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:
⅜ 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.
⅜ 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.
⅜ 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. Selecting the socket matched to the bolt
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.
4. Installing a socket
Select the socket to be used.
ⅷ Pin, O-ring type
(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
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
(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.
CAUTION:
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.
⅜ 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. Operation of switch
The switch in this machine functions as a motor
switch and rotational direction selector switch. When
the switch is set to
R
indicated on the handle, the
motor rotates clockwise to tighten the bolt. When the
switch is set to
L
, the motor rotates counterclockwise
to loosen the bolt. When the switch is released, the
motor stops. (Fig. 6)
CAUTION:
Be sure to turn the switch OFF and wait until the
motor completely stops before changing the direction
of wrench revolution. Switching while the motor is
rotating will result in burning the motor.
2. About Remaining Battery Indicator
When pressing the remaining battery indicator switch,
the remaining battery indicator lamp lights and the
battery remaining power can be checked. (Fig.7) When
releasing your finger from the remaining battery
indicator switch, the remaining battery indicator lamp
goes off. The table 4 shows the state of remaining
battery indicator lamp and the battery remaining
power.

The battery remaining power
is enough.
The battery remaining power
is a half.
The battery remaining power
is nearly empty.
Re-charge the battery soonest
possible.
