7.1.2 Inspection intervals of the GN motors
Carbon brushes and, to a limited extent also the collectors, are wearing parts in the case
of commutator machines.
As the wear of the carbon brushes to a great extent depends on the respective operating
conditions, we recommend the following inspection intervals:
– First inspection after approx. 100 operating hours
– Second inspection after 300 further operating hours
)
Note!
For safety reasons the inspection intervals should not exceed 1000 operating
hours!
