Installation Procedure
1. Remove shipping braces, tape, plastic cover from
relay gate and blocks under feed shock mounts.
2. If lower magazine throat has two flat springs skip
to Step 3. If the lower magazine throat has a
mirror finish:
a. Remove front and rear covers from sides of
hopper casting.
b. Loosen screw at bottom of each flat spring and
lift out file feed filler. See Figure
I-I.
c. Remove clip from stud on each support plate.
d. Remove tape, holding pivot pins in upper
magazine. Move pins flush with upper maga-
zine slides.
e. Hold upper magazine in vertical position; set
into lower magazine so pivot pins are under
fingers of lower magazine.
f. Place upper magazine struts on studs. Replace
clips.
g. Slide pivot pins into support plate holes.
h. Tighten screws.
i.
Replace file feed filler and covers.
j. Go on to Step 4.
3. If the lower magazine throat has two flat springs:
a. Remove two covers from sides of hopper cast-
ing.
b. Loosen screw at bottom of each flat spring and
lift out file feed filler. See Figure
I-I.
c. Remove clip from stud on each support plate.
d. Hook magazine struts over studs and replace
clips.
e. A split shaft, held by a set screw, is located
just above file feed drive shaft. Slip both
halves of shaft to center, inside of castiI).g.
f. Put upper magazine in place and slide both
halves of shaft from center so they hold maga-
zine in place. Ends of split shaft should be
flush with end of magazine holes.
g. Tighten set screw to secure split shaft.

h. Replace file feed filler.
i. Replace two covers.
4. Examine all relays (without removing) for dis-
placed armatures.
.5.
Trip clutches and crank machine by hand, check-
ing for binding conditions in feeds or card trans-
port.
6. Install shroud 609386 on cable junction box.
7.
After installing main line cord through bottom of
machine, check that cable clamp is fastened se-
curely to bottom plate of machine.
8. Check power supply voltages at CE Panel.
9. Check covers for proper fit and appearance.
10. Check operation of file feed. Adjust file feed delay
resistor on relay gate so approximately a two-inch
stack of cards enters hopper before feeding be-
gins.
11. Run test decks to verify machine operation.
