OPERATOR'S STATION Refill DEF which meets JIS or ISO (International Organization for Standardization). If improper liquid (diesel oil, kerosene or gasoline) is refilled in the DEF tank, fire or system failure may result. Use only recommended engine oil. Using engine oil other than the recommended may result in malfunction of the aftertreatment device. Contaminated fuel, incorrect fuel additives, gasoline, kerosene or other incorrect fluids will damage the fuel injection system and will lead to engine malfunction, which is not covered by warranty. Incorrect fuels will also damage the aftertreatment device.
Use only clean Ultra Low Sulfur Diesel (ULSD) fuel without additives that contain metal elements, oil distillates or alcohol. These items will permanently damage the aftertreatment device and are not covered by warranty. Do not modify the machine without authorization. Never attempt to modify the air inlet and exhaust parts such as the air duct, aftertreatment device and the exhaust outlet. Also never attempt to disassemble the aftertreatment device. Avoid giving shocks on the aftertreatment device by hitting elements with other objects or dropping the device. Failure to do so may affect the aftertreatment device, possibly damaging it or lowering its performance.
It is normal to see white smoke appear during regeneration. It is not caused by a malfunction. Do not attempt to perform aftertreatment device manual regeneration indoors in an area that is not well ventilated or free from flammables. Ammonia odor may occur during aftertreatment device regeneration temporarily, but is not a trouble. Consult your authorized dealer for checking or repairing the aftertreatment device. 1-4
