Settings: Sweep length — handwheel drives the motor to one edge of the sweep; the arc width is derived from that position.

ROCK — Motor oscillates slowly over a small arc. Turn the handwheel to shift the center of oscillation without stopping the movement.
Settings: 1. Width — handwheel drives the motor to one edge of the arc; width is derived from that position. 2. Speed — oscillation speed.
