====Overview====
====Operation====
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 with the arm locking handle. 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.
The vacuum former can mold up to a 19"x17" square and to a depth of 7.3".
Molds must slant outwardly slightly to ensure that they can be popped out of the plastic after molding is finished.

==Safety==
* Sanding creates heat due to the friction. keep material moving to prevent damage to the sanding belt/disc.
* Parts of the machine can reach over 300 degrees C. Don't touch the heater or heat shield surrounding the heater.
* Never put your hand in a position that slipping could cause you to make contact with the belt or disc.
* Never put your hand in a position it could be pinched by the molding frame.
* Never reach over the machine while working or turning off the power. This can be very dangerous as you or your clothing could make contact with the spinning belt or disc.
* The formed plastic is very hot and sticky. It could stick to you and continue to burn if you touch it.
* Some types of plastics could give off toxic fumes when heated. Check the SDS before working with materials you are unfamiliar with.
* Avoid kickbacks by sanding on the correct side of the disc. Always sand on the downward side of the disc, which is just left of center on a disc rotating counterclockwise. Sanding on the wrong side is dangerous and can pull material out of your hands.

Make sure to put draft on your form to prevent sticking.
If the plastic is not hot enough it won't pull down over the form.
