Sound Level Information
Hearing protection may be needed when the machine is operated with an open operator station for extended periods or in a noisy environment. Hearing protection may be needed when the machine is operated with a cab that is not properly maintained or when the doors and windows are open for extended periods or in a noisy environment.The declared operator Equivalent Sound Pressure Level (Leq) is 77 dB(A) when "ANSI/SAE J1166 FEB 2009" is used to measure the value for an enclosed cab. This is a work cycle sound exposure level. The cab was properly installed and maintained. The test was conducted with the cab doors and the cab windows closed.The declared average exterior sound pressure level is 86 dB(A) when the "SAE J88Feb06 - Constant Speed Moving Test" procedure is used to measure the value for the standard machine. The measurement was conducted under the following conditions: distance of 15 m (49.2 ft) and “the machine moving forward in an intermediate gear ratio”.The declared exterior sound power level is 117.5 dB(A) when the value is measured according to the static pressure test procedures and the conditions that are specified in "ISO 6393:2008".The declared sound levels listed above include both measurement uncertainty and uncertainty due to production variation.Sound Level Information for Machines in European Union Countries and in Countries that Adopt the "European Union Directives"
The declared dynamic operator sound pressure level is 77 dB(A) when "ISO 6396:2008" is used to measure the value for an enclosed cab. The measurement was conducted at 100% of the maximum engine cooling fan speed. The sound level may vary at different engine cooling fan speeds. The cab was properly installed and maintained. The test was conducted with the cab doors and the cab windows closed.The declared sound levels listed above include both measurement uncertainty and uncertainty due to production variation.Sound Level Information for Machines in Eurasian Economic Union Countries
