      If oil is leaking from the breather valve of your SEW-Eurodrive Industrial Equipment, it could be due to having too much oil. In this case, correct the oil level. Alternatively, the drive might be installed in an incorrect mounting position. To resolve this, fit the breather valve correctly and adjust the oil level.
