Sound
Note (1)
The declared dynamic operator sound pressure level is 72 dB(A) when “ISO 6396:2008” is used to measure the value for an enclosed cab.
Note (2)
The measurement was conducted at 70% of the maximum engine cooling fan speed, with the cab doors and cab windows closed. The cab was properly installed and maintained. The sound level may vary at different engine cooling fan speeds.
Note (3)
The declared exterior sound power level is 104 dB(A) when the value is measured according to the dynamic test procedures and the conditions that are specified in “ISO 6395:2008.”
