Abnormal drive-contact noise occurs while the pad turns

A repeatable grinding or scraping sound comes from beneath the tool while the pad turns.

• Pad or dust skirt is rubbing
• Belt is damaged or misrouted
• Drive bearing or eccentric is failing
• Debris entered the pad/drive clearance

1. The drive turns quietly after an external rub is corrected, or the tool is removed from service.

1. Set O, remove the battery immediately, and do not repeat the noise under load.
2. Remove the disc and inspect pad, skirt, four screws, and accessible clearance for rubbing debris.
3. - Rotate the pad by hand
4. - Correct only a proven external rub
