Introduction
The Vision Pozi-Loc range includes single- and two-stage tripods with either aluminium or carbon fibre legs, fitted with 75 mm, 100 mm or 150 mm levelling bowls (See table on page 4). All are fitted with the highly-efficient Pozi-Loc leg clamp, which provides quick set-up and easy adjustment. The tripods are designed for use with Vinten floor spreaders and dollies. An optional mid-level spreader may be used. Low-level `baby-legs’ versions are also available, fitted with a simple cleat rope spreader.

Operation

NOTE:

The following procedures refer to a two-stage tripod fitted with a Vision head and a floor spreader. The procedure for single-stage tripods is essentially similar. When using a two-stage tripod the bottom stages should be fully extended or fully retracted, unless conditions such as split levels prevent this.

Lift the complete tripod and head out of the case using the finger holes just below the top clamps.

NOTE: Keep the spreader attached to the tripod

Set the pan bar.
Release the leg tie strap (5).
Still holding the finger holes, open out the legs. Gentle foot or hand pressure on the spreader (3) will ensure that the legs are fully spread.

NOTE:

Always use the spreader where possible as this increases rigidity of the tripod. Being flexible, the spreader compensates for uneven ground. It can be removed and a dolly fitted. At the fullest extension of the spreader and with all legs fully retracted, the tripod can be used at its lowest operating height. Although the tripod can be set up lower than this without the spreader, it is NOT recommended as the tripod geometry becomes unstable

Adjust the operating height by undoing the leg clamps (2) and pulling the tripod up to the desired height. Adjust the spreader (4) if necessary. Level the head using the level bubble.
Tighten the clamps (2) until an audible click is heard and the knob is in the horizontal, locked position.
In the case of a `baby-legs’ tripod, tighten the cleat rope spreader (8).

NOTE: An optional, conventional floor spreader (3379-3) is available for the `baby-legs’ tripods.

WARNING! It is possible to set the tripod legs so that the centre-of-gravity of the tilted payload falls outside the footprint of the tripod, leading to instability. Use a mid-level or floor spreader to ensure that the tripod legs are spread sufficiently so that the centre-of-gravity of the tilted payload remains within the footprint of the tripod. Secure the tripod with the tie-down hook (7) or hang a suitable weight from the hook.

NOTE:

The Vision spreader protects floors and carpets as well as preventing the tripod legs sinking into soft ground and should be used at all times. If the floor spreader cannot be used, use Vision carpet feet and a `Spread-Loc’ mid-level spreader.

Optional equipment
‘Spread-Loc’ mid-level spreader
To install the spreader: Grip the ends of each spreader arm in turn between thumb and fore-finger and press in the attachment release buttons (9). Push the arm into the tripod attachment (6) until the release engages. Fit the carpet feet (10). To remove the spreader, press in the attachment release buttons (9) and free each arm in turn.

Carrying strap
A carrying strap is available as an optional accessory and is installed as follows: 150 mm bowl tripods On the underside of the tripod bowl, identify the M6 tapped hole (18). Position the bowl strap anchor (17) on the underside of the tripod bowl, ensuring it is correctly oriented. Using Loctite 221, secure the bowl strap anchor with the 25 mm M6 screw (16) supplied with the strap. On the lower moulding of the corresponding leg, drive in the ‘knock-out’ (15) using a suitable tool. If possible, remove the blank from inside the moulding to prevent subsequent rattle. Push a blind captive nut (14) into the hole in the lower moulding. Using a suitable M5 screw, fully compress the blind captive nut. Remove the M5 screw. Install a washer (13) on the lower strap anchor (12) and screw into the captive nut (14). Ensure that the hole in the strap anchor is oriented so that the karabiner (11.1) can be attached Using the karabiners (11.1), clip the strap (11) to the strap anchors and adjust to length. 75 mm and 100 mm bowl tripods On the lower moulding of the leg with the strap (5), drive in the ‘knock-out’ (15) using a suitable tool. If possible, remove the blank from inside the moulding to prevent subsequent rattle. Push a blind captive nut (14) into the hole in the lower moulding. Using a suitable M5 screw, fully compress the blind captive nut. Remove the M5 screw. Install a washer (13) on the lower strap anchor (12) and screw into the captive nut (14). Ensure that the hole in the strap anchor is oriented so that the karabiner (11.1) can be attached On the underside of the tripod bowl, remove and discard the screw (16) securing the corresponding leg clamp (20). Do not remove the washer (19). Position the bowl strap anchor (17) on the leg clamp, ensuring it is correctly oriented. Using Loctite 221, secure the bowl strap anchor with the 25 mm M6 screw (16) supplied with the strap. Tighten screw to a torque of 4.5 Nm (40 lbf in.). Using the karabiners (11.1), clip the strap (11) to the strap anchors and adjust to length.

Servicing
General
Vision products are robustly made to high engineering standards and little attention is required to maintain serviceability save regular cleaning. Attention to the following points will ensure a long and useful service life with minimum need for repair.
Cleaning
During indoor use, the only cleaning required should be a regular wipe over with a lint-free cloth. Dirt accumulated during storage may be removed using a semi-stiff brush. Particular attention should be paid to the mounting bowl of the tripod. All tripod, spreader and dolly parts are weatherproof. However, use out-of-doors under adverse conditions will require special attention. Salt spray should be washed off with fresh water at the earliest opportunity. Sand and dirt acts as an abrasive and should be removed using a semi-stiff brush or vacuum cleaner.
NOTE: Use only detergent-based cleaners. DO NOT use solvent- or oil-based cleaners, abrasives or wire brushes to remove accumulations of dirt, as these damage the protective surfaces.
Routine checks
During normal use, check the effectiveness of the leg clamps and adjust as necessary.
Adjusting `Pozi-Loc’ leg clamps
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 clamps (2). 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 Top clamp
Adjust a top clamp as follows: Turn the clamp knob (21) to the vertical, `off’ position Remove screw (23). Using a suitable peg spanner, back off the threaded insert (22) 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 (22) until the clamp begins to grip. If not aligned, back off the threaded insert (22) until a slot aligns with the hole for screw (23). Carbon fibre tripods (black legs) – back off the threaded insert (22) two slots. Aluminium tripods (grey legs) – back off the threaded insert (22) three slots Install screw (23) to secure the threaded insert (22).

Bottom clamp
Adjust a bottom clamp as follows: Tighten the clamp (26) until an audible click is heard and the knob is in the locked position (Position 1). Using a suitable instrument, such as a flat-bladed screwdriver, carefully remove the knob cap (29). Remove the retaining screw (28) and washer (27), and pull off the clamp knob (26). Examine the shaft (24). If there is an identifying groove (24.1) on the shaft, proceed as follows. Otherwise, consult Vision Pozi-Loc Tripods – Spares and Repairs (Publication Part No. 3770-9) or contact your local Vinten dealer. Replace the clamp knob (26) and turn it to Position 2. Using a 2.5 mm hexagonal wrench, slacken the grubscrew (24) until the leg is free to move under its own weight.

With the knob still in Position 2, slide the leg in and out and gradually tighten the grubscrew (24) until the clamp begins to grip. Back off the grubscrew (24) by a quarter-turn (90°). Secure the clamp knob (26) with the washer (27) and retaining screw (28). Refit the knob cap (29).
