1. Fuse protection A fuse is installed inside the Fuse knob, which is mainly used to protect the machine circuit. If the machine has an overload, short circuit or abnormal voltage, the fuse will automatically blow to prevent machine damage or safety accidents. 2. How to use the Fuse knob Under normal circumstances, there is no need to twist or replace it. If the machine suddenly fails to start or loses power, it may be that the fuse is blown. You can unscrew the Fuse knob, take out the fuse and check whether it is burnt out. Replacement method: Take out the damaged fuse and replace it with a new fuse of the same specification (usually the machine manual will provide the specification requirements of the fuse). 3. Maintenance of the fuse knob Avoid rotating the fuse knob at will when the power is on to avoid affecting the operation of the equipment. Check the power line regularly to ensure stable voltage and reduce the risk of fuse blowing.
