9.1.1 Disc sanding
Place workpiece firmly against table and ease it into
the moving disc.
If greater precision of angle is needed, place an
angle measuring device on table and against disc,
and adjust the table accordingly. Always tighten
table lock handles.
Do not sand on upward moving portion; disc must
rotate downward into the workpiece.
Do not crowd the work so that the disc slows.
9.1.2 Belt sanding
1. Move belt by hand to ensure that wheels rotate
freely without obstruction, table or tool rest does
not contact belt, and belt tracks properly.
2. Use the entire width of the belt to reduce wear
in one place.
3. At all times, keep hands and fingers away from
pinch points.
