1.5 - MAINTENANCE
The weighing systems for mixer wagons do not require special maintenance
operations. However, in order to prevent problems in running or breakdowns, it is
advisable to carry out the following operations periodically:
• Check the perfect running of the power wires outside the equipment; also
check for the presence of oxides or humidity at the connection points.
It must be remembered that, very often in areas where food items are handled,
small rodents may be present, which can attack the cables placed even in
places that are not easily accessible.
• Check that the load cells do not show bruises; presence of any rust on the
body of the load cell does not impair proper running. Instead, check the
perfect adhesion between the silicon sealant and the body and the silicon
sealant and the cover, paying special attention to the presence of any cracks
in the sealant, as it may cause infiltration of moisture.
• Check that none of the accessories of the equipment show the presence of
bruises or signs of burning.
• Check, by loading a known weight on the mixer wagon, the correspondence
of the loaded weight with the displayed weight of the equipment.
• Check the fastening of all the screws present on the parts that constitute the
weighing system.
If the equipment needs cleaning operations, use a damp cloth, soft and without
fluff. Never use sprays, solvents, abrasives, pointed or cutting objects which may
damage the case.
