Exposure to noise can cause hearing loss. Use auxiliary handle(s), if supplied with the tool. [. . . ] Use a bull point, cold chisel, scaling chisel, etc. 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. ⷠWhen changing from the g symbol mode to the m symbol mode, the action mode changing knob may no longer move in the symbol position. At this time, turn the tool on or turn the chuck by hand in the symbol position and then rotate the action mode changing knob. 15) Then make sure that the bit is securely held in place by turning it slightly. 16) Press the lock button on the grip base in the direction of arrow shown in the figure and with the lock button being pressed insert the depth gauge into the hex. 17) At this time, the depth gauge needs to be inserted so that its toothed side is directed to the toothed side of hex hole marking on the grip base as shown in Fig. Adjust the depth gauge to the desired depth by moving it back and forth while pressing the lock button. After the adjustment, release the lock button to lock the depth gauge. Inserting the depth gauge with its toothed side not directed to the toothed side of hex hole marking on the grip base as shown in the figure does not allow the depth gauge to be locked. 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. ⷠBits such as hole saw, which tend to pinch or catch easily in the hole, are not appropriate for this tool. This is because they 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. Use the dust cup to prevent dust from falling over the tool and on yourself when performing overhead drilling operations. The size of bits which the dust cup can be attached to is as follows. Bit diameter Dust cup 5 Dust cup 9 Install the side grip so that the protrusions on the grip fit in between the grooves on the tool barrel. Then tighten the grip by turning clockwise at the desired position. It may be swung 360° so as to be secured at any position. [. . . ] Never use "rotation with hammering" when the quick change drill chuck is installed on the tool. The quick change drill chuck may be damaged. In fact, this excessive pressure will only serve to damage the tip of your bit, decrease the tool performance and shorten the service life of the tool. Hold the tool firmly and exert care when the bit begins to break through the workpiece. [. . . ]
