8. Recheck adjustments after several rotations of
punch unit camshaft. Setup bail height must be
gaged as closely as possible to drive unit side
frame. Side frames must be in contact with sur-
face on which gage is resting. Careful adherence
to these precautions and to the procedure out-
lined will result in bail parallelism within .003".

ure 3-32 when performing Steps 2 through 8.
