switched off and the battery cartridge is removed
before carrying out any work on the tool.

curate and inconsistent fastening torque and/or damage
to the bolt or nut.

For approximately one minute after releasing the switch
trigger, the impact force can be changed.
Hard, Medium, and Soft impact mode allows a tighten-
ing suitable to the work.
The function of reverse rotation auto stop mode works
only with pulling the trigger fully in counterclockwise tool
rotation. When the bolt/nut gets enough loosened, the
tool stops the impact and rotation.
Application

Push the impact socket onto the square drive until it
locks into place.
To remove the impact socket, simply pull it off.
For impact socket with O-ring and pin
