English GENERAL OPERATIONAL PRECAUTIONS 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 fl ammable or explosive materials. Do not use tool and charger in presence of fl ammable liquids or gases. 3. This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance. 4. Store idle tools and charger. When not in use, tools and charger should be stored in dry, high or lockedup 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 specifi ed charger. 8. Use only genuine HITACHI replacement parts. 9. Do not use power tools and charger for applications other than those specifi ed 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. If the supply cord is damaged, it must be replaced by the manufacture or its service agent or a similarly qualifi ed person in order to avoid a hazard. 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 specifi ed on the nameplate. 14. Always charge the battery before use. 15. Never use a battery other than that specifi ed. Do not connect a usual dry cell, a rechargeable battery other than that specifi ed or a car battery to the power tool. 16. Do not use a transformer containing a booster. 17. Do not charge the battery from 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 is 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 -10 40 C. A temperature of less than -10 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 fi re. 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 fl ammable into the charger air ventilation slots will result in an electrical shock hazard or damage to the charger. SYMBOLS WARNING The following show symbols used for the machine. Be sure that you understand their meaning before use. Read all safety warnings and all instructions.

English 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 charge indicator lamp will blink in red (At 1-second intervals). 2. Insert the battery into the charger. Firmly insert the battery into the charger as shown in Fig. 1. Table 1 Indications of the charge indicator lamp 3. Charging When inserting a battery in the charger, the charge indicator lamp will blink in blue. When the battery becomes fully recharged, the charge indicator lamp will light up in green. (See Table 1) (1) Charge indicator lamp indication The indications of the charge indicator lamp will be as shown in Table 1, according to the condition of the charger or the rechargeable battery. Before charging Blinks (RED) Lights for 0.5 seconds. Does not light for 0.5 seconds. (off for 0.5 seconds) Plugged into power source Blinks (BLUE) Lights for 0.5 seconds. Does not light for 1 second.

English 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 fi rst 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 charge indicator lamp of the charger lights for 0.3 seconds, does not light for 0.3 seconds (off for 0.3 seconds). In such a case, fi rst let the battery cool, then start charging. When the charge indicator lamp fl ickers (at 0.2-second intervals), check for and take out any foreign objects in the charger s battery connector. 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 confi rm that the battery being charged with UC18YSL3 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. NOTE Due to HITACHI s continuing program of research and development, the specifi cations herein are subject to change without prior notice. 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. 2. 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. 3. Store idle charger When not in use, the charger should be stored in dry, high or locked-up place out of reach of children. CAUTION In the operation and maintenance of power tools, the safety regulations and standards prescribed in each country must be observed. 5
