SPACED BETWEEN
SEPARATORS.
Special care should be taken that all dirt is cleaned from between the
segments of the feed roll separator. The grooved dilecto roll is ad-
justed horizontally by means of the brush roll locating collar so that
the brushes are in the center of the grooves. Use the brush bending
tool on individual brushes. Revolve the roll to make sure brushes are
free all the way around.
(f) BRUSH TRACKING. Change by shimming the brush assembly
holding brackets located on the side castings.
(g)
BRUSH TIMING. The brushes are timed to the holes in the card
so they will make a t least 11/20 before every selecting impulse, and
break not earlier than
11/~"
after each selecting impulse breaks. The
make and break timing af the brushes should be checked for each
selecting and zoning impulse. The correct timing is obtained by
loosening the holder clamping screws and moving the holder left or
right in the assembly. Make sure that the clamping screws are
tightened after the correct timing is obtained. The brushes should
never have a duration of longer than 2" before and after the make
and break of the selection circuit breakers, or
a total of 7" duration
a t selection time. See information on "CB's" under Base for this
machine.

Cleaning
Type bars should be cleaned of all dirt and old ink. The face on the type
tails should be cleaned with a stiff brush taking care to clean out all accumu-
lated material from the center of the letters. An alternate cleaning method
would be to use plastic type cleaner, part 450528.

Inspection
1.
Type
U n i t .
Before removing type unit from machine, operate the machine
manually under power without cards and observe the operation of the
type bars. They may best be viewed from the left end of the machine
under the magnet unit. Check the releasing time and the restoring of the
bars. Any bars in which the friction slide spring tension is insufficient will
have a tendency to fall down during the restoring part of the cycle. Note
the number of any bars not operating correctly and correct when unit is
removed.
