Center High Mount Stop Lamp (CHMSL)

Model # SP-8550

• With spreader mounted on vehicle, plug vehicle (CHMSL) harness into spreader stop lamp harness.

• Using supplied harness clamps and screws, route harness along side wall lower corner or so that harness will be out of

the way when spreader is in use.

• Locate vehicle ground wire and stop lamp power wire at rear of vehicle. Use supplied wire taps to connect harness to vehicle electrical system. Once wire taps are installed, check to make sure stop lamp works when brake pedal is pressed. Properly complete installation by tying up any loose wires with ty-wraps, also add electrical tape over both connections to insure a solid electrical connection. Some newer trucks have auxiliary stop lamp power leads already at the rear for these

types of applications.

Mounting Instructions

Model # SP-8550

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 rear 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

Step 8: Install ratchet straps (see V-Maxx 8500 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).

Step 10: Connect Center High Mount Stop Lamp (CHMSL) cord from the spreader to mating half attached to vehicle

BAFFLE INSTRUCTIONS

• The V-Maxx 8550 uses a dual bae design over the auger area. This bae (D6809) is used for dry bulk materials. The bae is designed to reduce the risk of leakage with clean/dry free-owing materials. If the material you are using is damp/wet, you may need to remove bae (D6809). This will allow for more unrestricted ow of materials and possible bridging.

• WARNING: Always disconnect power source before attempting to remove material bae.

• The main bae assembly (D 6808) MUST its original factory installed position unless the unit is being serviced or the Optimum Flow Kit is being installed.

never be removed from

BAFFLE EXTENSION INSTRUCTIONS

• The Bae Extension is installed at the time of assembly. The main purpose of this bae is to keep dry, free-owing material from leaking out.

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

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

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

• 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.

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

• Calculate spread pattern when

8500 CONTROL OPERATION

• The Dual Variable Speed Control 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 switch on controller to o position.

• Speed of auger and spinner may be adjusted separately to get desired ow and spread distance from spreader.

• The Vibrator Switch is needed for dense material or to increase the ow to the auger. This eliminates bridging of material

in hopper.

• In case spreader becomes jammed, it will go into an auto-reverse program to free itself. Auger display will show (AR)

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 “E 0” 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. Also check all other connections as well as this can be a sign of a poor connection elsewhere in the system.

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

AUTO-REVERSE “AR” FUNCTION

• If your controller displays “OL” this could indicate a jammed auger.

• To engage the Auto-Reverse “AR” function:

Step 1: Shut the Main Power Switch OFF for 3 seconds.

Step 2: Turn the Main Power Switch ON. When the machine starts back up the “AR” sequence will automatically start

and the auger will reverse for several rotations to clear the jam.

• After a pause of several moments, the auger will automatically return to correct rotation.

•

If the

jam is still not cleared, the controller will again display “OL”.

• You may repeat Steps 1 & 2 for a second and third time.

• If after the third try the controller displays “OL” — you must extract the material that is causing the problem.

• Follow all warning directions when clearing jams.
