Shibuya H2021 - Noise and Vibration Data

5.2 Noise information and vibration values determined in accordance with EN
62841
The sound pressure and vibration values given in these instructions have been measured in
accordance with a standardized test and may be used to compare one power tool with another. They
may be used for a preliminary assessment of exposure. The data given represents the main
applications of the power tool. However, if the power tool is used for different applications, with
different accessory tools, or is poorly maintained, the data may vary. This may significantly increase
exposure over the total working period. An accurate estimation of exposure should also take into
account the times when the power tool is switched off, or when it is running but not actually being
used for a job. This may significantly reduce exposure over the total working period. Identify
additional safety measures to protect the operator from the effects of noise and/or vibration, for
example: maintain the tool and the accessories and organization of work patterns.
The sound pressure and vibration have been measured under the following condition in accordance
with EN62841.
