| NMRV machine base model | Recommended lubricant grade | First oil change cycle | Subsequent oil change cycle | Applicable ambient temperature |
| 25-90 (aluminum shell version) | ISO VG320 synthetic gear oil | Continuous operation for 500 hours | Every 6000 hours | -15℃ ~ +40℃ |
| 110/130/150 (cast iron shell version) | AGIP BLASIA 460 Industrial Gear Oil | Operate for 150-400 hours | Not exceeding 4000 hours | -5℃ ~ +40℃ |
| Special low-temperature working conditions | Low freezing point synthetic gear oil | Execute according to the regular cycle | Execute according to the regular cycle | Below 0 ℃ environment |
Prohibition rule: Mixing of lubricating oils of different grades is prohibited, only oils of the same grade but different viscosities are allowed to be mixed.
Oil temperature limit: During normal operation, the maximum temperature of the lubricating oil should be controlled within 85 ℃. If it exceeds this value, the machine should be shut down for troubleshooting.
