Servicing
To maintain functionality of the oil seal, it must be lubricated regularly with oil. An oil seal that is not lubricated will
harden due to increased frictional heat and will eventually provide only dust protection.
Note:
Proper lubrication of the oil seal must be ensured throughout the entire service life of the motor.
For this reason, mounting a gearbox on motors with an oil seal is not permitted!
