Air inlet 1/4" GAS - Ø inside tube min. 8 mm - square connection 1/2"
Noise emission levels determined by using ISO/CD 15744
Levels of vibrations at the handle determined by using ISO 8662
Pressure: 6-6.2 bar during functioning.
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.
CLUTCH
The gear clutch has the function of transmitting to the bit, and therefore to the screw, only part of the torque that may be
produced by the screwdriver so as to ensure optimal screw-tightening conditions. It also makes it possible to maintain a
highly constant level of torque when tightening screws in sequence. The range of clutch settings is determined by the
spring. Two springs are available, each one covering a range of torque values. Each screwdriver is supplied with the
spring specified in table 2. If you should wish to obtain a level of torque outside its range of settings, you may request
other springs.

* Maximum tightening torque value with functioning of the motor stop, also under flexible tightening conditions.
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 a screwdriver is between 10 and 35%.

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.
The formula and table can be used to calculate the daily exposure level for a tool using the use coefficient c. The use
