[. . . ] Vibration The vibration total value (tri-axial vector sum) determined according to EN60745-2-6: Work mode : hammer drilling into concrete, 10 mm diameter and 100 mm depth Vibration emission (ah, HD) : 20 m/s2 Uncertainty (K) : 1. For European countries only Noise The typical A-weighted noise level determined according to 60745-2-6: Sound pressure level (LpA) : 89 dB(A) Sound power level (LWA) : 100 dB(A) Uncertainty (K) : 3 dB(A) Wear ear protection DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to rotary hammer safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury. Hold power tools by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. [. . . ] 1 CAUTION: Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the "OFF" position when released. 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. For rotation with hammering, turn the knob so that the arrow on the knob points toward the symbol on the tool body. If you operate the tool with the knob positioned halfway between the mode symbols, the 2 CAUTION: Do not look in the light or see the source of light directly. Be careful not to scratch the lens of lamp, or it may lower the illumination. 8 For drilling in wood, metal or plastic materials, lock button and rotate the action mode changing knob to the symbol. Coat the bit shank head beforehand with a small amount of bit grease (about 0. 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. 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. Then make sure that the bit is securely held in place by turning it slightly. The torque limiter will actuate when a certain torque level is reached. CAUTION: As soon as the torque limiter actuates, switch off the tool immediately. Bits such as hole saw, which tend to pintch 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. The depth gauge cannot be used at the position where the depth gauge strikes against the gear housing. CAUTION: Always be sure that the tool is switched off and unplugged before carrying out any work on the tool. 17 Use the dust cup to prevent dust from falling over the tool and on yourself when performing overhead drilling operations. Dust cup 5 Dust cup 9 Install the side grip so that the teeth on the grip fit in between the protrusions on the tool barrel. CAUTION: Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations. [. . . ] 19 After drilling the hole, use the blow-out bulb to clean the dust out of the hole. Turn the tool on and apply slight pressure on the tool so that the tool will not bounce around, uncontrolled. When performing diamond core drilling operations, always set the change lever to the position to use "rotation only" action. CAUTION: If performing diamond core drilling operations using "rotation with hammering" action, the diamond core bit may be damaged. [. . . ]
