Information:
This manual contains safety, operation instructions, lubrication and maintenance information.Read - study - and keep it handy.Some photographs or illustrations in this publication 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 publication.Whenever a question arises regarding your engine, or this publication, please consult your Caterpillar dealer for the latest available information.Safety
The safety section lists basic safety precautions. In addition, this section identifies the text and locations of warning labels used on the engine.Read and understand the basic precautions listed in the safety section before operating or performing lubrication, maintenance and repair on this product.Operation
Illustrations guide the operator through correct procedures of checking, starting, operating and stopping the engine.The operation section is a reference for the new operator and a refresher for the experienced one.The operating sections outlined in this publication are organized to assist you with developing the skills and techniques required to operate your engine more efficiently and economically.Maintenance
The maintenance section is a guide to equipment care. The illustrated, step-by-step instructions are grouped by Preventive Maintenance servicing intervals. Items in the "Maintenance Management Schedule" are referenced todetailed instructions that follow.The "Maintenance Management 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 Management Program should minimize operating costs through cost avoidances resulting from reductions in unscheduled downtime and failures.Maintenance Intervals
The service interval for each item listed in the "Maintenance Management Schedule" is primarily based on the item and its relationship to either engine speed or load.We recommend that these schedules be reproduced for ease of inspection. We also recommend that a maintenance record be maintained as part of the equipment's permanent record.See the "Maintenance Log" section of this publication for information regarding documents that are generally accepted as proof of maintenance or repair.Your authorized Caterpillar dealer can assist you in tailoring your schedule to meet the needs of your operating environment.
