ADJUSTMENT (Figure
36)
With the left
arm
of the T. lever in contact with the blank fUnction
lever extension, there should be some clearance, not more than
.008",
between
the right
ar.m
of the T lever and the universal function lever extension when
the
BLANK
combination is selected and the
main
shaft rotated until the blank
function lever is completely selected , stopping rotation at the point where the
fUnction lever bail roller just leaves the cam surface of the blank function
lever.
(On typing units equipped with blank printing-spacing cutout func tion
lever, it will be necessary to stop rotation of the main shaft at the point
where the function lever bail comes
to
rest on top of the blank p rinting
spacing cutout function lever.) To adjust, position the sem-recei ve mechanism
plate by means of its elongated mounting holes. When making this adjustment,
the intermediate lever should be clear of the blank function lever extension.
