Operation



Inserting and Removing the Battery
Push the charged battery into the battery holder until it clicks into place. To remove, press the battery release button and pull the battery out. Do not use force.
Setting Rotational Direction
Use the rotational direction switch (2) to change the direction. Right rotation: Press the switch to the left stop for driving screws and tightening nuts. Left rotation: Press the switch to the right stop for loosening screws and nuts. This cannot be changed while the on/off switch is pressed.
Speed Preselection
Press the mode button (12) to activate the user interface (6). You can preselect the speed in three stages. Press the mode button repeatedly until the desired setting is indicated on the speed indicator (10).
Automatic Bolt Release (ABR) Mode
The ABR function is designed for loosening bolts or nuts. The tool automatically shuts down as soon as the bolt or nut is released, preventing it from falling. This mode only works in left rotation and when the bolt/nut is still securely tightened.
