Removing the two-piece sanding plate
(see figure D)

Push the SDS slider for sanding plate release (9) all the way to the right.

Remove the sanding plate (10).

Pull the rear sanding plate (11) downwards by the recessed handles and then pull it off backwards.

If the front tip of the sanding sheet has worn down, the entire sanding plate can be removed, rotated 120° and put back on again for reuse.
