WARNING: To reduce the risk of injury, before using or servicing tool, read and understand the following information
as well as separately provided safety instructions (Item number: 0MS000). The features and descriptions of our products
are subject to change without prior notice.
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. 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
KOLVER screwdriving system is composed by a screwdriver, a cable with 2 x M12 female 5 pin connectors and a
power supply and control unit. To install it please follow the instructions.
a) Connect the 5-pin connectors of the cable to the controller and to the screwdriver and tighten the relevant nuts.
b) Connect the controller plug to a main supply socket 90 / 230V- 50/60Hz.
c) Switch the controller on through the black button on the back panel.
d) Select the desired setting of speed (A) through the relevant knobs. Please make sure that such setting is compatible
with the torque setting. Since the speed reduction is obtained through a voltage reduction (= power reduction), if the
torque setting is too high for a low speed setting, the clutch may not operate correctly and get stuck. In such a case, the
driver will not run and when you press the start lever the red light will signal. To reset the driver just turn the bit chuck
until you hear the clutch “click” (usually 180°). Increase the speed setting before running the driver again.
e) Do not slide the forward/reverse while the motor is running, it’s dangerous for the motor.
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 nut. After each adjustment lock the nut by means of the ring.
To increase the torque turn the nut clockwise, to decrease it turn the nut anticlockwise.
To change the spring remove the nut, replace the spring and then adjust the torque value as mentioned above.
To check the torque value we suggest the use of K5 or MINI K5 electronic torque tester.
4. Control unit and power supply
EDU 1FR power supply and control units act as voltage transformer and electronic torque controller.
