Installation & Adjustment Procedures
Operating Mechanism Adjustment
If a motor operator Is used, DO NOT USE ELECTRICAL OPERATION until the following
adjustments are completed.
NOTE : The setting of the adjustable arm on the Operating Mechanism Drawing is a calculated
dimension. To adjust precisely:
1) The adjustable arm should travel at least 180 degrees from toggle closed to toggle open.
This adjustment can be done in a neutral position where the adjustable arm is perpendicular
to the clevis. (Exceptions may occur. Refer to the Operating Mechanism Drawing.) Manually
test operate.
2) If the switch does not fully open, the radius of the arm is too short. To correct:
a. Check first to see that nothing has slipped.
b. Return the switch to the closed position.
c. Loosen the adjustable arm and clevis bolts as shown below.
d. Lengthen the radius of the adjustable arm in ¼ inch increments or less and allow the
clevis to reposition itself the same distance (shorten-ing the pipe).
e. Test operate again and adjust as necessary.

3) If the switch is fully open before the control handle reaches the open position, the radius of
the adjustable arm is too long. To correct:
a. Check to see that nothing has slipped.
b. Return the switch to the closed position.
c. Loosen the adjustable arm and clevis bolts as shown above.
d. Shorten the radius of the adjustable arm about 114 inch and allow the clevis to
reposition itself (lengthen-ing the pipe).
e. Test operate again and adjust as necessary.
Note : All poles of the fully adjusted switch should operate simultaneously. Slight adjustment of the
interphase clevises may be necessary to coordinate all three poles.
4) When the switch is completely adjusted, securely tighten all bolts, and tighten all set screws
until the pipe walls are pierced. (For heavy wall pipe, drill the set screw holes, using the
threaded drill guides sup-plied and a 1/4" drill.)
