the appropriate lever up and back and released by pushing the lever forwards. The brakes should be applied
whenever the camera is left unattended.

adjusted by a knob (17) mounted on the face of the tilt drag housing on the left-hand side of the head. Turn the
knobs clockwise to increase drag and counter-clockwise to decrease drag.
