| - | + | It is possible to make some other adjustments to the machine such as presser foot pressure and feed dog height which can have some benefits on specific applications. We ask that if you do not understand the benefits of these changes that the machine is left as it is currently set up. If you do have a specific need to change these, please make sure that the machine is returned to the way it is currently set up at the end of every session. Please refer to the manual for details. | |
