Before start cutting, you must identify the exact location of cuts, where to start, and where to stop the cut. As a rule, you may start it from the center of column lines.
Following steps should be followed while cutting through the concrete:
Step 1: Chose the type of blade you want to go with. You can have either dry cutting diamond or wet cutting diamond.
Step 2: Prepare the workstation to avoid any dust going around and making everything dirty. For example, if you are working in a basement, close all the windows. If you are working in an open space, put some temporary wall shields to protect the environment. You should also be wearing a dust mask, knee pads, steel-toed boots, and protection on your eyes. Put safety signs around to let others know about the criticality of work.
Step 3: Mark the concrete with a chalk line. The line should be solid enough so that when you are cutting the concrete, it does not disappear due to water being run on top of it
Step 4: Get a constant supply of water. It will not only be needed for cutting but also for removing dust.
Step 5: Check the blade depth, when the saw is off. You can do it with a knob or find it from the manual.
Step 6: Turn on the saw. Make a one-inch cut. Doing a sequence of light cuts is safer.
Step 7: Remove the saw from the concrete and allow it to spin freely for some time to remove dust from it. It will also cool down the blade.
Step 8: Put the blade again in the cut and repeat steps 6 and 7, until you have reached the desired depth in the concrete.
Step 9: Regularly remove the dust. Even if you are using water, you still may need a vacuum to suck the dust.
Step 10: Use the claw hammer and mason chisel on the cut surface. It will allow you to have a cleaner edge(4 kinds method clean concrete). The smashed concrete should be moved away from the site, either to a yard as fill or discard in a landfill
