Notes:1. Please pay attention to whether the size is suitable for your machine.2. Be sure to tighten the screw and make sure the disc rotates properly before use.3. When using the diamond cutting wheel, the bolts on the mandrels should be tightened, and the speed of the electric grinder should not be too fast. Please take safety measures.4. When using HSS circular saws, the rotational speed should be slow and the blades should be inserted into the end of the mandrels. Since the center of gravity of the front end is much heavier, at high speeds, inertia will change the course! Therefore, the pins should be clamped in place. The speed must be controlled within 20,000 rpm. Do not press hard cut on hard things.5. When using resin, cut off the discs, please insert the discs into the end of the mandrels as much as possible, and the rotation speed should not be too fast, so as not to cause a broken rod and a curved rod. Try to keep the discs perpendicular to the objects to be cut while cutting. It can become very hot when cutting, add a little water to keep cool.6. Remember that safe surgery comes first! Please take good protection.7. Due to the difference between different monitors, the pictures may not reflect the actual color of the item.8.
