[. . . ] Grasp the change cover of the drill chuck assembly and set the line to the symbol. Place the drill chuck assembly on the spindle of the tool. Grasp the change cover of the drill chuck assembly and turn the change cover line to the symbol until a click can clearly be heard. 8) CAUTION: Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released. To start the tool, simply pull the switch trigger. Tool speed is increased by increasing pressure on the switch trigger. For continuous operation, pull the switch trigger and then push in the lock button. To stop the tool from the locked position, pull the switch trigger fully, then release it. 8) For model HR2450F, HR2450FT CAUTION: 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. , depress the lock button and rotate the action mode changing knob to the H symbol. 13) For chipping, scaling or demolition operations, depress the lock button and rotate the action mode changing knob to the g symbol. Use a bull point, cold chisel, scaling chisel, etc. 14) For drilling in wood, metal or plastic materials, depress the lock button and rotate the action mode changing knob to the m symbol. CAUTION: • Do not rotate the action mode changing knob when the tool is running under load. € To avoid rapid wear on the mode change mechanism, be sure that the action mode changing knob is always positively located in one of the three action mode positions. 7 Torque limiter The torque limiter will actuate when a certain torque level is reached. The motor will disengage from the output shaft. When this happens, the bit will stop turning. CAUTION: • As soon as the torque limiter actuates, switch off the tool immediately. This will help prevent premature wear of the tool. [. . . ] 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 breakthrough, when the hole becomes clogged with chips and particles, or when striking reinforcing rods embedded in the concrete.
