen the two hose clamps

and disconnect. If clamps are not damaged, retain
for installation.

6. Install new hoses in reverse order of procedures

above.

Diesel Exhaust Fluid (DEF)
System

The DEF system is an efcient, effective means of
ltering dirt and other contaminates for optimum
machine performance and reducing air pollution from
exhaust emissions. A sensor on the DEF tank header
monitors the level, temperature and quality of DEF in the
tank. The header is mounted on top of the DEF tank and
provides ltered DEF supply from the tank to the after
treatment DEF dosing unit. Both the DEF tank header
and dosing unit have serviceable lters that require
cleaning or replacement. Fill the DEF tank with DEF
uid at any gas station and be sure to keep the tank full.

(Figure 5-17)

Maintenance

Figure 5-17. DEF Tank

The DEF system will automatically purge the uid
from the system after shutting down the machine and
requires no intervention from the operator.

NOTE: Check the ttings around the DEF tank

header for leaks or any signs of damage
regularly. DEF leaks will leave a white

deposit around the ttings.

DO NOT pressure wash or steam
clean this unit to avoid damage the components. Use
compressed air to remove any loose debris.

DEF contains urea, therefore, wear
safety glasses when performing these procedures.
DO NOT get the substance in your eyes. In case of

contact, immediately ush eyes for a minimum of 15

minutes.

Before servicing any component in the DEF system,
allow the DEF system to purge. You will hear the
pumping noise as the system completes the purge cycle
automatically after shutting down the engine.

1. Shift transmission into neutral.

2. Apply the parking brake.

3. Shut off the engine. Wait at least ve minutes after

shutting down the engine for the after treatment DEF
dosing unit to complete its automatic purge cycle.

DO NOT disconnect battery until the
purge cycle has completed to prevent damage to the
unit.

Rosco CSV Variable Width Chip Spreader 5-15

4. Place battery master switch in the OFF position.

(Page 5-19)

It’s important to service the DEF
system in a clean, dust-free environment to prevent
contamination in the DEF tank that can damage the
after treatment DEF dosing unit.

Maintenance

DEF Tank Filter

The DEF tank lter should be cleaned or replaced every
2000 hours, or every two years, whichever is rst. The
lter is the rst point of contact with foreign elements.
To clean or replace the DEF tank lter, remove the DEF
header tank assembly using the following procedures.
The DEF lines are connected using quick-release
ttings and must be disconnected in the order
described below. (Figure 5-18)

NOTE: It is imperative that you disconnect the

plumbing from the header in the exact order
described below to prevent accidental DEF
contamination of the electrical connector.

Wear eye protection, gloves and
appropriate protective clothing to avoid injury. The
coolant lines connect to the after treatment dosing
unit are hot and under pressure. DO NOT disconnect
while the engine is running or before the system has
purged and cooled down after shutting down the
engine. Disconnecting the coolant lines before the
system cools down may cause coolant to spray and
burn skin on contact.

1. Complete Steps 1 - 4 to prepare machine for DEF

system maintenance.

2. Place a container under the DEF tank as a small

amount of DEF may drain from the coolant lines
when disconnected. (Dispose of the uid in
accordance with environmental regulations.) DO
NOT ush the coolant.

3. Use a clean, damp cloth to wipe the unit to reduce

the risk of contamination entering the DEF tank.
Wipe away any spilled DEF while servicing the DEF
tank lter.

4. Disconnect the coolant connectors and cap the
lines to prevent contamination or DEF leakage.
Figure 5-18) (You can also use a pair of coolant
hose pinch-off pliers to clamp the lines. Make sure
the tank coolant hose material is exible enough.)
DO NOT drain the cooling system. DO NOT spill any
coolant into the DEF tank.

5. Disconnect the DEF connector.

6. Disconnect the suction DEF connector.

7. Disconnect the back-ow DEF connector.

8. Disconnect the electrical connector by pressing the
top of the tting.

9. Remove the header from the tank by removing the
six bolts on the metal ring separating the header
from the tank. Slowly and carefully lift the header
out of the DEF tank, exposing the lter unit, to avoid
damaging the lter or other components.

10. Remove the clip, pull the lter cartridge out and
inspect for cracks, damage and contamination
or debris. Clean the lter and reinsert, unless
replacing the lter at service interval or if debris or
damage is evident:

• Discard the lter element and O-ring in
accordance with environmental regulations and
replace with a new lter element.

• Also inspect the after-treatment DEF dosing unit
lter after replacing the tank lter. (Figure 5-19)

11. Lubricate the O-rings with clean DEF uid and install
the new lter element (O-ring side facing outward) in

The DEF dosing unit lter prevents foreign objects that
may be suspended in the DEF from entering the dosing
system, which draws DEF from the tank, pressurizes
it, and delivers the DEF through a dosing valve. Any
unused DEF is then routed back to the tank. The DEF
dosing unit lter should be replaced every 4500 hours
or three years, whichever comes rst. It is located on
the left inside the rear access panel on the driver’s side.

NOTE: Fill the tank to FULL before storing the
chip spreader overnight to reduce moisture
accumulation from condensation in the tank. Fuel
contaminated by water promotes the growth of

microbes that can clog fuel lters and lines over

time.

The operator should NEVER be on or

near the chip spreader while fuel is being added. NO

SMOKING while lling the fuel tank as all fuels for
internal combustion engines are ammable. Fill the

fuel tank only in a designated area where there is

good ventilation and a re extinguisher available.

Fuel Water Separator

Water and dirt that gets into fuel settles into the water
separator. (Figure 5-22) As it collects, a red oat rises.
When the oat reaches the line on the separator, an
error code will appear on the DP101 digital display. It is
important to drain it immediately.

If you run out of fuel, it is important
to pump the water separator to prime fuel injection
lines. Failure to do so can adversely affect
performance.

To drain the water separator:

ELECTRICAL SYSTEM

Battery Servicing

The chip spreader electrical system is a 12-volt negative
ground system. Two batteries are located on the left
side of the machine in a battery compartment directly
below the engine access panel. (Figure 5-23)

Figure 5-23. Batteries

NOTE: The electrical system is a 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 reconnect it last.

Reversed polarity can damage the electrical
system.

Clean terminals and battery posts thoroughly and check
that battery cable terminals are tight. Dirty or loose
connections can create high electrical resistance and
permit arcing, which will quickly burn and pit terminals
and posts.

Keep the battery clean by washing it off whenever dirt
buildup is excessive. If corrosion is present around
terminal connections, remove them and wash with
ammonia solution or a solution consisting of 1/4 lb. (11 kg)
baking soda added to 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.

Batteries contain sulfuric acid and
normally produce explosive gases that can cause

serious injury. DO NOT allow ames or sparks to

come near the battery.

When charging or working near a
battery, always shield your face and protect your
eyes. In case of acid contact with skin or eyes,

ush immediately with water for a minimum of 15

minutes and get prompt medical attention. If acid is
swallowed, call a physician immediately.

When replacing the battery, discard the old battery
properly. Before connecting the battery, be sure the
Master Disconnect switch is turned off. The switch
is located on the conveyor control panel left of the
operator. (Figure 5-24)

When servicing the electrical system
or welding on the machine, always turn the Master
Disconnect switch to the OFF position to disconnect
the ground strap from the battery to prevent damage
to the machine electrical system.

Figure 5-24. Master Disconnect Switch

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.

When connecting a booster battery, if necessary for
cold weather starting, 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 machine
with the dead battery.

DO NOT attach the negative (-) cable
from the booster battery to the negative (-) post of
the dead battery because a spark could cause an
explosion.

Maintenance

Alternator Servicing

The alternator supplies electrical current for charging
the battery that provides electrical power to electronic
controls. The built-in regulator in the alternator controls
the voltage output. (Figure 5-25)

Figure 5-25. Alternator

If the wires must be disconnected from the alternator, be
sure to mark them for proper reconnection.

Use the following precautions to prevent damage to the
alternator for any maintenance performed:

• Always disconnect the battery before disconnecting
or connecting the alternator.

• An alternator should never be polarized. DO NOT
ground any alternator terminals or circuits.

• Never disconnect the alternator while the machine is
operating.

• Be certain the wiring is properly connected before
connecting the battery.

HYDRAULIC SYSTEM

The hydraulic system is composed of two major
component groups--the hydrostatic drive and the
auxiliary hydraulic group. The hydraulic motors and
cylinders use the same hydraulic oil reservoir and
hydraulic oil supply. Solenoid valves, ow-control valves,
dividers and other components allow simultaneous
function and control of all hydraulic systems. A
50-gallon hydraulic tank with suction strainers, charge
pressure and return lters stores and cleans the
hydraulic uid. An oil cooler is mounted in front of the
engine radiator to complete the hydraulic system.

The hydrostatic drive group consists of an axial piston
hydrostatic pump coupled to the rear of the diesel
engine. A high-torque hydraulic motor drives the
planetary front axle. The auxiliary hydraulic group
consists of a single load-sense pump mounted on the
rear of the drive pump.

Independent circuits to the hydraulic motor are provided
for the left and right conveyor drives, hopper spreadroll
and agitator, steering system, power brakes and
gate control. The hydraulic tank is located below the
operator’s seat on the left side of the chip spreader.

ALWAYS use an equivalent grade of

hydraulic uid. Using hydraulic uids that do not

have equal characteristics can result in substandard
performance or possible failure of the hydrostatic
system. Contact your authorized Rosco LeeBoy
dealer if you need assistance.

Always wear eye protection when

inspecting for leaks in the hydraulic system. Never

use your hands to locate leaks as hydraulic uid

under pressure can pierce the skin and cause
serious injury and toxic reaction.

Never attempt makeshift repairs using
tape, clamps or cements in the hydraulic system.
The system operates under extremely high pressure
and such repairs could fail, causing serious injury.

Inspect the chip spreader for hydraulic leaks daily.
Check that all ttings are secure and tight weekly. If
leaking uid is found, it is probably on the pressure
side of the hydraulic system. DO NOT OPERATE the
machine until the hydraulic leak is repaired.

Rosco CSV Variable Width Chip Spreader5-20

Leaks on the suction side of the hydraulic system are

Sight

more difcult to nd and more serious since air or dirt
introduced into the system causes rapid component
wear and eventual failure. Some symptoms of suction
leakage are:

Maintenance

• Hydraulic uid “foaming.”

• Sluggish system operation.

• Unusual noises in the hydraulic pumps or motors.

Checking Hydraulic Oil Level

The hydraulic oil tank and sight gauge is located on the
right side of the machine. (Figure 5-26) The hydraulic
oil ll cap is just behind the left operator platform.

(Figure 5-27)

1. Make sure that the hoppers are retracted so that oil
ows to the tank, ensuring an accurate reading.

2. Wait 10 minutes after engine has been shut down
before checking hydraulic oil.

Oil level is determined by sight gauge.

Hydraulic oil should be added if the oil level falls

below the ll line. Never ll above the black ll line.

Changing Hydraulic Oil

Changing the hydraulic oil removes the accumulation
of dirt, water and mechanical wear particles from the
hydraulic oil reservoir and system. The chemical
structure of hydraulic oil changes after continuous
use, therefore, new oil is important to ensure correct
operation of the hydraulic system.

Hydraulic oil that has oxidized or
contains contamination can shorten the expected
service life of the components in the hydraulic
system.

Use the following procedures to change the hydraulic
oil:

Use extreme caution when removing

the ller cap to prevent foreign matter from entering

the hydraulic tank.

3. If level is low, clean around the hydraulic oil ller cap

before removing to add hydraulic oil to the tank.

4. Fill tank to the black ll line on sight gauge.

5. Screw the hydraulic oil ller cap back onto the
hydraulic tank.

Rosco CSV Variable Width Chip Spreader 5-21

1. Stop the engine. Allow the hydraulic oil to cool
until it is at a warm temperature. Slowly loosen and
remove the hydraulic oil reservoir ller cap. Put a
clean, lint-free cloth over the hydraulic tank ll cap
opening and secure in place with tape.

DO NOT drain the hydraulic oil from
the reservoir when it is HOT. Hot hydraulic oil can
cause serious injury. Drain at a warm temperature
only.

2. Carefully remove the plug from the hydraulic

tank. Use a drain collection container of sufcient
capacity to collect the hydraulic oil underneath.
Allow all of the hydraulic oil to drain into the
container.

DO NOT ll the hydraulic oil reservoir

with new hydraulic oil until the suction strainer has
been serviced.

Maintenance

CHASSIS AND
MISCELLANEOUS

Tires

The tires should be maintained at the proper tire
pressure and checked daily. (Figure 5-30) Tires
should be maintained at 100 - 105 PSI. However, various
operating speeds, road conditions, material truck size,
tire options and other operating conditions may require
different tire pressure.

Use 385/65R Duplex Radial tires for this machine.

If a tire appears to be low, measure the pressure to be
sure of proper ination. Protect tires from exposure to
petroleum products and other chemicals.

• Use proper tire mounting equipment and experienced
personnel for tire repair service.

• Carefully inspect any tire and rim assembly for
damage before inating tire. Contact a qualied repair
service if needed.

Never cut or weld on inated tire/rim

assembly. Heat from welding can cause an increase
in pressure and may result in tire explosion.

Use jack stands on a solid, at surface

to prevent the machine from tipping when it is
raised. Block the remaining wheels using sturdy
wheel chocks. DO NOT lie under the machine while
supported only by a jack. Death or serious injury can
result from improperly supporting a raised machine.

To replace the tires:

1. Loosen lug nuts.

2. Release any air that remains in the tire.

3. Use a jack or hoist to lift the side of the machine.

4. Place supports under the machine.

5. Attach a sling or other support to the tire.

6. Remove the eight (8) lug nuts from the wheel.

7. Release any air that remains in the tire.

8. Using standard tire removal tools, remove the tire
from the wheel.

9. Install new tire on the wheel.

Figure 5-30. Properly Inated Tire

The rim and tire assemblies for the
wheels are very heavy and must be supported when
lug nuts are removed.

Never exceed the tire manufacturer’s

maximum recommended ination pressure.

10. Measure PSI using tire pressure gauge and inate
to the proper PSI.

11. Align the mounting holes with the studs on the hub.

12. Reinstall the eight lug nuts.

13. Torque the lug nuts in a diagonal pattern to 300 ft-lb
(407 N.m).

14. Remove supports and lower jack.

Maintenance

Brakes

Adjust the rear brakes to prevent improper operation of
the automatic slack adjusters, premature lining wear and
reduced brake performance.

Failure to properly adjust brakes

could cause reduced braking performance.

Brake linings contain non-asbestos

bers. Breathing brake dust may cause respiratory

or other health hazards.

When working on brake drums and linings, use the
following precautions:

• Avoiding creating dust.

• DO NOT remove brake drums and linings without

wearing proper protective equipment.

• DO NOT sand, grind, chisel, le, hammer or alter brake
linings without wearing proper protective equipment.

For safe and effective braking, adjust the brakes using
the following procedure:

1. Grease the cam bracket and spider ttings prior to

brake shoe installation.

Hydraulic brake pressure in excess
of 130 PSI can result in failure of the spring brake
chamber, which could result in serious injury or
death.

4. Check the amount of push rod travel. The optimum

push-rod travel should be 2.5 inches (6.35 cm).

5. Check the angle between the slack adjuster and

push rod. With the brakes applied, the angle should
be 90 degrees (+/- 5°).

6. Apply pressure to brakes and check for lining to

drum contact. Using a .010-inch (.25 mm) feeler
gauge, the lining to drum contact should range from
60 to 100 percent during brake application. Ensure
the lining is inside the drum during application.

7. Rapidly release air pressure from the brakes and

conrm that all brakes release quickly to the normal
relaxed position.

A brake drum exceeding its maximum
wear diameter is should be replaced immediately
to prevent serious injury or even death. If in doubt,
contact the brake drum manufacturer.

DO NOT allow grease to come into
contact with brake linings to prevent reduction in
braking performance that can result in serious injury
or death.

2. Adjust the brake slack adjuster until the brake lining

comes into contact with the brake drum. (Figure

5-31)

Brake Slack

Adjusters

Figure 5-31. Brake Slack Adjusters

3. Apply the brakes using normal operating pressure

(the average line pressure should be 90 PSI).

Lighting

Inspect lights for proper operation daily. If a light or
group of lights does not function:

• Check the circuit breaker box panel for a blown fuse.

• Examine all visible wiring connections, ensuring they

are not frayed or damaged, and securely fastened.

• Check lighting mounts for proper ground.

• Remove light lens or casing and check bulb. Replace

if needed.

• Inspect wiring harness for damage (see Schematics

in Section 6).

If broken wires are found, solder together and cover with
a shrink-wrap type of plastic covering (preferred) or
electrician’s tape to prevent contamination of the solder
joint by moisture.

If you make any repairs to the wiring harness on the
broom, always replace or repair the protective loom
covering the wiring to prevent future damage to the
wiring harness. Examine the routing of the harness and
ensure it is not subjected to excessive movement, which
often causes broken wiring.
