SAFETY INFORMATION

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 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

Overloading could result in an

accident or damage. Do not exceed

GVWR or GAWR ratings as found on

the driver-side door cornerpost of

the vehicle. See Loading Section to determine

maximum volumes of spreading material.

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

During the hopper spreader installation

we recommend the addition of an OSHA

compliant Backup Alarm. This alarm is

required for OSHA governed employers.

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.

• While operating the spreader, use auxiliary

warning lights, except when prohibited by law.

CAUTION

Disconnect electric and/or hydraulic power

and tag out if required before servicing or

performing maintenance.

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.

NOTE: Lubricate grease ﬁttings after each use.

Use a good quality multipurpose grease.

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.

Lit. No. 43826, Rev. 01 8 September 15, 2014

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.

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

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.

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.

MATERIAL WEIGHTS

CERTIFICATION

WARNING

Overloading could result in an accident or

damage. Do not exceed GVWR or GAWR

as found on the driver-side cornerpost of

vehicle.

WARNING

New untitled vehicle installation of a spreader

requires National Highway Trafﬁc Safety

Administration altered vehicle certiﬁcation

labeling. Installer to verify that struck load of

snow or ice control material does not exceed

GVWR or GAWR rating label and complies

with FMVSS.

CAUTION

Read and adhere to manufacturer's

ice-control material package

labeling including Material Safety

Data Sheet requirements.

Lit. No. 43826, Rev. 01 10 September 15, 2014

DETERMINING VEHICLE PAYLOAD

1. Install the hopper spreader and optional

equipment according to the 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, snowplows, 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) from

the certiﬁcation label located inside the driver-side

door jamb or door.

4. With the occupants in the truck 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/cu ft) of

the desired material. Divide the weight into the

payload to determine the maximum volume of

material that can be carried.

WARNING

Overloading could result in an accident or

damage. Do not exceed GVWR or GAWR

ratings as found on the driver-side door

cornerpost of the vehicle. See Loading

Section to determine maximum volumes of

spreading material.

7. Compare the maximum volume to determine the

maximum height of the material in the hopper

spreader.

8. Fill the hopper with the material to the calculated

height. Reweigh the vehicle with occupants

and verify the GVW, Front Gross Axle Weight

and Rear Gross Axle Weight are less than the

vehicle's ratings.

9. Repeat Steps 7 and 8 for each type of material.

Material Density

(lb/ft3)

Rock Salt – Dry 80–90

Sand/Salt Mix – Dry 95–120

A 1:1 ratio is recommended for salt/sand mix

to prevent material from freezing.

Weight of spreader and mount must be added to

struck material weight to determine total spreader

weight.

WARNING

Do not overload vehicle. Use chart below

to calculate weight of material. Weights of

material are an average for dry materials.

CAUTION

Never use wet materials or materials with

foreign debris with any of these spreaders.

These units are designed to handle dry, clean,

free ﬂowing material.
