For torque above 200 Nm
Atlas Copco recommends that the holes at the front of the tool are used for the fixture.
If this is not possible, place the clamps further back on the tool.
For tools below 300 Nm, place the clamp on the gearbox.
If this is not possible, place the clamp on the motor.
For tools from 300 Nm and upwards, use one clamp around the gearbox and one clamp around the motor.
Make sure that the center axes for the two clamps are aligned.
