Hand-held power tools are portable power tools, a wide range of applications. Handheld electric tool move sex, vibration is larger, prone to leakage and other faults. Due to such tools often used in hand clenched again, once the shell charged, current through the body and dangerous electric shock consequences, so in the management, use, inspection, maintenance should be given special attention. So how to prevent hand electric tools accident? Below small make up detailed introduction for you. , general choose Ⅱ hand-held power tools, and furnish the rated current action is not more than mA, rated leakage action time is less than. S of the leakage protector. If using Ⅰ class hand-held electric tools must also do protection by zero. Operators must wear insulating gloves, wear insulated shoes, or standing on the insulating mat. , hand-held electric tools before use, must go through acceptance of construction safety management department, determine requirements, inspection procedures to apply certificate or have to use. Hang qualified brand equipment. And narrow place (Boiler, metal containers, cooking, pipe, etc. ), appropriate chooses isolation transformer Ⅲ hand-held power tools; If choose Ⅱ hand-held power tools, must be put fortification splash of leakage protector, the isolation transformer or leakage protector installed in a narrow place outside, they should work. , in the open air, wet places, or on the metal frame, must choose Ⅱ hand-held power tools, and leakage protector of fortification splash. It is forbidden to use Ⅰ hand-held power tools. , work, and may not touch cutting, mould and grinding wheel, found that the grinding blunt, damage, should immediately stop the repair or replacement, and then continue work. , using the grinding wheel machine, check the grinding wheel and the cushion between flange and install solid, nuts may not be too tight, all be affected with damp be affected with damp, deformation, crack, broken, ke edge gap or come into contact with oil, grinding wheel base class shall be used, and shall not be affected with damp be affected with damp grinding wheel piece to drying. , hand-held electric tools complex line must use climatic type rubber sheathed copper soft cable resistance, and can not have joint, banning the use of plastic yarn. Should pay attention to the sound, it is forbidden to use, overload operation and the temperature rise, abnormal should immediately stop check. In the work time is too long, the temperature rise of the machines more than ℃, should stop, after natural cooling, homework all right again. , electric tools in use shall not arbitrarily change the plug, and will lead directly inserted into the socket, when electric tools don't work or need to change the head, immediately remove the plug, but we can not pull the power cord to remove the plug. Plug, switch should be in the off position, in case of sudden starting.
