Maintenance
Maintenance of the meter is carried out by the personnel of the manufacturer or service center. The scope of maintenance work is determined by the maintenance specialist after checking the technical condition of the meter. For work related to cleaning of internal surfaces, repair or replacement of parts, repair or replacement of electronic components, calibration of the meter, it is transferred to the service center or the manufacturer's enterprise. For the duration of such maintenance, another meter or insert fitting is installed (upon agreement).
Maintenance is carried out after installation of the meter and periodically. Periodic maintenance is recommended every 12 months or 100 000 liters for the M2M F2 or 200 000 liters for the M2M F5. The frequency of maintenance may vary depending on the quality of the fuel, the condition of the filters, operating conditions, and the condition of the fuel system.
Safety instructions
Read all instructions carefully before use.
When working on auto-tractor machinery, safety rules must be followed when working with fuel liquids. When installing the meter, you must follow the safety rules adopted at yourcompany.
It is forbidden to turn on the meter at a voltage higher than the range specified in this document. When welding is done, it is necessary to unlock it from the power supply and disconnect the connector.
