(Figure 20). One tab lever assembly serves all pitch
Model C Typewriters. Tab stops may be set at every
space on standard pitch machines without interfering
with the operation. Tabulation is possible to each
set tab stop on the 6% pitch machine and to every
second tab stoP. when consecutive stops are set, on
all other standard pitches.
The tab latch is mounted atop the rear rail with an
adjustable eccentric and works against a lower ex-
tension of the tab lever (Figure <17). The tab-check
lever works against a lug on the tab latch to effect
tab lever unlatching.
Removal
TAB LEVER

4. Disconnect the tab-lever spring, tab-latch spring,
and the decelerator-bellcrank link.
5. Remove the tab-lever-pivot stud.
6. Remove the tab lever by lifting it up and toward
the rear.
Reassembly may be accomplished by reversing the
above procedure. Avoid over-tightening the self-lock-
ing nut on the tab-lever-pivot stud as this may cause
binding of the tab lever.
