is suspected. Adjustment is to be accomplished
as follows:
t
1. Loosen both socket-head shoulder screws
located on the pivots of the cartridge receiver
so that receiver is free to move slightly.
2. With the front of the cartridge receiver located
in its preferred position, tighten the two
shoulder screws until they just contact surfaces
of the cartridge receiver pivots. This will
secure the adjustment.
4. 18.3 Cartridge In Place Switch Adjustment
NOTE: The cartridge in place switch cannot be
adjusted; however, its function may be checked by
standing in front of machine while using the follow-
ing procedure: (A quick check of the switch opera-
tion can be accomplished by step 4.)
1. Insert cartridge in receiver and observe the
action of the cartridge in place switch as the
receiver handle is raised.
2. Verify that switch transfers when cartridge is
fully seated on its rest pins. Ensure that the
cartridge is not touching the switch lever
anywhere except on its operating end.

3. Use five mM cards as shims between the
shoulder of the closest rest pin and the bottom
of the cartridge. Verify that the switch trans-
fers before cartridge is fully seated on the rest
pin.
4. With the cartridge receiver handle locked in
place by the interlock latch to secure the cart-
ridge in place, move the handle end of the
cartridge up and down with moderate force to
see if the transferred condition of the switch is
affected. The switch must remain transferred.

4. 19. 1 Handle and Interlock Adjustment
(Figure 4-10)*
NOTE: The cartridge receiver adjustments (section
4. 18.2) must be completed prior to attempting an
adjustment of the cartridge interlocks. Two station-
ary posts located on the base plate prevent lowering
of the cartridge before it is fully inserted into the
receiver. The receiver interlock magnet must be
removed to accomplish interlock adjustments for
the Handle Stop Screw and latch screw clearance.
Handle Stop Screw Adjustment
The. handle stop screw must be adjusted so that,when
a cartridge is in place, the handle risers will be
parallel with the stationary guide posts within
0.30
(±O.
015) inch. Adjustment of the handle stop
screw is accomplished as follows:
1. Remove the interlock handle and bracket
assembly.
a. Remove the two flat-head screws which
secure bracket to base plate.
b. Remove wire connections at pins 3 and 4
from terminal block TB6. Mark each pin
location to facilitate reassembly.
2. Install CE cartridge in machine.
3. Loosen handle stop screw locknut and adjust the
handle stop screw so that handle risers are
parallel with the stationary safety posts within
0.030 (±0.05) inch.
4. Tighten the locknut to secure the final adjustment
made on the handle stop screw.
