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

EBM1830, BCL1840
(3) Regarding recharging time
Depending on the combination of the charger and batteries, the charging
time will become as shown in Table 3.

NOTE
The charging time may vary according to 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
After operation, pull out batteries from the charger first, and then keep the
batteries properly.
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
When the battery charger has been continuosly used, the battery charger
will be heated, thus constituting the cause of the failures. Once the charging
has been completed, give 15 minutes rest until the next charging.
If the battery is recharged when it is warm due to battery use or exposure to
sunlight, the pilot lamp map light in green.
The battery will not be recharged. In such a case, let the battery cool before
charging.
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.

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 (WH14DL2 / WH18DL2)
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
(WR14DL2 / WR18DL2)
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.
5. Installing a socket (WR14DL2 / WR18DL2)
Plunger type (Fig.5)
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.
CAUTION
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.
Make sure to firmly install the socket in the anvil. If the socket is not firmly
installed it might come out and cause injuries.

HOW TO USE

1. Check the rotational direction
The bit rotates clockwise (viewed from the rear side) by pushing the R-side
of the push button.
The L-side of the push button is pushed to turn the bit counterclockwise.
L R
(See Fig. 6) (The and
CAUTION
The push button cannot be switched while the impact driver is turning. To
switch the push button, stop the impact driver, then set the push button.
2. Switch operation
When the trigger switch is depressed, the tool rotates. When the trigger is
released, the tool stops.
The rotational speed can be controlled by varying the amount that the
trigger switch is pulled. Speed is low when the trigger switch is pulled
slightly and increases as the trigger switch is pulled more.
NOTE
A buzzing noise is produced when the motor is about to rotate. This is only
a noise, not a machine failure.
3. Change rotation speed
As shown in Fig. 7, when the rotation switch-over lever is slid to the lower
side, the power mode (P) is set. And when slid to upper side, the save mode
(S) is set.
Please use the save mode (S) when you want to lower Maximum tightening
torque.
