Operating instructions

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/humanvibration/EU/VIBGUIDE.html
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.
