For the BOSS Delta Oscillating Sander
I had a really hard time removing the drum from my oscillating sander! There was no help that I could find online. So if you are having the same problem, check this out!
1. Lie the sander on its side.
2. Locate the black plastic hood. You need to remove this with a screwdriver.

3. Your sander should have come with a hex key. You need it now!
4. Put the hex key in the appropriate hole and use pliers to rotate the nut. The nut turns clockwise to loosen. This is the opposite of the way thing usually loosen!

After time spent with penetrating oil and brute strength, this was a welcome relief!

Go to this LINK and find the part/diagram that can help you.

If it's the kind with a round disk sander and a wide belt sander, as far as I know belts and disks are still available. There is not much else to wear out. Make sure you test it before purchase.

Here's a link to the online manual.
As far as that diagram....didn't you label the wires?
Take a look here, it may help you. circuit wiring , especially the paragraph that begins: "Knowing that electrically common points have zero voltage drop between them is a valuable troubleshooting principle." Also read about resistors. That speed control knob is one.
Hope that helps...
