1 - GENERAL INFORMATION
If the machine will exceed a four month shut down period:
1. Perform a complete after-run procedure.
2. Drain the DEF/ADBLUE® tank.
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/ADBLUE® tank.
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/ADBLUE®.
Your machine will still function until the DEF/ADBLUE® 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/ADBLUE® is fully
thawed.
• Do not heat DEF/ADBLUE® 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/ADBLUE®. The 32.5% solution is specifically
designed to provide the optimum NOx reduction properties. Any further blending or adjusting of the DEF/ADBLUE®
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.
NOTICE: contaminated DEF/ADBLUE® can affect the performance of your machine. Follow all instructions in this
manual when handling DEF/ADBLUE®.
Shelf life
Constant ambient storage temperature Minimum shelf life
Less than or equal to 10 °C (50 °F) 36 months
Less than or equal to 25 °C (77 °F) ¹ 18 months
Less than or equal to 30 °C (86 °F) 12 months
Less than or equal to 35 °C (95 °F) 6 months
Greater than 35 °C (95 °F) -²
¹ To prevent decomposition of DEF/ADBLUE®, prolonged transportation or storage above 25 °C (77 °F) should
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/ADBLUE®. 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/ADBLUE® 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.

When the machine is equipped with an auxiliary high-flow
hydraulic circuit, the right-hand control lever includes:
1. Proportional switch to operate double-acting hydraulic
attachments.
2. ON/OFF button to operate single-acting hydraulic at-
tachments.
3. Engine low idle speed button.
NOTICE: Do not operate controls for auxiliary high-flow
hydraulic circuit without setting any flow rate/pressure
combination. The circuit would work by default at max-
imum pressure, and this may lead to severe damages
to the attachment. For the setting procedure of auxiliary
high-flow hydraulic circuit, refer to Chapter 9.

Follow the steps below to add DEF/AdBlue®:
1. Turn the starter key to OFF position. Wait 3 min for SCR system to completely suck DEF/AdBlue® back into the
tank.
2. Unlock the front right-hand door (1) with the starter key. Open the door until it is fixed by the stay.
3. Unlock the DEF/AdBlue® tank cover (2) with the starter key. Turn the cover handle, and draw open the cover
leftward.
4. Wipe the inlet on the DEF/AdBlue® tank clean of dirt, mud, and foreign objects.
NOTICE: some white powder deposits may form when DEF/AdBlue® adheres and dries in places such as the
supply inlet. Wipe off these deposits to prevent them from entering the DEF/AdBlue® tank.
5. Turn the cap (3) counterclockwise and open the filler neck.
NOTICE: DEF/AdBlue® may emit an odor when the tank cap is opened. Do not attempt to smell inside the tank
from the supply inlet.
6. Refill up to the F (upper limit) mark (5) on the level gauge (4).
NOTICE: never refill DEF/AdBlue® over the F (upper limit) mark on the level gauge. Adequate air volume must
be present in the top of the tank for proper functionality of the after treatment system. Moreover, DEF/AdBlue®
