TEETH AND TOOTH TIP WEAR LIMITS
NOTE: Do not wait for teeth or tooth tips to be completely worn through before changing them. IMPORTANT: Never try to work with a missing tooth tip or a tooth tip which is worn through. The adaptor could be seriously damaged.
PH08307 The degree to which teeth or tooth tips are worn can be assessed visually. It is possible to extend the life of teeth or tooth tips which are wearing unevenly, in a non-symmetrical fashion. Interchange and turn over the teeth regularly. Turn over the locking pin too.
