SPECIFIC SAFETY INSTRUCTIONS FOR BELT & DISC SANDER
1. Sander must be bolted down to a stand or workbench for stability.
2. Make sure there are no nails or foreign objects in the part of the work piece to be sanded.
3. Plan your work to avoid THROWBACKS – if the work piece catches on the sanding belt or disc and is torn
from your hand.
4. Make sure there is no debris between the work piece and its supports.
5. When sanding irregularly shaped work pieces, plan your work support so it will not slip and be pulled from
your hands.
6. Use extra caution with large, very small or awkward work pieces.
7. Never use this tool to finish pieces too small to hold by hand.
8. Use extra supports (tables, saw horses, work stands, etc, for any work pieces large enough to tip when not
held down to the table top.
9. DO NOT use another person as a substitute for a table extension, or as additional support for a work piece
that is longer or wider than the basic sander table, or to help feed, support, or pull the work piece.
10. When finishing on the disc, always press the work piece against the “Down” side of the disc. Sanding
against the side coming up from under the table could damage the work by making it “chatter”, or tear the work
from your hands and throw it.
11. Sand only one work piece at a time.
12. Find and read the WARNING label (see sample on right) mounted on the sander.
13. Clear everything except the work piece and related support devices off the table before turning the sander
on.
14. Plan the way you will hold the work piece from start to finish.
15. Avoid awkward operations and hand positions where a sudden slip could cause fingers or hand to move into
a sanding surface. Keep fingers away from where the belt goes into the dust trap.
