3. DESCRIPTION OF PRODUCTS3-001 Dust and noise emission valuesNoiseMeasuring ConditionsThe noise emission to EN 31202 as amended by TC 142 determine correlatives in order to achieve a gradebetter than 3dB (decibels).Emission values from the workplace = …… dB(A) when idlingEmission values from the workplace = 77.8 dB(A) when drillingMeasurement uncertainty constants K are 4.0 dB/AThe machine’s specified settings during the measuring cycle:Drill 1 hinge cup drill bit Ø 35 mm t = 13 mm n = 2890 rpm2 dowel drill bits Ø 8 mm t = 13 mm n = 2940 rpmworkpieceuncoated particle boardMicrophone’s position: 0.5 meter in front of the drill motor axle at 1.5 meter heightDust:The determined dust ratings, according to DIN 33893, Part 2, are:Statistically proven maximum amount ........ mg/m 3Description of the interfacing exhaust connection piece:Suction exhaust pipeMean air speedStatic suctionØ 100 mm20 m/sec920 PaConnection of the exhaust system:The Multipress must be connected to a vacuum suction system as described in the instructions.The connecting lines must be flame-resistant.If an electric coupling is required for the vacuum system, Grass has a special accessory available – a volumeflow monitor with the appropriate contacts which are connected as shown in the electrical wiring diagram insection 4-007.Suction vacuuming elementsIf the dust and shavings collection elements of the Multipress are operated correctly (hook up as described),the amount of wood dust falls well below the TRK specified requirements. Test certificates relating to dustmeasurements performed to DIN 33893, Part 2, by an independent agency are available on request.14The star in your cabinet
