Ensure that all of the safety signs are legible. Clean the safety signs or replace the safety signs if the words cannot be read or if the pictures are not visible. When the safety signs are cleaned, use a cloth, water, and soap. Do not use solvent, gasoline, or other harsh chemicals to clean the safety signs. Solvents, gasoline, or harsh chemicals could loosen the adhesive that secures the safety signs. The warning signs that are loosened could drop off of the engine.
Replace any damaged safety signs or missing safety signs. If a safety sign is attached to a part of the engine that is replaced, install a new safety sign on the replacement part. Any Caterpillar dealer can provide new safety signs.
Do not work on the engine and do not operate the engine unless the instructions and warnings in the Operation and Maintenance Manual are understood. Proper care is your responsibility. Failure to follow the instructions or failure to heed the warnings could result in injury or in death.
The safety signs that may be found on the engine are illustrated and described.
