Form (in circled area) the actuating wire (left or
right) so that it contacts the actuating arm near
the right ang Ie bend (Fig. 174).
With the tab interposer released and. the T ab/Sp/BS
cam on its high point
r
position the mounting brack-
et (front to rear) so that the actuating arm overiaps
(.040 11
minimum) the actuating wire (Fig.
174).
This insures that the actuating wire does not get a-
bove the actuati ng arm.

As the tab torque bar restores, posi ti on the mounti ng

wire travels

fers (Fig. 175).
This is done to insure that mach-
ine vibration does not cause the contact to transfer.

MARGIN CONTROL MECHANISM
Margin Rack Overbank Guide - With the carrier resting
at the left hand margin, adjust the overbank guide (Fig.
176)
left or right on the margin rack to obtain
.00111
to
0005 11
clearance between the margin stop and the margin
stop latch on fhe carrier when the margin rack is in its
rest position (Fig.
176).
When observing this clearance
remove the floating action of the margin stop latch by
pulling the stop latch to the right with a spring hook.

Margin Rack Overbank Guide
The adjustment insures that the left margin stop wi II set
accurately when the stop is slid to the right against the
margin stop latch on the carrier.
NOTE:
Machines equipped with an old style margin
rack use an eccentric plate mounted on the right end of
the marg in rack to contro I the rest posi ti on of the rack.
Use the same procedure i ndi cated above to obta i n the
.00111
to
.005 11
clearance between the margin stop and
the stop latch on the carri er.

With all parts at rest, loosen the fluted screw
in the margin release lever and rotate the mar-
