Technical data
6.8 Noise levels
Information!
Measurements performed on asphalted surface.
6.9 Vibration
Vibration values indicated in m/s².
Directive 2002/44/EC of European Parliament and Coucil on minimum health and safety
requirements regarding exposure of workers to risks arising from physical agents (vibra-
tion).
Indications on hand-arm vibration
Hand-arm vibration is less than 2.5 m/s² during correct machine operation.
Indications on whole-body vibration
Whole-body vibration is less than 0.5 m/s² during correct machine operation.
Uncertainty of measurement K has been taken into account for the specified values.
The degree of vibration is influenced by various parameters.
Some of them are listed below:
• Operator: training, behavior, working method and strain.
• Work site: organization, preparation, surroundings, weather conditions and material.
• Machine: version, seat quality, quality of suspension system, attachments and
condition of attachments.
Precise indications on the vibration degrees cannot be made for the machine.
Determination of vibration level for the three vibration axes.
• Under typical operating conditions, use the average vibration values measured.
• In order to obtain the estimated vibration value for an experienced operator on level
ground, subtract the factors from the average vibration value.
• In case of an aggressive working method or difficult terrain, add the environmental
factors to the average vibration level in order to obtain the estimated vibration level.
