Wear goggles, gloves, protective clothing, and a National Institute for Occupational Safety and Health (NIOSH) approved P95 or N95 half-face respirator when handling a used Diesel Particulate Filter or Catalytic Converter Muffler. Failure to do so could result in personal injury.
The muffler, catalytic converter/muffler, and diesel particulate filter will become extremely hot during engine operation. A hot muffler, catalytic converter/muffler and diesel particulate filter can cause serious burns. Allow adequate cooling time before working on or near the muffler, catalytic converter/muffler and diesel particulate filter.

Note: Only the wall flow type of aftertreatment requires a service period, in order to remove the ash. The wall flow aftertreatment uses active regeneration in order to remove soot.For information on removal of the (1) diesel particulate filter, refer to Disassembly and Assembly, "DPF - Remove". Only ultra low sulfur diesel fuel can be used in an application that has an aftertreatment system installed.Caterpillar recommend the use of Cat DEO-ULS engine oil.
