To couple the switch operator to the circuit-
switcher:
STEP 1� Manually operate the switch operator to bring
it to the same position (Open or Closed) as the
circuit-switcher. The switch operator position
indicator, seen through the observation window,
will show when the approximate Open or Closed
position has been attained. (The position indi -
cator for the circuit-switcher, located on the
output-shaft collar of the switch operator, will
be aligned later.)
STEP 2� Turn the manual operating handle slowly until
the position indexing drums are numerically
aligned to move the switch operator to the exact
position for coupling. See Figure 7.
STEP 3� Swing the selector handle upright and rotate
it counterclockwise to the Coupled position.
Lower the handle to engage the locking tab. The
selector handle is now in the Coupled position.
