Emission System Temperature is High or Exhaust Filter Cleaning is Underway

The exhaust filter requires periodic maintenance. Some of the maintenance is transparent to the operator. During continuous heavy loads and other conditions, the engine creates enough heat to clean a small amount of soot build-up in the exhaust filter. When the exhaust filter has accumulated higher levels of soot, the ECU requests (depending on predefined user settings) an exhaust filter cleaning. During this request, move the equipment to a suitable location with adequate ventilation.

The following symbols may be displayed on the operator interface.

IMPORTANT: During an exhaust filter cleaning verify the area surrounding the engine is free of any flammable objects as temperatures can reach as high as 550°C (1022°F).

NOTE: For more information on the operator interface icons or exhaust filter cleaning procedures, see the Aftertreatment System section.
