Make sure that hand is not near the mechanism/belt on the right of the sewing machine. Do not underestimate the weight of the sewing machine. Make sure that the machine is resting completely on the wooden peg before removing your support. When putting the machine back into position, make sure that you can handle the weight and lower it slowly. You should never let it drop. Keep hands in lap while winding the bobbin so that they cannot be caught in the moving parts of the machine.
