2. Clean the ball with a soft lint-free cloth, and then blow carefully into the ball-cage to
dislodge dust and lint.
3. Look for a build-up of dirt on the metal rollers. If dirty, clean the rollers using a cotton
swab moistened lightly with isopropyl-rubbing alcohol.
4. Make sure that fluff from the swab is not left on the rollers.
5. Replace the ball and retainer ring. Be sure the retainer ring is not inserted reversely.
