Ponceuse Orbital Filaire Dexter 350W - 350OS2.5: Dexter orbital sander pad slipping

Fri, 06 Feb 2026 00:36:32 -0700

My Dexter orbital sander runs and the electric motor spins but for some reason when applying pressure on the pad, the pad hardly spins. Eventually with enough pressure the pad will stop altogether while the motor still runs. This is unrelated to the hook and loop pad not holding the sanding paper disk. Any idea how to fix it?

Hi, the backing plate does have a visible circular line of chafe however it is not grooved or anything.

There is a center screw on the shaft I believe but I could not find a way to open it as it only can spin with the part beneath it.

The device has no lock button.

I belive this maybe a slipping belt issue, either a gone one or covered in dust. However I cannot find a way to get to it, or find a replacement from this seemingly non existant Dexter brand
