1. Applications
KOLVER electric screwdrivers are used to tighten to the required torque screws,
nuts, studs and any other kind of threaded connection on any material. Table 1 will
help you to identify the capacity and the torque range of each model. Obviously, it
is possible to use the screwdrivers with screw having a larger diameter if the torque
fall within the indicated range. All models are reversible and can consequently be
used to unscrew. Electric screwdrivers are mainly used in the electronic industry as
well as for electric appliances, wiring, toys, lamps, glasses, in the mechanical light
industry etc.

2. Use
The screwing system is composed by a screwdriver, a cable with 5 pin connectors
and by a control unit and power supply. To install it please follow the instructions.
a) Connect the 5-pin plug of the cable to the controller socket and to the
screwdriver and tighten the relevant nuts.
b) Push the collect ring of the quick charge chuck towards the body of the
screwdriver, insert the desired bit into the exagonal seat ¼’’ and release the ring.
c)
Connect the controller plug to a mains supply socket 230V-50Hz.
d) Switch on the controller through the green light button “POWER”.
e) Position the bit head firmly into the fastener head, press the starting trigger and
run the faster down. The tool stops automatically when the preset torque is reached
and it is ready for the following operation.
3. Adjusting the torque
The torque value of the screwdriver is adjusted by changing the tension of the
clutch spring, screwing or unscrewing the threaded #2 nut. After each adjustament
lock the nut by means of #30 ring.
To increase the torque turn the nut clockwise, to decrease it turn the nut
anticlockwise.
Model Capacity Speed RPM Torque range Nm
FAB 10 RE M2,5 1000 0,05 – 0,8
FAB 12 RE M3 1000 0,2 – 1,4
FAB 18 RE M4 650 0,3 – 1,8
RAF 32 NS M5 1000 0,7 – 3,2
RAF 38 NS M5 650 0,9 – 4,1
The tool is equipped with an extra spring to reach the higher torque values
indicated in TABLE 1. To change the spring remove #2 nut, replace the spring and
then adjust the torque value as mentioned above.
To check the torque value we suggest the use of TL50i electronic torque tester.
WARNING: in cause the screwdriver does not stop automatically you should
reduce the torque setting by turning the #2 nut anticlockwise.
4. Control unit and power supply
EDU power supply and control units act as voltage transformer and electronic
torque controller.
The power supply 230V-50Hz AC is converted into 30V DC required by FAB and
RAF series screwdrivers through a transformer certified EN61558-1/p2-6.
The electronic control circuit cuts the power supply to the motor in response to the
clutch action as soon as the preset torque has been reached.
The table below summarizes all the possible combinations and different options.
Type of control unit Features Applications
EDU1NS
67VA, 1 plug, 1 speed
Metric screws or self
tapping screws on plastic
EDU1NS/RA

Table 2
Units EDU2CL is equipped with a two positions speed selector switch. When the
switch is in the “A” position the screwdriver will operate at the speed indicated in
table 1, when the switch is in “B” position the screwdriver will rotate at 70% of
the speed indicated in table 1.

All units are equipped with a power outlet on the back panel with autostopping fuse
holder certified IEC/CEE22. To replace the fuse just pull out the fuse holder and
change the fuse.
Always remember to switch off the control unit at the end of each working shift.
WARNING: always disconnect the mains plug of the power supply before
operating on the control units.
5. Maintenance
The screwdriver’s motor is equipped with carbon brushes 9mm long. When their
lenght is about 5mm it is time to replace them as per the following instructions:
a. Remove the #59 and #68 screws and the #54 and #58 housings.
b. Remove #53 brushes from their seat by delicately lifting up the #52
spring and desolder their wire.
c. Solder the wire of the new brushes, insert them into their seat and stop
them with the relevant #52 springs.
d. Re-mount the housing.

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.
