Inspection, maintenance, disposal

Clean according to the degree of local contamination in order to ensure that the waste heat
is adequately dissipated.
As the operating conditions vary greatly, one can only cite general intervals for fault-free
operation.
Guidelines:
- Bearing service life 20,000 hours
- Radial shaft seals approx. 5,000 hours with oil lubrication.
The encoder system must be readjusted each time after the motor has been
disassembled.
Dispose of the motor in accordance with the national and local regulations in the standard
recycling process or return it to the manufacturer.
Dispose of the encoder electronics properly as electronic scrap.
