SAFETY

IMPORTANT SAFETY INSTRUCTIONS FOR BATTERY CHARGER

WARNING: Death or serious bodily injury could result from improper or unsafe use of battery chargers. To avoid these risks, follow these basic safety instructions:

READ ALL INSTRUCTIONS

1. This manual contains important safety and operating instructions for battery charger Model UC3SML.
2. Before using battery charger, read all instructions and cautionary markings on (1) battery charger, (2) battery, and (3) product using battery.
3. To reduce risk of injury, charge HITACHI rechargeable battery type EBM315. Other type of batteries may burst causing personal injury and damage.
4. Do not expose battery charger to rain or snow.
5. Use of an attachment not recommended or sold by the battery charger manufacturer may result in a risk of fire, electric shock, or injury to persons.
6. To reduce risk of damage to AC adapter or cigarette lighter and cord, pull by AC adapter or cigarette lighter when disconnecting battery charger.
7. Make sure cord is located so that it will not be stepped on, tripped over, or otherwise subjected to damage or stress.
8. An extension cord should not be used unless absolutely necessary. Use of improper extension cord could result in a risk of fire and electric shock.
   If extension cord must be used make sure:
   a. That blades of extension cord are the same number, size, and shape as those of plug on battery charger:
   b. That extension cord is properly wired and in good electrical condition; and
   c. That wire size is large enough for AC ampere rating of battery charger as specified in Table 1.

Table 1 RECOMMENDED MINIMUM AWG SIZE FOR EXTENTION CORDS FOR BATTERY CHARGERS

AC Input Rating Amperes* AWG Size of Cord
Equal to or but less Length of Cord, Feet (Meter) greater than than 25 (7.5) 50 (15) 100 (30) 150 (45)
0	2	18	18	18	16
2	3	18	18	16	14
3	4	18	18	16	14

* If the input rating of a battery charger is given in watts rather than in amperes, the corresponding ampere rating is to be determined by dividing the wattage rating by the voltage rating—for example:

$$ \frac {1 , 2 5 0 \text { watts }}{1 2 5 \text { volts }} = 1 0 \text { amperes } $$

1. Do not operate battery charger with damaged cord or AC adapter, cigarette lighter connector replace them immediately.
2. Do not operate battery charger if it has received a sharp blow, been dropped, or otherwise damaged in any way; take it to a qualified serviceman.
3. Do not disassemble battery charger; take it to a qualified serviceman when service or repair is required. Incorrect reassembly may result in a risk of electric shock or fire.
4. To reduce risk of electric shock, unplug charger from receptacle before attempting any maintenance or cleaning. Removing the battery will not reduce this risk.
5. This battery charger might be attached to HITACHI battery operated tools as a standard accessory. In this case, please confirm Instruction Manual of the HITACHI battery operated tools before using the battery charger.

Insert the cigarette lighter connecting plug into the cigarette lighter socket. If the plug is loose and falls out of the cigarette lighter socket, repair the socket. As the socket may be faulty, you are recommended to contact your local car dealer. Continued use of the socket may result in an accident due to overheating.

1. Insert the battery to the battery charger. Insert the battery into the battery charger as shown in Fig. 3.

4. Charging

When the battery is connected to the battery charger, 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.

○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.

○Regarding the temperature of the rechargeable battery. The temperatures for rechargeable batteries are as shown in the table below, and batteries that have become hot should be cooled for a while before being recharged.

Table 2

Rechargeable batteries	Temperature at which the battery can be recharged
EBM315	32°F — 122°F (0°C — 50°C)

○Regarding recharging time

Table 3 shows the recharging time required according to the type of battery.

Table 3 Recharging time (approx. min.) at 20°C

Battery voltage (V)	Battery capacity (Ah)
	1.5 Ah
3.6 EBM	315 60 min.

NOTE: The recharging time may vary according to the ambient temperature and the power supply voltage.

1. Disconnect battery charger from the receptacle or cigarette lighter socket.

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.

1. Remove the battery from the battery charger.

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

Do not leave the battery charger or battery in the car.

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 Screws

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

⚠️ CAUTION: Using this battery charger with loosened screws is extremely dangerous.

1. 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.

1. Fuse replacement of cigarette lighter connecting plug

CAUTION:

For continued protection against risk of fire, replace only with same type and ratings of fuse in cigarette lighter connecting plug.

250V, 6A, DC
