Noise and vibration declaration statement

Guaranteed sound power level Lw according to ISO 3744 in accordance with directive 2000/14/EC.
Sound pressure level Lp according to ISO 11203.
Vibration value A and uncertainty B determined according to ISO 20643. See table "Noise and vibration data"
for the values of A, B, etc.
These declared values were obtained by laboratory type testing in accordance with the stated directive or
standards and are suitable for comparison with the declared values of other tools tested in accordance with
the same directive or standards. These declared values are not suitable for use in risk assessments and values
measured in individual work places may be higher. The actual exposure values and risk of harm experienced
by an individual user are unique and depend upon the way the user works, in what material the machine is
used, as well as upon the exposure time and the physical condition of the user, and the condition of the machine.
We, Atlas Copco Construction Tools AB, cannot be held liable for the consequences of using the declared
values, instead of values reflecting the actual exposure, in an individual risk assessment in a work place situation
over which we have no control.
This tool may cause hand-arm vibration syndrome if its use is not adequately managed. An EU guide to managing
hand-arm vibration can be found at http://www.humanvibration.com/EU/VIBGUIDE.htm
We recommend a programme of health surveillance to detect early symptoms which may relate to vibration
exposure, so that management procedures can be modified to help prevent future impairment.

Additional vibration information

This information is provided to assist in making rough estimates of the vibration value in the workplace.
The vibration emission varies greatly with task and operator technique. The declared vibration value relates to
the main handle(s) and much higher vibration levels may occur at other hand positions. We believe that normal
intended use of the tool will usually produce vibration emissions in the range of C
total values, as defined in ISO 5349-1:2001) depending on the details of the task, but emissions outside this
range may occur for some applications.

estimating the likely average exposures of users performing a wide range of tasks within the intended use of
the tool. We point out that application of the tool to a sole specialist task may produce a different average
emission and in such cases we strongly recommend a specific evaluation of the vibration emission.
