ASSEMBLY
CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed
before carrying out any work on the tool.
Selecting correct impact socket
Always use the correct size impact socket for bolts and
nuts. An incorrect size impact socket will result in inac-
curate and inconsistent fastening torque and/or damage
to the bolt or nut.
Installing or removing impact socket
CAUTION:
Make sure that the impact socket
and the mounting portion are not damaged before
installing the impact socket.
CAUTION:
After inserting the impact socket,
make sure that it is firmly secured. If it comes out,
do not use it.

8 ENGLISH
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
For impact socket without O-ring
and pin
► Fig.10: 1. Impact socket 2. Square drive
Align the hole in the side of the impact socket with the
detent pin on the square drive and push the impact
socket onto the square drive until it locks into place. Tap
it lightly if required.
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-
tion in the impact socket groove to retain the pin.
To remove the impact socket, follow the installation
procedures in reverse.
