Machine is equipped with emission compliant engine which cleans and filters exhaust gas. Under normal machine operation and with system in AUTO mode, system requires minimal operator interaction.

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

  • Utilize AUTO Exhaust Filter Cleaning mode.
  • Avoid unnecessary idling.
  • Use proper engine oil (see Diesel Engine Oil in Fuels, Lubricants, and Coolants Section of this Operator’s Manual).
  • Use only ultra low sulfur fuel (see Diesel Engine Oil in Fuels, Lubricants, and Coolants Section of this Operator’s Manual).

Exhaust Filter System Cleaning

IMPORTANT: Use disabled mode (D) when temporarily connected to an indoor ducted exhaust system for diagnostic and repair activities.

Exhaust Filter Cleaning will automatically reset back to AUTO mode after every key cycle.

There are two exhaust filter system modes: AUTO (C) and Disabled (D).

Parked Exhaust Filter Cleaning mode (A) may be active or inactive (grayed out) depending on exhaust filter restriction level (see Parked Exhaust Filter Cleaning later in this section of this Operator’s Manual).
