1. Insert the plug of battery charger into the receptacle. Battery When the plug of battery charger has been inserted into the receptacle, pilot lamp will Battery blink in red. (At 1-second intervals) installation hole WARNING: Pilot lamp Do not use the electrical cord if damaged. Have it repaired immediately. Fig. 4 Fig. 3 English 2. Insert the battery to the battery charger. Insert the battery into the battery charger as shown in Fig. 4. Make sure it contacts the bottom of the battery charger. 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 the battery is connected to the battery charger, charging will commence and the pilot lamp will light in red. (See Table 2) NOTE:If the pilot lamp flikers in red, 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 blink in red slowly. (At 1-second intervals) (See Table 2) (1) Pilot lamp indication The indications of the pilot lamp will be as shown in Table 2, according to the condition of the charger or the rechargeable battery. Table 2 Indications of the pilot lamp Before charging Blinks (RED) Lights for 0.5 seconds. Does not light for 0.5 seconds. (off for 0.5 seconds) While charging Lights (RED) Lights continuously Charging complete Blinks (RED) Lights for 0.5 seconds. Does not light for 0.5 seconds. (off for 0.5 seconds) Charging impossible Flikers (RED) Lights for 0.1 seconds. Does not light for 0.1 seconds. (off for 0.1 seconds) Malfunction in the battery or the charger Charging impossible Lights (GREEN) 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. Table 3 Recharging of batteries that have become hot Rechargeable batteries Temperatures at which the battery can be recharged EB14B 23°F—140°F (–5°C—60°C) English (3) Regarding recharging time (At 68°F (20°C)) In approx. 60 minutes. NOTE:The charging time may vary according to temperature and power source voltage. 4. Disconnect battery charger from the receptacle. 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. 5. Remove the battery from the battery charger. Supporting the battery charger with hand, pull out the battery from the battery charger. CAUTION: . When the battery charger has been continuosly 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 rechraged when it is warm due to battery use or exposure to sunlight, the pilot lamp may light in green. The battery will not be recharged. In such a case, let the battery cool before charging. . When the pilot lamp flikers rapidly in red (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 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. 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. English 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. OPERATION 1. Using the light equippe...
