Introduction
1 The protouch Pro-10 system from Vinten comprises a Pro-10 pan and tilt head, a Pozi-Loc two-stage
tripod, an adjustable floor spreader and a soft case.
Description
Pro-10 pan and tilt head
2 The Pro-10 pan and tilt head (Fig 1.1) is designed to support the latest professional digital video
cameras, up to 10 kg (22 lb) in weight. It embodies fluid drag assemblies for pan and tilt motions with brakes
on each axis to lock the head in any position. An illuminated levelling bubble is fitted to the rear of the head
and a quick-release, adjustable slide plate is provided for camera mounting. A single fixed pan bar is supplied.
Balance
3 The balance spring in the Pro-10 pan and tilt head is set for an optimum payload of 7.5 kg (16.5 lb) at a
centre of gravity (C of G) height of 12.5 cm (4.9 in.), but the head will support a payload of up to 10 kg (22 lb).
Pan and tilt drag
4 Both the pan and tilt mechanisms incorporate fluid drag assemblies to ensure smooth movement of the
camera about these axes and are fitted with control knobs (8)(17) to adjust the drag setting.
Pan and tilt brakes
5Brakes(4)(11) on each axis are provided to lock the head in any position.
Illuminated levelling bubble
6 To enable the head to be levelled, an illuminated levelling bubble (10) is fitted to the rear of the head.
When the switch (13) is pressed, the bubble will be illuminated for approximately 15 seconds. The battery for
the illuminated bubble is contained in a battery compartment (16).

Camera mounting
7 The camera is attached to the head by means of a slide plate (14), which is provided with a spring-
loaded locating pin (5) and 1/4 in. (18) and 3/8 in. (1) screws. When not in use the screws are stowed in the
camera mounting platform (6). A clamp (7) is provided to hold the slide plate in position and a lock (2) prevents
its inadvertent removal from the head.
Pan bar
8 Pan bar mounting points (12) are located at the rear of the head, on either side of the camera mounting
platform. The pan bar is attached using a pan bar clamp, with angular adjustment available on the mount
serrations. A single fixed pan bar (3) is supplied. A second pan bar may be fitted.
Pozi-Loc tripod
9 The Pozi-Loc two-stage tripod (Fig 1.2) has aluminium legs and a 75 mm levelling bowl (19). It is fitted
with the highly-efficient Pozi-Loc leg clamps (20), which provide quick set-up and easy adjustment.
10 An optional ‘Spread-Loc’ mid-level spreader may be fitted to mounting points (25) on the legs.
Floor spreader
11 The floor spreader (Fig 1.2) increases rigidity of the tripod. Being flexible, the spreader compensates for
uneven ground, protects floors and carpets and prevents the tripod legs sinking into soft ground. It should be
used at all times.
12 Each arm is of the spreader is adjustable for length (22) and the tripod feet are secured by rubber
straps (24).

General
1 To identify components, please refer to Fig 1.1 and Fig 1.2.
Assembly
2 If not already done, assemble the system as follows:
Tripod and spreader
3 Lift the tripod out of the case using the finger holes just below the top clamps.
4 Release the leg tie strap (24) and spread the legs.
5 Secure the spreader to the tripod feet with the rubber straps (23).
6Adjust the operating height by undoing the leg clamps (20) and pulling the tripod up to the desired
height. Adjust the spreader (22) if necessary.
7 Tighten the clamps (20) until an audible click is heard and the knob is in the horizontal, locked position.
8 In adverse conditions secure the tripod using the tie-down hook (26), or suspend a weight from the
hook.
NOTE: Once assembled, keep the spreader attached to the tripod
WARNING!: Use care when the tripod is fully extended and the floor spreader is in the
closed position, as stability will be reduced.

Pan and tilt head
9 The Pro-10 pan and tilt head is supplied with a removable 75 mm ball mount. Adaptors are available
which enable the head to be installed on tripods or pedestals fitted with other mountings. These are listed
under ‘Optional Accessories’.
10 To install the head, remove the bowl clamp assembly (9) from the head, position the head on the tripod
and refit the bowl clamp assembly from below. Level the head with the aid of the level bubble (10) and tighten
the bowl clamp. The level bubble may be illuminated by pressing the switch (13). The light will extinguish after
approximately 15 seconds.
Mounting the camera
11 The balance spring in the Pro-10 pan and tilt head is set for an optimum payload of 7.5 kg (16.5 lb) at a
centre of gravity (C of G) height of 125 mm (4.9 in.), but the head will support a payload of up to 10 kg (22 lb).
The balance graph (Fig 2.1) shows the relationship between C of G height and payload for optimum
performance.
12 Remove the slide plate (14) from the head by releasing the slide plate clamp (7), pressing the slide lock
release (2) and pulling the plate out to the rear.
13 Install the required camera fixing screw (1) or (18) in the slide plate and retain with the rubber bung
(15). Stow the unused screw in the appropriate stowage (6) in the platform
14 Attach the slide plate to the camera or camera mounting plate under the approximate centre of the
camera's weight using the mounting screw and locating pin (5)(if appropriate).
15 Set the platform level and apply both the pan (11) and tilt brakes (4).
16 Push the slide plate and camera into the track in the platform, ensuring the slide lock release (2) snaps
into position.
17 Tighten the slide plate clamp (7).
Pan and tilt brakes
18 Brakes on each axis allow the head to be locked at any chosen position. The operating lever for the pan
brake (11) is at the rear of the head. The tilt brake (4) is operated by a lever on the left-hand side of the head.
19 To apply the brake, turn the lever fully clockwise. To release the brake, turn the lever counter--clockwise.
WARNING!: When the brakes are not in use, always turn the levers counter-clockwise.
DO NOT use the brakes to supplement drag.

Pan and tilt drag
20 Both the pan and tilt mechanisms incorporate a fluid drag system to ensure smooth movement of the
camera about these axes.
21 The tilt drag adjustment knob (8) is on the right -hand side of the head, the pan drag knob (17) is on the
top of the body.
22 To increase drag, turn the appropriate knob clockwise. To decrease drag, turn the knob counter-
clockwise.

NOTE: Reduce drag to a minimum when the head is out of use for long periods.

General
1 Protouch 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
2 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 ball mounting face of the head, the space between the tilting assembly and the base and the mounting
bowl of the tripod.
3 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.
Routine maintenance
4 During use, check the following:
4.1 Check the illumination of the level bubble. Replace battery if necessary.
4.2 Check the effectiveness of the pan brake. Reset as necessary.
4.3 Check the effectiveness of the camera slide plate clamp. Reset as necessary.
4.4 Check the effectiveness of the tripod leg clamps. Reset as necessary.
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.
