Training
Overview
The disc sander allows you to sand outside corners and flat surfaces using an abrasive disc. The belt can perform inside corner and flat surface sanding. The table angles can be adjusted to change the angle of cuts. The sanding table can be set between 15 and 45 degrees. The belt arm can be adjusted between 0 and 90 degrees. It is important to inspect the sanding disc and belt for wear before use. If you notice any holes or cuts in a belt let the supervisor know before trying to power the machine. Tears can be caused by leaving material in the same spot too long. Try to keep work moving across the belt/disc to prevent damage. The disc normally won't tear but it will turn dark and have burn marks.
Demonstration
You will need to demonstrate the safe setup and use of the belt/disc sander.

Safety
- Sanding creates heat due to the friction. Be careful not to burn your fingers.
- Never put your hand in a position that slipping could cause you to make contact with the belt or disc.
- Never reach over the machine.
- Use a brush when clearing sawdust from the tables, not your hands.
- Use light pressure when removing material. Never try to force feed the machine.
- Avoid kickbacks by sanding on the correct side of the disc. Do not sand on the right hand portion of the disc.
