Question about Sewing Machines

1 Answer

The knuckle attached to needle mast, giving up and down movent, is overheating?

I have cleaned and lubricated with sewing oil and Lanox etc and cannot stop the knuckle from overheating. Although it is much better now it is not right! It's just too tight! How do I free this up more or do I just need a new part altogether?

It would be a good idea to have the serger checked to see if it
needs to be adjusted and have the timing checked.

    Thankyou for your response. It's very annoying only overlocking for 2mins and having to stop due to the friction generated in that knuckle. Like I said it is much better now but it is still not right. Maybe there is a specific lubricant that is used here?

Oily cotton when stitching


Oily Cotton:
1. Remove the bobbin case.
2. Wipe out the oil.
3. Bobbin case rides unto an area that looks like a race track. (Called Race). Wipe out oil.
4. After cleaning oil out take a drop and place unto race.
5. Replace bobbin. (Wipe oil if there is any.)
6. Remove oil from the needle arm. (Goes up and down holding unto the needle.)
7. Replace a small amount of oil on the needle arm.
The sewing the machine should sew very well. It may have some resistance when you turn the hand wheel by hand. Likely, this is due to the machine being new and not being broke in. Otherwise, it would need to be lubricated throughout the machine. Give it while!

Hand wheel tight


If the hand wheel isn't turning freely here are possible problems.
1. Clean bobbin area and ensure bobbin case is inserted properly.
Also, put one drop of oil on race (bobbin case sets on it).
2. Check/remove material from feed dog.
3. Remove the thread and rethread with the pressure foot up while giving small tugs as you go to check for snags.
4. Afterwards put the pressure foot down and give a small tug to check for excessive resistance. It is a good idea to start at four. Now place thread in needle.
5. Put oil on needle arm and pressure foot arm.
6. When done it should work.
7. If this is still a problem the interior of the machine may need cleaned and lubricated.

Remove sewing maqchine case


Plate on bottom: Remove screws. Keep screws in safe place and oil moving parts with good quality sewing machine oil. Zoom with spout for sewing machines & servers is what I use purchased online...lubricate gears with Singer lubricant (in tube). Tip machine back onto a towel to remove screws. Just one drop oil on moving parts & dot of lube gear only if not showing signs of grease already. Please remove bobbin and presser foot before cleaning/oiling. One drop oil then generously SMEAR oil on oscillating hook, open right front door & one drop top of needle bar. Clean out race shuttle for lint, fuzz balls, broken threads with soft sewing machine brush & clean your feed dogs gently with bristles too. Hope this helps. Do not clean machine near children or curious pets! I run my machine with pedal on table top so I don't accidentally step on it. Control with right hand to see moving parts. At your own risk, of course. Safe and effective but only if you are extremely careful. Replace all screws securely. Put in new needle all the way UP into needle bar groove, presser foot UP turning handwheel towards you, flat end of needle to back, Thread Front to Back of needle.. Keeping presser foot raised @ highest position ensures thread locates the tension slots properly. Jimmy

It squeaks when u sew. i need to know where to oil it at


Squeaking or popping sounds could be a blunt needle so make sure you change it regularly, 4-6 hours sewing time is rule of thumb.

To find where to oil this machine download the manual from http://www.singerco.com/accessories/manuals.html, just type in your model number into the search field and click 'Search', most of the manuals are there as a downloadable pdf file.

The manual will show oiling points for your machine. Use sewing machine (clear) oil only, a little drop only but oil and clean regularly to get the best performance. Brush out any lint and dust first (don't use compressed air to blow a machine out, much better to brush out carefully with a little brush and remove the lint from the machine).

You can also put a drop of oil onto a piece of waste fabric then rub this up and down the needle bar (the metal part that goes up and down holding the needle) to keep this clean and lubricated.

My brothers pe 150 embroidery machine has never been serviced; can i get advice on cleaning, oiling, etc.


The manual has instructions for cleaning, which is basically removing the needle plate and bobbin case and cleaning the area with a soft brush or cotton swab. Some use canned air.

There is no oiling of computorized sewing machines.

Lubrication has to be done by an authorized tech.

If you oil and get it in the wrong place, it could interfere with the computer's sensors and create more problems.

Janome SD-2014 sewing machine dogs fails to operate in reverse


The grease has hardened and that is what makes it not work. You need to remove the spring and clean all the old grease off it. You can put new grease on if you want but it isn't necessary. The machine should be lubricated with a good quality sewing machine oil(not 3 in 1). You need to oil any place that moves and rubs, This includes the ends of each shaft, the needle bar and the cinnecting links that drive the needle bar. Nothing is permanently lubricated.. you'll find this machine will run much smoother and quieter with fresh lubrication.As a matter of fact, if you use the machine a lot, it should be lubricated once a year and never less thanonce every 5 years.
One more thing. If it is on the main shaft that it has hardened you can spray it with a mixture of fantastic, water and some ammonia. Free it up and give it a light shot of oil.

How do i oil my bernina 801?


Please do not oil anything with WD40, it is an alcohol based cleaner hense why it's flammable. No where on the container will it say anything about lubricating, it will merely dry out your machine. We use it, but only to clean metal parts... we then clean it off and let it evaporate for a day before applying oil.

There are two key points I suggest customers can do themselves to help lengthen the life of their machine. One is your hook and the other is the needle bar...
Hook - Open your bobbin door, removee the bobbin case/bobbin. On the upper left corner there is a small latch, push in the latch and your shuttle race ring will fall down forward. You can now remove your stainless steel hook. You need to keep this hook clean and the lip it fits back into clean and void of lint and debris. On the back of this hook or the "lip" that the hook fits back into apply a small amount of hook/sewing machine oil.
Needle Bar - Open up your head cover, the needle and needle bar clamp is attached to a long stainless steel rod that travels vertically inside your head. All sewing machines have a needle bar that looks like this. This bar travels thru two brackets attached to the frame of the machine. Rotate your handwheel and clean the needle bar well of debris. Rotate the handwheel so that the needlebar is in it's highest point and apply a small amount of oil to the upper and lower bracket of the frame, rotate the handwheel so the needlebar slides back down and therefore lubricating it and the inside of the brackets.
Hook oil or sewing machine oil is relatively inexpensive from all quilt, sewing machine, repair shops. Be sure to take your machine in a minimum of every three years for proper cleaning and lubricating of all the other parts (This is of course for average home sewing machine use 8hours a week)
