8. Insert a card lengthwise between rolls on one end
of first intermittent feed roll shaft. Insert another
card lengthwise between other rolls of first inter-
mittent feed roll.
9. Check that' each card is free at 353', and is
gripped tightly at 357'. This indicates first inter-
mittent feed roll is in time.
SECOND INTERMIT1ENT AND SECOND STEPPED FEED ROLLS
TIMING CHECK
1. Trip clutch at 300'
~nd,
with clutch engaged
(315' ), crank machine to 290'.
2. Insert card between each of the pairs of rolls on
second intermittent feed roll shaft. This card can
be inserted from punch check brush station.
3. While turning feed backward, card should be
free at 290

This.
indicates second intermittent roll is in time.
4. At 285', a strip of card can pass between the sec-
ond stepped roll and its upper pressure rolls.
5. Crank machine to 292' and card should be free.
Card should be gripped tightly by 295'. This as-
sures that the second stepped roll is in time.

FORWARD AND SIDE ALIGNERS TIMING CHECK
When checking these timings, punch unit must be re-
moved. The first stepped feed roll must be i~ time be-
fore checking the aligners. See Figure 3-26.
1. Latch the die into position to serve as card guide.
NOTE:
Die card guide gage 610094 replaces the
die in machines containing redesigned die and
stripper, P /N 601981.
2. Insert timing gage 608183 (Figure
3~27).
3. Pivot hopper up and place cards in it. Trip clutch
at 300' and crank machine until clutch engages
( 315' ). Feed cards manually for two card cycles.
4. Continue cranking machine and check that card
finishes forward aligning to within .005" of for-
ward aligner timing marks on gage at 351' (F.ig-
ure 3-28). This times forward aligner correctly.
NOTE:
The following step is necessary on ma-
chines with adjustable left side aligner.
5. With machine still at 351', cheC!t. that left side
aligner surface is against card aM 37/64" from
inside of left side frame. Check that right side
aligner is just touching card at 351'.
NOTE:
The following step is necessary on ma-
chines with a fixed left side-aligner block.
