Good point BUT the key is prevention! I'm not saying this is the case here. But, I always stress to people when they buy one from us is to make sure to hold onto the needle thread when you start sewing. IDK how many jams it can take to break, it causes a lot of stress on the driver. So if your machine ever jams DO NOT try to use the motor to power through it, they are strong enough esp with the reducer to make this happen. Shut the motor off & turn the wheel backwards. If you can't turn the machine take the hook & race out to unclog it.
