1. Prepare Work Area: Clear your area of any items that may hinder your cutting of the quartzite tiles. Place the tile saw in a well-ventilated area as it produces dust.

2. Determine the Cut: Observe the quartzite tile and use a pencil to mark the cut line. Be precise as this determines how perfect your cut will be on the tile.

3. Install the Blade: Install a diamond blade on the tile saw. Ensure that the blade guard covers the top section of the blade and use a wrench to tighten the blade to the tile saw.

4. Put on Protective Gear: Wear personal protective gear, including a dust mask, gloves, and safety glasses before you begin cutting quartzite tile. The dust and tiny debris produced during the cutting process can be hazardous to inhale.

5. Cutting The Tile: Turn on the tile saw and lower the tile against the blade using both hands to apply even pressure across the tile. Make sure to follow the line you drew with the pencil, and go slowly to ensure accuracy. During the process, move your hands as far from the blade as possible to minimize the chances of injury.

6. Smooth The Edges: After cutting the quartzite tile, the edges may be rough, and you can smoothen them using sandpaper or a grinder.

7. Clean up: Remove the scraps from the saw and dust off the work area thoroughly with a brush.

Note: It is essential to use the correct blade for cutting quartzite tiles. An unsuitable blade could damage the tiles, produce unclean cuts, and even cause injury.
