Model 385.1764180. How can I loosen tight hand wheel?
Be very careful if your machine is computerized as you don't want to get oil in the electronics. These instructions are for a Mechanical Machine only!
Revised--okay, if the needle mechanism is not moving, it needs oiling too. Open the top of your machine so you can see the mechanical insides. Gently and slowly wiggle the handwheel and watch what parts move where. Using good quality sewing machine oil (not 3-in-1, WD-40, cooking oil, or the old sewing machine oil from your grandmother's sewing box), drop ONLY one to two drops of oil each spot where metal moves against metal. Do NOT oil any metal Cams, belts, or plastic gears! Oil all the moving spots across your machine including the needle bar mechanism. (If possible, you will need to open the side cover to the left of the needle bar.) The needle bar needs to be able to move up and down and most likely it is stuck or it could be the take-up lever (the parts that look like knuckles that rotate round & round to move the needle bar). (WATCH Video Part 2 below, about 1 minute after the beginning.)
Look closely for oil ports (little round holes next to joints where things move) and apply a couple drops of oil in each port. (About 1.20 minutes into Video #2, you will briefly see an oil port on the top as she is rotating the take-up lever.) Those are the oil ports you will be looking for but they will be spread throughout your machine.
While you are at it, you might as well oil the moving parts in the bobbin area too. Most likely if the needle is stuck, parts in the bobbin area are also hanging up.
Now, to make the oil work faster, direct hot air from a handheld hairdryer at the mechanical interior of the machine. Get the metal warm to hot (don't get burned). Let it cool and try your machine. See if anything has loosened up. Are things moving better? If it is but the motor is still straining, you need to repeat the process until the sewing machine has a "happy" little sound.
IN THE FUTURE, clean and oil your machine every 8-10 hours of constant sewing or every six months if not in regular use. Doing some regular maintenance will keep your machine and you happy!
This is Part 1 (of 3 parts) of oiling a mechanical machine video that may help you. The machine is older than yours, but the idea is similar:

What exactly are you trying to accomplish? Is the handwheel difficult to turn (if it's a mechanical machine, it needs cleaning and oiling). This may help except you will need to concentrate of the handwheel mechanism:
Or is the handwheel not spinning freely because the belt is too tight?
Or are you unable to disengage the handwheel to wind a bobbin?
Here's a manual if you are need of one:
