Question: 330 Slow Down

len

I have a PC 330 speedbloc sander. It starts up at normal speed. When I put it in a wood surface and apply a small pressure, it slows down considerably. At no load it is fine. The brushes seem OK.

I did replace the metal grips that hold the sandpaper a while back. The originals formed fatigue cracks!

It's a nice (loud) sander, but it is not reliable. Anybody have any ideas about fixes for the speed problem?

The sander quit working, however first it started to slow down. I think it's the bearing, I removed the 5 screws, however I can't get the two case halves to come apart. What do I need to do to separate the case?

You have to take the bottom sanding plate off? There are four screws for that. Then part #22 in the parts list, which is described as fan, but I think it is more accurately described as a collector to direct the dust, needs to come off. This has two screws, and keeps the two halves together from the bottom.
