Key Features Efficient&Precise Cutting: The reinforced tungsten alloy cutting wheel with high hardness can ensure smooth and flat cutting without burrs, making the joints more beautiful to save decoration costs with an efficiency of 5-10 times higher than an electric cutting machine. Meanwhile, the embedded collimator with infrared positioning function and the precise guiding ruler with clear scale can facilitate high-precision cutting.  Thoughtful Design: The high-quality ball bearings allow for smooth rolling cuts. Also, the cutter wheel is highly visible, making it easy to observe the working process.  Good Stability: The large and thickened base and screw-reinforced handle ensure good stability, so you can use this product safely.  Sturdy and Durable: The tungsten alloy cutting wheel, aluminum alloy handle&bearing&base, and hardened alloy steel slide rail are wear-resistant, corrosion-resistant, and can resist shock, deformation.  Application It is suitable for cutting materials with a thickness within 3/5'' and width within 0.39-31'', such as wall tiles, groove tiles, raised tiles, patterned tiles, flat tiles, solid tiles, glazed tiles, polished tiles, glass tiles, and many other mainstream tiles. It can be used in multiple workshops and industrial sites.  How to Use 1. Fixed Position: Hold the handle with one hand, pull the slide back to the seat, and place the ceramic tile flat on the base plate (if necessary, extend the ruler to measure). Align the cutting line of the ceramic tile with the center support plate, and the front end of the ceramic tile should be close to the notch of the base plate. 2. Score and Press Down: Lower the handle and make the cutting wheel contact with the surface of the ceramic tile. Push the handle forward lightly to cut a continuous, even straight line on the ceramic tile. 3. Break-off: Lift the handle slightly backward, allowing the pressure block to fall smoothly onto the front end of the ceramic tile. Apply appropriate force to push the handle down, and the ceramic tile will break along the scoring line.

Please read the manual completely before installation and use, and pay particular attention to the safety instructions included.
