(3) Regarding recharging time

Depending on the combination of the charger and

batteries, the charging time will become as shown in

Table 3.

Table 3 Charging time (At 20°C)

(AC power supply / DC 12V (in-car) power

supply)

NOTE

The recharging time may vary according to the

ambient temperature and power source voltage.

Especially, using a DC 12V in-car power source may

require longer recharging time at high temperatures.

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.

4. Disconnect the charger’s power cord from the

receptacle or cigarette lighter socket

5. Hold the charger firmly and pull out the battery

NOTE

Be sure to pull out the battery from the charger after

use, and then keep it.

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.

CAUTION

⅜ If the battery is charged while it is heated because it

has been left for a long time in a location subject to

direct sunlight or because the battery has just been

used, the pilot lamp of the charger lights up green. In

such a case, first let the battery cool, then start

charging.

⅜ When the pilot lamp flickers in red (at 0.2-seconds

intervals), check for and take out any foreign objects

in the charger’s battery connector. If there are no

foreign objects, it is probable that the battery or

charger is malfunctioning. Take it to your authorized

Service Center.

⅜ Since the built-in micro computer takes about 3

seconds to confirm that the battery being charged

with UC18YML2 / UC18YRSL / UC18YFSL / UC18YGSL

is taken out, wait for a minimum of 3 seconds before

reinserting it to continue charging. If the battery is

reinserted within 3 seconds, the battery may not be

properly charged.

⅜ Check the voltage of the in-car power source when

the pilot lamp flickers in green (every 0.2 seconds)

continuously. (UC18YML2)

If the voltage is 12V or lower, it indicates that the car

battery has weakened and cannot be charged.

⅜ If the pilot lamp does not blink in red (every second)

even though the charger cord or cigarette lighter

connecting plug is connected to the power, it indicates

that the protection circuit of the charger may be

activated.

Remove the cord or plug from the power and then

connect it again after 30 seconds or so. If this does

not cause the pilot lamp to blink in red (every second),

please take the charger to the Hitachi 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

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.

(4) If you want to remove the bit, pull the guide sleeve

away from front of the tool.

CAUTION

If the guide sleeve does not return to its original

position, then the bit is not installed properly.

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. 6) (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.
