(2)Regarding the temperatures of the rechargeable battery The temperatures for rechargeable batteries are as shown in the table below, and batteries that have become hot should be cooled for a while before being recharged.

(3)Regarding recharging time
Depending on the combination of the charger and batteries, the charging time will become as shown in Table 7.

NOTE:
The charging time may vary according to the ambient temperature and power source voltage.
4.Disconnect the charger’s power cord from the receptacle.
5.Hold the charger firmly and pull out the battery. NOTE:
Be sure to pull out the battery from the charger after use, and then keep it.
Regarding electric discharge in case of new batteries, etc.
As the internal chemical substance of new batteries and batteries that have not been used for an extended period is not activated, the electric discharge might be low when using them the first and second time. This is a temporary phenomenon, and normal time required for recharging will be restored by recharging the batteries 2 – 3 times.
How to make the batteries perform longer
(1)Recharge the batteries before they become completely exhausted.
When you feel that the power of the tool becomes weaker, stop using the tool and recharge its battery. If you continue to use the tool and exhaust the electric current, the battery may be damaged and its life will become shorter.
(2)Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate,
and the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while.
CAUTION:
◯If the battery is charged while it is heated because it has been left for a long time in a location subject to direct sunlight or because the battery has just been
used, the pilot lamp of the charger lights up green. In such a case, first let the battery cool, then start charging.
◯When the pilot lamp flikers in red quickly (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
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, WH9DM2, WH12DMR) Always follow the following procedure to install driver bit. (Fig. 4)
(1)Pull the guide sleeve away from front of the tool.
(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
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.
⬤Pin,
(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. 7)
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.
