[. . . ] Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury. [. . . ] Do not touch the drill bit or the workpiece immediately after operation; they may be extremely hot and could burn your skin. A battery short can cause a large current flow, overheating, possible burns and even a breakdown. Do not store the tool and battery cartridge in locations where the temperature may reach or exceed 50°C (122°F). Do not incinerate the battery cartridge even if it is severely damaged or is completely worn out. WARNING: MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury. Always stop tool operation and charge the battery cartridge when you notice less tool power. Charge the Nickel Metal Hydride battery cartridge when you do not use it for more than six months. ENC004-1 Before using battery cartridge, read all instructions and cautionary markings on (1) battery charger, (2) battery, and (3) product using battery. It may result in a risk of overheating, possible burns and even an explosion. If electrolyte gets into your eyes, rinse them out with clear water and seek medical attention right away. Always cover the battery terminals with the battery cover when the battery cartridge is not used. Do not short the battery cartridge: (1) Do not touch the terminals with any conductive material. CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking function on the tool. Always switch off the tool before insertion or removal of the battery cartridge. To remove the battery cartridge, withdraw it from the tool while pressing the buttons on both sides of the cartridge. To insert the battery cartridge, align the tongue on the battery cartridge with the groove in the housing Always insert it all the way until it locks in place with a little click. If not, it may accidentally fall out of the tool, causing injury to you or someone around you. If the cartridge does not slide in easily, it is not being inserted correctly. Use the reversing switch only after the tool comes to a complete stop. Changing the direction of rotation before the tool stops may damage the tool. When not operating the tool, always set the reversing switch lever to the neutral position. To change the speed, first switch off the tool and then slide the speed change lever to the "2" side for high speed or "1" side for low speed. [. . . ] There is a tremendous force exerted on the tool/bit at the time of hole break through. Hold the tool firmly and exert care when the bit begins to break through the workpiece. A stuck bit can be removed simply by setting the reversing switch to reverse rotation in order to back out. CAUTION: Adjust the adjusting ring to the proper torque level for your work. [. . . ]
