Exhaust Filter System

Your machine is equipped with an emission compliant engine that cleans and filters the exhaust. Under normal operation this system is automatic and requires no operator interaction. Please read this entire section to understand where and when operator interaction may be required.

There are things the operator can do to avoid unnecessary buildup of diesel particulates or soot in the exhaust filter system;

• Avoid unnecessary idling
• Operate engine at a higher rpm
• 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.)
• Only inhibit (disable) the exhaust filter cleaning system when absolutely necessary. (See Inhibit/Enable Exhaust Filter Cleaning System in this section.)

1. Press menu button (A) to access application menu.

2. Press engine button (B).

3. NOTE: Exhaust filter system will default to the auto setting when key is cycled even if the system has been previously disabled.

   Select desired mode.

   • Select Disable check box (C) to prevent filter cleaning from occurring.
   • Select Auto check box (D) to allow filter cleaning to occur automatically.
   • Press Request button (E) to request a parked filter cleaning.
   
   

Auto Cleaning Mode

CAUTION: Servicing machine or attachments during exhaust filter cleaning can result in serious personal injury. Avoid exposure and skin contact with hot exhaust gases and components.

IMPORTANT: During exhaust filter cleaning operation, the engine may operate at elevated idle.

A - Exhaust Filter Indicator

B - High Exhaust System Temperature (HEST) Indicator

NOTE: It is not recommended that engine be shut off during cleaning process or until engine has cooled to normal operating temperature after cleaning.

Disable Cleaning Mode

CAUTION: To prevent fires, be sure to routinely clear any combustible materials (crop debris, animal nests, etc.) from the area of the engine and exhaust filter. Exhaust filter cleaning uses extremely high temperature that can ignite dry residue.

C - High Exhaust System Temperature (HEST) Indicator

Be sure to enable the system as soon as possible to avoid soot buildup in the filter.

If the system determines there is excessive buildup in the exhaust filter due excessive idling or having the system in Disable mode for an extended period, exhaust filter indicator (B) will light informing the operator that an active cleaning is required and to place the system in the “Auto” mode and operate the machine in a normal fashion. High Exhaust System Temperature (HEST) indicator (C) will light and the operator may notice a small amount of white smoke from the exhaust pipe. No operator interaction is required during this process, continue operating the machine normally. Once filter has returned to an acceptable level indicator lights will go out.

IMPORTANT: If operator disregards indicators and continues to operate machine without allowing an active cleaning, engine performance will be reduced. Immediately allow an active filter cleaning to return engine back to original parameters. If engine will not return to original parameters after performing an active cleaning, a parked exhaust cleaning procedure must be performed.

Request (Parked) Cleaning Mode

CAUTION:

High Exhaust System Temperature (HEST) Indicator

A - Request Button

B - Exhaust Filter Indicator

C - High Exhaust System Temperature (HEST) Indicator

During Auto or Parked (stationary) exhaust filter cleaning operations, the engine will run at elevated idle and hot temperatures for approximately 30 minutes. Exhaust gases and exhaust filter components reach temperatures hot enough to burn people, ignite, or melt common materials.

NOTE: Request mode will not be available until the exhaust filter indicator (B) is activated.

Request mode is used if engine will not return to original parameters after performing an “Auto” mode cleaning. Exhaust Filter indicator will flash meaning that the soot level is high and a “Request” (Parked) filter cleaning procedure is required soon.

1. Park machine outdoors, away from any flammable material.

2. Set park brake, shut off solution system functions (solution pump) and reduce engine speed down to low idle.

3. Verify that fuel and DEF supply is adequate to operate machine for 30—45 minutes.

   NOTE: Length of cleaning process is dependent upon the level of exhaust filter restriction, ambient temperatures, and current exhaust gas temperature.

4. Select Request Button (A) to begin cleaning. Engine rpm will increase and an automatic process for cleaning the filter will begin.

At any time during the Request procedure, the process can be canceled by advancing the throttle, engaging transmission, or stopping the engine. Canceling cleaning is not recommended.

NOTE: It is not recommended that engine be shut off during cleaning process or until engine has cooled to normal operating temperature after cleaning.

Once the cleaning process has completed, engine rpm will return to idle and exhaust indicator lights will go out.

Machine can now be returned to normal operation. If you are not returning the machine to service immediately after the procedure, allow engine time to return to normal operating temperature before stopping engine.
