an abnormally high current. In this situation, release the Trigger Switch

Tool and Battery are overheated. In this situation, let the Tool and Battery
cool before pulling the Trigger Switch again.

tool will not operate. In this situation, remove and recharge the Battery.
Warning: To turn on the light, press the On/Off switch and make sure
