Errate notice:

Please check both combination levers 3-7 for possible binding with the valve spindle yoke 1-16. Binding may be evident when turning over the drive wheels with the reversing lever 4-28 in full reverse or full forward. If the edge of the combination lever touches the valve spindle guide as seen in the 1st. picture below, remove the combination lever and file away the inside edge as shown in the 2nd. picture. Check both sides of your locomotive ! Sevier binding may cause premature wear of your valve gear mechanism.
