English ⅜ 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. Rechargeable batteries BCL1015 Table 2 Temperatures at which the battery can be recharged 32°F - 122°F (0°C - 50°C) ⅜ 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) 10.8 Battery capacity (Ah) 1.5 Ah BCL1015 40 min. NOTE: The recharging time may vary according to the ambient temperature and the power supply 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. 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.

How to make the batteries perform longer. ⅜ 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. ⅜ 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. Fig. 5 CAUTION: Be absolutely sure to keep the switch turned off and the battery removed to prevent any accident. (2) Push the lever in the direction of the arrow mark shown in Fig. 6 marked on the lever. (Fig. 6) Lever CAUTION: ● When the battery charger has been continuously used, the battery charger will be heated, thus constituting the cause of the failures. Once the Fig. 6 12
