Does anyone have this machine??

It is from the early 80's I think. It is/was my mothers and she has given it to me...apparently to "fix".

I really need a manual and wanted to see if anyone had this machine/manual and would be willing to share? Pretty please

I know it FOR SURE needs some oiling/general maintenance done and I really don't want to pay for something I could do myself; if I knew how to that is. This machine probably has not been fired up in 10 years or longer.

Thanks in advance if your able to help!!!

A picture would be very helpful. Many of the department store branded machines were manufactured by sewing machine makers who also made machines with their own names and for other companies, so even if no one has your particular machine, they may have a sibling machine. Even a cousin machine can be helpful in terms of oiling, threading, etc.

sewUSA has one for a JC Penney 6935 which is very similar to yours. Hope this will help.

These people claim to have a manual for the machine.

Frankly, this looks like a typical Japanese machine from the era. If you're comfortable with your skills, skip the manual for now and try my steps. ("Oil" means "sewing machine oil" and nothing else. You can get it pretty much anywhere that sells more sewing stuff than an emergency sewing kit.) Remove the needle for these steps, re-inserting a new one at the end.

To oil the top stuff:
1. Open the door on the left.
2. Remove a couple of screws on the top. Remove the top. (Don't lose the screws.)
3. Use a brush (a mascara type brush like you can get at a drugstore or beauty supply works great, or get this brush) to get out all the dust and lint you can get to. Avoid blowing big chunks of dust deeper into the machine.
4. Put a bit of sewing machine grease (I use Tri-Flow) on any metal gears. If there's crusty white lithium grease anywhere, chip out and remove it, and replace with a bit of Tri-Flow. If there's no grease at all on a plastic gear, just leave it be. (Nylon is naturally low-friction especially against nylon.)
5. Put a drop of oil everywhere two pieces of metal move against each other. There will be 4-5 oil points along the main shaft that runs the length of the machine (every time it passes through metal or the housing, there's a bearing that needs oil). Sometimes they even cast little arrows into the housing to help you remember. Don't forget the eccentric thing that has a fork that rides against a big bearing surface. Put a drop there too.
5. Put a drop at each point the needle bar runs through part of the housing. Put a drop at every joint on the takeup lever.
6. Run the machine at low speed for 15-20 seconds, then moderate speed for another minute or so to help the oil penetrate.

To oil the bottom:
1. Get access to the bobbin area. Remove the bobbin case and retaining ring for the hook. Pull out the hook. Examine the hook for any burrs/nicks. (Emery paper or an emery board will remove those if found.)
2. Remove the needle plate. Use an emery board if it's nicked or will otherwise catch fabric.
3. Remove any lint, thread, dust you find around the feed dogs and around the bobbin/hook.
4. Remove any cover plate(s) on the bottom. Remember how everything goes. (Your cameraphone is an asset here.) Keep up with the screws.
5. DO NOT disconnect any gears under there. (You just blew the repair budget if you have to re-time the machine.)
6. Put a drop of oil on the bottom shaft similar to what was done at the main shaft.
7. Put a drop of oil on anything that rubs other metal at the feed dogs.
8. Put one drop of oil on the race where the hook rides. (ONE DROP).
9. Replace the hook and retaining ring (all cleaned up), and screw/clip it back in.
10. Again run the machine for 15-20 seconds on low speed, and another minute at moderate speed. You can leave the bobbin case out for now. KEEP YOUR FINGERS OUT OF THE WORKS.

To oil the motor:
1. Regardless of whether the motor is within the housing, or mounted on the back, put a drop (ONE DROP) of oil at each end where the shaft exits the machine. Many motors have one or two small oil holes, especially on the closed-end of the motor, where you drop oil. The zoom spout on the oiler is helpful here. Don't put too much or the motor will smoke and smell bad. You want it just on the little bearing that supports the shaft.

The machine should be noticeably quieter already. Now listen closely to each part of the machine and try to discern any other noisy connections. If you hear one, look for something to oil. Put a drop where you find it. In general, resist the temptation to over-disassemble.

Now check the bobbin tension. Put in a bobbin and thread the bobbin case. Holding the loose thread, the bobbin case should not slide down. If you can jerk your hand upward slightly, and the case falls a few inches, tension is correct. If it falls too easily, tighten the tension a bit (just crank the screw about 1/6 turn clockwise then re-test). If it doesn't fall at all, loosen slightly (again, 1/6 turn COUNTERclockwise then re-test). Repeat until tension is correct.

Replace the bottom covers. Replace the top cover. Put in a bobbin. Put in a new needle. Thread the machine. (Thread goes from the spool to some kind of thread guide, around the tension assembly, pulling up the little spring until the thread falls into the little hook on the tension assembly, then through the take up lever, through a thread guide (possibly) at the bottom of head, then down to the needle. All machines go spool, optional thread guide (usually present), tension assembly, take up lever, and needle. Don't thread through the small tension disc on top of the machine except when winding a bobbin.

Bring up the bottom thread (turn the handwheel overhand toward you), set tension to 3-4 (typically) and see how it goes.

If all is well, re-oil the machine about monthly, or more often if you use it daily.

Thank you, FraBasil.
I printed your instructions out and keep them with the manual now.
They are easy to understand and follow. Thanks for taking the time.

You're all welcome.

I did a search on YouTube. There are several videos out there that might make some of my steps clearer. I won't recommend any of these because I disagree with the ones I watched at some points. (e.g., why mess with an expensive can of compressed air when you can use a rag, cotton swab, and a your own lungs as necessary; the hook race DOES need oil so wiping it away is no good; I don't recommend Marvel oil as a substitute for sewing machine oil or Tri-flow).

I guess I should consider making a short video of my own.
