Mandrel No. 53089 is used with the felt polishing tip and wheels. Thread the tip on to the screw carefully. The felt tip must thread down straight on the screw Mandrel, and be turned all the way to the collar.
If
Mandrel No. 25028 has a small screw at its tip, and is used with emery cutting wheels and sanding discs. Higher speeds, usually maximum, are best for most work, including cutting steel, which is shown here.
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.
Before each use, check to make certain that all components are
assembled to accessory shank and that the drum is sufficiently expanded to secure the band during use. If sanding band is loose on the drum during
operation it may "fly" off and strike you or bystanders.
