Brake knob adjustment
8 The pan and tilt brakes are set during manufacture so that, when the brakes are fully applied, the knob
is vertical. As the brakes bed in during use it may be necessary to reset the knobs to this position.
9 The procedure for resetting the pan and tilt brake knobs is as follows (Fig 4.2):
9.1 Prise out the centre of the appropriate brake knob (5).
9.2 Turn the knob (2) clockwise to fully apply the brake.
9.3 Remove the screw (3) and washer (4) and pull the knob (2) off the shaft (1).
9.4 Refit the knob on the shaft in the vertical position.
9.5 Turn the knob fully counter-clockwise and ensure the brake is released.
9.6 Turn the knob clockwise and ensure that the brake is fully applied when the knob is vertical.
Adjust the position of the knob if necessary.
9.7 Secure the knob with the screw (3) and washer (4). Refit the knob centre (4), using Silcoset 153.
