If the user has no experience with the car seat, he should follow the following safety measures when using it: low speed, slow speed, caution and other operations security. 2. The speed can be adjusted between 1500 and 7000 rpm, and the wood cutting speed should not exceed 4000. Higher speeds can be used for grinding. 3. The axis of the drill chuck, the axis of the wood and the center axis of the tailstock of the drill must be in a straight line, otherwise the nut must be adjusted. If it is not a cylinder, the speed must be reduced. 5. The tailstock bearing is not properly locked. When using a knife, lock the bottom of the screw and move it 1 to 1.5 centimeters away from the wood. If you really don't understand how it works, it's best to consult a professional.
