English * 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: 1,250 vatios = 10 amperios 125 voltios 9. Do not operate battery charger with damaged cord or plug-replace them immediately. 10. 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. 11. 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. 12. To reduce risk of electric shock, unplug charger from receptacle before attempting any maintenance or cleaning. Removing the battery will not reduce this risk. IMPORTANT SAFETY INSTRUCTIONS FOR USE OF THE BATTERY AND BATTERY CHARGER You must charge the battery before you can use the power tool. Before using the model UC18YRL battery charger, be sure to read all instructions and cautionary statements on it, the battery and in this manual. REMEMBER: USE ONLY HITACHI BATTERY TYPES EB7 SERIES, EB9 SERIES, EB12 SERIES, EB14 SERIES, EB18 SERIES, AND EBM1830. OTHER TYPES OF BATTERIES MAY BURST AND CAUSE INJURY! Follow these instructions to avoid the risk of injury: WARNING: Improper use of the battery or battery charger can lead to serious injury. To avoid these injuries: 1. NEVER 2. NEVER 3. NEVER 4. NEVER 5. NEVER 6. NEVER 7. NEVER disassemble the battery. incinerate the battery, even if it is damaged or is completely worn out. The battery can explode in a fire. short-circuit the battery. insert any objects into the battery charger's air vents. Electric shock or damage to the battery charger may result. charge outdoors. Keep the battery away from direct sunlight and use only where there is low humidity and good ventilation. charge when the temperature is below 32°F (0°C) or above 104°F (40°C). connect two battery chargers together. 8. NEVER insert foreign objects into the hole for the battery or the battery charger. 9. NEVER use a booster transformer when charging. 10. NEVER use an engine generator or DC power to charge. 11. NEVER store the battery or battery charger in places where the temperature may reach or exceed 104°F (40°C). 12. ALWAYS operate charger on standard household electrical power (120 volts). Using the charger on any other voltage may overheat and damage the charger. 13. ALWAYS wait at least 15 minutes between charges to avoid overheating the charger. 14. ALWAYS disconnect the power cord from its receptacle when the charger is not in use. CAUTION ON LITHIUM-ION BATTERY To extend the lifetime, the lithium-ion battery equips with the protection function to stop the output. In the cases of 1 and 2 described below, when using this product, even if you are pulling the switch, the motor may stop. This is not the trouble but the result of protection function. 1. When the battery power remaining runs out (The battery voltage drops to about 12V (G18DL) / about 8V (G14DL)), the motor stops. In such case, charge it up immediately. 2. If the tool is overloaded, the motor may stop. In this case, release the switch of tool and eliminate causes of overloading. After that, you can use it again. Furthermore, please heed the following warning and caution. WARNING In order to prevent any battery leakage, heat generation, smoke emission, explosion and ignition beforehand, please be sure to heed the following precautions. 1. Make sure that swarf and dust do not collect on the battery. ⅜ During work make sure that swarf and dust do not fall on the battery. ⅜ Make sure that any swarf and dust falling on the power tool during work do not collect on the battery. ⅜ Do not store an unused battery in a location exposed to swarf and dust. ⅜ Before storing a battery, remove any swarf and dust that may adhere to it and do not store it together with metal parts (screws, nails, etc.). 2. Do not pierce battery with a sharp object such as a nail, strike with a hammer, step on, throw or subject the battery to severe physical shock. 3. Do not use an apparently damaged or deformed battery. 7

8V (G14DL)), the motor stops.
In such case, charge it up immediately.
2.
If the tool is overloaded, the motor may stop. In
this case, release the switch of tool and eliminate
causes of overloading. After that, you can use it
