Passive DPF Regeneration
•
Passive regeneration occurs as part of normal
engine operation.
•
While operating the machine, run the engine at
full-engine speed and high load when possible to
promote DPF regeneration.
Assist DPF Regeneration
•
The engine computer adjusts engine settings to
raise the exhaust temperature.
•
While operating the machine, run the engine at
full engine speed and high load when possible to
promote DPF regeneration.
Reset Regeneration
CAUTION
The exhaust temperature is hot (approximately
600°C (1,112°F) during DPF regeneration. Hot
exhaust gas can harm you or other people.
•
Never operate the engine in an enclosed
area.
•
Make sure that there are no flammable
materials around the exhaust system.
•
Never touch a hot exhaust system
