Revision Summary of Changes
01 Updated the effectivity. A new Diesel Exhaust Fluid (DEF) filter is now available on machines listed above. The DEF filter has an improved filter efficiency.
Do not operate or work on this product unless you have read and understood the instruction and warnings in the relevant Operation and Maintenance Manuals and relevant service literature. Failure to follow the instructions or heed the warnings could result in injury or death. Proper care is your responsibility.
The following changes are now available for the products within the listed serial numbers.Refer to Table 2 for a list of a new and former part numbers.
