Before using the impact driver or impact wrench, charge

the battery as follows.

1. Connect the charger power cord to the receptacle

Connecting the power cord will turn on the charger.

2. Insert the battery into the charger

Insert the battery firmly while observing its direction,

until it contacts the bottom of the charger (the pilot

lamp lights up).

CAUTION

If the pilot lamp does not light up, pull out the

power cord from the receptacle and check the

battery mounting condition.

About 50 minutes is required to fully charge the

battery at a temperature of about 20°C. 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 power cord from the

receptacle

4. Hold the charger tight and pull out the battery

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 (Impact driver)

Always follow the following procedure to install driver

bit (Fig. 2).

(1) Pull the guide sleeve 7 away from front of the tool.

(2) Insert the bit 9 into the hexagonal hole in the anvil 8.

(3) Release the guide sleeve 7 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 matched to the bolt

(Impact wrench)

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 (Impact wrench)

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 (Fig. 3)

Align the plunger located in the square part of the

anvil B with the hole in the hex. socket 0. Then push

the plunger, and mount the hex. socket 0 on the anvil

B. Check that the plunger is fully engaged in the hole.

When removing the socket 0, 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

CAUTION on lithium-ion battery

To extend the lifetime, the lithium-ion battery equips

with the protection function to stop the output. Therefore,

if the tool is overloaded, the motor may stop. However,

this is not the trouble but the result of protection function.

In this case, release the switch of tool and eliminate the

causes of overloading.

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.
