6. MAINTENANCE
1.
Regularly check the insulation resistance between the winding and the motor housing. The insula-
tion resistance must exceed 1MΩ when approaching operating temperature. Otherwise, other co-
rresponding measures should be taken.
2.
After normal operation for 2500 hours, maintenance work must be carried out according to the
following measures:
•
Oil change: Unscrew the oil plug to fill the oil chamber with 10# mechanical oil to 80-90%
of its capacity.
•
Pressure test: The pressure test shall be carried out after repair or replacement. The pressu-
re must remain 0.2 MPa with 3 minutes until there is no leakage or sweating.
