A disc sander features circular sandpaper, which you can replace when necessary.

Step 1 – Don Your Safety Gear

Prior to using the disc sander, you should put on your gloves and goggles. Wear them at all times you operate the disc sander. The goggles protect your eyes from any dust particles that might fly off, and the gloves protect your hand.

Do not wear loose clothing, or at least wear an apron to hold back any loose clothing on you. If you have long hair, make sure you tie it back.

Step 2 – Set Up the Disc Sander

Place the disc sander in an area where there is less traffic. Such a position reduces the risk of people bumping into you while you are using the machine.

Before turning on the power switch of the disc sander, make sure that the guard, the protective shield that covers the circular sander, is in place at all times.

Also check if the dust extraction unit is connected. If not, connect it to the disc sander, for this extraction unit extracts or captures any dust particles while you are sanding.

Step 3 – Prepare the Material

To achieve an accurate result, always mark the areas on the material you want sanded. These marks will help you determine if you have reached the desired area or shape you want.

Step 4 – Turn On the Disc Sander

Once you are done setting the disc sander, you can turn it on. Wait for the disc to reach full speed before using the disc sander. When you turn on the disc sander, you will notice that the sander rotates in a counterclockwise direction, so you need to use only the left portion of the disc sander.

Step 5 - Use the Disc Sander

Keep your fingers at least 4 inches away from the sander and always be aware of where you place your fingers while you are using the disc sander.

Carefully place the material you want to sand on the work space or table of the disc sander. Lightly push the material against the rotating disc; move the piece from left to right at the same time. Do not push the material too hard on the disc. You can only use the part of the disc sander that is not protected by the guard. However, only use the portion of the sander that is moving downward.

Keep the materials moving at all times; otherwise friction between the wood and sander will cause the wood to blacken.

Step 6 – Adjust as Necessary

Most disc sanders have tables that you can adjust to different angles. To use this feature, turn off the disc sander first and unplug it. This is to ensure that no accidents will happen.

To sand a material or wood at a different angle, unlock the locking nut located on the side of the work table. Adjust the locking nut to your preference.

When you use the adjusting table, be extra careful because a space is created from the work table to the rotating disc. You then have more room for accidents to happen.
