2. Checking the battery
Make sure that the battery is installed firmly. If it is at
all loose it could come off and cause an accident.
3. Installing the bit (WH12DM2, WH9DM2)
Always follow the following procedure to install driver
bit. (Fig. 5)
(1) Pull the guide sleeve back.
(2) Insert the bit into the hexagonal hole in the anvil.
(3) Release the guide sleeve and it returns to its original
position.
CAUTION:
If the guide sleeve does not return to its original
position, then the bit is not installed properly.
4. Selecting the socket matched to the bolt
(WR12DM2, WR9DM2)
Be sure to use a socket which is matched to the bolt
to be tightened. Using an improper socket will not
only result in insufficient tightening but also in
damage to the socket or nut.
A worn or deformed hex. or square-holed socket will
not give an adequate tightness for fitting to the nut or
anvil, consequently resulting in loss of tightening
torque.
Pay attention to wear of socket hole, and replace
before further wear has developed.
Finally, install the socket prescribed in Item 5. The
section on “Optional Accessories” details the
relationship between bolt sizes and sockets. Sockets
are named according to the dihedral width of the
hexagonal hole.
5. Installing a socket (WR12DM2, WR9DM2)
Select the socket to be used.
ⅷ Pin, O-ring type (Fig. 6 and 7)
(1) Align the hole in the socket with the hole in the anvil
and insert the anvil into the socket.
(2) Insert the pin into the socket.
(3) Attach the ring to the groove on the socket.
ⅷ Plunger type (Fig. 8)
Align the plunger located in the square part of the
anvil with the hole in the hex. socket. Then push the
plunger, and mount the hex. socket on the anvil.
Check that the plunger is fully engaged in the hole.
When removing the socket, reverse the sequence.
ⅷ Retaining ring type (Fig. 9)
(1) Align the square portions of the socket and the anvil
with each other.
(2) Make sure to firmly install the socket by pushing it all
the way into the anvil.
(3) When removing the socket, pull it out of the anvil.

⅜ Please use the designated attachments which are
listed in the operations manual and Hitachi’s catalog.
Accidents or injuries could result from not doing so.

the socket is not firmly installed it might come out
and cause injuries.
