Note
All non-road Tier 4 Final/Stage IV diesel engines are required to use: The machine has the flexibility to run on either ultra-low-sulfur diesel fuel (ULSD with 15 ppm of sulfur or less) or up to B20 biodiesel when feedstock meeting ASTM D7467 specifications is blended with ULSD. Cat DEO-ULS or oils that meet the Cat ECF-3, API CJ-4, and ACEA E9 specifications are required. Only use DEF that meets ISO 22241-1 standards.

Operator Sound Level (Iso 6396)
72 dB(A)
Machine Sound Level (Iso 6395)
109 dB(A)
Note (1)
The operator sound pressure level was measured according to the test procedures and conditions specified in ISO 6396:2008. The measurement was conducted at 70 percent of the maximum engine cooling fan speed.
Note (2)
Hearing protection may be needed when the machine is operated with a cab that is not properly maintained or when the doors or windows are open for extended periods or in a noisy environment.
Note (3)
The machine sound power level was measured according to the test procedures and conditions specified in ISO 6395:2008. The measurement was conducted at 70 percent of the maximum engine cooling fan speed.
