For shaping/sanding wood, some plastics, and aluminum. A very versatile tool good for removing both large and small amounts of material depending on what grit sanding disc is on the machine.
- Don't sand or leave anything wet unless you meticulously clean up afterwards, the table will rust.
- For safe control, rest your workpiece on the table if possible. If this is not possible, hold your workpiece and rest your hands on the table (but away from the disc!). The danger is that the disc could grab your workpiece and jerk your hand onto the disc. Please be aware that any part of your hand that gets sanded will be removed, not smoothed.
- The table should be close to the disc, but not touching the disc. If a thin workpiece gets jammed into the gap, both the workpiece and the sander could be damaged. If you must hand-hold a thin workpiece, try sanding on the side of the disk that moves upward.
- Let your workpiece touch the disc and have the disc do the work. If you have to use force to press your workpiece into the disc, the disc is worn out (and unsafe).
- The table can be adjusted anywhere between 90 and 45 degrees.
- Sander can be used with a miter gauge for more precise sanding.
- The small black lever just behind the top of the disc is a brake. Use this lever when you need to stop the disc.
- Periodically cleaning the sanding disc with the big natural rubber stick extends the life of the disc.
- The sander takes 12" adhesive backed discs.
- To change the disc; loosen the table to allow easier access to the disc, peel off the used disc, clean the metal platter with denatured alcohol, peel backing off half of new disc, carefully slip the exposed half of disc between the table and disc, align sanding disc on platter and peel remaining backing off of disc, press disc onto platter to ensure good adhesion, readjust and tighten the table, SAND!
- If the power switch fails in the ON position, try taking it apart and cleaning the burned sawdust out of the contacts. This technique returned the switch to working order on 12/21/2012.
