1. DEF contains urea. Do not get the substance in eyes. In case of contact, immediately flush eyes with large amounts of water for a minimum of 15 minutes. Do not take internally. In event DEF is ingested, contact a physician immediately. Reference Material Safety Data Sheet (MSDS) for additional information.

   To determine tractor engine type, see Engine Serial Number in Identification Numbers Section of this Operator’s Manual.

   Initial replacement 1500 hours of operation or 1 year whichever comes first. Thereafter, replace every 4500 hours of operation or every 3 years, whichever comes first.

   Using incorrect or unapproved aftertreatment components can cause damage to vehicle’s aftertreatment system and reduce ability of 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 DEF is spilled or contacts any surface other than the storage tank, immediately clean the surface with clear water. DEF is corrosive to painted and unpainted metallic surfaces and may distort some plastic and rubber components.

   Procedure is similar for tractors with battery disconnect.
