Note:
1. Do not cut the hard things, remember the safe operation is the first. Please take good protection measures.
2. Must secure the screw on the top before using it. As the electric mill is a high-speed operation tool, prevent yourself from getting cut.
3. When installed, the entire Mandrel Shank should be inserted to the end, as the electric grinding speed is pretty high, if you don't, the shaft will get bent soon or the cutting angle will be off from center.
4. At the same time, as far as possible use small diameter saw blade and low speed under the situation of meeting the usage requirements. Speed must not exceed 20,000 rpm.
5. In the selection of saw blade, the smaller your electric mill, choosing a smaller saw blade will be much stabler.
