Maintenance - Manfrotto MVHN12AH Instructions Manual

Pull the lever outwards, turn as required and release: it will be set to the new position.
ATTACHING ACCESSORIES 11
The head has one 3/8" female thread "J" with an anti-rotation attachment which can
be used to attach accessories such as Manfrotto arms equipped with an anti-rotation
system.
Please note: fitting additional accessories may require adjusting the head's balance
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).
