The operator seat built into the machine by the manufacturer conforms to ISO 7096:2000, EM 6. When replacing the seat, ensure that the new seat also conforms to this standard.

Hand-arm vibration

If the machine is operated according to the manufacturer instructions, the weighted (frequency-rated) effective hand-arm vibration is below 2.5 m/s² according to ISO 5349-1:2001.

Whole-body vibration

If the machine is operated according to the manufacturer instructions, the weighted (frequency-rated) effective vibration shown for specific machine applications in the table below apply. These values conform to the specifications in the technical report ISO/TR 25398:2006 "Earth-moving machinery – Guidelines for assessment of exposure to whole-body vibration of ride-on machines – Use of harmonized data measured by international institutes, organizations and manufacturers". The method of assessment conforms to ISO 2631-1:1997. The effective values in the table for representable machines are shown with the applicable standard deviations. These deviations are classified according to the operating conditions in the classes "lightduty", "normal" and "heavy-duty". It is the responsibility of the machine owner to assess the operating conditions according to the classes, taking into account the terrain, site conditions, site organisation, material, machine equipment, working procedure and training of the operator.

As the quoted values are effective values for specific, common applications, the whole-body vibration to which the operator is exposed can only be estimated. For a more detailed assessment of the daily exposure of the operator across an 8-hour shift, please refer to the LIEBHERR brochure on whole-body vibration and the software designed for the assessment. This document and software are available from the LIEBHERR dealer and are included as standard on the documentation CD (Liebherr-Parts) shipped with new machines.

For instructions how to reduce whole-body vibration during operation of mobile construction machinery, please refer to chapter "Control, operation / working with machine / safety instructions / vibration protection".

The measurement uncertainty is defined in standard EN 12096:1997.

1.3Sound emission

The sound values of the machine are specified in the technical data. The sound power level (Lwa) is determined according to Directive 2000/14/EC. The measurement uncertainty of the sound power level value corresponds to the difference between the guaranteed and the measured value.

The sound pressure level (Lpa) is determined according to ISO 6396. The measurement uncertainty is defined in the above standard.
