I have a Makita BO4556 palm sander with a broken catch for one of the sand paper clamps, and I have ordered the replacement base (the plastic piece).
How difficult is it to replace that part? It originally looked as though you just unscrewed the four screws on the bottom to take it off, but that doesn't seem to be the case. That just removed the rubber pad piece with its metal plate.
Does the whole unit have to be disassembled to get to the bottom plate? Are there any instructions available?
