Sound Level Information
The declared operator Equivalent Sound Pressure Level (Leq) is 70 dB(A) when "ANSI/SAE J1166 FEB 2008" is used to measure the value for an enclosed cab. This value 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.Note: When working in high ambient conditions and heavy work cycle conditions, the declared operator Equivalent Sound Pressure Level (Leq) is 75 dB(A) when "ANSI/SAE J1166 FEB 2008" is used to measure the value for an enclosed cab.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 average exterior sound pressure level is 78 dB(A) when the "SAE J88 FEB 2006 - 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”.Sound Level Information for Machines in European Union Countries and in Countries that Adopt the "European Union Directives"
Note: The information below applies only to machines that have the CE mark on the PIN plate.The static operator sound pressure level is 74 dB(A) when "ISO 6394:2008" is used to measure the value for an enclosed cab. The measurement was conducted with the cab doors and the cab windows closed. The cab was properly installed and maintained.The dynamic operator sound pressure level is 74 dB(A) when "ISO 6396:2008" is used to measure the value for an enclosed cab. The measurement was conducted with the cab doors and the cab windows closed. The cab was properly installed and maintained.The dynamic spectator sound pressure level is 105 dB(A) for the 12M and 120M and 106 dB(A) for the 120M AWD when "ISO 6395:2008" is used to measure the value for an enclosed cab. The measurement was conducted at 70% of the maximum engine cooling fan speed.Sound Level Information for Machines in Eurasian Economic Union Countries
The declared dynamic operator sound pressure level is 78 dB(A) when "ISO 6396:2008" is used to measure the value for an enclosed cab. The measurement was conducted at 70 % of the maximum engine cooling fan speed. The sound level may vary at different engine cooling fan speeds. The measurement was conducted with the cab doors and the cab windows closed.The declared exterior sound power level (LWA) is 106 dB(A) when the value is measured according to the dynamic test procedures and the conditions that are specified in "ISO 6395:2008". The measurement was conducted at 70% of the maximum engine cooling fan speed. The sound level may vary at different engine cooling speeds."The European Union Physical Agents (Vibration) Directive 2002/44/EC"
