Shut OFF engine, set park brake and remove key before performing maintenance work.

Long-term storage in vehicle (over 12 months) is not recommended. If long-term storage is necessary, periodic testing of fluid is recommended to ensure that urea concentration does not fall out of specification.

If an unapproved fluid, such as diesel fuel, or engine coolant is added, drain tank and rinse with distilled water, then refill tank. If system does not operate correctly after cleaning and refilling, contact your John Deere dealer to determine how to clean and purge system. If water has been added to tank, drain tank, flush with distilled water and refill with Diesel Exhaust Fluid (DEF). Check concentration of fluid after filling tank. See Fuels and Lubricants section for testing.

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.

Attach hose to the fitting (A) at bottom of tank.

Use the handle (B) to open the drain valve.

Close the drain valve and remove the hose once fluid is drained.
