Important Safety Information
Most accidents that involve product operation, maintenance and repair are caused by failure to observe
basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous
situations before an accident occurs. A person must be alert to potential hazards, including human factors
that can affect safety. This person should also have the necessary training, skills and tools to perform these
functions properly.
Improper operation, lubrication, maintenance or repair of this product can be dangerous and could
result in injury or death.
Do not operate or perform any lubrication, maintenance or repair on this product, until you verify
that you are authorized to perform this work, and have read and understood the operation,
lubrication, maintenance and repair information.
Safety precautions and warnings are provided in this manual and on the product. If these hazard warnings
are not heeded, bodily injury or death could occur to you or to other persons.
The hazards are identified by the “Safety Alert Symbol” and followed by a “Signal Word” such as
“DANGER”, “WARNING” or “CAUTION”. The Safety Alert “WARNING” label is shown below.
The meaning of this safety alert symbol is as follows:
Attention! Become Alert! Your Safety is Involved.
The message that appears under the warning explains the hazard and can be either written or pictorially
presented.
A non-exhaustive list of operations that may cause product damage are identified by “NOTICE” labels on
the product and in this publication.
Caterpillar cannot anticipate every possible circumstance that might involve a potential hazard.

specifically recommended by Caterpillar is used, you must satisfy yourself that it is safe for you
and for others. You should also ensure that you are authorized to perform this work, and that the
product will not be damaged or become unsafe by the operation, lubrication, maintenance or repair
procedures that you intend to use.

When replacement parts are required for this
product Caterpillar recommends using Cat re-
placement parts.
Failure to follow this warning may lead to pre-
