Changing your backup pad regularly helps to keep your Mirka DEROS in tip top condition. You will need the wrench which was supplied with the Mirka DEROS.

  1. Unplug the Mirka DEROS, so there is no power to the machine.
  2. Turn the sander onto it's back, so that the lever is in the base of your hand.
  3. Slide the wrench onto the locking nut between the backup pad and the machine.
  4. While holding the machine and the wrench, rotate the backup pad anti-clockwise.
