spins

My random orbit sander spins out of control (very fast) when not under load.

Hi Chris,

It sounds like the brake ring on your sander has gone out. The brake ring acts like a clutch to control the pad speed when there is no load. When it wears out your sander will spin out of control. The brake ring is part # 421866-9 and is available from http://www.ereplacementparts.com.

Good luck with your repair!
