level
Use an oil expansion tank
Output shaft does not turn
although the motor is run-
ning or the input shaft is
rotated
Shaft-hub connection in the gear unit inter-
rupted.
Send in the gear unit/gearmotor for repair.
1) Short-term oil/grease leakage at the oil seal is possible in the run-in phase (168 hours running time).
2) During the run-in phase, the sealing lip grinds on the shaft and produces a path with a smoothed surface. Once the run-in phase has
been completed, the prerequisites for proper functioning of the seal are fulfilled.
