Disk Sander

Select correct grade of abrasive sheet.
Table fence and guide must be correctly adjusted and tight. The clearance between sanding disk and table or rest should not exceed one-sixteenth of an inch.
Goggles must be worn.
Sand only on the downstroke side of disk.
Do not hold small pieces in hand. They have a tendency to rotate, with the attendance danger of pulling your fingers against the revolving disk. A few small pieces should be sanded by hand. For a large number, devise a jig to hold them securely.
If you must leave sander before finishing the job, turn off the power.
Stop sander to make adjustments.
Never touch a moving sanding disk.
Stop the sander by shutting off power and sanding a scrap piece of wood.
Never operate the disk sander if the paper is loose. Report the condition to Instructor.
Move the work about to avoid heating and burning a section of the paper.
