[. . . ] it is also highly recommended that you wear a dust mask and thickly padded gloves. In cold weather or when the tool has not been used for a long time, let the tool warm up for a while by operating it under no load. Do not touch the bit or parts close to the bit immediately after operation; they may be extremely hot and could burn your skin. For model HR2450T/HR2450FT The quick change chuck for SDS-plus can be easily exchanged for the quick change drill chuck. [. . . ] 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. ⷠ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. The torque limiter will actuate when a certain torque level is reached. As soon as the torque limiter actuates, switch off the tool immediately. 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. Install the side grip so that the teeth on the grip fit in between the protrusions on the tool barrel. Coat the bit shank head beforehand with a small amount of bit grease (about 0. 11) After installing, always make sure that the bit is securely held in place by trying to pull it out. To remove the bit, pull the chuck cover down all the way and pull the bit out. Then make sure that the bit is securely held in place by turning it slightly.
