7 - MAINTENANCE
Cold weather handling
• Your machine is equipped with an internal tank heater to thaw frozen
DEF/A
D
B
LUE
®
. Your machine will still function
until the
DEF/A
D
B
LUE
®
begins to flow. The SCR system will then function normally.
NOTE:
You may notice a slight reduction in engine torque in high demand situations until the
DEF/A
D
B
LUE
®
is fully
thawed.
• Do not heat
DEF/A
D
B
LUE
®
for long periods of time at temperatures above
30 °C
(
86 °F
). This causes the solution
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
D
B
LUE
®
. The
32.5%
solution is specifically
designed to provide the optimum NOx reduction properties. Any further blending or adjusting of the
DEF/A
D
B
LUE
®
mixture will lessen its ability to perform correctly and may cause damage to the SCR components.
Handling and supply of additives
• 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.
NOTICE:
contaminated
DEF/A
D
B
LUE
®
can affect the performance of your machine. Follow all instructions in this
manual when handling
DEF/A
D
B
LUE
®
.

¹ To prevent decomposition of
DEF/A
D
B
LUE
®
, avoid prolonged transportation or storage above
25 °C
(
77 °F
).
However, temporary exposure to higher temperatures does not necessarily influence the quality of
DEF/A
D
B
LUE
®
.
² Significant loss of shelf life: check every batch before use. See your authorized 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
D
B
LUE
®
. The difference in evaporation between vented and non-vented storage
containers is an additional factor.
NOTE:
the information in this table is for reference only and has been provided by the International Organization for
Standardization, Document number ISO 22241-3 Diesel engines - NOx reduction agent AUS 32 - Part 3: Handling,
transportation and storage.
NOTE: DEF/A
D
B
LUE
®
that remains in the tank of the machine after the season does not require any special precau-
tions unless storage exceeds the shelf life table above.
Disposal
• Dispose of
DEF/A
D
B
LUE
®
and any filter accumulations in accordance with all applicable Federal, State, and local
laws governing waste disposal.
