Why is the hand wheel so tights
It shouldn't be too tight. Clean out and remove the bobbin/bobbin case. Now, try to turn it. Does it turn any better? If it does turn easily without the bobbin case and bobbin installed you know the bobbin case was out of adjustment.
To adjust the bobbin case reinstall the bobbin case. Slightly move the hand wheel back and forth. There should only be slight movement of the bobbin case. The bobbin case is held in place by a small piece of metal next to the bobbin case.on the lower right corner. Just make the adjustment to prevent the case from movement.
The hand wheel can also be prevented from movement due to the interior parts of the machine being filled with dried greese. If you're feel safe about this you can remove the front, back, etc and inspect for buildup. Clean it up with carburetor cleaner and a qtip. Try not to douse the plastic gears with this. Clean it thoroughtly. Put sewing machine oil on all steel against steel movement. Any plastic movement should be done with a non petrolium product like silican spray. You can move the hand wheel a great deal to observe any parts that may have movement probmems.
