Exhaust Filter Cleaning Indicator


The following occurs when exhaust filter becomes restricted:

  • Service alert and exhaust filter cleaning indicators (on dash) are illuminated.
  • Engine power is reduced.
  • Information display will show “Parked Regen Required”

At this time, a parked exhaust filter cleaning is required.

Before a parked exhaust filter cleaning can be completed, the following criteria must be met:

  • Set engine rpm at low idle.
  • Coolant temperature must be above 60 deg°C (140°F).
  • Transmission must be in neutral.
  • Zero ground speed commanded.
  • Park brake must be engaged.
  • PTO must be turned off.
  1. IMPORTANT: Select a suitable space to park the machine and lower all implements to the ground.

    No other machine functions can be used while exhaust filter cleaning is taking place with the machine parked. Excluded from this are functions that are required for an emergency shutdown of the machine.

    Make sure the low fuel indicator is not displayed and there is at least 1/8 of a tank of fuel before starting regeneration.

    Only stop engine if absolutely necessary due to heat build up in the engine compartment.

  3. Soot Level will be displayed and engine speed will slowly increase.

  4. When the parked cleaning process is complete, the LED above the Exhaust Filter Cleaning Switch turns off. High exhaust temperature indicator (B) remains on for 30 seconds after completion and the engine speed returns to low idle.

  5. NOTE: If not returning machine to operation, allow engine time to return to normal operating temperature before stopping engine.

    After high exhaust temperature indicator (B) turns off, the system defaults to automatic exhaust filter cleaning mode and machine can be operated as normal.
