Yes, it is possible to use a mixer grinder without keeping your hands on the lid as long as it is placed correctly. However, make sure that you do not put too much food in the jar. If the lid doesn’t work properly, then you need to hold it with your hand, or else it will throw out all the food when you switch it on. Closing the lid properly is also important as the machine can spill the food out when it vibrates in the starting.
