The machine-screw threading on Mandrel No. 424 threads into polishing point No. 427. This and other thread- ed mandrels must be screwed firmly down to the collar before being used.

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 sand-

ing band is loose on the drum during operation it may “fly” off and strike you or bystanders.
