Pan and tilt brakes
13
Friction brakes on each axis allow the head to be locked at any chosen position. The operating levers
for the pan brake
and tilt brake
are fitted at the left-hand side of the head.

To apply the brake, turn the lever fully clockwise. To release the brake, turn the lever fully counter-
clockwise.
Pan and tilt drag
15
Both the pan and tilt mechanisms incorporate the Vinten lubricated friction (LF) system to ensure
smooth movement of the camera about these axes and are fitted with control knobs to adjust the drag setting.
16
Both drag knobs are provided with illuminated scales, graduated from 0 to 9. To illuminate the scales,
press the switch
. The lamps will extinguish after 15 seconds.
17
The tilt drag adjustment knob
is on the right-hand side of the head, the pan drag knob
is on the
rear of the head. The whip-pan facility is unaffected by the pan drag setting.
18
To increase drag, turn the knob clockwise, towards a higher graduation. To decrease drag, turn the
knob anti-clockwise, towards a lower graduation.
NOTE:
Maximum tilt angle is less than 90° for heavy payloads with high C of G - see balance
graph.
