DEF/
AdBlue®
Filling
The 19 mm neck size prevents a standard diesel or
gasoline fill nozzle from being inserted into the tank
and a resulting miss fill.
Consult the LCD display in the cab to monitor DEF/
AdBlue®
quantity and refill as required.
Refill should be done every two or three times the die-
sel fuel tank is filled. Check the level at each refuel of
the diesel tank. Engine power adjustment and even-
tual shut down will occur in the event of insufficient or
poor quality DEF/
AdBlue®
supply.
Overfill and Freezing Protection
The DEF/
AdBlue®
tank requires an expansion volume
be maintained for when DEF/AdBlue® freezes in cold
weather. An expansion volume of approximately 10%
must be maintained. Overfilling of the tank will result in
tank rupture upon freezing.
Overfill protection is provided by the design of the
tank, allowing the flow to back-up into the nozzle and
activating its auto shut-off. After the nozzle is shut off,
a weep hole in the adapter will allow the DEF/AdBlue®
to slowly settle out of the adapter down into the tank. If
the operator then tops off the tank it will be subject to
freeze expansion risk.
The operator should NEVER
top off the DEF/AdBlue® tank.
DEF/AdBlue® trapped in hoses could freeze and dam-
age the PETU. Always take precautions to prevent
damage and emission problems.
NOTICE
DEF/
AdBlue®
is corrosive to some metals. Any
spill should be cleaned immediately.
NOTICE
Freezing hazard
Wait 2 minutes before turning off the battery
isolator switch after the diesel engine shut
down. If the battery isolator switch is turned off
immediately, the DEF/AdBlue® could be trapped
in hoses and freeze in cold temperature, caus-
ing damage to the system components.

The PETU contains a serviceable filter (which has to
be replaced every 5000 hours). Access to the filter
assembly requires the removal of the front cowling
panel. Ensure to empty the tank before proceeding
with the filter replacement.
To remove the filter cap, use a 27 mm Bi-Hex socket
tool.
Remove the expansion device inside the filter element
using the tool supplied with the new filter. Remove and
discard the used filter.
Install the new filter, expansion device and filter cap.
Tighten the filter cap to 20 N•m (15 ft-lb).
