SAFETY PRECAUTIONS

Improper installation and operation could cause

personal injury and/or equipment and property

damage. Read and understand labels and the

Owner's Manual before installing, operating, or

making adjustments.

WARNING

• Driver to keep bystanders minimum of

25 feet away from operating spreader.

• Before working with the spreader, secure all

loose-ﬁtting clothing and unrestrained hair.

• Before operating the spreader, verify that all

safety guards are in place.

• Before servicing the spreader, wait for

auger and spinner to stop.

• Do not climb into or ride on spreader.

WARNING

Do not install the control for this product in

the deployment path of an air bag. Refer to

vehicle manufacturer's manual for air bag

deployment area(s).

CAUTION

If rear directional, CHMSL light, or brake

stoplights are obstructed by the spreader, the

lights shall be relocated, or auxiliary directional

or brake stoplights shall be installed.

CAUTION

During the hopper installation we recommend

the addition of an OSHA compliant Backup

Alarm. This alarm is required for OSHA

governed employers.

CAUTION

Disconnect electric and/or hydraulic power

and tag out if required before servicing or

performing maintenance.

NOTE: Lubricate grease ﬁttings after each use.

Use a good quality multipurpose grease.

CAUTION

• Do not operate a spreader in need of

maintenance.

• Before operating the spreader, reassemble

any parts or hardware removed for cleaning

or adjusting.

• Before operating the spreader, remove

materials such as cleaning rags, brushes,

and hand tools from the spreader.

• Before operating the spreader, read the

engine owner's manual, if so equipped.

• While operating the spreader, use auxiliary

warning lights, except when prohibited by law.

• Tighten all fasteners according to the

torque chart. Refer to torque chart for the

recommended torque values.

WARNING

Vehicles <10,000 lb GVWR: Obstructing the

visibility from the vehicle's rear camera could

result in serious injury or damage. An auxiliary

camera system shall be installed if the

vehicle's rear camera is removed or blocked.

CAUTION

DO NOT leave unused material in hopper.

Material can freeze or solidify, causing unit to not

work properly. Empty and clean after each use.

WARNING

Do not exceed GVWR, GAWR, or maximum

vehicle load capacity, including the spreader

and ballast. See Loading section to determine

maximum volumes of spreading material.

Lit. No. 74146, Rev. 00 5 July 1, 2020

SAFETY

FUSES

The electrical system contains several automotive-style

fuses. If a problem should occur and fuse replacement

is necessary, the replacement fuse must be of the

same type and amperage rating as the original.

Installing a fuse with a higher rating can damage the

system and could start a ﬁre. Fuse Replacement,

including fuse ratings and locations, is located in the

Maintenance section of the Owner's Manual.

PERSONAL SAFETY

• Remove ignition key and put the vehicle in PARK

or in gear to prevent others from starting the

vehicle during installation or service.

• Wear only snug-ﬁtting clothing while working on

your vehicle or spreader.

• Do not wear jewelry or a necktie, and secure long

hair.

• Wear safety goggles to protect your eyes from

battery acid, gasoline, dirt, and dust.

• Avoid touching hot surfaces such as the engine,

radiator, hoses, and exhaust pipes.

• Always have a ﬁre extinguisher rated BC handy,

for ﬂammable liquids and electrical ﬁres.

FIRE AND EXPLOSION

Be careful when using gasoline. Do not use gasoline

to clean parts. Store only in approved containers away

from sources of heat or ﬂame.

WARNING

Gasoline is highly ﬂammable and gasoline

vapor is explosive. Never smoke while

working on vehicle. Keep all open ﬂames

away from gasoline tank and lines. Wipe up

any spilled gasoline immediately.

CELL PHONES

A driver's ﬁrst responsibility is the safe operation of

the vehicle. The most important thing you can do

to prevent a crash is to avoid distractions and pay

attention to the road. Wait until it is safe to operate

mobile communication equipment such as cell phones,

text messaging devices, pagers, or two-way radios.

VENTILATION

BATTERY SAFETY

NOISE

Airborne noise emission during use is below 70 dB(A)

for the spreader operator.

VIBRATION

Operating spreader vibration does not exceed 2.5 m/s2

to the hand-arm or 0.5 m/s2to the whole body.

CAUTION

Batteries normally produce explosive gases

which can cause personal injury. Therefore,

do not allow ﬂames, sparks, or lit tobacco

to come near the battery. When charging or

working near a battery, always cover your

face and protect your eyes, and also provide

ventilation.

• Batteries contain sulfuric acid, which burns

skin, eyes, and clothing.

• Disconnect the battery before removing or

replacing any electrical components.

WARNING

Vehicle exhaust contains lethal fumes. Breathing

these fumes, even in low concentrations,

can cause death. Never operate a vehicle in

an enclosed area without venting exhaust to

the outside.

Lit. No. 74146, Rev. 00 8 July 1, 2020

DETERMINING VEHICLE PAYLOAD

1. Install the hopper spreader and optional equipment

according to the Installation Instructions.

2. Install or attach any other equipment that will be

on the vehicle while the hopper spreader will be

in use (step bumper, trailer hitch, snowplow, etc.).

Fill gas tanks.

3. Obtain the Gross Vehicle Weight Rating (GVWR),

Front Gross Axle Weight Rating (FGAWR), and

Rear Gross Axle Weight Rating (RGAWR). This

information can be found on the certiﬁcation

label located on the vehicle itself, in the vehicle's

owner's manual, or obtained from the vehicle

manufacturer.

4. With the occupants in the vehicle for normal

hopper spreader operation, weigh the vehicle to

obtain gross vehicle weight (GVW).

5. Subtract the GVW from the GVWR to determine

the available material payload.

6. Obtain the weight per cubic yard (lb/yd³) of the

desired material. Divide the weight into the

payload to determine the maximum volume of

material that can be carried.

7. Refer to the Load Volume table and diagram at

left to determine the maximum ﬁll level for the

material.

8. Fill the hopper with material to the calculated level.

Reweigh the vehicle with occupants and verify that

the Loaded Gross Vehicle Weight, Front Gross

Axle Weight, and Rear Gross Axle Weight are less

than the vehicle's ratings.

9. Repeat Steps 6–8 for each type of material.

REMOVE SHIPPING BRACKETS AND

LOCATE COMPONENTS

The spreader is shipped from the factory with its

components secured inside the hopper and the top screen

in place. Before installation of the spreader, remove

shipping brackets and top screen, and locate components.

For 0.35 yd3 hopper spreaders:

1. Take oﬀthe top screen by removing the 3/8" ﬂanged

cap screws and the top screen brackets. Set the

screen and all fasteners aside for reinstallation.

2. Inside the hopper, remove the eight 3/8" steel cap

screws from the two shipping brackets that secure the

chute enclosure to the hopper for shipment. Set the

chute enclosure aside and discard the brackets and

hardware.

3. Install the provided 3/8" stainless steel ﬂanged

cap screws from the parts bag to fasten the

hopper body to the drivetrain.

4. On the shipping pallet, remove the two 5/16" lag bolts

and the shipping bracket that fasten the spinner

deﬂector assembly to the pallet. Remove the 1/4"

hardware that fastens the shipping bracket to the

spinner deﬂector assembly. Set the spinner deﬂector

assembly aside and discard the shipping bracket and

hardware.

UNPACKING THE SPREADER

For 0.7 yd3hopper spreaders:

1. Take oﬀthe top screen by removing the 3/8" ﬂanged

cap screws and the top screen brackets. Set the

screen and all fasteners aside for reinstallation.

2. Inside the hopper, remove the 3/8" steel cap screws

from the four shipping brackets (two on each side) that

secure the chute enclosure and the spinner deﬂector

assembly to the hopper for shipment. Set the chute

enclosure and spinner deﬂector assembly aside, and

discard the brackets and hardware.

3. Immediately install the six supplied 3/8" stainless steel

ﬂanged cap screws from the parts bag to fasten the

hopper body to the drivetrain.
