Tilt brake knob adjustment
11 Because its movement is restricted, the tilt drag knob (4) may also require adjustment after prolonged
use:
12 To adjust the tilt brake knob:
12.1 Slide off the rubber tilt drag knob (3) as shown in (Fig 4.2).
12.2 Loosen the drag clamp grubscrew (3.2) and remove the drag knob actuator (3.1) from the drag
shaft (3.3).
12.3 Loosen the brake clamp grubscrew (4.1) and remove the tilt brake knob (4) from the brake shaft
(4.2).
12.4 Turn the brake shaft (4.2) counterclockwise until the tilt brake is fully applied.
12.5 Install the knob (4) on the brake shaft (4.2) with the lever approximately 30° - 45° past vertical,
pointing downward toward the rear of the head, or as suitable to the operator.
12.6 Turn the knob fully clockwise and ensure that the brake is released. Turn the knob
counterclockwise and ensure the brake is applied at a suitable position before the knob interferes with
other head controls.
12.7 Readjust as necessary and secure the knob with the clamp grubscrew (4.1).
12.8 Refit the drag knob actuator (3.1) onto the drag shaft (3.3) and secure with the clamp grubscrew
(3.2).
12.9 Push the rubber drag knob (3) back onto the actuator (3.1).
‘Pozi-Loc’ tripod leg clamp adjustment
13 Bedding-in occurs with ‘Pozi-Loc’ leg clamps, which may necessitate resetting the clamp. Check the
effectiveness of each leg clamp as follows:
13.1 Extend all three tripod legs fully and apply the clamp(s).
13.2 Position each leg in turn vertically on a set of weighing scales.
13.3 Gradually apply body weight to the leg until either or both clamps begin to slip. Note the reading
on the scales at which this occurs.
13.4 A reading of less than 35 kg (77 lb) will necessitate adjustment.
Top clamp
14 Adjust the top clamp as follows (Fig 4.3):
14.1 Turn the clamp knob (21) to the vertical, ‘off’ position
14.2 Remove screw (21.1). Using a suitable peg spanner, back off the threaded insert (21.2) slot by
slot until the leg is free to move under its own weight.
