Step 6
Verify that the actuating push rod fully rests to its
original position by observing the grease wipe on
the actuating push rod at the eyebolt.
(Push rod shown with the circuit breaker rolled
off the adjustment tool.)
No grease wipe should be shown! This confirms
that the rod is at its reset position.
Attention: Grease wipe visible after removal of ad-
justment tool indicates that the actuating push rod
has not reset!
(Push rod shown with the circuit breaker rolled
on to the 0.80 inch step of the adjustment tool.)
