User manual MAKITA BDF452

[. . . ] 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. [. . . ] 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. 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 side 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 you can see the red part on the upper side of the button, it is not locked completely. 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. 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. 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. If the tool consistently fails to quickly stop after switch trigger release, have tool serviced at a Makita service center. [. . . ] Make sure that the carbon brush caps have fit into the holes in brush holders securely. After replacing brushes, insert the battery cartridge into the tool and break in brushes by running tool with no load for about 1 minute. Then check the tool while running and electric brake operation when releasing the switch trigger. If electric brake is not working well, ask your local Makita service center for repair. [. . . ]
