Owner’s Manual for Mobile Generator
Reasonable care should be taken when refilling the DEF
tank. Verify the DEF tank cap area is free of debris before
removing the cap. Wipe clean with a lint free cloth to
remove debris from tank cap. Seal DEF containers
between use to prevent contamination and evaporation.
Avoid splashing DEF, and do not allow DEF to come into
contact with skin, eyes, or mouth.
NOTE:
Keep anything used to store or dispense DEF
clean of dirt and dust. Wash and rinse containers or
funnels thoroughly with distilled water to remove
contaminants.
If an unapproved fluid, such as diesel fluid or coolant is
added to the DEF tank, flush DEF tank with distilled
water, and fill with new or good DEF, contact a GMASD,
to determine how to clean and purge the system.
If water has been added to the DEF tank, a tank cleaning
is necessary. After refilling the tank, check the DEF
concentration. See
. The operator must
maintain appropriate DEF levels at all times. Check the
DEF level daily and refill the tank as needed. The filling
port is identified by a blue colored cap embossed with the
DEF symbol.
DEF Storage Guidelines
NOTE:
See the Materials Safety Data Sheet (MSDS) for
additional information.
DEF freezes at temperatures below 11.5 °F (-11.3 °C).
Do not use additives to reduce the freezing temperature.
Additives currently available are more corrosive than
DEF, and will cause component and system degradation
and negatively impact reliability. For more information,
see the operator manual, or contact a DEF supplier.
DEF quality degrades rapidly at temperatures above
140 °F (60 °C). To maintain emissions compliance, the
urea concentration must remain between 31.8–33.2%.
Ideal conditions for storage of DEF are:
•
Store at temperature range 23–86 °F (-5–30 °C)
•
Store in sealed dedicated containers to avoid
contamination and evaporation
Under these conditions, DEF is expected to remain
usable for a minimum of 18 months. Storing DEF at
higher temperatures can reduce its useful life by
approximately six months for every 9 °F (5 °C) above
86 °F (30 °C). Long-term storage in the DEF tank (over
12 months) is not recommended. If long-term storage is
necessary, test DEF before operating engine. See
DOC, SCR, and DPF Cleaning
Operations
The exhaust aftertreatment system goes through an
automatic cleaning process known as regeneration.
Under normal circumstances, regeneration occurs
without interrupting the unit operation.
NOTE:
Always park the unit in a safe location for
elevated exhaust temperatures and check for adequate
fuel level before beginning the exhaust aftertreatment
cleaning process. The cleaning cycle can take an
extended period of time (approximately 45 minutes).
Cleaning is complete when the regeneration indicator
remains off.
Diesel Particulate Filter Regeneration
NOTE:
See
emissions statement.
Regeneration is to increase the exhaust temperature for
a given time. The Aftertreatment Regeneration Device
(ARD) creates the heat which makes regeneration
possible. The regeneration process is used to remove
soot from the DPF, and warm up the Selective Catalyst
Reduction (SCR) system. The DPF traps both soot and
ash. The ash is removed through a manual cleaning
process. See
Diesel Particulate Filter—Clean
procedure on the service of the DPF.
WARNING
Risk of poisoning. Do not ingest diesel exhaust fluid.
Seek medical attention immediately if consumed.
Failure to do so could result in serious injury.

WARNING
Personal injury. Do not inhale diesel exhaust fluid fumes.
If breathing becomes difficult, move to an area with fresh
air and seek medical attention immediately. Failure to do
so could result in serious injury.
(000335a)
WARNING
Personal injury. Avoid contact with eyes. Flush eyes
thoroughly with water and seek medical attention
immediately. Failure to do so could result in serious
injury.
(000336)
WARNING
Risk of Burn. Stay clear of the exhaust system
during operation and exhaust filter cleaning.
Exposure to hot exhaust gases and components
could result in serious injury.
