Your machine is equipped with an emission-compliant engine, which cleans and filters the engine exhaust. Under normal machine operation and with system in Automatic (AUTO) mode, the system requires minimal operator interaction. To understand when and where operator interaction is required, read the Exhaust Filter Cleaning sections.

To ensure that exhaust filter system operates as intended:

• Utilize AUTO exhaust filter cleaning mode.
• Avoid unnecessary idling.
• Use proper engine oil. (See Fuels, Lubricants, and Coolants section for recommendations.)
• Use only ultra low sulfur fuel. (See Fuels, Lubricants, and Coolants section for recommendations.)

NOTE: Exhaust filter cleaning mode switch (A) is a momentary contact switch. Normal (default) position is AUTO.

Use three position exhaust filter cleaning mode switch (A) to select exhaust filter cleaning modes; Parked Cleaning (B), AUTO Cleaning (C), and Auto Cleaning Disabled (D). To disable auto cleaning, exhaust filter cleaning mode switch needs to be depressed for 5 seconds.

IMPORTANT: Use disable mode (D) when temporarily connected to an indoor duct exhaust system for diagnostic and repair activities. Avoid disabled mode unless absolutely necessary. Repeated disabling or ignoring prompts to perform manual – parked cleaning procedure causes additional engine power limitation and eventually leads to required dealer service.

Exhaust filter cleaning will automatically reset back to AUTO mode when tractor is turned off and restarted.
