13enExtension cable.If the use of an extension cordis required, its length and con-ductor cross-section must be adequate for theapplication in order to prevent a voltage dropin the extension cord, power loss and over-heating of the power tool. Otherwise, theextension cable and power tool are prone toelectrical danger, and the working efficiency isdecreased.Recommended dimensions of extensioncables at an operating voltage of 120 V –single-phase a. c., with only one power toolWSG8, WSG11, WSG12, WSG15 connected:WSG12, WSG15:WSG8, WSG11:Intended use of the power tool:Hand-guided angle grinder for dry grindingand cutting of metal and stone in weather-protected environments with the applicationtools and accessories recommended by FEIN.Operation of the power tool off powergenerators.This power tool is also suitable for usewith AC generators with sufficient poweroutput that correspond to the StandardISO 8528, design type G2. This Standard isparticularly not complied with when the so-called distortion factor exceeds 10 %. Whenin doubt, please refer to the generatorinstruction/specification guide.Operating the power tool offpower generators whose no-load speed exceeds the voltage value on thetype plate of the power tool is prohibited.WARNINGMax. cable length, ft Max. cable length, m≤ 100 100–200200–300≤ 30 30– 6060–100Min. conductor sizeA.W.G.Min. conductorcross-section, mm 216 14 12 1.5 2.5 4Max. cable length, ft Max. cable length, m≤ 100 100–200200–300≤ 30 30– 6060–100Min. conductor sizeA.W.G.Min. conductorcross-section, mm 218 16 14 1.0 1.5 2.5WARNINGOBJ_BUCH-0000000178-001.book Page 13 Tuesday, December 16, 2014 1:23 PM
