SWITCH ADJUSTMENTS
Adjustments to the closing of the switches can be attained
by inserting a 0.050 Allen screw, turning the screw clockwise
to decrease the amount of movement required to close the
switch and counterclockwise to increase the amount of
movement required to close the switch. All adjustments of
the switches and readings of the volt-ohm meter are to be
made with the treadle being depressed (downward stroke).
Never attempt to adjust the switches on the release of the
treadle application (upward stroke).

the red lead to pin #4 or D. At this time, the meter will
have a maximum reading (open circuit). Slowly depress
the treadle until you can feel resistance to the movement
being applied. At the point of the end of the free travel of
the treadle, approximately 1/2" movement at the end of
the treadle, switch #2 should close and the volt-ohm will
respond with a reading of near 0. If an adjustment to this
switch is required, follow the instructions under the
