For installations in zones 21 and 22 the User must schedule and implement a regular clea-
ning programme for all surfaces and recesses to avoid dust build-ups of more than 5 mm
in depth.
Every 1000 hrs. of operation or after 6 months:
•
Measure the surface temperature at the coupling between the gear unit and motor, and at the
points which are most shielded from the motor's cooling fan. The maximum temperature must
not be more than 75-80°C, nor may this value be exceeded during operation.
Every 5000 hrs. of operation:
•
Change the synthetic oil and bearing grease if the gear unit is not life lubricated.
•
Replace all externally accessible seal rings unless this has already been done as a result of
problems occurring before the scheduled maintenance deadline.
