If you are having a meat grinder in your kitchen, whether you are using a commercial or a non commercial model, you should be able to know the basics of trouble shooting your device when and if you run into any kind of problems.

Although commercial meat grinder of some time ago were simpler machines as they were not as complex due to the fact that they were manual and no electricity was involved. Although one of their main issue was the speed of work, since they were manual and involved using a handle to manually do the grind work the efficiency was a bit of a grey area. Regardless of that, even if you are using a state of the art machine which has the best ratings and top accessories, you could still expect problems every now and then and for that you should be ready to address them quickly and effectively.
One common problem people face is that the meat grinder does not turn ON. This could be due to two problems, if the meat grinder has a rechargeable battery, chances are the battery is not charging or it is dead. So replacing the battery may be the only solution. However, if the meat grinder takes direct power from the outlet, you need to inspect the cable to see if its damaged and needs to be replaced. Some cables also have fuses in the plug that goes off after some time and can be replaced easily.
