(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. Installing the bit (WH14DBDL / WH18DBDL)

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.

4. Selecting the socket matched to the bolt

(WR14DBDL / WR18DBDL)

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 (WR14DBDL / WR18DBDL)

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. 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. (See Fig. 7) (The

and

marks

are provided on the body.)

2. Switch operation

⅜ When the trigger switch is depressed, the tool rotates.

When the trigger is released, the tool stops.

⅜ The rotational speed of the drill 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.

NOTE

A buzzing noise is produced when the motor is about

to rotate. This is only a noise, not a machine failure.

3. Using the hook

The hook is used to hang up the power tool to your

waist belt while working.

CAUTION

⅜ 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.

⅜ 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.

⅜ 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. 8)

(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. 9)

4. 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.10)

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.
