disconnect primary power source and refer to cautionary statement or
nameplate before opening cover. Area must be free of flammable gases
and vapor before opening cover.
3. Perform visual check for undue heating evidenced by discoloration of
wires or other components, damage or worn parts or leakage evidenced
by water or corrosion in the interior.
4. Electrically check to make sure that all connections are clean and tight and
that contacts in the components make and break as required.
5. Mechanically check that all parts are properly assembled and operating
mechanisms move freely.
a. For more operator adjustment instructions, see Figure 4.
Fork Adjustment
1. Assemble operator into cover.
2. Measure distance from body flange to bottom toggle (Dimension A).
3. Measure distance from inside of cover to bottom of fork (Dimension B).
4. Adjust fork up or down so that (B - A - 0.12").
5. Move breaker toggle to "off" position and operator handle to "off"
position.
6. Close cover and check breaker operation.
7 . Adjust fork up or down to optimize breaker operation.
Stop Adjustment
1. Move operator to "on position. "
2. Put light pressure on handle in the "on" direction and hold in that position.
