We require that you read and understand the contents of this manual completely (especially all safety information) before attempting any

procedure contained herein.

THIS SIGN SHOULD ALERT YOU:

The Society of Automotive Engineers has adopted this SAFETY ALERT SYMBOL to pinpoint characteristics that, if NOT carefully followed, can create a safety hazard. When you see this symbol in this manual or on the machine itself, BE ALERT! Your personal safety and the safety of others is involved.

Dened below are the SAFETY ALERT messages and how they will appear in this manual:

(RED)

Information that, if not carefully followed,

can cause death!

(ORANGE)

Information that, if not carefully followed,

can cause serious personal injury or death!

(YELLOW)

Information that, if not carefully followed, can cause minor injury or damage to equipment

Safety

Before attempting any procedure in this book, these safety instructions must be read and understood by all workers who have any part in the preparation or use of this equipment.

For your safety warning and information decals have been placed on this product to remind the operator of safety precautions . If anything happens to mark or destroy the decals, please request new ones from SnowEx.

Never exceed the Gross Vehicle Weight Rating of vehicle. Failure to do so may limit a vehicles handling characteristics.

Never attempt to take a unit off a truck with material in it.

Always keep hands, feet, and clothing away from power driven parts.

Unit must be pinned and locked into position before operating vehicle.

Always shut off vehicle and power source before attempting to attach or detach or service unit Be sure vehicle/power source is properly braked or chocked.

Remember, most accidents are preventable and caused by human error. Exercising of care and precautions

must be observed to prevent the possibility of injury to operator or others!

Never operate equipment when under the inuence of alcohol, drugs, or medications that might alter your

judgment and/or reaction time.

Before working with the spreader, secure all loose tting clothing and unrestrained hair.

Always wear safety glasses with side shields when servicing spreader. Failure to do this could result in serious injury to the eyes.

Never allow children to operate or climb on equipment.

Always check areas to be spread to be sure no hazardous conditions or substances are in the area.

Always inspect unit for defects: broken, worn or bent parts, weakened areas on spreader.

Remember it is the owner’s responsibility to communicate information on safe usage and proper

maintenance of all equipment.

Always make sure personnel are clear of areas of danger when using equipment.

Never weld or grind on equipment without having a re extinguisher available.

Inspect the unit periodically for defects. Parts that are broken, missing or worn out must be replaced immediately. The unit or any part of it can not be altered without prior written permission from the manufacturer.

Always inspect pins and latches whenever attaching or detaching spreader, and before operation of spreader.

Never exceed 45 m.p.h. when loaded spreader is attached to vehicle. Braking distances may be increased and handling characteristics may be impaired at speeds above 45 m.p.h.

Never use wet materials or materials with foreign debris with any of these spreaders. These units are

designed to handle dry, clean, free owing material.

Never leave material in hopper for long periods of time. Be aware that all ice melters are hygroscopic and will attract atmospheric moisture and harden up.

Warning Decal Positions

Model # SP-7550

ROTATING AUGER CAN CAUSE SERIOUS INJURY OR DEATH

• Keep arms, hands, and loose clothing away from auger.

• Shut off control and unplug spreader before servicing.

• DO NOT EXCEED GVWR OF VEHICLE

• DO NOT OVERLOAD SPREADER

• LOAD SPREADER EVENLY

D6546

• Read Owner’s Manual for Installation Instructions.

Operating the Spreader

Model # SP-7550

SPREADER LOADING

WARNING – Do not overload vehicle. Use chart below to calculate weight of material. Weights of material are an average for dry

materials.

Material Weight Per Cubic Ft.

Rock Salt 80-90 lbs.

Sand/Salt Mix 95-120 lbs.

• Warning – Never leave material in hopper for long periods of time as salt is hygroscopic and will attract atmospheric moisture and harden up.

When spreading sand mix, a 1:1 ratio for Sand/Salt mix is recommended to prevent the material from freezing.

SPREADER OPERATION

• The Dual Variable Speed Controller has dual nger-tip dials for maximum performance, digital system status with warning protection and built-

in Vibrator Switch.

• To start, press power switch on controller and spreader will accelerate to speed set on spinner and auger dials.

• To stop, press power on controller to off position.

• Speed of Auger and Spinner may be adjusted separately to get desired ow and spread distance

• The Vibrator Switch is needed for dense material or to increase the ow to the Auger. This eliminates bridging of material in hopper.

• A Material Bafe has been installed in your spreader to stop ne material from free owing. If using dense or damp material, or if more ow is desired, remove Material Bafe. However, it is recommended that the Material Bafe remain in place if using bulk salt.

• It is important that the Inverted Vee not be removed except when servicing.

• If there are any problems while operating the spreader, refer to Troubleshooting Guide.

SPREADING TIPS

• Spread ice melters with the storm to prevent unmanageable levels of ice.

• Never exceed 10 m.p.h. when spreading.

• For a wider pass, increase spinner speed.

• For a heavier pass, drive slower or increase auger speed.

• Never operate spreader near pedestrians.

• Calculate spread pattern when near vegetation.

WARNING PROTECTION

• If audible beeping occurs, read display to identify problem. If display reads “OL” (overload) or “OH” (overheat), shut controller down and

carefully clear jammed auger. If display reads “E1“ this means there is a dead short in system. Do not use until problem is corrected. If display reads “E0” this means that the motor is not getting any power. Check all connections. If display reads “LB” the vehicle battery is extremely

low (possibly caused by a poor or corroded connection) and could damage the system.

• If there are any problems while operating the spreader, refer to Troubleshooting Guide.

DISCHARGE BAFFLE and INVERTED-V INSTRUCTIONS

• The 7550 uses an Inverted-v design over the auger area. This

inverted-v (D5510) is used to reduce load to the auger drive train. It

must not be removed unless servicing the unit.

• WARNING: Always disconnect power source before attempting to

remove material bafe.

• The 7550 uses a discharge bafe (D5517) to reduce material

leakage. It must not be removed unless servicing the unit.

• BAFFLE EXTENSION INSTRUCTIONS

• The Bafe Extension (D-5503) is intended to be used with very dry products that free-ow with little effort. The bafe is designed to

keep these types of materials from leaking out.

• If you plan on using damp/wet materials, you should remove this bafe by removing the self-drilling screws.

D5517

D5510

D5503

• If you are using a sand/salt mixture, remove bafe extension.
