DEF must be replaced periodically as it is consumed during operation. Determine if
replenishment of the DEF is necessary by reading the gauge displayed on the generator
controller.
Fill the DEF tank by pouring ISO-compliant DEF or AdBlue into the fill port indicated with the
“DEF or AdBlue” label and the blue cap. Avoid overfilling the DEF tank by watching the
gauge on the generator controller screen, and stopping the fill when the gauge reaches
100%.

NOTE:
When DEF level falls below 2.5% of the maximum capacity,
engine power output will be reduced to comply with emission
regulations. This may cause an interruption in power delivery to
attached aircraft.
