Drag Knob Adjustment - Vinten Vision blue3 Operator's Manual

Using the flat-blade screwdriver or similar tool tighten the securing screw [19]. Do not
overtighten.
To test the brake, turn the lever clockwise and ensure that the brake is fully applied
before the upper stop is reached. Then turn the lever fully counter-clockwise and ensure
that the brake is fully released before the lower stop is reached. Re-adjust the position
of the lever as necessary.

Drag knob adjustment

(Fig. 8)
The pan and tilt drag control knobs ([13], [5]) are set so that drag begins to be felt in the arrow
area on the indicator [13.2].
To reset the drag knobs:
Release the pan and tilt brakes.
Turn the drag control knob [13], until the grub screw [13.1] is accessible. Using an Allen
key slacken the grub screw by six turns.
Hold the indicator [13.2] stationary and slowly rotate the drag knob [13] 18 degrees to
the left. Eighteen degrees is two clicks of the detent mechanism or half the pitch of the
control knob lobes.
Using an Allen key, carefully tighten the grub screw [13.1], adjusting the position of the
control knob as necessary, so that the grub screw seats correctly in a slot in the indicator
and can be fully tightened.
To test the adjustment, decrease drag to zero. Then increase drag and ensure that drag
begins to be felt in the arrow area on the indicator [13.2] and that '9' on the indicator can
be reached. Re-adjust the drag control until this can be achieved.
