Initial Seat

• Using the 45° cutter, descale and clean up the seat. Rotate the cutter one or two turns.

• Measure the valve seat width ® after every cut.

Cut only the minimum amount necessary from the seat to prevent the possibility of the valve stem becoming too close to the rocker arm for correct valve contact angle.
