1 - GENERAL INFORMATION
Electro-Magnetic Compatibility (EMC)
Interference may arise as a result of add on equipment which may not necessarily meet the required standards.
Such interference can result in serious malfunction of the unit and/or create unsafe situations, you must observe the
following:
• The maximum power of emission equipment (radio, telephones, etc.) must not exceed the limits imposed by the
national authorities of the country where you use the machine.
• The electromagnetic field generated by the add on system should not exceed 24 V/m at any time and at any location
in the proximity of electronic components.
• The add on equipment must not interfere with the functioning of the on board electronics.
Failure to comply with these rules will render the CASE CONSTRUCTION warranty null and void.

Support strut and service link
WARNING
Crushing hazard!
If you service the machine with the loader lift arms raised, always use the support strut. Remove the
support strut from the storage position and place the strut onto the cylinder rod. Install the retaining
bolt entirely into the strut. Lower lift arms onto the support strut.
Failure to comply could result in death or serious injury.
W0140A
If you service the machine with the loader lift arms raised, always use the support strut.
Support strut
1. Empty the loader bucket, park the machine on a level
surface, raise the loader lift arms to approximately
2.1 m (7 ft), turn the engine off and set the parking
brake before exiting the cab. Maintain the bucket in a
dumped position. Remove the support strut from the
storage position by removing the retaining bolt.

mission declutch switch for more efficient braking. See
“Loader functions – Declutch switch" – Chapter 4 in this
manual for further information.
NOTICE: on steep slopes, use the down shift mode of
the transmission to aid braking and to help prevent brake
overheating and premature disc wear.
NOTE: when the machine is shut off, the parking brake is
automatically set.

Parking brake
WARNING
Run-over hazard!
Apply the parking brake before leaving the cab.
Failure to comply could result in death or serious injury.
W1390A
Parking brake button
Make sure the machine has come to a
complete stop before applying the parking
brake.
The parking brake button engages the parking brake on
the transmission output shaft.
NOTICE: the parking brake is a spring applied, hydraulic
released brake which is applied to the drive shaft. The
parking brake will effectively hold the machine in place
when used correctly.
LEIL16WHL1125AA 1
Engaging the parking brake
To engage the parking brake, move the transmission con-
trol lever to NEUTRAL (N), stop the machine and push
the parking brake button. The parking brake will automat-
ically engage when the machine is shut off.
NOTICE: a failure in the operating procedure or a failure
in the electrical or hydraulic function can result in abrupt
engagement of the parking brake. Always wear your seat
belt.
NOTICE: apply the parking brake prior to leaving the cab
and/or parking the machine on slopes.
Parking brake release
NOTE: the service brake must be at operating pressure
before the parking brake can be released to move the ma-
chine. The brake pressure indicator lamp on multifunc-
tion display must not be illuminated when disengaging the
parking brake. Attempting to move the machine prior to
the service brake pressures being sufficient causing low
operating pressure can result in premature parking brake
pad wear.

3 - CONTROLS AND INSTRUMENTS
Resetting the Selective Catalytic Reduction (SCR) system
After a failure or warning has been set, the SCR system must perform automatic tests to determine if failures or
warnings have been resolved. There are two categories of system warnings:
1. Electrical failures which only need key cycle to heal.
2. Failures which need an active Urea Dosing System to heal:
• Heated up SCR
• High engine speed and torque
The system must perform the following actions in order to recognize the resolved failures or warnings and reset itself.
1. For DEF/ADBLUE® level warnings:
a. Key switch must be cycled OFF then ON.
2. For poor DEF/ADBLUE® quality warnings:
a. Key switch must be cycled OFF then ON.
3. For SCR system warnings, one of the following conditions must occur, depending on the exact cause of the warn-
ing:
a. Requires the machine to be operated for approximately 20 min at a minimum of 50 % load to operate the SCR
system.
b. Requires starting and running the engine, but does not require the SCR system to operate.
c. Requires the key switch to be cycled OFF then ON.
Validation re-starts
Validation re-starts apply to the scenario “3a” of SCR system warnings (see list above). Validation re-starts allow
operation of the machine for up to 30 min without power loss after a poor DEF/ADBLUE® quality or SCR system fault
has been detected. Up to three re-starts are permitted. Re-starts are counted if either of the following conditions are
met:
1. Key off, wait 2 min for ECU after-run.
2. Key on, wait 5 - 15 s
3. Key off, wait 5 - 15 s
4. Key on, wait 5 - 15 s
5. Start
Normal operation will resume if a reset is detected within the 30 min window.
If a reset is not detected within 30 min, power loss will occur as described in the table above.
Validation re-starts are not available 7 min before severe inducement, or if inducement is activated a second time
within 40 h (inducements from low tank level are not considered toward validation restart availability)
If all three validation re-starts have been used and the system has not been reset, see your local authorized dealer
for repair.

turn the key to the START position. Once the engine
starts, allow it to run at low idle until the engine coolant
temperature is warm.
NOTE: if the engine starts and then stops, do not en-
gage the starter motor again until the starter motor
stops turning. Let the motor cool for two minutes be- LEIL16WHL1286AA 5
