Prior To Operation; How To Use - Hitachi Koki WH 12DM2 Bedienungsanleitung

When the pilot lamp flickers in red (at 0.2-second
intervals), check for and take out any foreign objects
in the charger's battery installation hole. If there are
no foreign objects, it is probable that the battery
or charger is malfunctioning. Take it to your
authorized Service Center.
Since the built-in micro computer takes about 3
seconds to confirm that the battery being charged
with UC14YFA or UC14YF2 is taken out, wait for
a minimum of 3 seconds before reinserting it to
continue charging. If the battery is reinserted within
3 seconds, the battery may not be properly charged.

PRIOR TO OPERATION

1. Preparing and checking the work environment
Make sure that the work site meets all the conditions
laid forth in the precautions.
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)
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)
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)
Select the socket to be used.
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.
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.
