EXHAUST FILTER CLEANING OPERATIONS
When enabled, the exhaust filter system goes through an automatic cleaning process knows as regeneration. Under
normal circumstances, regeneration occurs without interruption of unit operation and with minimal operator involve-
ment. In the event there are conditions requiring the operation of the unit with the auto exhaust filter cleaning disabled,
the operator may be required to perform procedures to enable or disable the auto exhaust filter cleaning. The operator
may also be required to perform a manual regeneration. The following procedures describe how to perform these
functions.
WARNING
The area above and surrounding the exhaust system during an auto or manual exhaust
filter cleaning should be clear of any people and objects. Exhaust gases and compo-
nents can reach temperatures hot enough to ignite and melt common materials.
Note:
Always park the unit in a safe location for elevated exhaust temperatures and check for adequate fuel level
before beginning the exhaust filter cleaning process. The cleaning cycle can take an extended period of time
(approximately 45 minutes). Cleaning is complete when the Regeneration indicator remains off.
