Camera slide plate knob adjustment
11 To prevent interference with the payload, the camera slide plate knob (7) should be at or below the
horizontal when applied.
12 To adjust the camera slide plate knob (Fig 4.2):
12.1 Remove the securing screw (7.1) and pull the knob (7) off the shaft (7.2).
12.2 Turn the shaft (7.2) clockwise until the slide plate clamp is fully applied.
12.3 Install the knob (7) on the shaft (7.2) approximately at or below the horizontal.
12.4 Turn the knob fully counter-clockwise and ensure the slide plate clamp is released before the
stop is reached. Turn the knob clockwise and ensure the clamp is applied before the knob reaches the
horizontal.
12.5 Readjust as necessary and secure the knob with the screw (7.1).
‘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 (20) to the vertical, ‘off’ position
14.2 Remove screw (20.1). Using a suitable peg spanner, back off the threaded insert (20.2) slot by
slot until the leg is free to move under its own weight.
14.3 While sliding the leg in and out, gradually tighten the threaded insert (20.2) until the clamp begins
to grip.
14.4 If not aligned, back off the threaded insert (20.2) until a slot aligns with the hole for screw (20.1).
14.5 Back off the threaded insert (20.2) a further three slots
14.6 Install screw (20.1) to secure the threaded insert (20.2).
