‘Pozi-Loc’ tripod leg clamp adjustment
Bedding-in occurs with ‘Pozi-Loc’ leg clamps, which may necessitate resetting the clamp. Check
the effectiveness of each leg clamp as follows:
Extend all three tripod legs fully and apply the clamp(s).
Position each leg in turn vertically on a set of weighing scales.
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.
A reading of less than 35 kg (77 lb) will necessitate adjustment.
Top clamp
Adjust a top clamp as follows:
Turn the clamp knob (20) to the vertical, ‘off’ position
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.
While sliding the leg in and out, gradually tighten the threaded insert (20.2) until the clamp
begins to grip.
If not aligned, back off the threaded insert (20.2) until a slot aligns with the hole for screw
(20.1) .
Back off the threaded insert (20.2) a further three slots.
Install screw (20.1) to secure the threaded insert (20.2) .
