A - Cap

B - Diesel Exhaust Fluid (DEF) Tank Breather

Diesel Exhaust Fluid (DEF) contains urea. Do not get fluid in eyes. In case of contact, immediately flush eyes with large amounts of water for a minimum of 15 minutes. In event fluid is ingested, contact a physician immediately. Reference Materials Safety Data Sheet (MSDS) for additional information.

Using incorrect or unapproved aftertreatment components can cause damage to the vehicle’s aftertreatment system and reduce ability of the aftertreatment system to function correctly. Never interchange aftertreatment components between Interim Tier 4/Stage III B and Final Tier 4/Stage IV equipped vehicles.

If fluid is spilled or contacts any surface other than storage tank, immediately clean surface with clear water. Fluid is corrosive to painted surfaces and can distort some plastic and rubber components.

Cap (A) is not vented. Excess air is vented through Diesel Exhaust Fluid (DEF) tank breather (B).

Visually inspect the breather. Do not allow excessive amounts of chaff or debris to collect on breather. If the breather is covered with debris, it does not allow tank to breathe. Remove breather from hose and clean.

Fill tank every time machine is refueled. If this cannot be done, monitor Diesel Exhaust Fluid (DEF) level indicator on corner post display and refill as necessary. To avoid drastic changes in machine performance, always keep fluid level above the topmost red mark on the level indicator. See Combine Overview Application Help or Operator’s Station for further information.

To fill tank:

  1. Wash and rinse containers with distilled water to remove contaminants before adding fluid.
  2. Wipe area around the cap before removing to reduce chance of contaminating fluid.
  3. Using a funnel, carefully pour fluid into the tank, watching level through sight glass.
  4. Install previously removed cap.
  5. Carefully clean any spills, using distilled water.
