Frame Tilt and Oscillation
7-4 Service Manual — Models 644B, 6K, 844C, 8K, 1044C, 10K
To level the frame, move the lever in the direction you want the ball in the
frame level indicator to move. Control is proportional: a small amount of
movement causes the frame to tilt slowly, while full movement of the
control causes faster frame movement.
