In the plastic case there is an engine and a gear mechanism that drives a bit, which is installed at the end of a screwdriver. The device is provided for by the presence of a start toggle switch, a direction and speed switch, diode illumination and a tightening time regulator.
The principle of the tool is very simple. The nozzle, previously fixed in the cartridge, moves with the help of a shaft, which starts moving from the motor through a gearbox. Before using a screwdriver, you should find out if the battery is charged, and whether the correct nozzle is installed.
Immediately before doing the work, you need to look at such a nozzle so that it matches the head of a self-tapping screw or screw.

The end of the nozzle is placed in the groove of the screw. Before the device is started, check the accuracy of the installation of the direction of rotation, the direction should coincide with the screw tightening.
