Usage Notes

  • Do not use if conveyor belt is not centered. Belts are expensive and will destroy themselves if they drift too far in either direction.
  • For oily or dense woods (tropical hardwoods, etc), take only very light passes to prevent clogging the sandpaper.
  • Always remove dried glue squeeze outs with a scraper or other tool before coming here.
  • DO NOT USE unless glue has fully dried
  • Use a belt cleaner occasionally to refresh the sandpaper
  • Do not use to remove old finishes.


This sander features overload detection. If the machine detects too high a load, it will automatically slow down the feed. This saves wear and tear on the machine, but may cause burning of the workpiece if you cut too aggressively.

  • The height adjustment on this machine is VERY aggressive. A full turn will raise the table by more than 2mm (a typical cut should be < .5mm). PLEASE USE A MAXIMUM OF 1/8 TURN OF THE HEIGHT WHEEL PER PASS!
  • Make your first cuts with a very slow speed (10 or less). Once you are sure the load is OK you can gradually increase the speed on subsequent passes.
  • When overload detection kicks in, a red light next to the speed control will turn on. IF YOU SEE THIS LIGHT, PLEASE REDUCE YOUR DEPTH OF CUT AND/OR FEED RATE!
  • Like all of our other sanders, sleeves must be above the elbow, and no gloves should be worn. It's pretty easy to get pulled into the rollers.
