- pull out the counterbalance lever "N" (fig. 7B)
- turn the counter-balance lever "N" anti-clockwise until it reaches the minimum counterbalance weight,
keeping the head in a level position
To be sure that the head is completely fluidity-free, proceed as follows :
- unlock the tilt brake "Q"
- turn the tilt drag knob "P" anti-clockwise all the way
- loosen the lever "M" (fig. 7B) and keep it pressed down as you slide the camcorder until you reach
the balance point in which the head remains level under the camcorder load.
- with the camcorder at the balance point, lock plate "L" in position by locking knob "M" as shown in
figure 7C: the arrow must remain inside the LOCK rectangle.
NOTE: once the correct position has been found, it can be memorized by taking note of plate "L"'s
position on the graded scale "R" (fig. 7C).
COUNTERBALANCING THE CAMERA ON THE HEAD
The head features a nitrogen piston counterbalance system for counterbalancing the weight of your
equipment. To set it up correctly, make sure that the piston is positioned in the appropriate payload position.
Please proceed as follows:
1. unlock the tilt brake "Q" (fig. 8A)
2. turn the tilt drag knob "P" anti-clockwise all the way to be sure that the head is completely
fluidity-free (fig. 8B)
3. pull out the counterbalance lever "N" (fig. 8B)
4. turn counter-balance lever "N" anti-clockwise until it reaches the minimum counterbalance weight
5. slightly turn counter-balance lever "N" clockwise keeping the head in a level position (fig 8D)
With one hand on the pan bar, tilt the camcorder forwards and backwards (fig. 8E):
• If the camera also moves forward when tilting forward, the head has not been properly counterbalanced.
To fix this, turn lever "N" clockwise again, keeping the head in a level position to increase piston
power.
• If the camera moves forward into a level position when tilting backwards, the piston is too powerful. To
fix this, turn lever "N" anticlockwise again, keeping the head in a level position to decrease piston
power.
If the camera stays locked into place for each tilt angle, counterbalance has been correctly set.
N.B. The "N" lever modifies the balanced load. Please note that it is a control system, not a lock. Once
the fluid movement's limit switch positions AA (Maximum weight) and BB (Minimum weight) have
been reached (see figure 8C), do not force the lever's rotation. Approximately 11 complete rotations
of counterbalance lever "N" are required to move from position "BB", equivalent to a counterbalanced
load of 0 kg to position "AA", equivalent to a balanced load of 8kg @55 c.o.g.
A higher number of rotations may compromise the counterbalance system's performance or,
in the worst cases, the product's safety.
REMOVING THE CAMCORDER FROM THE HEAD
Whenever the camcorder needs to be removed from the head, hold the camcorder securely
with one hand and press "M" to release the plate and camera with the other hand, while keeping
the "T" button pressed down.
The purpose of the "T" Security Button is to ensure that the video camera is not released accidentally.

USE
For correct use, the head must be adequately levelled.
The head features 360° pan and vertical tilt (+90°/-70°) which are controlled using the pan bar "A" (fig. 10).
- the pan movement can be locked using the knob "V" and has adjustable drag control: friction is
increased by turning gear "E".
- the tilt movement can be locked using the knob "Q" and has adjustable drag control: friction is
increased by turning gear "P".
NOTE: the lever angle "V" can be positioned as required without affecting the lock itself. Pull the lever
outwards, turn as required and release: it will be set to the new position.

ATTACHING ACCESSORIES

In order to connect accessories please do not use the serrated rosettes "U". The head has a 3/8" female
thread "J" on both side with anti-rotation attachments "JM" which can be used to attach accessories
such as Manfrotto arms equipped with an anti-rotation system and anti-rotation attachments "JA" to
attach arms equipped with ARRI locating pins.
PLEASE NOTE: fitting additional accessories may require adjusting the head's balance and counterbalance
settings. An excessive load imbalance could compromise the tripod's stability and invalidate the quality
of the pan and tilt movements. In the worst cases, it could also compromise product safety.
USAGE ADVICE
Prior to using the product, especially after an extended period of disuse, it is advisable to restore
proper lubrication of the gas spring gaskets. This is done by rotating the head 3 times with the "A"
lever through the entire TILT travel range. Before use, please ensure that the central counterbalance
system area is free of any components that could affect the device's correct operation (dust, sand, etc.).
Gas piston performance is affected by varying temperatures: to maintain correct counterbalance with
high temperature variations, the counterbalance knob must be appropriately adjusted.
STORAGE
The product is NOT SUBJECT TO specific provisions for the carriage of dangerous goods by road
(ADR), rail (RID), inland waterway (ADN), sea (IMDG) and air (ICAO/ IATA).
We recommend transporting the equipment disassembled from the support and mounted on the head.
When not in use, the product must be stored with its PAN & TILT brake and Drag disengaged with
the plate holder in a horizontal position. Storage temperatures must range between -20°C and +60°C.
In case of extended periods of disuse, remove the battery from the light source (fig.4B).

MAINTENANCE

Clean the product only with non-aggressive detergents and soft cloths. Periodically remove dust and
sand from the locking screws and sliding parts. Do not use sharp or metallic tools when carrying out
cleaning procedures. After a long period of disuse, if squeaking sounds are heard in the piston area, the
cylinder shaft should be lubricated with a PTFE spray (not included).
CAUTION
While the head is moving, do not put your hands or insert tools in the piston area (fig. 12).
Keep the product away from children. Contains detachable parts that could be swallowed.
PRECAUTIONS
• Do not tamper with, modify or disassemble the product or any of its parts to avoid damaging its
performance or safety.
• Do not use the product outside the defined scope.
