(X) (shown in Figure
) between the front end
of the endshield and the header frame.
5.
Open the endshield and tighten nut (A).
6.
Loosen the bolts on catch (C), and adjust the catch as
needed to reposition the endshield.
7.
Ensure there is a snug fit between the top of the endshield
and the header frame, and that the endshield is fully
