Service and maintenance
7.1
Basic safety instructions
Servicing and maintenance of the load cells
The load cells are in general maintenance free. Regular inspection and checking of the
mechanisms for force transfer, oscillation limitation, lifting and overloading will however
improve their reliability. The inspections should also be performed after serious environmental
events such as storms, floods or earthquakes.
If signs of corrosion appear, we recommend a suitable protective coating.
NOTICE
Damage to load cells, measurement errors
• Dirt must not be allowed to accumulate in the vicinity of a load cell.
• Do not subject cable glands and seals to the jet from a high-pressure hose.
Regular maintenance of overload protection
Overload protection mechanisms must be protected against deposits of dirt and ice.
The correct operation of overload protection must be tested during periodic maintenance work.
7.2
Cleaning
Cleaning the enclosure
• Clean the outside of the enclosure with the inscriptions and the display window using a cloth
moistened with water or a mild detergent.
• Do not use any aggressive cleansing agents or solvents, e.g. acetone. Plastic parts or the
painted surface could be damaged. The inscriptions could become unreadable.
7.3
Return procedure
Enclose the bill of lading, return document and decontamination certificate in a clear plastic
pouch and attach it firmly to the outside of the packaging.
