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
Optional accessory
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.
NOTE: The way of impact socket installation varies
depending on the type of the square drive on the tool.
Tool with the ring spring
For TW004G
For impact socket without O-ring and pin
► Fig.10: 1. Impact socket 2. Square drive 3. Ring
spring
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-
tion in the impact socket groove to retain the pin.
To remove the impact socket, follow the installation
procedures in reverse.
Tool with the detent pin
For TW005G
► Fig.12: 1. Impact socket 2. Hole 3. Square drive
4. Detent pin
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. If it is
hard to remove, depress the detent pin while pulling the
impact socket.
Installing hook
CAUTION:
When installing the hook, always
secure it with the screw firmly. If not, the hook
may come off from the tool and result in the personal
injury.
► Fig.13: 1. Groove 2. Hook 3. Screw
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 indicator on the upper side of the button, it is not
locked completely. Insert it fully until the red indicator
cannot be seen. If not, it may accidentally fall out of
the tool, causing injury to you or someone around
you.
► Fig.14
Hold the tool firmly and place the impact socket over
the bolt or nut. Turn the tool on and fasten for the proper
fastening time.
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.
