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 short 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 been cooled for a while.

CAUTION

◯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.

◯When the pilot lamp flickers in red quickly (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.

◯Since the built-in micro computer takes about 3 seconds to confirm that the battery being charged with UC24YFA 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.

Before using the power tool, 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 (See Fig. 4) (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.

(1)Regarding the temperatures of the rechargeable battery The temperatures for rechargeable batteries are as shown in Table 4.

Approx. 50 min.

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.
