Once you select the right grinder under $200 for yourself and order it from homedepot.com, you must adhere to safety precautions before usage. The basic safeties include wearing a shield and gloves while using it. If it is a corded item, always take the power plug off before you move it about. However, if it is a cordless one, it is better to use the kill switch or take off the battery while moving it before or after use. Also, remember to always secure the surface you need to grind before you start the operation. Also, make everyone around you be with the knowledge that you are working with a dangerous tooling machine. It is better to work alone with someone knowing about your location and work process in case of an emergency.
Other safety tips to make your work environment safe, include de-cluttering your workspace – make sure that the floor where you’re working is free from scattered tools, timber, and power cables that could cause trips and falls. Proper lighting and adequate ventilation are also paramount to safe operation in your workshop.
Finally, never work around flammable material be it the use of a grinder, a saw or a sander. Also, have a fire extinguisher ready in your workspace if and when it is required. Avoid wearing loose clothing or use an apron to keep your clothes out of harm’s way. Some tasks are better off handled with different tools. For example for cutting bigger objects, you may want to look into and invest in one of the top ten home care tools that can save you money.
