NOTE:
The design of the pan and tilt brake knobs was improved at Serial No. 00109. The improved
knobs, which are easier to remove and install, are interchangeable with the earlier knobs.
The pan and tilt brake knobs are set during manufacture so that the brakes are fully
applied before the knobs reach their upper stops. As the brakes bed in during use it may
be necessary to reset the knobs.
The procedure shown is for the tilt brake knob.The pan brake is adjusted in a similar
fashion
