12 JCB-18BLDDInstruction & User ManualThe vibration emission value of the powertool is tested under EN 62841-1 and EN62841-2-11, and can vary during operationdepending on the following usage conditions:WARNING!m How the tool is used and the materialsbeing cut or drilled.m The tool being in good condition and wellmaintained.m Using the correct accessory for the tool andensuring it is sharp and in good condition.m The tightness of the grip on the handles andif any anti-vibration accessories are used.m The tool being used as intended by itsdesign and these instructions.m The declared vibration total value may alsobe used in a preliminary assessment ofexposure.THIS TOOL MAY CAUSE HAND-ARMVIBRATION SYNDROME IF USAGE ISNOT ADEQUATELY MANAGED.To be accurate, an estimation of exposurelevel in the actual conditions of use shouldalso take account of all parts of the operatingcycle. These include times when the tool isswitched off and when it is running idle butnot actually doing work. This may significantlyreduce the total exposure level over theworking period, helping to minimize yourvibration exposure risk.WARNING!m ALWAYS use sharp and undamaged bits,chisels, drills and blades.m Maintain this tool in accordance with theseinstructions and keep well lubricated (whereappropriate).m If the tool is to be used regularly then investin anti-vibration accessories.m Avoid using tools in temperatures of 10°Cor less.m Plan your work schedule to spread any highvibration tool use across a number of days.VIBRATION INFORMATIONVibration total values (triax vector sum) determined according to EN 62841-1 andEN 62841-2-11Drilling into Metal Vibration Emission Value (ah,D) 4.0 ms-2Uncertainty (K) 1.5 ms-2Screwdriving Vibration Emission Value (ah) 0.887 ms-2Uncertainty (K) 1.5 ms-2
