| Sound Level Information for Machines in European Union Countries and in Countries that Adopt the “EU Directives.” The information below applies to only the machine configurations that have the “CE” mark on the Product Identification Plate. (1) | The declared dynamic operator sound pressure level is 76 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 cab was properly installed and maintained. The measurement was conducted with the cab doors and the cab windows closed. NOTE: This dynamic operator sound pressure level is associated to a 2 dB(A) uncertainty. |
| Sound Level Information for Machines in European Union Countries and in Countries that Adopt the “EU Directives.” The information below applies to only the machine configurations that have the “CE” mark on the Product Identification Plate. (2) | If equipped, the certification label – 110 dB(A) – is used to verify the environmental sound certification of the machine to the requirements of the European Union. The value that is listed on the label indicates the guaranteed exterior sound power level (LWA) at the time of manufacture for the conditions that are specified in “2000/14/EC.” Your machine may have a different value. |
| Sound Level Information (1) | The operator Equivalent Sound Pressure Level (Leq) is 81.5 dB(A) when “ANSI/SAE J1166 FEB2008” is used to measure the value for an enclosed cab. The measurement was conducted at 100% of the maximum engine cooling fan speed. 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. |
| Sound Level Information (2) | 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. |
| Sound Level Information (3) | The average exterior sound pressure level is 85.5 dB(A) when the “SAE J88 FEB2006 – 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.” |
