3. Check the jaws and teeth for wear. Replace if necessary. Any type of hardfacing
welding on the teeth of the jaws is not recommended as they are made of die-
cast, wear-resistant material. Hardfacing welding on the teeth would alter their
special shape, reducing the ability to penetrate concrete as well as productivity.
See “Replacing teeth” on page 52.
4. Check the grease nipples.
