IMPORTANT SAFETY NOTICE
Proper repair is important to the safe and reliable operation of a machine. 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 ON THIS MACHINE
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 the machine 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 an untrained mechanic and there is no way to label the
machine against all such hazards. These warnings in the Service Manual and on the
machine are identified by this symbol:
Operations that may result only in machine damage are identified by labels on the
machine and in the Service Manual by the word NOTICE.
Caterpillar cannot 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 machine
will not be damaged or made unsafe by the procedures you choose.
