Literature Information
This manual should be stored in the operator's compartment in the literature holder or seat back literature storage area.This manual contains safety information, operation instructions, and maintenance recommendations.Some photographs or illustrations in this publication show details or attachments that can be different from your machine.Continuing improvement and advancement of product design might have caused changes to your machine which are not included in this publication. Read, study and keep this manual with the machine.Whenever a question arises regarding your machine, or this publication, please consult your Cat 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 signs and labels used on the machine.Operation
The operation section is a reference for the new operator and a refresher for the experienced operator. This section includes a discussion of gauges, switches, machine controls, attachment controls, and programming information.Photographs and illustrations guide the operator through correct procedures of checking, starting, operating and stopping the machine.Operating techniques outlined in this publication are basic. Skill and techniques develop as the operator gains knowledge of the machine and its capabilities.Maintenance
The maintenance section is a guide to equipment care.California Proposition 65 Warning
Diesel engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm.Battery posts, terminals and related accessories contain lead and lead compounds.Wash hands after handlingCertified Engine Maintenance
Proper maintenance and repair is essential to keep the engine and machine systems operating correctly. As the heavy duty off-road diesel engine owner, you are responsible for the performance of the required maintenance listed in the Owner's Manual, Operation and Maintenance Manual, and Service Manual.It is prohibited for any person engaged in the business of repairing, servicing, selling, leasing, or trading engines or machines to remove, alter, or render inoperative any emission related device or element of design installed on or in an engine or machine that is in compliance with the regulations (40 CFR Part 89). Certain elements of the machine and engine such as the exhaust system, fuel system, electrical system, intake air system and cooling system may be emission related and should not be altered unless approved by Caterpillar.Cat Product Identification Number
Effective First Quarter 2001 the Cat Product Identification Number (PIN) will change from 8 to 17 characters. In an effort to provide uniform equipment identification, Caterpillar and other construction equipment manufacturers are moving to comply with the latest version of the product identification numbering standard. Non-road machine PINs are defined by ISO 10261. The new PIN format will apply to all Cat machines and generator sets. The PIN plates and frame marking will display the 17 character PIN. The new format will look like the following:
