Noise emission levels determined by using ISO/CD 15744
Levels of vibrations determined by using ISO 8662
Note: make sure that the performance features required correspond to those described above, otherwise it will be
necessary to choose a different model from the broad range offered by OBER.
TOOL NOISE
The table of technical specifications indicates the noise level- where the noise level exceeds 85 dB (A) the noise 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 sanders is between 30 and 60%.

TOOL VIBRATION
The table 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.

MATERIALS
OBER pneumatic tools consist of parts in steel, aluminium, cast iron, rubber and plastic and do not contain substances
which damage the environment or are harmful to people. However, the individual materials must be disposed of
separately, following the National indications for recycling and handling waste.
