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 deflector/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).
