4. Installing a socket
Select the socket to be used.
Pin, O-ring type (Fig. 5 and Fig. 6)
(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.
Retaining ring type (Fig. 8)
(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.

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. 9) (The and
CAUTION:
The push button cannot be switched while the impact wrench is turning. To
switch the push button, stop the impact wrench, 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.
3. Change rotation speed
As shown in Fig. 10, 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.
CAUTION
In the work of the save mode (S), avoid the continuous screw-tightening as
temperature of electronic components of the converter switch increases.
4. Number of bolt tightened possible
Please refer to the table below for the number of bolt tightened possible
with one charge.
Bolt used
Hightension bolt M16 × 55 (F10T)
These values may vary slightly, according to surrounding temperature and
battery characteristics.
5. Using the hook
The hook is used to hang up the power tool to your waist belt while working.
CAUTION:
When using the hook, hang up the power tool firmly not to drop accidentally.
If the power tool is dropped, it may lead to an accident.
When carrying the power tool with hooked to your waist belt, do not fit any
bit to the tip of power tool. If the sharp bit such as drill is fitted to the power
tool when carrying it with hooked to your waist belt, you will be injured.
Install securely the hook. Unless the hook is securely installed, it may cause
an injury while using.

(1) Removing the hook.
Remove the screws fixing the hook with Philips screw driver. (Fig. 11)
(2) Replacing the hook and tightening the screws.
Install securely the hook in the groove of power tool and tighten the screws
to fix the hook firmly. (Fig. 12)
6. 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.
13) When releasing your finger from the remaining battery indicator switch,
the remaining battery indicator lamp goes off. The Table 6 shows the state of
remaining battery indicator lamp and the battery remaining power.
State of lamp 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.
As the remaining battery indicator shows somewhat differently depending
on ambient temperature and battery characteristics, read it as a reference.
NOTE:
Do not give a strong shock to the switch panel or break it.It may lead to a trouble.
To save the battery power consumption, the remaining battery indicator
lamp lights while pressing the remaining battery indicator switch.
7. How to use the LED light
Every time you press the light switch on the switch panel, the LED light
lights or goes off. (Fig. 14)
To prevent the battery power consumption, turn off the LED light frequently.
CAUTION:
Do not expose directly your eye to the light by looking into the light.
If your eye is continuously exposed to the light, your eye will be hurt.
NOTE:
To prevent the battery power consumption caused by forgetting to turn off
the LED light, the light goes off automatically in about 15 minutes.

OPERATIONAL CAUTIONS

1. Resting the unit after continuous work
After use for continuous bolt-tightening work, rest the unit for 15 minutes or
so when replacing the battery. The temperature of the motor, switch, etc.,
will rise if the work is started again immediately after battery replacement,
eventually resulting in burnout.
NOTE:
Do not touch the protector, as it gets very hot during continuous work.
2. Cautions on use of the speed control switch
This switch has a built-in, electronic circuit which steplessly varies the rotation
speed. Consequently, when the switch trigger is pulled only slightly (low speed
rotation) and the motor is stopped while continuously driving in screws, the
components of the electronic circuit parts may overheat and be damaged.
3. Tightening torque
Refer to Fig. 19 for the tightening torque of bolts (according to size), under the
conditions shown in Fig. 20. Please use this example as a general reference, as
tightening torque will vary according to tightening conditions.
NOTE:
If a long striking time is used, screws will be strongly tightened. This may
cause the screw to break, or may damage the tip of the bit.
If the unit is held at an angle to the screw being tightened, the head of the
screw may be damaged, or the specified torque may not be transmitted to
the screw. Always keep the unit and the screw being tightened in a straight
line.
