4. Selecting the socket matched to the bolt

(WR12DAF2)

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.

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 (WR12DAF2)

Select the socket to be used.

ⅷ Pin, O-ring type (Fig. 6 and 7)

(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 (Fig. 8)

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.

HOW TO USE

CAUTION:

⅜ When using the light equipped hook, pay sufficient

attention so that the main equipment does not fall. If

the tool falls, there is a risk of accident.

⅜ Do not attach the tip tool except phillips bit to the tool

main unit when carrying the tool main unit with the

light equipped hook suspended from a waist belt.

Injury may result if you carry the equipment

suspended from the waist belt with sharp tipped

components such as drill bit attached.

1. Using the light equipped hook

The light equipped hook can be installed on the right

or left side and the angle can be adjusted in 5 steps

between 0° and 80°.

(1) Operating the hook

(a) Pull out the hook toward you in the direction of

arrow (A) and turn in the direction of arrow (B).

(Fig. 9)

(b) The angle can be adjusted in 5 steps (0°, 20°, 40°,

60°, 80°).

Adjust the angle of the hook to the desired position

for use.

(2) Switching the hook position

CAUTION:

Incomplete installation of the hook may result in

bodily injury when used.

(a) Securely hold the main unit and remove the screw

using a slotted head screwdriver or a coin. (Fig.

10)

(b) Remove the hook and spring. (Fig. 11)

securely fasten with screw. (Fig. 12)

⅜ The pilot lamp goes off to indicate that the battery is

fully charged.

The battery charging time becomes longer when a

temperature is low or the voltage of the power source

is too low.

When the pilot lamp does not go off even if more

than 120 minutes have elapsed after starting of the

charging, stop the charging and contact your HITACHI

AUTHORIZED SERVICE CENTER.

CAUTION

If the battery is heated due to direct sunlight, etc.,

just after operation, the charger pilot lamp may

not light up. At that time, cool the battery first,

then start charging.

3. Disconnect the charger’s power cord from the

receptacle

4. Hold the charger firmly and pull out the battery

NOTE

After charging, 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.

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 (WH12DAF2)

Always follow the following procedure to install driver

bit. (Fig. 5)

(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.
