POSITIVE STOP SCREW MICRO ADJUSTMENT (SA-115)
For application refer to your instruction manual drawing no. IM-49-1-A.
The Micro-Switch within the Positive Stop Screw knob Is set at the
factory to operate approximately .010 before the RAm reaches the end
of it's stroke. This is accomplished by means of the Actuator Rod,
located inside the Positive Stop Screw Sleeve, extending approximately
1/16 of an inch beyond theStop Button. As the Ram moves forward, the
Actuator Rod is depressed by the Stop ~ Button (located in the Ram
Bed) starting the Dwell Timer

terminals.
B. Thread the Dial Micrometer (available from Glebar part #TLA-438)
clockwise on the end of the Positive Srop Screw Shaft until
it bottoms out. The circuit should close reading zero OHM's.
C. Turn counter clockwise until the circuit opens.
D. Carefully turn the dial clockwise again, stop when the circuit
just closes.
E. Mark the positive Stop Screw with a reference line next to
the zero line, near the base of the Dlal Micrometer.
F. Turn the dial clockwise, counting the number of lines, (.001
per div.) until it bottoms out.
The result should be approximately .010, if not, proceed as follows:
