We recommend the following personal protective equipment when you use our diamond cup grinding wheel:   Important note: 1. Never remove the machine's protective cover and make sure it is properly adjusted to keep debris away from you. 2. Make sure that no one else is in danger, especially near the machine while working.  We got the job done switching back and forth and letting our grinder cool off every now and then and it took us just three hours!!! Couldn't be more happier with these!!! I have a whole another pad to do and couldn't have worked out better getting these! My husband and I are working on updating our front porch! Easter weekend plans - No one we knew had the tools needed to grind down the cement pad to repaint it properly! Looked at the tool rental department of the big box store and would have easily cost 150+ to rent what we needed. And then.. I thought. CHECK AMAZON! And I did. These were the first go to and I purchased two for safe measure! \"I wanted to get my front porch back to bare concrete so I can stain it VS paint. This is slow but is working great and with half of my porch done, there's still plenty of blade left to finish. It doesn't fit centered initially but with the locking washer it holds just fine and for me has been centered. Do be careful as you can easily gouge the concrete if not careful. I found that using circular anti clockwise motions worked best. Just don't hold it in one spot and it works beautifully.\"  It was very easy to maintain the exterior corners of the steps but I was unable to grind the inside of the stress\/crack relief grooves. All in all, this diamond wheel easily attached to my 4” grinder and preformed better then I had anticipated Very impressed with the diamond wheel. I thought I would need to buy more to finish the patio but there is plenty of material remaining on the wheel. It took approximately ~8 hours to grind the paint off of the patio with measurements of 11’ X 16’. The end results is a smoother concrete finish then the “broom” finish of the unpainted surfaces. The final concrete is closer to a steel finish found in warehouse floors. 1. Strictly follow the instructions in the machine manual. 2. Do not install a diamond dish\/cup wheel that is too loose or too tight on the flange. 3. Tighten only with the tool provided with the machine. 4. Be sure to hold the concrete grinding wheel properly to prevent slipping, but do not use excessive force. Never use a hammer. 5. Keep flanges and threads clean without burrs and rust. 6. Before installing the diamond grinder wheel, please replace the deformed or damaged flange.
