1.When handling a granite block cutter, wear goggles and a dust mask. This will prevent granite dust from harming or irritating your eyes while you are cutting. If you work in a dusty place, wear a dust mask as well to keep your lungs clean.
If you're sensitive to loud noises, you may also need to wear earplugs or protection.
2.Tie up any loose hair and avoid wearing loose clothing. Before using a granite block cutter, remove all accessories, especially face and hand jewelry. Roll up your sleeves to expose your forearms to prevent any fabric from getting caught in the saw.
Measuring and Positioning the Cut
1.Use a tape measure or straightedge to plan your cut. Between the options, a straightedge is preferred because it can keep your line more even when you're ready to mark it. Position the tape measure or straightedge slightly to the left of the line you want so you can mark the line with tape later.
If you're cutting something that's square or rectangular, make sure the tape measure or straightedge makes a 90-degree angle with the side of the granite so your cut is precise.
2.Place a line of tape directly to the right of the tape measure or straightedge. Painter's tape or masking tape is ideal because it is easier to readjust. Apply it as close to the measuring tool as possible to keep your line straight and even.
3.Draw a straight line over the tape with a marker. This is the line your saw will follow as you make your cut. Use the measuring tool to keep the marker line straight as you draw it over the tape. If you mess up on the line, remove the tape, reapply a new strip, and start over.
Avoid drawing directly on the granite. If you make a mistake on the line, it will be harder to remove.
4.Use a diamond-cut blade to cut the granite. Granite is one of the most difficult rocks to cut because it is so hard. Most saw blades will not be equipped to cut granite without damaging them. Fit your saw with a diamond-cut blade for the sake of precision and safety.
