The sound values have been determined according to noise test code given in EN 607452-15, using the basic standards EN ISO 11094 and EN ISO 3744.

The noise figures quoted are emission levels and are not necessarily safe working levels. Factors that influence the actual level of exposure of work-force include the characteristics of the work room, the other sources of noise, etc. i.e. the number of machines and other adjacent processes, and the length of time for which an operator is exposed to the noise. Also the permissible exposure level can vary from country. This information, however, will enable the user of the machine to make a better evaluation of the hazard and risk.

Wear hearing protection! The sound intensity level for the operator may exceed 80 dB (A) and ear protection measures are necessary!

The declared vibration value has been measured in accordance with a standard test method (according to EN 12096) and may be used for comparing one product with another. The declared vibration value may also be used in a preliminary assessment of exposure.

This tool may cause hand-arm vibration syndrome if its use is not adequately managed.

WARNING!Depending on the actual use of the product the vibration values can differ from the declared total! Adopt proper measures to protect yourself against vibration exposures! Take the whole work process including times the product is running under no load or switched off into consideration!

Proper measures include among others regular maintenance and care of the product and cutting attachments, keeping hands warm, periodical breaks and proper planning of work processes!
