SECTION 8 –
MAINTENANCE AND STORAGE
NOTE: When storing DEF in higher
temperatures for an extended period
of time, the shelf life will be reduced
by approximately 6 months for every
9° F (5° C) above the highest storage
temperature as previously listed.
Long-term DEF storage in a machine (in
excess of 6 months) is not recommended. If
long-term storage is necessary, periodic
testing of the DEF is recommended to ensure
adequate concentration. Having the correct
concentration of DEF is critical in engine and
aftertreatment system performance.
NOTE: To help prevent DEF deterioration
when stored in the DEF tank, locate
and plug the tank venting to seal tank
exposure against environmental
elements.
Checking DEF Concentration
DEF concentration should be checked
when the machine has been stored for an
extended period of time or if it is suspected
that water has been added to the DEF tank.
•
Use a refractometer to check DEF con-
centration.
NOTE: Refer to the engine manufacturer’s
operation manual for further
information on checking DEF
concentration.
•
If the DEF concentration is found to be
inadequate (outside of recommended
specification):
1. Drain the DEF tank.
2. Flush tank with distilled water.
3. Refill tank with new DEF.
4. Recheck DEF concentration.
Freezing
DEF will freeze around 12° F (-11° C). The
DEF system on the machine is designed to
accommodate this and does not require any
operator intervention.
DEF Disposal
Check with local authority regulations on
proper DEF disposal requirements.
Cooling System
The cooling system should be sufficiently
charged with an adequate mixture of
antifreeze and water, regardless of climate,
to maintain broad operating temperature
range. Follow the coolant manufacturer’s
recommendations for your climate.
NOTE: The cooling system has been
factory-filled with an ethylene glycol-
based antifreeze.
Capacity
•
Tier 4 Final Engines = 14 gal./53 L
•
Tier 3 Engines = 12.5 gal./47L (Export
only)
Checking Coolant Level/
Concentration
Check coolant level daily. Ensure fluid
level is visible within the sight gauge. Coolant
level is low if fluid is not seen in the sight
gauge.
CAUTION
DO NOT add any chemicals/additives to
the DEF in an effort to prevent freezing.
If chemicals/additives are added to the
DEF, the Aftertreatment System may
become damaged.
