When operating, the operator should pay attention to whether the accessories are intact, whether the insulated cable is damaged, whether there is aging, etc. After the inspection, plug in the power source before proceeding.2. During cutting and grinding operations, there should be no people and explosives within one meter around, and do not work in the direction of people to prevent casualties.3. After the grinding wheel is used up, when it needs to be replaced, the power supply must be cut off to replace it, in order to prevent accidental, pressing the switch, causing unnecessary personnel accidents.4. When working with dangerous and flammable materials, more than two fire extinguishers must be equipped to prevent problems. Achieve the principle of safety first and production second.5. After using for a long time of 30 minutes, you should stop resting for more than 20 minutes, and work after cooling down.
