[. . . ] Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to safety 4 Always be sure you have a firm footing. 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 rotation with hammering, turn the knob so that the arrow on the knob points toward the symbol on the tool body. [. . . ] 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. Coat the bit shank head beforehand with a small amount of bit grease (about 0. ⷠ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. 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. The depth gauge cannot be used at the position where the depth gauge strikes against the gear housing. Select one of the two modes suitable for your work needs by using this knob. For rotation only, turn the knob so that the arrow on the knob points toward the symbol on the tool body. Use the dust cup to prevent dust from falling over the tool and on yourself when performing overhead drilling operations. 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 a 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. Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations. failure to do so may result in the loss of control of the tool and potentially severe injury. NOTE: Eccentricity in the bit rotation may occur while operating the tool with no load. 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. [. . . ] Never use "rotation with hammering" when the drill chuck assembly is installed on the tool. Noise ENG102-3 The typical A-weighted noise level determined according to EN60745: Sound pressure level (LpA): 89 dB (A) Sound power level (LWA): 100 dB (A) Uncertainty (K): 3 dB (A) Wear ear protection. ENG217-2 Vibration The vibration total value (tri-axial vector sum) determined according to EN60745: Work mode: hammer drilling into concrete Vibration emission (ah, HD): 15. The declared vibration emission value has been measured in accordance with the standard test method and may be used for comparing one tool with another. [. . . ]
