How to Fix an Orbital Sander

An orbital sander is a tool used to sand the surface of wood before it is painted or stained. Sanding is an essential step to achieving a smooth surface and a fine finish. The most common problem with an orbital sander is the rotating backing pad. Over time, the pad wears out and will no longer hold sandpaper. When the pad becomes worn, it must be replaced so you can continue to use your sander effectively.

Instructions

- 1
  Unplug your orbital sander before making repairs. This is a step that should become second nature when working on all power tools. An unplugged tool cannot accidentally be turned on, causing painful injuries or electrical shock.
- 2
  Turn the sander upside down so the sanding pad is facing up. Located in the center of the pad are three to four screw holes. The screws can be seen by looking in the holes. The number of screws holding the pad is based on the model of sander you own.

  Use the Phillips screwdriver to loosen and remove the mounting screws that hold the pad in place. Lift the pad off the sander base and set it aside.

  Insert the mounting screws through the screw holes on the new pad. Align the holes on the pad with the holes on the sander base and tighten each screw a little bit at a time until all the screws are completely tightened. This will keep the pad evenly aligned.
