Before each consecutive interval is performed, all of the maintenance requirements from the previous interval must also be performed.
The normal oil change interval for the engine is Every 500 Service Hours or 3 Months. If the engine is operated under severe conditions, change the oil after Every 250 Service Hours or 1 Month. Severe conditions include the following factors: high temperatures, continuous high loads and extremely dusty conditions .
Refer to the results of the S·O·S oil analysis in order to determine if the oil change interval should be decreased to 250 hours. Consult your Caterpillar Dealer for detailed information regarding the optimum oil change interval.
Refer to Operation and Maintenance Manual, "Hydraulic System Oil - Change" for information on a 4000 hour maintenance interval for the hydraulic system.
