Power Service

Caterpillar products are a combination of advanced engineering, skilled manufacturing, and the finest materials metallurgical science can select. Thousands of satisfying, economical working hours are built into each engine.


Whether or not the owner derives the maximum of service from their engine, depends largely on the care exercised in its operation and maintenance. Caterpillar operation and maintenance manuals provide essential information regarding the day-to-day operation, lubrication, and adjustment of the machine. Careful adherence to these instructions will result in assured economy.
