   Insert the battery into the battery charger as shown in Fig. 2. Make sure it contacts the bottom of the battery charger.
2. Insert the plug of battery charger into the receptacle.

WARNING: Do not use the electrical cord if damaged. Have it repaired immediately.

3. Charging

When the plug of battery charger has been inserted into the receptacle, charging will commence and the pilot lamp will light on.

NOTE: If the pilot lamp does not light, pull out the plug from the receptacle and check if the battery is properly mounted.

○In approx. one hour, when the battery is fully charged, the pilot lamp will go out.

NOTE: 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 four hour has passed after start of the charging, stop the charging and contact your HITACHI AUTHORIZED SERVICE CENTER.

1. Disconnect battery charger from the receptacle.

CAUTION:

Do not pull the plug out of the receptacle by pulling on the cord.

Make sure to grasp the plug when removing from receptacle to avoid damaging cord.

5. Remove the battery from the battery charger.

Supporting the battery charger with hand, pull out the battery from the battery charger.

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.

○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.

○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:

- When the battery charger has been continuously 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.

- If the battery is recharged when it is warm due to battery use or exposure to sunlight, the pilot lamp may not light.

The battery will not be recharged. In such a case, let the battery cool before charging.

- If the battery charger does not work while the battery is mounted correctly, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center.

BEFORE USE

Check the work area to make sure that it is clear of debris and clutter.

Clear the area of unnecessary personnel. Ensure that lighting and ventilation is adequate.

MAINTENANCE AND INSPECTION

CAUTION: Pull out battery before doing any inspection or maintenance.

1. Check the Mounting Screws

Loose mounting screws are dangerous. Regularly inspect them and make sure they are tight.

CAUTION: Using this battery charger with loosen, screws is extremely dangerous.

2. Check for Dust

Dust may be removed with a soft cloth or a cloth dampened with soapy water.

Do not use bleach, chlorine, gasoline or thinner, for they may damage the plastics.

3. Check the rotational direction

STORAGE

Storing in a place below 104^ F ( 40^ C) and out of the reach of children.
