IMPORTANT SAFETY NOTICE
Proper repair is important to the safe and reliable operation of this product. This Service Manual outlines basic
recommended procedures, some of which require special tools, devices or work methods. Although not necessarily all
inclusive, a list of additional skills, precautions and knowledge required to safely perform repairs is provided in the SAFETY
section of this Manual. Improper repair procedures can be dangerous and could result in injury or death.
READ AND UNDERSTAND ALL SAFETY PRECAUTIONS
AND WARNINGS BEFORE PERFORMING REPAIRS
Basic safety precautions, skills and knowledge are listed in the SAFETY section of this Manual and in the
descriptions of operations where hazards exist. Warning labels have also been put on to provide instructions and identify
specific hazards which if not heeded could cause bodily injury or death to you or other persons. These labels identify
hazards which may not be apparent to a trained mechanic. There are many potential hazards during repair for a untrained
mechanic and there is no way to label the product against all such hazards. These warnings in the Service Manual and on
the product are identified by this symbol:
Operations that may result only in mechanical damage are identified by labels on the product and in the Service
Manual by the word CAUTION or NOTICE. Caterpillar can not anticipate every possible circumstance that might involve a
potential hazard. The warnings in this Manual are therefore not all inclusive. If a procedure, tool device or work method
not specifically recommended by Caterpillar is used, you must satisfy yourself that it is safe for you and others. You should
also ensure that the product will not be damaged or made unsafe by the procedures you choose.
