Auto Exhaust Filter Cleaning

To avoid the unnecessary buildup of diesel particulates or soot in the exhaust filter system:

  • Utilize AUTO Exhaust Filter Cleaning mode.
  • Avoid unnecessary idling.
  • Use proper engine oil.
  • Use only ultra low sulfur fuel.

For more information, refer to Fuels and Lubricants section in the machine Operator's Manual.

When AUTO or PARKED cleaning is enabled, the exhaust temperature can be high under no load or light load conditions at certain times during the exhaust filter cleaning cycle.

Servicing machine or attachments during the exhaust filter cleaning can result in serious personal injury. Avoid exposure and skin contact with hot exhaust gases and components.

During auto or manual/stationary exhaust filter cleaning operations, the engine runs at elevated idle and hot temperatures for an extended period. Exhaust gases and exhaust filter components reach temperatures hot enough to burn people, or ignite, or melt common materials.

AUTO Mode— automated process that performs exhaust filter cleaning during normal operation.

Disable AUTO Exhaust Filter— in conditions where it can be unsafe for elevated exhaust temperatures.
