The instruments require no maintenance or servicing and will give very long
service when handled and operated properly.
The indicator and switching function should be checked once or twice every

with a pressure testing device.
The instruments should be cleaned with a damp cloth, moistened with soap
solution. It must be ensured that all the parts are dry before the power is
switched on again.
The residual pressure medium in dismounted pressure gauges may be
hazardous or toxic. This should be considered when handling and storing the
removed pressure gauges.
