You can change the impact force within approximately
one minute after releasing the switch trigger.
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 pull-
ing the trigger fully in counterclockwise tool rotation. When the bolt/
nut gets enough loosened, the tool stops the impact and rotation.
Application
Tool with the ring spring
For impact socket without O-ring and pin

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
► Fig.11: 1. Impact socket 2. O-ring 3. Pin
Move the O-ring out of the groove in the impact socket
and remove the pin from the impact socket. Fit the
impact socket onto the square drive so that the hole in
the impact socket is aligned with the hole in the square
drive.
Insert the pin through the hole in the impact socket and
square drive. Then return the O-ring to the original posi-
