Sweeper Back-up Blade Installation                                                       To How-To Instructions >

Back-up Blade Installation
  1. Lay sweeper blade down with the flat side facing up.
  2. Mark the center line of the blade.
  3. Mark 3” from each end of the longest part of the blade.
  4. Measure 1-5/8” up from the bottom of the blade (the aluminum part, not the rubber) at both end marks and the centerline mark.
  5. Check the holes on the back-up blades against these marks for alignment and adjust the marks if necessary.
  6. Drill 1/8” pilot hole, then drill 3/16” hole.  Tap hole ¼ -20. 
  7. Attach back-up blade to sweeper blade with ¼-20 x ½” long bolts and ¼” flat washer.
  8. Apply Loctite 271 thread locker to bolt threads.
  9. Tighten bolts until they are flush with the side of the blade. This will leave the Back-up blade enough room to move up and down freely. 
  10. Adjust the bolt height if necessary.
