II. Balance Arm

The adjustment of the balance arm (40-31) is to achieve proper balance in the differential system between positive and negative operations.

To adjust the balance arm do the following:

1. Depress and half cycle the letter "J" - observe the detenting, see where detent contacts element on negative slope.

2. Adjust the stop screw (72-42) for the negative 5 bail so the "J" detents like the "O".
