1. Keep work area clean. Cluttered areas and benches invite accidents.

2. Avoid dangerous environment. Don't expose power tools and charger to rain. Don't use power tools and charger in damp or wet locations. And keep work area well lit. Never use power tools and charger near flammable or explosive materials. Do not use tool and charger in presence of flammable liquids or gases.

3. Keep children away. All visitors should be kept safe distance from work area.

4. Store idle tools and charger. When not in use, tools and charger should be stored in dry, high or locked-up place — out of reach or children. Store tools and charger in a place in which the temperature is less than 40^ C.

5. Don't abuse cord. Never carry charger by cord or yank it to disconnect from receptacle. Keep cord from heat, oil and sharp edges.

6. When the charger is not in use or when being maintained and inspected, disconnect the power cord of the charger from the receptacle.

7. To avoid danger, always use only the specified charger.

8. Use only genuine HITACHI replacement parts.

9. Do not use power tools and charge for applications other than those specified in the Handling Instructions.

10. To avoid personal injury, use only the accessories or attachment recommended in these handling instructions or in the HITACHI catalog.

11. Let only the authorized service center do the repairing. The Manufacture will not be responsible for any damages or injuries caused by repair by the unauthorized persons or by mishandling of the tool.

12. To ensure the designed operational integrity of power tools and charger, do not remove installed covers or screws.

13. Always use the charger at the voltage specified on the nameplate.

14. Always charge the battery before use.

15. Never use a battery other than that specified. Do not connect a usual dry cell, a rechargeable battery other than that specified or a car battery to the power tool.

16. Do not use a transformer containing a booster.

17. Do not charge the battery from an engine electric generator or DC power supply.

18. Always charge indoors. Because the charger and battery heat slightly during charging, charge the battery in a place not exposed to direct sunlight; where the humidity is low and the ventilation good.

19. Use the exploded assembly drawing on this handling instructions only for authorized servicing.

PRECAUTIONS FOR CHARGER

1. Always charge the battery at an ambient temperature of 0–40°C. A temperature of less than 0°C will result in over charging which is dangerous. The battery cannot be charged at a temperature greater than 40°C.
   The most suitable temperature for charging is that of 20–25°C.
2. Do not use the charger continuously.
   When one charging is completed, leave the charger for about 15 minutes before the next charging of battery.
3. Do not allow foreign matter to enter the hole for connecting the rechargeable battery.
4. Never disassemble the rechargeable battery or charger.
5. Never short-circuit the rechargeable battery.
   Short-circuiting the battery will cause a great electric current and overheat. It results in burn or damage to the battery.
6. Do not dispose of the battery in fire.
   If the battery is burnt, it may explode.
7. Using an exhausted battery will damage the charger.
8. Bring the battery to the shop from which it was purchased as soon as the post-charging battery life becomes too short for practical use. Do not dispose of the exhausted battery.
9. Do not insert objects into the air ventilation slots of the charger.
   Inserting metal objects or flammable into the charger air ventilation slots will result in an electrical shock hazard or damage to the charger.

CHARGING

Before using the power tool, charge the battery as follows.

1. Connect the charger's power cord to the receptacle. When connecting the plug of the charger to a receptacle, the pilot lamp will blink in red. (At 1-second intervals).
2. Insert the battery into the charger. Firmly insert the battery into the charger till it contacts the bottom of the charger and checking the polarities as shown in Fig. 1.

CAUTION:

○If the batteries are inserted in the reverse direction, not only recharging will become impossible, but it may also cause problems in the charger such as a deformed recharging terminal.

3. Charging

When inserting a battery in the charger, the pilot lamp will light up continuously in red.

When the battery becomes fully recharged, the pilot lamp will blink in red. (At 1-second intervals.) (See Table 1)

(1) Pilot lamp indication

The indications of the pilot lamp will be as shown in Table 1, according to the condition of the charger or the rechargeable battery.

Indications of the pilot lamp
The pilot lamp lights or blinks in red.	Before Blinks charging for 0.5 seconds. Does not light continuously (off for 0.5 seconds)
	While charging	Lights Lights continuously
	Charging complete	Blinks Lights for 0.5 seconds. Does not light for 0.5 seconds. (off for 0.5 seconds)
	Charging impossible	Flickers Lights for 0.1 seconds. Does not light for 0.1 seconds. (off for 0.1 seconds)	Malfunction in the battery or the charger
The pilot lamp lights in green.	Charging impossible	Lights Lights continuously	The battery temperature is high, making recharging impossible.

(2) 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.

■: Ni-MH batteries
NOTE: The recharging time may vary according to the ambient temperature and the power supply voltage.

1. Disconnect the charger's power cord from the receptacle.
2. 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.

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.

(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

○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 (at 0.2-seconds 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 UC14YF2 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.

MAINTENANCE AND INSPECTION

1. Inspecting the mounting screws:

Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazard.

1. Cleaning of the charger

When the charger is stained, wipe with a soft dry cloth or a cloth moistened with soapy water. Do not use chloric solvents, gasoline or paint thinner, for they melt plastics.

1. Store idle charger

When not in use, the charger should be stored in dry, high or locked-up place — out of reach of children.

NOTE

Due to HITACHI's continuing program of research and development, the specifications herein are subject to change without prior notice.
