TOOL NOISE
The table 1bis of technical specifications indicates the noise level- where the noise level exceeds 85 dB (A) the acoustic
power is also indicated. Ear protectors must be worn where the noise level exceeds 85 dB (A) at the operator position. We
recommend that you also wear ear protectors below this noise level.
Noise risk and hearing damage are related to the intensity of the noise source and the length of exposure. Noise risk must
be assessed on a case by case basis taking into account these two factors. Measures should be taken to protect the user
against hearing damage in accordance with current Health and Safety regulations.
The formula and table can be used to calculate the daily exposure level for a tool using the use coefficient c. The use
coefficient c for grinders is between 30 and 60%.

TOOL VIBRATION
The table 1bis of technical specifications indicates the vibration level for the tool; the vibration level is calculated as the
squared weighted value of the acceleration frequency, Vibration risk is related to the intensity of the vibration source and
the length of exposure. Vibration risk must be assessed an a case by case basis taking into account these two factors.
Measures should be taken to protect the user against vibration injury in accordance with current Health and Safety
Regulations.
The formula and table can be used to calculate the daily exposure level for a tool using the use coefficient c. The use
