Verify regularly the brake adjuster (19-42) wear conditions and their steady fastening on the rear cover brake
surface (17).
All brake assembly components, in particular the brake disc (23,) and the brake adjusters (19) are subject to
wear. In consideration of the motor safety role, it's needed to replace them periodically. The replacement
frequency comes from the motor duty (number of start/stop, applied moment of inertia, environment
conditions and so on), we recommend however to replace them at least every 18 months.
Periodically check and verify the shaft splines wear, exactly where the disc slides. If the shaft splines has a
visible wear it's necessary to replace the rotor shaft (1).
Check that the motor is properly mounted either through the feet or the flange. Check that the mounting bolts
are properly tightened. If the motor is foot mounted make sure that the feet aren’t cracked or otherwise
damaged. It is recommended to perform periodical inspections.
Periodically Check that the Terminal Box Gasket is in good condition and guarantees a proper enclosure of the
Terminal Box. If it’s damaged it must be replaced with a new one. It's recommended to perform inspections at
least once a year.
Each gasket used both for the motor and for the brake enclosure must be in good condition in order to
guarantee the proper protection degree. If one is damaged it must be replaced with a new one. It is
recommended to perform periodical inspections.
It is necessary to set a painting maintenance plan in order to assure the proper protection against corrosion.
