2. When replacing a fuse, always turn off the power switch and wait for the fuse to completely cool before replacing it.
3. If the contacts are aged or corroded, replace them promptly to avoid affecting fuse performance.
4. When installing the fuse, pay attention to the contact quality and ensure good contact between the contacts and the fuse core.
5. Do not attempt to repair a fuse while it is in operation. If a fault occurs, immediately shut down the machine for inspection.
