How to Change the Backing Pad

Mirka recommends changing the backing pad regularly to help keep the sander in good working condition.

Unplug the Mirka DEROS from the power supply.
Turn the sander over so the backing pad is accessible.
Use the supplied pad spanner on the locking nut between the backing pad and machine.
Hold the machine securely and rotate the backing pad anti-clockwise to remove it.
Fit the correct replacement backing pad and tighten securely.
Check that the pad is correctly fitted before reconnecting the sander to the power supply.

Always use the correct backing pad for your particular Mirka machine. Mirka notes that using an incorrect backing pad can affect the balance and vibration of the tool.
