OPERATION
Adjusting Endshields
Plastic endshields m ay expand or contract when subjected to large temperature changes. The position of the top
pin and lower catch can be adjusted to compensate for dimensional changes.
To adju st the end shield, perform the follow ing:
1. Check gap ‘X’ between the front end of shield and
header frame and compare to chart.

If adjustments are required, proceed as follows:
2. Open endshield. Refer to Opening Endshields, page
33.
3. From inside endsheet, loosen nut (A) on pin (B) with a
3/4 in. (19 mm) socket.
4. Close endshield and adjust position to achieve
the gap ‘X’ between the front end of shield and
header frame.
5. Open endshield and tighten nut (A).
6. To achieve a snug fit between top of shield and header
frame and to ensure that endshield is fully engaged on
pin (B), loosen bolts on catch (C) and adjust catch as
required to reposition shield.
7. Tighten bolts o n catch (C).
8. Close endshield. Refer to Closing Endshields, page
34.
