e. Tighten four top holding screws.
£.
Check registration. 1£ necessary, repeat Steps
a through e.
4. If the vertical registration
is
off IllQre than a
few thousandths of an inch, the punch unit ad-
justment is not likely to be the cause. Investigate
some othe!-possible source of trouble such as:
a. Correct operation and timing of aligner sta-
tion.
b. Proper card feeding (loose feed roll belts,
etc.).
c. Worn or loose geneva studs and gears.
TIMING, MACHINES WITHOUT MAGNETIC PA EMITTER
Caution: Do not crank or start machine with timing
rod in place .
1. With punch unit installed in machine, insert tim-
ing rod 610077 through rear punch unit side
frame, through punch unit dial clearance hole,
and into camshaft· timing hole. Punch unit tim-
ing dial must now beat 0·.
2. Loosen split hub of punch unit drive pulley;
crank punch transport to O· . Geneva timing pin
must detent in drive disk.
3. Tighten split hub on drive pulley. Punch unit
is now timed to the transport and geneva.
4. With timing rod still in place, and PACB drive
pulley loose, turn PACB shaft until timing marks
on shaft hubs align with timing marks on PACB
housing (Figure 3-17).
5. Tighten split hub of PACB drive pulley. PACB
unit is now timed to punch unit.
6. Remove punch unit timing rod.
7. Crank machine and check punch unit index with
dynamic timer index. At 0·, on dynamic timer
index, punch index must read 0·, 120· or 240·.
TIMING, MACHINES WITH MAGNETIC PA EMITI'ER
Caution: Do not crank or start machine with timing
rod in place.
1. Before timing the punch unit to the punch trans-
port, the geneva unit must be in time. At 0° on
the machine index the geneva timing pin· must
detent in drive disc.
2. With the punch unit installed in machine, insert
timing rod 610007 through the timing holes in the
. emitter disc, rear punch unit frame, and punch
cam. shaft. If all three are not aligned it will be
necessary to adjust the emitter disc.
S. Loosen split hub of punch drive unit pulley;
crank punch transport toO e .. Geneva timing pin
must detent in drive
