[. . . ] 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. [. . . ] CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking function on the tool. 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. Do not short the battery cartridge: (1) Do not touch the terminals with any conductive material. Always switch off the tool before insertion or removal of the battery cartridge. To remove the battery cartridge, withdraw it from the tool while sliding the button on the front of the cartridge. To insert the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into place. 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. Be careful not to scratch the lens of lamp, or it may lower the illumination. Depress the reversing switch lever from the A side for clockwise rotation or from the B side for counterclockwise rotation. When the reversing switch lever is in the neutral position, the switch trigger cannot be pulled. 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. CAUTION: Before inserting the battery cartridge into the tool, always check to see that the switch trigger actuates properly and returns to the "OFF" position when released. If the tool consistently fails to quickly stop after switch trigger release, have tool serviced at a Makita service center. CAUTION: Do not look in the light or see the source of light directly. To change the speed, first switch off the tool and then slide the speed change lever to the "1" position for low speed, "2" position for medium speed or "3" position for high speed. Be sure that the speed change lever is set to the correct position before operation.
