EXHAUST FILTER SERVICE REQUIREMENTS
The exhaust filter system contains a Diesel Particulate Filter (DPF). Over time, the DPF will require professional
servicing to remove ash buildup. The expected service interval will be at least 3,000 or 4,500 hours, based on engine
power and operating conditions. Actual service should take place when the indicator light appears on the Power
Zone™ controller. The DPF should be cleaned or replaced by an authorized service provider only. The removal of
DPF ash must be done by removing the DPF from the unit and placing it into specialized equipment.
CAUTION
Do not remove ash by using water or other chemicals. Removing ash by these methods
may cause equipment damage and create unsafe operating conditions.
CAUTION
Only a qualified service provider should remove, handle and dispose of DPF ash. These
materials may be considered hazardous under federal, state and local regulations, and must
be handled and disposed of properly.
To avoid unnecessary buildup of diesel particulates or soot in the exhaust filter system:
•
Utilize the Automatic Exhaust Filter Cleaning mode.
•
Avoid unnecessary idling.
•
Use proper engine oil. Refer to the engine operator’s manual.
•
Use only ultra low sulfur diesel fuel. Refer to the engine operator’s manual.
