The power supply, 90/260VAC-50/60Hz, is converted into 18-30V DC required by FAB and RAF series screwdrivers
through an electronic transformer with constant power of 120W. The electronic control circuit cuts the power supply to
the motor in response to the clutch action as soon as the pre-set torque has been reached.
On the front panel of the controller, there are two knobs indicated with the letters “R” and “A”.
Knob “R” is used to adjust the slow start option (ramp), but it’s only enabled for FAB and RAF screwdrivers, not for
KBL.
Knob “A” is used to adjust the motor speed for nominal speed, i.e. speed as per ctg. data sheet, to 60% of nominal
speed. Dial “1” for minimum speed and “10” for nominal speed.
On the front panel you can also see 2 lights: the green one will light permanently when the power is on, the red one will
light only when the clutch “fires” indicating the preset torque has been reached.
The temperature of the unit can normally reach 45°C.
On the back panel you can find a socket equipped with a fuse holder and on/off switch. To replace the fuse just pull out
the fuse holder and change the fuse.

5. Maintenance
Brushless screwdrivers and control units are maintenance-free. We suggest greasing the reduction after half a million
cycles.
Should you need any assistance please call your nearest Kolver dealer or repair centre.
Always remember to switch off the control unit at the end of each working shift.
NOTE
The sound level generated by Kolver electric screwdrivers is always lower than 70dB(A).
The vibrations transmitted to operator’s hand are lower than 2.5m/s². In particular the exposition to vibrations is lower
than 1m/s² for operators who make up to 4200 screwing cycles per day.
