The anvil is an important component in maintaining a consistent machine
performance. Inspect it through an open rotor housing. A measure of the
wear is how sharp the edge is. If it has become seriously rounded then it is
appropriate to change it.
Turning or replacing the anvil should be carried out by a Timberwolf dealer.
