What are some tips for working with power tools? https://www.centralacwarehouse.com/ Switch all tools OFF before connecting them to a power supply. Disconnect and lockout the power supply before completing any maintenance work tasks or making adjustments. Ensure tools are properly grounded or double-insulated. The grounded equipment must have an approved 3-wire cord with a 3-prong plug. This plug should be plugged in a properly grounded 3-pole outlet. Test all tools for effective grounding with a continuity tester or a Ground Fault Circuit Interrupter (GFCI) before use. Do not bypass the on/off switch and operate the tools by connecting and disconnecting the power cord. Do not use electrical equipment in wet conditions or damp locations unless the equipment is connected to a GFCI. Do not clean tools with flammable or toxic solvents. Do not operate tools in an area containing explosive vapours or gases, unless they are intrinsically safe and only if you follow the manufacturer's guidelines.
