Thawing
• Your CASE CONSTRUCTION machine is equipped with an internal tank heater to thaw frozen DEF/A
Your machine will still function until the DEF/A
NOTE: You may notice a slight reduction in engine torque in high demand situations until the DEF/A
thawed.
• Do not heat DEF/A B

to decompose, which very slowly decreases the expected shelf life.
NOTICE: Do not use an anti-gelling or freeze point improver in your DEF/A
designed to provide the optimum NO
mixture will lessen its ability to perform correctly and may cause damage to the SCR components.
Handling and supply of additives, if any.
• Personal Protective Equipment (PPE) is not required under normal conditions. If splashing is likely, wear eye pro-
tection. For prolonged or repeated contact, impervious gloves are recommended. Follow the precautions listed in

Shelf life
Constant ambient storage temperature
Less than or equal to 10 °C (50 °F)
Less than or equal to 25 °C (77 °F) ¹
Less than or equal to 30 °C (86 °F)
Less than or equal to 35 °C (95 °F)
Greater than 35 °C (95 °F)
¹ To prevent decomposition of DEF/A
be avoided.
² Significant loss of shelf life: check every batch before use. See your CASE CONSTRUCTION dealer for more
information on testing.
NOTE: The main factors taken into account to define the shelf life in the table above are the ambient storage tem-
perature and the initial alkalinity of DEF/A
storage containers is an additional factor.
