Sound Level Information for Machines in European Union Countries and in Countries that Adopt the "EU Directives"
The declared 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 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.The declared exterior sound power level is 113 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 fan speeds.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 European Union Physical Agents (Vibration) Directive 2002/44/EC"
Vibration Data for Track-Type Tractors
Information Concerning Hand/Arm Vibration Level
When the machine is operated according to the intended use, the hand/arm vibration of this machine is below 2.5 meter per second squared.Information Concerning Whole Body Vibration Level
This section provides vibration data and a method for estimating the vibration level for track-type tractors.Note: Vibration levels are influenced by many different parameters. Many items are listed below.
Operator training, behavior, mode and stress
Job site organization, preparation, environment, weather and material
Machine type, quality of the seat, quality of the suspension system, attachments and condition of the equipmentIt is not possible to get precise vibration levels for this machine. The expected vibration levels can be estimated with the information in Table 1 in order to calculate the daily vibration exposure. A simple evaluation of the machine application can be used.Estimate the vibration levels for the three vibration directions. For typical operating conditions, use the average vibration levels as the estimated level. With an experienced operator and smooth terrain, subtract the Scenario Factors from the average vibration level in order to obtain the estimated vibration level. For aggressive operations and severe terrain, add the Scenario Factors to the average vibration level in order to obtain the estimated vibration level.Note: All vibration levels are in meter per second squared.
