SECTION 8 –
MAINTENANCE AND STORAGE
8-6
Check the DEF Gauge (located on the
cab A-post) daily. Add just enough DEF to
keep the DEF tank full.
NOTE: Depending on the selected final
inducement option, 30 minutes after
the DEF Gauge reads 0%, the
engine will either be locked at idle or
will shut down. Refer to the engine
manufacturer’s service manual for
information on how to recover from a
low DEF level condition.
Capacity
•
DEF Tank Capacity = 10 Gallons (37 L)
Type
•
Use only DEF which meet ISO 2224101
standards.
NOTE: Refill tank with DEF every other fuel
fill to maintain adequate fluid level.
Filling the DEF Tank
Refer to “Engine Aftertreatment - Tier 4
Final” provided in the
Engine and Drive
Systems Section
elsewhere in this manual
for further information.
DEF Storage
DEF has a limited shelf life, both in the
machine’s DEF tank and in storage
containers. The following conditions are ideal
for maintaining DEF quality and shelf life
during prolonged transportation and storage:
•
Store DEF between 23° F (-5° C) and
77° F (25° C).
•
Store DEF in sealed containers to avoid
contamination.
•
Avoid direct sunlight.
By following these conditions, DEF has a
minimum expected shelf life of approximately
18 months.
NOTICE
Never operate the engine with low DEF
level. If DEF reaches a level that is too
low for safe operation, the engine will
begin to derate.
NOTICE
Ensure engine is off before filling the
DEF tank.
DEF Indicator Lamp Status
• When DEF level reaches 10% (indicated
on the DEF Gauge), DEF Indicator Lamp
will illuminate.
• When DEF level drops to 5%, DEF
Indicator Lamp will flash.
• When DEF level drops to 2.5%, initial
engine derate begins.
• When DEF level drops to 0%, secondary
engine derate begins.
