MAINTENANCE INSTRUCTIONS

1� Keep safety decals and signs clean and legible at all mes.

2� Replace safety decals and signs that are missing or have become illegible.

3� Replaced parts that displayed a safety sign should also display the current sign.

4� Safety decals or signs are available from your dealer’s Parts Department or our Cedar Rapids factory.

INSTALLATION INSTRUCTIONS

1� Clean Surface

Wash the installaon surface with a synthec, free-rinsing detergent. Avoid washing the surface with a soap

containing creams or loon. Allow to dry.

2� Posion Safety Decal

Decide on the exact posion before applicaon. Applicaon marks may be made on the top or side edge of the

substrate with a lead pencil, marking pen, or small pieces of masking tape. NOTE: Do not use chalk line, china

marker, or grease pencil. Safety decals will not adhere to these.

3� Remove the Liner

A small bend at the corner or edge will cause the liner to separate from the decal. Pull the liner away in a

connuous moon at a 180-degree angle. If the liner is scored, bend at score and remove.

4� Apply Safety Decal

a� Tack decal in place with thumb pressure in upper corners.

b� Using rm inial squeegee pressure, begin at the center of the decal and work outward in all direcons

with overlapping strokes. NOTE: Keep squeegee blade even—nicked edges will leave applicaon bubbles.

c� Pull up tack points before squeegeeing over them to avoid wrinkles.

5� Remove Pre-mask

If safety decal has a pre-mask cover remove it at this me by pulling it away from the decal at a 180 degree angle.

NOTE: It is important that the pre-mask covering is removed before the decal is exposed to sunlight to avoid the

pre-mask from permanently adhering to the decal.

6� Remove Air Pockets

Inspect the decal in the at areas for bubbles. To eliminate the bubbles, puncture the decal at one end of the

bubble with a pin (never a razor blade) and press out entrapped air with thumb moving toward the puncture.

7� Re-Squeegee All Edges.

GENERAL SAFETY RULES

MAINTENANCE SECTION

7� Some parts and

assemblies are

quite heavy. Before

aempng to

unfasten any heavy

part or assembly,

arrange to support

it by means of a

hoist, by blocking

or by use of an

adequate arrangement to prevent it from falling,

pping, swinging or moving in any manner which

may damage it or injure someone. Always use

liing device that is properly rated to li the

equipment. Do not li loaded spreader. NEVER

LIFT EQUIPMENT OVER PEOPLE.

8� If repairs require use

of a torch or electric

welder, be sure

that all ammable

and combusble

materials are

removed. Fuel or

oil reservoirs must

be emped, steam

cleaned and lled

with water before aempng to cut or weld them.

DO NOT weld or ame cut on any tank containing

oil, gasoline or their fumes or other ammable

material, or any container whose contents or

previous contents are unknown.

9� Keep a fully charged re exnguisher readily

available at all mes. It should be a Type ABC or a

Type BC unit.

10� Cleaning solvents should be used with care.

Petroleum based solvents are ammable and

present a re hazard. Don’t use gasoline. All

solvents must be used with adequate venlaon,

as their vapors should not be inhaled.

1� Maintenance includes all

lubricaon, inspecon,

adjustments (other

than operaonal control

adjustments such as

feedgate openings,

conveyor speed, etc.)

part replacement, repairs

and such upkeep tasks as

cleaning and painng.

2� When performing any

maintenance work, wear proper protecve

equipment—always wear eye protecon—safety

shoes can help save your toes—gloves will help

protect your hands against cuts, bruises, abrasions

and from minor burns—a hard hat is beer than a

sore head!

3� Use proper tools for the job

required. Use of improper

tools (such as a screwdriver

instead of a pry bar, a pair of

pliers instead of a wrench, a

wrench instead of a hammer)

not only can damage the

equipment being worked on, but can lead to

serious injuries. USE THE PROPER TOOLS.

4� Before aempng any maintenance work (including

lubricaon), shut o power completely. DO NOT

WORK ON RUNNING MACHINERY!

5� When guards and covers are removed for any

maintenance, be sure that such guards are

reinstalled before unit is put back into operaon.

6� Check all screws, bolts and nuts for proper torques

before placing equipment back in service. Refer to

torque chart in this manual.

MAINTENANCE SECTION CONTINUED

11� When baeries are

being charged or

discharged, they

generate hydrogen

and oxygen gases. This

combinaon of gases

is highly explosive. DO

NOT SMOKE around

baeries—STAY AWAY

FROM FLAME—don’t

check baeries by shorng terminals as the

spark could cause an explosion. Connect and

disconnect baery charger leads only when

charger is “o”. Be very careful with “jumper”

cables�

12� Baeries contain strong sulfuric acid—handle

with care. If acid gets on you, ush it o with

large amounts of water. If it gets in your eyes,

ush it out with plenty of water immediately and

get medical help.

13� Hydraulic uid under

high pressure leaking

from a pin hole are

dangerous as they can

penetrate the skin as

though injected with

a hypodermic needle.

Such liquids have a

poisonous eect and can

cause serious wounds. To avoid hazard, relieve

pressure before disconnecng hydraulic lines or

performing work on system. Any uid injected

into the skin must be treated within a few hours

or gangrene may result. Get medical assistance

immediately if such a wound occurs. To check

for such leaks, use a piece of cardboard or wood

instead of your hand. Make sure all hydraulic

uid connecons are ght and all hydraulic hoses

and lines are in good condion before applying

pressure to system. Wear protecve gloves and

safety glasses or goggles when working with

hydraulic systems.

14� The ne spray from a small hydraulic oil leak can

be highly explosive—DO NOT SMOKE—STAY

AWAY FROM FLAME OR SPARKS.

GENERAL SAFETY RULES

INSTALLATION INSTRUCTIONS

6� Do not

weld on

vehicle

frame

as such

welding

can lead

to fague

cracking

and must be avoided. When drilling holes in

frame member, drill only through the vercal

web porons do not put holes in top or

boom anges. Refer to truck manufacturer’s

recommendaons.

7� Be sure that welds between mounng bars and

sill or between mounng angles and spreader

cross sills are sound, full llet welds. Center

mounng angles so that good llet welds can

be made on three sides—and edge bead weld is

not a sasfactory weld for this service. Use 309

rod/wire for carbon steel and 409 steel. On 304

stainless steel bodies use SAE grade 5 bolts—

welding is recommended if type 308 welding rod

is available�

8� Install controls so that they are located of

convenient use. Posion them so that they do not

interfere with any vehicle control and that they

do not interfere with driver or passenger or with

access to or exit from the vehicle�

9� Check for vehicle visibility, especially toward the

rear. Reposion or add mirrors so that adequate

rearward visibility is maintained.

10� Add Cauon, Warning, Danger and Instrucon

decals as required. Peel o any label masking

which has not been removed.

11� Install all guards as required.

12� Check installaon completely to be sure all

fasteners are secure and that nothing has been

le undone.

1� The selecon of the vehicle on which a spreader

body is to be mounted has important safety

aspects. To avoid overloading:

a� Do not mount spreader on a chassis which,

when fully loaded with material to be

spread, will exceed either the Gross Axle

Weight Rang (GAWR) or the Gross Vehicle

Weight Rang (GVWR) for the chassis.

b� Do install the spreader only on a vehicle

with cab-to-axle dimension recommended

for the spreader body length shown.

2� Follow mounng instrucons in the Installaon

secon of this manual. If mounng condions

require deviaon from these instrucons refer to

factory�

3� When making the installaon, be sure that the

lighng meets Federal Motor Vehicle Safety

Standard (FMVSS) No. 108, ASABE S279 and all

applicable local and state regulaons.

4� When selecng a PTO to drive hydraulic pump, do

not use a higher percent speed drive than indicated

in the Installaon secon of this manual. Too high

a percent PTO will drive pump at excessive speed,

which can ruin the pump, but more importantly,

will overheat the hydraulic oil system and increase

the possibility of re.

5� When

truck frame must

be shortened, cut

o only the poron

that extends behind

rear shackle in

accordance with the

truck manufacturer’s

recommendaons. If

a torch is used to make

the cut, all necessary precauons should be taken

to prevent re. Cuts should not be made near

fuel tanks and hydraulic oil reservoirs, fuel, brake,

electric or hydraulic lines and such lines should

be protected from ame, sparks or molten metal.

Tires should be removed if there is any chance

of their being struck by ame, sparks or molten

metal. Have a re exnguisher handy.

INITIAL START-UP

Prior to tesng the unit, check the posion of the ON-OFF control in the cab. It should be in the OFF posion. Do

not load the hopper.

1� Check to be sure that no loose parts or other material are in body, on spinner hopper or on spinner disk.

2� Raise feedgate unl it is completely clear of conveyor.

3� Fill the hydraulic tank with oil. Refer to the Lubricant and Hydraulic Oil Specicaons secon for proper oil.

Check to make sure that the gate valve under the reservoir is fully open (rotate

counter-clockwise to open).

4� If cranksha PTO transmission has been installed, be sure transmission has proper amount of lubricant.

5� Start engine. Engage PTO or actuate electric clutch switch (if applicable). Let the engine run at approximately

1000 RPM for a few minutes, allowing the oil to circulate through the pump and back to the reservoir. In cold

weather, allow greater warm-up me.

DANGER Stay clear of moving machinery.

6� Place the cab ON-OFF control in ON posion and open the spinner control approximately one quarter (Posion

3). Let the unit run unl the air is expelled from the circuit and the spinner is running smoothly. Turn the

spinner knob to the OFF posion.

7� Open the conveyor knob approximately one quarter (Posion 3) on the valve. Let the unit run for a few minutes

unl the conveyor is running smoothly.

8� Check all connecons in the hydraulic system to make sure that there are no leaks.

9� Check hydraulic oil reservoir and rell to maintain level around mid-point of sight gauge. Unit is now ready for

road tesng.

DANGER

Do not check leaks with hands while system is operang as high pressure leaks can be

dangerous! If skin is pierced with hydraulic uid at high pressure seek immediate medical

aenon as uid injected into the skin could cause gangrene if le untreated. Relieve

pressure before disconnecng hydraulic lines or working with system. Make sure all

hydraulic uid connecons are ght and all hydraulic hoses and lines are in good condion

before applying pressure to the system. Wear protecve gloves and safety glasses or

goggles when working with hydraulic systems.

WARNING DO NOT check for hydraulic leaks adjacent to moving parts while system is operang as

there may be danger of entanglement!

HEADERGENERAL OPERATING PROCEDURES

Before taking unit out to use, make a “walk-around” inspecon to ensure that spreader is not damaged, that all

essenal parts are in place and that all fasteners are ght and all guards are in place. Check all controls to be sure

that they are operang sasfactorily.

If material to be spread is not already in spreader, have the unit loaded. With ON-OFF control in OFF posion,

engage pump drive and allow oil to circulate unl it is warm (this may be done while traveling to loading or starng

point). The colder the weather, the more important this “warm-up.”

All spinner speed, ow deector and bae adjustments must be made with ON-OFF control in OFF posion to stop

spinner and conveyor to avoid injury from spinner and/or discharging material.

Set variable speed spinner control to obtain spread width desired. Since spread width is aected by spinner speed,

spinner height, ow deector sengs, bae posions, as well as material granule size, density and moisture

content; proper sengs are gained by trial and experience.

Spinner speed selected should be the lowest required to obtain the desired spread width with the material being

spread. Use of high spinner speeds and aempng to control spread width by means of the external baes will

increase wear and tear on parts and create excessive damage to vehicle nishes through uncontrolled throw and

bounce of materials. It will also degrade materials being spread by causing unnecessary parcle break-up and waste

material�

To increase spread to one side, raise the exterior bae on that side. Raise (swing inward) the interior ow deector

on that side to direct material away from the direcon of spread increase. Lower (swing downward) the interior

ow deector on the opposite side to allow material to fall on the side of the spinner away from the direcon of

the desired spread.

Determinaon of the volume of the material spread in cubic feet per mile (per inch of metering gate opening)

depends upon the hydraulic system with which the spreader is equipped.

NOTE: Close feedgate before loading spreader and when traveling to point where spreading is to be done. Open

feedgate before starng to spread.

GENERAL OPERATING PROCEDURES CONTINUED

In order to determine the spread rates for a parcular truck, the following informaon is needed to perform the

required calculaons:

1� Calculaons require accurate and complete informaon.

a� PTO Data

1. PTO percentage of engine RPM.

2. For calculaons, PTO percentage of electric clutch drive will be 100%.

b� Transmission gear raos.

c� Rear Axle Rao. If two speed, determine both raos.

d. Auxiliary transmission (if so equipped) gear raos.

e� Rear re size and type. From re size and type, re revoluons per mile may be obtained from a re

manual or re distributor. The following lists some typical values:

HIGHWAY TIRES

Tube Type Tubeless Type Tire Revoluons Per Mile

8�25 x 20 9�00 x 22�5 543

9�00 x 20 10�00 x 22�5 523

10�00 x 20 11�00 x 22�5 507

11�00 x 20 492

10�00 x 22 11�00 x 24�5 488

f� Type of spreader conveyor.

g. Displacement of pump in cubic inches per revoluon.

2� Spread Rate Calculaons:

From the data obtained above (1), the spread rate in cubic feet of material per mile per inch of feedgate

opening will be:

Y = PTO x TR x RA x AUX x TRM x CFR x PD

16665

Where: Y = Yield in cubic feet per mile per inch

of feedgate height.

CFR = Cubic Feet per Revoluon delivered

by conveyor�

PTO = Power Take O percentage. = �192 for #2 or #4 conveyor

TR = Transmission gear Rao. = �237 for #5 conveyor

RA = Rear Axle rao. PD =Pump Displacement in cubic inches

per revoluon.

AUX = Auxiliary transmission gear rao.

TRM = Tire Revoluons per Mile.

If the vehicle has no auxiliary transmission and is to be operated in third gear (Rao 2.24), low range rear axle (Rao

8.87), and a #2 conveyor is in the spreader, the equaon would be solved as shown below.

(PTO) (TR) (RA) (TRM) (CFR) (PD)

Y = 47 x 2�24 x 8�87 x 523 x �192 x 2�77

16665

Y = 15.586 Cubic Feet/Mile/Inch of Gate Opening

MANUAL DUAL SYSTEM

When using the manual dual system, conveyor speeds and spinner speeds can be set independently of one another

and will remain relavely constant regardless of truck road speed as long as speed is above low idle. Truck road

speed, therefore, will aect volume of material spread per mile. An increase in truck road speed will decrease the

volume per mile spread while a decrease in truck road speed will increase the volume spread per mile at any specic

valve seng. The following delivery rate chart tabulates theorecal deliveries at various road speeds for various

valve sengs.

NOTE: If other delivery rates are desired, they can be obtained by adjusng metering gate opening accordingly.

Doubling gate opening will approximately double delivery. Changes in gate openings may aect spread paern and

may require changes in bae and deector adjustments.
