User manual MAKITA HR2450FT

[. . . ] Use auxiliary handle(s), if supplied with the tool. Hold power tools by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock. Wear a hard hat (safety helmet), safety glasses and/or face shield. [. . . ] Do not look in the light or see the source of light directly. nOTE: · Use a dry cloth to wipe the dirt off the lens of lamp. Be careful not to scratch the lens of lamp, or it may lower the illumination. Always check the direction of rotation before operation. ⷠ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 you operate the tool in counterclockwise rotation, the switch trigger is pulled only halfway and the tool runs at half speed. For counterclockwise rotation, you cannot push in the lock button. The torque limiter will actuate when a certain torque level is reached. As soon as the torque limiter actuates, switch off the tool immediately. This will help prevent premature wear of the tool. ⷠHole saws cannot be used with this tool. They tend to pinch or catch easily in the hole. This will cause the torque limiter to actuate too frequently. Always be sure that the tool is switched off and unplugged before carrying out any work on the tool. Keep the tool in position and prevent it from slipping away from the hole. Do not apply more pressure when the hole becomes clogged with chips or particles. Instead, run the tool at an idle, then remove the bit partially from the hole. By repeating this several times, the hole will be cleaned out and normal drilling may be resumed. cAUTION: · There is tremendous and sudden twisting force exerted on the tool/bit at the time of hole break-through, when the hole becomes clogged with chips and particles, or when striking reinforcing rods embedded in the concrete. Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations. Eccentricity in the bit rotation may occur while operating the tool with no load. [. . . ] The use of any other accessories or attachments might present a risk of injury to persons. Only use accessory or attachment for its stated purpose. If you need any assistance for more details regarding these accessories, ask your local Makita Service Center.
