Installing or removing socket
► Fig.5: 1. Socket 2. Anvil
1. For socket without O-ring and pin
To install the socket, push it onto the anvil of the
tool until it locks into place.
To remove the socket, simply pull it off.
2. For socket with O-ring and pin
► Fig.6: 1. Socket 2. O-ring 3. Pin
Move the O-ring out of the groove in the socket
and remove the pin from the socket. Fit the socket
onto the anvil of the tool so that the hole in the
socket is aligned with the hole in the anvil. Insert
the pin through the hole in the socket and anvil.
Then return the O-ring to the original position in
the socket groove to retain the pin. To remove
the socket, follow the installation procedures in
reverse.
Align the hole in the side of the socket with the detent
pin on the anvil and push it onto the anvil of the tool until
it locks into place. Tap it lightly if required.
To remove the socket, simply pull it off.
Hook
CAUTION:
After installing the hook, make sure
that it is screwed firmly.
► Fig.7: 1. Groove 2. Screw 3. Hook
The hook is convenient for temporarily hanging the tool.
This can be installed on either side of the tool.
To install the hook, insert it into a groove in the tool
housing on either side and then secure it with a screw.
To remove, loosen the screw and then take it out.

OPERATION

CAUTION:
• Always insert the battery cartridge all the way
until it locks in place. If you can see the red part
on the upper side of the button, it is not locked
completely. Insert it fully until the red part cannot
be seen. If not, it may accidentally fall out of the
tool, causing injury to you or someone around
you.
Hold the tool firmly and place the socket over the bolt or
nut. Turn the tool on and fasten for the proper fastening
time.
► Fig.8
The proper fastening torque may differ depending upon
the kind or size of the bolt, the material of the workpiece
to be fastened, etc. The relation between fastening
torque and fastening time is shown in the figures.

• Excessive fastening torque may damage the
bolt/nut or socket. Before starting your job,
always perform a test operation to determine the
proper fastening time for your bolt or nut.
• If the tool is operated continuously until the
battery cartridge has discharged, allow the tool
to rest for 15 minutes before proceeding with a
fresh battery cartridge.
