Literature Information
This manual contains safety, operation instructions, lubrication and maintenance information. This manual should be stored in or near the engine area in a literature holder or literature storage area. Read, study and keep it with the 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. Skill and techniques develop as the operator gains knowledge of the engine and its capabilities, and to assist with developing the skills and techniques required to operate the engine more efficiently and economically.The operation section is a reference for operators, and photographs and illustrations guide the operator through procedures of inspecting, starting, operating and stopping the engine.Maintenance
The maintenance section is a guide to engine care. The illustrated, step-by-step instructions are grouped by fuel consumption, service hours and/or calendar time maintenance intervals. Items in the Maintenance Schedule are referenced to detailed instructions that follow.Use fuel consumption or service hours 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 service hour interval. The actual operating environment of the engine also governs the maintenance schedule. Therefore, under extremely severe, dusty, wet or freezing cold operating conditions, more frequent lubrication and maintenance than is specified in the Maintenance Schedule may be necessary.The Maintenance Schedule items are organized for a Preventive Maintenance Program. If the Preventive Maintenance Program is followed, a periodic tune-up is not required. The implementation of a Preventive Maintenance Program should minimize operating costs through cost avoidances resulting from reductions in unscheduled downtime and failures.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
Major engine overhaul details are not covered in this manual except for the interval and the maintenance items
