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.
Do not strike any part of the assembly of the Diesel Particulate Filter (DPF). Do not allow any object to contact the internal element of the DPF. If the internal element of the DPF becomes damaged, the assembly must be replaced.Do not use power tools in order to disassemble or assemble any part of the Diesel Oxidation Catalyst (DOC), Diesel Particulate Filter (DPF), or the outlet section.
Refer to Operation and Maintenance Manual, "Diesel Particulate Filter - Clean" before starting any maintenance procedures on the assembly of the Diesel Particulate Filter (DPF).
