ADJUSTMENT - Continued
It may be necessary to upset the actuator lever to cause oscillation.
Turn the S1 setting clockwise slowly until the actuator lever (Figure 4, Item 1) becomes unstable and
Turn the S1 potentiometers slowly counterclockwise until the actuator lever (Figure 4, Item 1) is stable.
Disturb the actuator lever (Figure 4, Item 1) and verify that it oscillates three to five times, getting
slower and slower.
