Question about Toyota STF17 Sewing Machine

Open Question

Why do I have to operate my machine without the end cover.

The upper thread on my machine continually unhooks inside the cover causing the thread to be dragged into the bobbin housing then breaking and jamming. It appears that when the needle goes down, the thread billows inside the cover causing it to come unhooked. The only way to stop this from happening is to operate the machine without the end cover (over the light). I have had my machine for 3 or 4 years and it has always done this.

Hi,

For some reason the bobbin thread must be too hard to pull for the needle to pick it up.Take the bobbin out of the bobbin case and clean the bobbin case thoroughly. Thread and lint may be built up keeping the bobbin holder from turning.
Old the bobbin holder in one hand and pull some thread off the bobbin. You should feel a slight resistance but the thread should pull out fairly easily. If you feel too much tension, remove the bobbin and clean the bobbin holder thoroughly

If this does not resolve your problem, there may be some other mechanical failure.
the you will need to have it serviced.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

This usually indicates that there is an issue in the bobbin house. Either there is dust or the bobbin case is not working properly. Different bobbin sizes, such as prefilled plastic bobbins can also cause a hassle. try oiling the bobbin house and air blowing it clean. If you have any further questions please message me back. Please also remember to rank this opinion as to how helpful it was towards your appliance situation.
Thanks again,

SOURCE: My top thread keeps breaking. I have adjusted the

sometimes the needle plate gets a burr on it which will break the thread when sewing. Usually 2 screws hold the needle plate on and remove those and pull the needle plate off. Take a close look at the hole that the needle travels into and see if its a little rough on both side. If so you can use a file on it to smooth it back down.

I have a 9020 singer sewing machine I bought without a manual. I can't seem to sew without looping the thread under it. Almost in knots.


Are you saying the upper thread is knotting under the fabric as it stitches? This is bird nesting or thread nesting and is generally caused by mis-threading, the thread not being seated in the tension disk, or the upper tension too loose.

When threading the upper thread, ALWAYS RAISE the presser foot. Verify that the machine is threaded correctly. If one guide is missed, the stitching will go haywire. Start out with the upper tension set around the midway point and then tweak it through test stitching.

Thread bunches up into a knotted mess on bottom. Bobbin doesn't sit flat inside the bobbin case but spins with a tilt, lower on the left and higher on the right. Bobbin touches plastic cover plate.


Usually, thread bunching under the fabric is an upper tension issue. Be sure to ALWAYS RAISE the presser foot when threading the upper thread.

With the bobbin case operating at a tilt, there is something mechanically wrong with the machine. It may be best to take it for service.

My thread is caught in the upper tension and won't pull out up or down. How do I remove it?


What I am getting from your question is that you have thread caught in the upper tension assembly? If this is the case I would remove the top plastic lid on the machine. It's easy to remove as it is only held on by 2 torx head screws. Also remove the plastic end cap on the machine. Just one torx head screw holds on the end cap cover. Now with these two covers removed you can see the entire upper thread path and pull out or remove the thread from where it is caught. On a 180 it usually gets cought at the end of the take up arm where the thread passes through. Use some good tweezers to remove any cought thread. Also turn the hand wheel and inspect the moving parts for any thread that has broken off and gotten wrapped up in the moving parts.

Why does the check upper thread notice continue to come on when the thread is not broken?


I suspect fluff or lint is interfering with the sensor. Might be time for servicing.

The motor locked up because the thread is tangled. Remove the tangled thread before continuing the operation.Clean the bobbin case to remove the tangled thread. After cleaning the bobbin case, insert the bobbin case properly. If the needle is bent or broken, replace the needle.Then, thread the upper thread properly, and continue the operation.

While embroidering my machine continually stops and shows error message "Check upper thread" but, thread if fine. Why is this happening?


It's possible that the upper thread sensor has become disconnected from the check spring in the takeup mechanism. This also results in poor or inconsistent thread formation and sometimes a bit of a ticking noise on the upward stroke of the takeup arm. It's also possible that the optical sensor that is attached to the back of the front panel, just above the reversing button, has become obstructed by fluff. In either case it's best to have it checked-out by a Bernina service agent although it is just-about possible to re-position the sensor flag on the check spring without removing the front panel, if this is the problem. If you remove the head cover (T20 screw) and look at the bottom of the metal curved takeup arm cover, you should see what appears to be a large flat-bladed screw with a coil spring around it - this is the check spring. If you follow the end of the spring, you'll see it emerges into the bottom of the takeup arm cover and forms a small loop. If you thread-up the machine as far as the takeup arm and gently pull upwards on both ends of the thread, you'll see that this pulls the spring upwards too. Whilst looking at this, look carefully at the section of the spring between the main coil and the thread loop - it should run through a groove in a small black plastic part - if not, the check spring has come off the sensor flag. This often happens if you pull the upper thread 'backwards' through the machine after finishing sewing, or when changing the upper thread. You should always cut the thread where it comes off the spool and pull the waste through the machine in the normal direction. If you can see the end of the sensor flag, it may be possible to reposition the check spring through the groove, but its not easy and really needs to be done with the front panel off, which is a technicians job and not for the amateur. Dont forget that you can disable the upper thread sensor through the set-up menu, but this wont necessarily overcome problems with stitch formation.

Artista 180 - I keep getting error message to check upper thread - happens almost every stich - changed thread, changed fabric, changed needle - error keeps happening...any ideas?


There are a number of possible reasons for this, but, assuming the thread hasn't actually broken (!), it may well be that the upper thread sensor flag has come off the check spring - this is something I see fairly regularly and is frequently the result of people pulling the upper thread 'backwards' out of the machine a bit too quickly, rather than cutting it off at the spool and drawing it through the machine in the correct direction. It's a bit fiddly and very difficult to explain how to check this, without taking all the covers off. However .... if you take the head cover off (single screw) and look carefully at the bottom of the metal takeup lever cover you will see a large slotted screw with a spring wound around it - this is the check spring. The end of the check spring pokes-out behind the takeup lever cover and the thread goes through a loop in its end when you thread the machine up. Thread the machine up as far as the takeup lever, take hold of both ends of the thread and gently raise it - you should see the check spring move upwards. Now, look very carefully at the part of the spring between the big coil around the screw and the loop where the thread passes-through ... there should be a black plastic part attached from the other side of the takeup mechanism (you cant get at this without taking the front cover off !). If it's not attached, you can very very carefully wiggle the spring and sensor flag back so that the spring sits in the slotted part of the sensor flag (either that or take it to your Bernina service agent !). If the sensor appears to be attached, it could also be the optical sensor which is attached to the front cover just above the reverse switch - sometimes this gets full of fluff or I have seen a couple with manufacturing faults where the sensor flag gets caught in the optical sensor circuit board ... whatever the case, this is really a job for the service agent.
Good Luck

I have a hard time threading this machine and a hard time getting the bobbin thread to come up.


Hello

Place spool of thread on the spool pin, found inside the carrying handle on the top right side of the machine facing the back.


Lead thread through the upper thread guide, located just beyond the machine's handle.


Lead thread through the second upper thread guide, found a few spaces to the left of the first upper thread guide mentioned in Step 2.


Bring thread around the second upper thread guide down into the thread guide.


Lead thread toward you down through the tension discs.


Continue to pull thread down through the ****. Forming a "U" shape, bring thread back up the left side of the guide, catching the check spring as the thread moves back up through the guide on the left side.


Bring thread up to the take-up lever and insert thread through the eye of the lever in a right-to-left motion.


Lead thread downwards, slipping it down through the horizontal thread guide.


Guide thread through the wire thread guide that is attached to the needle clamp.


Insert thread through needle from front to back, pulling thread four to six inches to create a thread extension. The machine is now threaded.

Check upper thread


These machines typically have threading issues. In the thread path, there is a sensor that reads the thread. It quite often gets lint and pieces of thread. Where the thread goes through the thread path on the upper read is usually the culprit. Take off the plastic cover where the thread goes from rear towards front...look for the metal plates and carefully clean between them. You also need to make sure that thread goes all the way to the inside of these discs. I try to always pull the thread from spool and thread end to make sure it gets properly seated.
