Slow-blow fuses are typically used where there is in an initial high current surge above the fuse rating (which is normally rated for average device current) when the device is first energized, such as a motor or power supply with a lot of filter capacitance, and you don't want the surge to blow the fuse.
For most other applications you want a fast-blow fuse.
 
If you use a slow blow fuse and overload it then the fire will be entertaining.
 
After carefully translating the online instructions. It says please use fast blow fuses and has a great recommendation on a local Chinese restaurant.
