ENF002-1Power supplyThe tool should be connected only to a power supply ofthe same voltage as indicated on the nameplate, andcan only be operated on single-phase AC supply. Theyare double-insulated in accordance with EuropeanStandard and can, therefore, also be used from socketswithout earth wire.For Model HM0871C ENG102-3NoiseThe typical A-weighted noise level determined accordingto EN60745:Sound pressure level (LpA) : 86 dB(A)Sound power level (LWA) : 97 dB(A)Uncertainty (K) : 3 dB(A)Wear ear protection ENG216-2VibrationThe vibration total value (tri-axial vector sum)determined according to EN60745:Work mode : chiseling function with side handleVibration emission (ah,CHeq ) : 8.0 m/s2Uncertainty (K) : 1.5 m/s 2ENG306-1Work mode : chiseling function with side gripVibration emission (ah,CHeq ) : 8.0 m/s2Uncertainty (K) : 2.0 m/s 2For Model HM0870C ENG102-3NoiseThe typical A-weighted noise level determined accordingto EN60745:Sound pressure level (LpA) : 87 dB(A)Sound power level (LWA) : 98 dB(A)Uncertainty (K) : 3 dB(A)Wear ear protection ENG216-2VibrationThe vibration total value (tri-axial vector sum)determined according to EN60745:Work mode : chiseling function with side handleVibration emission (ah,CHeq ) : 11.0 m/s 2Uncertainty (K) : 1.5 m/s 2ENG306-1Work mode : chiseling function with side gripVibration emission (ah,CHeq ) : 11.5 m/s 2Uncertainty (K) : 1.5 m/s 2ENG901-1• The declared vibration emission value has beenmeasured in accordance with the standard testmethod and may be used for comparing one toolwith another.• The declared vibration emission value may also beused in a preliminary assessment of exposure.WARNING:• The vibration emission during actual use of thepower tool can differ from the declared emissionvalue depending on the ways in which the tool isused.• Be sure to identify safety measures to protect theoperator that are based on an estimation of
