I need to remove the sanding disc to replace the belt which has come of and can't get to it
Posted by Anonymous on
The drive belt is a toothed rubber belt, which will be 'thrown off' if there is too much resistance to rotation (pressing too hard, or sanding belt not correctly aligned and rubbing against the side).
To access this, it is not necessary to remove the sanding disc.
Remove the two allen bolts on the top which hold the disc belt assembly (NOT the one that clamps the belt drive disc). The whole assembly lifts off, giving access to the drive belt. It is a bit fiddly, but it can be hooked back on the pulleys and the bolts refitted. Good luck!

You did not specify how the sanding discs are meant to be attached to your sander's backing pad. My experience with this type of problem is material from the sanding process builds up on the backing pad and does not allow the sanding discs to adhere properly. If you have a velcro type system, clean the hooks on the sander's backing bad by soaking the pad's face in a plate of paint thinner for 20 to 30 minutes then use a wire brush to remove the rest of the paint physically. For adhesive pads clean the sander's backing pad surface with denatured alcohol. Do not use isopropryl or rubbing alcohol as this may not be 100% alcohol and could contain a lubricant like glycerin. When the sander's backing pad is completely dry and clean it will hold adhesive backed pads fine. Flaky paint is best scraped off before sanding, use a wide putty knife or a paint scaper to remove large flakes before sanding. This will minimize airborne dust and cleanup. For best results with adhesives, always keep your surfaces clean! Good luck and happy sanding! Michael Mittelsdorf

SOURCE: belt won't stay on belt sander
Check first that you have retensioned the belt... i.e. when you removed the other belt, you would have had to pull on a spring-loaded lever to remove the belt tension before you added the new one... make sure the tension lever is flipped back in to ensure the new belt is tensioned...
Next, and the likely problem you are having, is belt tracking... There should be an adjustment knob up near the front of the sander near the front roller, either on top of the front part of the sander, or to the side near the front roller... When you turn this knob, it makes the belt track either left or right over the sander's base. This knob will allow your belt to run square and true and not spin off to one side...You need to adjust the tracking using this knob while the belt sander is running and with the new belt tensioned and in place, so turn the sander upside down, and power it on with one hand, then turn the knob with the other hand whichever way is needed to have the belt track square and in the middle of the rollers. Make small adjustments on the tracking knob to begin with. They can be sensitive at times.
That should stop your belt spinning off to one side.

The rubber backup plate threads on. You can make up a bracket to insert into the 2 larger holes of the plate. You must keep the fan of the edger from turning to unscrew the plate. I use a hard piece of wood or if you are careful, a large screw driver. The plate unscrews counter-clockwise.
