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.

Model # SP-7550

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.

General Wiring Instructions

Model # SP-7550

Step 1: Take harness assembly and route from the rear of the vehicle to the front. Route harness along frame and attach to frame hole and

frame supports. It is not recommended to attach to fuel or brake lines for obvious reasons. Do not route close to exhaust system or engine, even though Snowex uses high temperature wiring. It still could melt under extreme heat and short the spreader electrical system, as well as the vehicle electrical system.

Step 2: Mount rear plug on bumper using supplied bolts, locate towards the center of the bumper to reduce the amount of debris the tires

will throw to the rear. Important: Apply a small amount of dielectric grease to the plug. Also try to mount so plug faces upward to help keep plugs tightly sealed.

Step 3: Secure harness from the rear to the front using heavy duty ty-wraps or frame clips along the frame and lighter duty ty-wraps

everywhere else.

Step 4: Layout harness portion that connects to the battery along the re wall and fender well. Do not connect power leads to battery yet.

Drill a 3/4” hole in the re wall, or use existing access hole, for the control portion of the harness and route connector and harness through hole. Be sure to check the area on the other side of the re wall to make sure you are not drilling into the vehicle harness

or a control module. Generally you can drill on either side of the steering wheel for a good location.

Step 4A: The power harness from control box to battery will need to be routed from the inside of the cab to the battery – this results from

the large high amperage connector. Route leads with lugs to battery — do not connect power at this time.

Step 5: Connect harness to the back of the controller and mount to a suitable location. NOTE: You may want to contact customer before

mounting controller as some prefer not to have holes drilled into the dashboard. Ty-wrap loose controller harness and move to the engine compartment. Do not mount close to any heater vents.

Step 6: Connect power leads to the battery: Red + Positive, Black – Negative, always connect to the primary battery if using a dual battery

system. Secure loose loom to any other large or medium vehicle harness with medium duty ty-wraps, this will secure wiring harness.

Step 7: Push the ON/OFF button on the controller to check for power ; when that has been conrmed turn power OFF. The electrical portion

of the installation is complete.

Mounting Instructions

Model # SP-7550

Step 1: Remove tailgate from pickup bed.

Step 2: Load spreader on to truck bed and mount spinner assembly.

Step 3: Slide spreader forward until deector/chute assembly makes contact with vehicle. Then, slide spreader back approx. 1” to allow for

proper clearance.

Step 4: Install stop bars using supplied hole patterns (see Fig.2). To achieve the best position, you may need to drill additional holes in bracket in

order to properly position spreader.

Step 5: Now that the spreader is positioned front to back, you will now center it left to right. Looking at the inside front and corner of the lower

frame area, you will notice (4) holes in the bottom of the frame. Using a paint pen or similar marking device, mark hole locations.

Step 6: Before drilling holes, look beneath the approximate area where each hole will be located. Make sure there are no vehicle components

that will be in the path of the drill before doing this step. If there are interferences, you can relocate holes as needed making sure there are at least two forward and two rearward of the front to back centerline.

Step 7: Install and tighten all (4) bolts.

Step 8: Install ratchet straps (see 7550 Mounting System: Strapping Techniques). It is very important for everyone’s safety this strapping method

be used as the standard mounting procedure. (Do not use ratchet straps exclusively.)

Step 9: Connect the spreader power cord to vehicle main power plug mounted at rear of vehicle (see Electrical Installation).
