Directions How to Use the Rotary Disc Sander
A rotary disc sander is a power tool that has a circular sanding surface that is made from a disposable sandpaper pad. You would use a rotary disc sander on woodworking projects, car refinishing projects or any project that would require sanding that cannot be done by hand but does not require the strength of sandblasting. Learn how to safely use a rotary disc sander before working with one.

1
Sweep up any debris in your work area prior to beginning work. A rotary disc sander generates a great deal of force when you place it on a surface, and if you are standing in liquid or on some other unstable surface, you could fall.
-
2
Remove any loose-fitting clothing and put on safety goggles and work gloves. If you would prefer to wear your loose-fitting clothing, use rubber bands to keep any part of your clothing from hanging down into your work area. If you get loose clothing caught in a disc sander, you can injure yourself and damage the sander.

3
Secure the object you will be working on to a workbench using a strong clamp. If the object is too large to fit on a bench but still requires anchoring to be safely sanded, use cement blocks to hold the piece in place.
-
4
Remove anyone who would be in front of or behind the object you are sanding. Not only is there a danger that the piece will come loose from the clamps and be propelled in harm's way, but pieces of debris are continually flying off an object being sanded and the debris could injure anyone in the room.

5
Check the sanding disc adapter to make sure that the disc is firmly in place. If the sander has accessories such as a dust collection unit or a silencer, be sure that they are also securely in place. Installation of accessories and sanding discs can vary from model to model, so check your user's guide for proper instructions.
-
6
Apply the disc slowly to the surface you are sanding. Practice on a test surface prior to doing your actual sanding to be sure you have a feel for how much torque the sander creates.
-
7
Move the sander around the surface in a smooth and consistent motion. If you leave the sander on one spot for too long, your surface will be uneven when you are done.
-
8
Pull the sander completely away from the surface and turn it off from time to time to check on your work.
-
9
Stop to check your clamps, or the positioning of your cement blocks, every so often to make sure everything is still secure as you are working.
