Care and Maintenance
Service
Regular servicing by a Sartorius technician will extend the service life of your
equipment and ensure its continued weighing accuracy. Sartorius offers its
customers service contracts with regular maintenance intervals ranging from one
month to two years. The frequency of the maintenance intervals depends on the
operating conditions and the operator's tolerance requirements.
Repairs
2
Disconnect the power supply to the defective equipment immediately (unplug the
power cord from the mains supply). Repair work must be performed by authorized
Sartorius service technicians using original spare parts. Repairs performed by
untrained persons may result in considerable hazards for the user.

If a cable or cable gland is damaged or defective, replace the cable as a complete
unit with all its connectors.
