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 rechraged when it is warm due to
battery use or exposure to sunlight, the pilot lamp
may light in green.
The battery will not be recharged. In such a case,
let the battery cool before charging.
●
When the pilot lamp flickers rapidly 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.
BEFORE USE
Check the work area to make sure that it is clear of debris
and clutter.
Clear the area of unnecessary personnel. Ensure that
lighting and ventilation is adequate.
OPERATION
1. 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.
Matching socket and bolt sizes are shown Tables 6.
The numerical value of a socket designation denotes
the side-to-side distance (H) of its hex. hole.
2. Installing a socket (Fig. 6, 7-1)
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.

3. Retaining ring type (Fig. 6, 7-2)
(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
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.
4. Confirm that the battery is mounted correctly
5. Switch operation
The switch in this machine functions as a motor
switch and rotational direction selector switch. When
the switch is set to
motor rotates clockwise to tighten the bolt. When
the switch is set to
counterclockwise to loosen the bolt. When the switch
is released, the motor stops. (Fig. 8)
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.
