Mandrel No. 401 is used with the felt polishing tip
and wheels. Thread the tip on to the screw carefully.
Mandrel No. 402 has a small screw at its tip, and is
used with emery cutting wheels and sanding discs.
To replace a band on the Drum Sander, loosen the screw
without removing it to contract the drum then slide the
old band off. Slide the new sanding band on and then
expand the drum by tightening the screw once again.
Replacing Screw Mandrel Accessories
The felt tip must thread down straight on the screw
Mandrel, and be turned all the way to the collar.
Higher speeds, usually maximum, are best for most
work, including cutting steel. Which is shown here.
Before each use, check to
make certain that all compo-
nents are assembled to accessory shank and that the
drum is sufficiently expanded to secure the band dur-
ing use. If sanding band is loose on the drum during
operation it may "fly" off and strike you or bystanders.
