8.2.3.2 Regular Maintenance
Below listed maintenance interval is suitable for “normal operation condition”. It should be
shortened on some severe conditions, such as too much dust, corrosive air, abnormal low
temperature, large load, very frequent or long-time operation circulation. Before
accumulating much experience for the maintenance, please observe the time interval in this
chapter.
If found that bearing and bushing is too hot, excessive loosen and rust for transmission
during the regular inspection, that means lack of lubrication, the lubrication cycle should be
shortened for the unusual parts.
Besides checking the reduction gearbox oil level in accordance with the maintenance time,
the lubricating oil also should be added on following two conditions:
-Before the first time startup
-Storage for over than three months
Note

Inspection should be done as required hours or specified time interval, whichever

maintenance work for 10 hours, 50 hours, 100 hours, 250 hours and 500 hours should
be done together.
The maintenance should be more frequently when the machine is operated in the moist
or dusty area.
