If necessary, adjust the length of the links by removing the cotter at the upperend of the links and turning them until the correct length is obtained.The link shortens when turned clockwise and extends when turnedanticlockwise.5. Check that both lifting links are of the same length after the adjustment.Correctly adjusted, the lifting links ensure that the rear linkage can be raised to itsuppermost position.
