| 32 |EN• Inform and consult the responsiblestructural engineer, architect or theresponsible site engineer about planneddrilling.Cut through reinforcement only with the approvalof a structural engineer.• Before drilling holes drilling objects, checkthe rooms concerned for obstructions andblock off this area. Use formwork to securethe drill core against falling.• Dust from materials such as coatingscontaining lead, several types of wood,minerals and metals can be harmfulto health and cause allergic reactions,respiratory diseases and/or cancer.Asbestos-containing material may only bemachined by specialists.f Where possible use dust extraction suitablefor the material.f Ensure the workplace is properly ventilated.f We recommend wearing a face maskrespirator with filter class P2 or P3(to EN 149:2001).Observe the relevant regulations in your countryfor the materials to be machined.2.6.3 Electrical safety• The power tool may only be used forwet drilling if operated with a perfectlyfunctioning PRCD personal protectionswitch (see page 38).• Check the power tool, connection cable andplug for damage before each use.A damaged machine is dangerous and no longersafety to operate.• Note the mains voltage! The power sourcevoltage must match the details given on therating plate of the power tool.• If using the power tool with mobilegenerators, loss of power or atypicalbehaviour on switching on is possible.• Do not use the power tool if the cable isdamaged. Do not touch the damaged cableand disconnect the mains plug if the cable isdamaged while you are working.Damaged cables increase the risk of an electricshock.• Only use extension cables suitable for themachine's power consumption and whichhave a minimum core cross-section of1.5 mm 2 . If you use a cable drum, alwayscompletely unwind the cable.The rolled up cable can heat up and start toburn.• Regularly clean the ventilation slots of yourpower tool by blowing it out. Never useliquids. Never insert screwdrivers or anyother objects into the ventilation slits. Donot cover the ventilation slits.The motor fan draws dust into the housing anda large accumulation of metal dust can causeelectrical hazards.• External electromagnetic interference (e.g.mains voltage fluctuations, electrostaticdischarges) can cause the power tool toswitch off automatically.In this case, switch off the power tool and thenswitch it back on again.• Before use, check all water-carrying parts– including those of the accessories – forperfect working order and leaks.Leaking water increases the risk of an electricshock.2.6.4 Safety of people• Wear personal protective equipment and,depending on the work situation, use:Full-face protection, eye protectionor safety glasses/goggles, hard hatand special apronProtect yourself against debris thrownup by wearing a hard hat, safetygoggles or face protection and wear anapron, if necessary.Hearing protectionThe typical A-weighted soundpressure level of this power tool is over85 dB (A) while working with the tool.If you are exposed to loud noise forlengthy periods, there is a risk ofhearing damage or even hearing loss.Anti-vibration safety glovesAt a release value A (8) for arm-handvibrations of over 2.5 m/s 2 , the wearingof anti-vibration safety gloves isrecommended.Non-slip safety footwear
