Frequently Asked Questions
I am breaking a lot of needles and the tension is getting too tight on its own while stitching and causing the thread to break. I am learning the machine for two weeks. Is it so sensitive too wools, cottons, and fleece that this would make such a major difference in the stitching - breaking needles, breaking thread?
(A) It may not be tension that is causing the problem with your portable blindstitch. If you have broken needles it has probably left some needle burrs in the thread and needle path that need polishing off with fine emory cloth (crocus) before sewing again.
Start with a new LWx6T needle without thread or fabric. Watch the needle as you turn the hand wheel. If there is needle deflection, reduce the penetration dial until there is no needle movement. If there is needle deflection caused by burrs, they must be polished off. Check the looper tip and two arms for any needle burrs and polish off. If there is needle deflection caused by the needle track lifting the needle, lower the track very slightly with the screws on the side of the black metal bracket above the needle.
Finally, Back off on the tension dial and retighten while you are sewing with a light strong thread and light to medium weight fabric, until you get the correct tension without loops. If tension is too tight it will push the thread up so it is not all the way down between the tension discs where it belongs.
(Q) I can't understand how to finish off at the end. It
always unravels. I have read the manual and it seems simple but I
apparently just "don't get it." Any help would be appreciated.
(A) At the end of the blindhem seam, position the needle all the way to the left, then use the knee lift to remove the fabric and jerk on the fabric at the same time. That will tie off the tread and break the thread at the
needle without bending the needle. You can weave the thread tail back into the stitches or cut it off. Before the above procedure, you could also turn the handwheel counterclockwise for a few stitches, then come back to the end of the seam and repeat the first procedure above.

No this machine does not use a bobbin. I just purchased one too and called the supplier to help me keep mine threaded. He said they do not take much tension at all. So check your tension and then when threading it, make sure your thread goes under the bar in the center of the tension disk, not on top of.
Good luck, once you get it going it does a beautiful job!!!! Love it, Love it!

Generally going to have to be addressing the drive motor, either substituting a lower speed clutch motor for the existing one, ie if you have 3000 rpm motor, then going to a 1725 rpm motor. Alternatively, selling the clutch motor and buying a servo motor instead, which should be available with a variable maximum speed control. The Sewquiet 4000 can select different speed ranges with the flick of a switch. If you already have a servo motor and it does not have a variable max speed, then switching the drive pulley on the servo motor to a smaller size should help
A more convoluted solution would be building a support under the table for a layshaft with different pulley sizes so that the motor could drive one pulley and then a smaller pulley on the shaft would drive the sewing machine. Not a bolt on solution but pretty cheap to do if you are good at fabricating.
