9.2.2 check air gap
As a result of wear occurring during operation, the air gap increases. To ensure proper
functioning, the air gap X needs to be checked at regular intervals.When checking the
air gap pay attention that parallelism and axial run-out tolerances must be added to the
rated air gap X.
