1. When the insulation handle is damaged, it cannot be used to cut live wires.
2. To ensure safety, the distance between hands and the metal part of the ground should not be less than 2cm.
3. The clamp head is relatively thin and has undergone heat treatment, so the clamp object should not be too large, and the force should not be too strong to prevent damage to the clamp head.
4. Pay attention to moisture prevention, and frequently add oil to the clamp shaft to prevent rusting.
