C - Disable Cleaning Switch

Your machine is equipped with an emission compliant engine, which cleans and filters the engine exhaust. Please read the Exhaust Filter Cleaning sections to understand when and where operator interaction is required.

IMPORTANT: Under normal machine operation, the system is in automatic mode and requires minimal operator interaction.

IMPORTANT: Soot builds up during times when engine exhaust gas temperature is lower (lower engine speed, lower engine load). Performing extended operations at either low engine speed (below 1500 rpm) or low engine load (such as backhoe work) could result in needing a parked exhaust cleaning. Periodically monitor the machine display during these operations to determine if parked exhaust cleaning is required.

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

  • Avoid unnecessary idling.
  • Use proper engine oil. (See the Service Engine section for recommendations.)
  • Use only ultra low sulfur fuel. (See the Service Miscellaneous section for recommendations.)

Under normal machine operation, the system is in automatic mode.

Use the control module (A) to select parked cleaning switch (B), or disable cleaning switch (C).

IMPORTANT: When machine use is not suited for higher temperatures created by exhaust filter cleaning, use the disable switch (C). Be sure to deactivate the disable switch as soon as possible to avoid unnecessary soot buildup in exhaust filter.

Remember to select disable switch (C) when temporarily connected to an indoor ducted exhaust system during vehicle diagnostic and repair activities.

  4. LX1049776
    LX1049776-UN-22JUL10

    Service Exhaust Filter Cleaning Required

    Description

    Recommended Procedure

    Extreme level of soot in exhaust filter. When this level of contamination is reached, service cleaning must be performed.

    NOTE: Engine power is reduced.

    Contact your John Deere dealer and get the dealer to service clean the exhaust filter. See Service Exhaust Filter Cleaning.
