MAINTENANCE
8.1
BOLTS TIGHTENING
Periodically check the tightness of all the fixing nuts. If necessary, ensure correct tightening by applying
the tightening torques shown in the table in paragraph 3.4.3.
8.2
GROUNDING CHECK
Periodically check the earth connections, especially the integrity of the cables and terminals and remove
any oxidation from the contacts.
8.3
CLEANING OF EBONITE COATINGS:
Cleaning and degreasing organic coatings is a delicate matter.
In the case of ebonite-coated
Euromag
flowmeters, please avoid any acid solution containing HF
(hydrofluoric acid) in any concentration.
The basic solution, such as NaOH, can be used, but only at room temperature. Normal soap is
recommended for removing grease and oil.
If cleaning with soap is not sufficient, washing with a solvent can also be carried out, using products
which evaporate rapidly; for example, acetone. In this case, the dirt must be removed with a cloth
moistened with acetone, an operation that must be done quickly to avoid aggression on the Ebonite,
and immediately afterward, the surface must be dried with a blow of air to allow the solvent evaporation.
