WARNING: To reduce the risk of injury, before using or servicing the 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 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 knob. 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, i.e.
screwing or unscrewing the threaded nut. 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..
