Information:

Literature Information
This manual contains recommended safety procedures, fluid systems specifications, operation instructions, maintenance information and basic troubleshooting along with basic repair information and should be stored in the pilot house or engine area. Read, study and keep it in a literature holder or literature storage area with other literature and engine information.Some photographs or illustrations in this manual show details or attachments that may be different from your engine. Guards and covers may have been removed for illustrative purposes. Continuing improvement and advancement of product design may have caused changes to your engine which are not included in this manual. Whenever a question arises regarding your engine, or this manual, please consult your Caterpillar dealer for the latest available information.Safety
The safety section lists basic safety precautions. In addition, this section identifies hazardous, warning situations. Read and understand the basic precautions listed in the safety section before operating or performing lubrication, maintenance and repair on this product.Operation
Operating techniques outlined in this manual are basic to assist with developing the skills and techniques required to operate the engine more efficiently and economically. Skill and techniques develop as the pilot gains knowledge of the engine and its capabilities.The operation section is a reference for experienced pilots, and photographs and illustrations guide the new pilot through correct procedures of inspecting, starting, operating and stopping the engine. This section also includes a discussion of gauges, indicators, features and controls.Maintenance
The maintenance section is a guide to engine care. Items in the Maintenance Schedule are referenced to detailed instructions that follow. The instructions and procedures are grouped by fuel consumption, service hours and/or calendar time maintenance intervals.Use fuel consumption first to determine intervals. Calendar intervals shown (daily, annually, etc.) may be used instead of service meter intervals if they provide more convenient schedules and approximate the indicated service meter reading.Recommended service should always be performed at the fuel consumption interval first. The actual operating environment of the engine also governs the maintenance schedule. Therefore, under extremely severe or freezing cold operating conditions, more frequent lubrication and maintenance than is specified in the Maintenance Schedule may be necessary.Maintenance Intervals
Perform maintenance on items at multiples of the original requirement. Each level and/or individual items in each level should be shifted ahead or back depending upon your specific maintenance practices, operation and application. We recommend that the maintenance schedules be reproduced and displayed near the engine as a convenient reminder. We also recommend that a maintenance record be maintained as part of the engine's permanent record.See the Maintenance Records section in this manual for information regarding documents that are generally accepted as proof of maintenance or repair. Your authorized Caterpillar engine dealer can assist you in tailoring your Maintenance Schedule to meet the needs of your operating environment.Overhaul
Your Caterpillar dealer offers a variety of options regarding overhaul programs. If you experience a major engine failure which necessitates removal of the engine from the hull, there are also numerous after failure overhaul options available from your Caterpillar dealer. Contact
