If the machine will exceed a four month shut down period:
1. Perform a complete after-run procedure.
2. Drain the DEF/A B
D
3. Flush the tank with deionized water.
4. Drain the deionized water
NOTICE: do not disconnect any electrical connections from the SCR system.
Machine start-up after extended shutdown:
1. Fill the DEF/A B
D LUE
2. Replace the main filter in the supply module.
3. Start the machine.
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 components of the SCR system.
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
the SAFETY INFORMATION chapter when handling any service fluid.
• No additives are required.

Less than or equal to 30 °C (86 °F)
Less than or equal to 35 °C (95 °F)

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 tempera-
ture and the initial alkalinity of DEF/A
containers is an additional factor.
