Periodic Maintenance
The service hour meter determines the maintenance intervals or calendar intervals (daily,
weekly, monthly, etc.). Maintenance procedures are stated in this manual. Caterpillar
(Qingzhou) Ltd. requested maintenance should be done either by the service hour meter or the
time interval, whichever occurs first. Under extremely severe, dusty or wet operating
conditions, more frequent lubrication than is specified in the maintenance intervals schedule
might be necessary.
Other than daily maintenance schedules, four periodic maintenance points should be
considered: PM250: every 250 service hours, PM500: every 500 service hours, PM1000:
every 1000 service hours, and PM2000: every 2000 service hours
During maintenance, daily maintenance and initial maintenance of related components should
be strictly performed. Then, perform respective periodic maintenance according to specific
service hour.
