Causes: |
Improper Thread Try re-threading the machine; make sure the thread goes through all guides. |
Burrs There may be burrs in the needle's eye, on the thread guides, needle plate or the hook. Replace the needle and try buffing the thread guides and needle plate. Buffing may alter the timing, so it's a good idea to replace a damaged hook. |
Dry Hook Because it dries out faster, the hook needs frequent lubrication. The hook assembly should be lubricated every 4-8 hours of machine running time. |
Needle to small You may have to change to a larger needle |
Too much Adhesive spray You should be using only Embroidery designed adhesive sprays, never over use them. Too much adhesive build up on the needle can cause them to drag and break threads. If this is happening you should examine the way you use your adhesive spray |
Improper timing If your machine isn't timed properly, it can cause many probems in addition to thread breaks. Such as broken needles, poor stitching or sometimes no stitching. |
Old Thread Thread can become brittle with age and long exposure to light, air and heat. You should store your thread in a cool, dark place to lengthen shelf life. |
Bruised cone A bruised cone of thread can occur if the thread falls on the floor, causing the lower winding of thread to loosen and catch as the thread spools off. You can take off the affected part of the thread or replace the cone. |
Machine speed Some of the designs increase the stress on thread. You should lower the machine speed as needed |
Lint build up A lint build up on the tension discs, needle plate or bobbin cases can cause breakage. These areas should be cleaned frequently with air or a brush. |
Bent needle This can happen after the needle hits a very hard object such as a Hoop, needle plate or the hook. If this happens you have to replace the needle and check for burrs and the timing. |
Improper tensions If the tension is too tight, it can cause pulling, puckering and thread stress. If the thread is too loose it can cause the thread to pile up and loop. You have to adjust the tensions to achieve a flat smooth look. |
Using Tape for loose ends Using tape can leave a residue and this can cause friction and thread breakage. |
Holding the thread If you hold the loose end of the thread when you start up the machine and you are pulling the thread too tight, it can cause the needle to bend or break and can also cause the thread to break. |
Stitches form wrong or not at all |
Causes: |
Empty Bobbin replace |
Retaining finger in wrong position loop can not form |
Improper Timing the bobbin hook won't catch the loop |
Needle position is incorrect can cause the timing to be off |
Damaged hook replace |
Missed stitches |
Causes: |
Wrong Needle Size in relation to the thread and this can make it difficult for loops to form |
Thread is to tight or to loose causes irregular loops to form |
Timing is incorrect can cause the bobbin hook to not catch the loop |
Needle breaks |
Causes: |
Bent needle replace |
Dull needle will bend and eventually break, replace |
Timing wrong damage to needle and hook and poor stitch quality |
Holding thread during startup can bend the needle and break the thread |
Needle is inserted wrong insert all the way up the needle bar shaft and needle screw is tight |
Needle cuts holes in garment |
Causes: |
Dull needle difficult to pierce garment causing tearing |
Needle point is wrong type wrong point can damage some fabrics, try a ballpoint |
Needle to large can stretch fabrics |
Fabrics are to delicate may have to use a topping |
The design is out of register |
Causes: |
Garment is hooped to loosley re-hoop but do not stretch fabric |
The fabric is unstable you may have to use a heavier backing |
Garment is puckering |
Causes: |
Tensions to tight for a particular thread or garment
|
Improper hooping
|
Unstable fabric
|
Dull needles
|
Too many stitches in an area
|
These are some of the normal problems you may experience during the Embroidery Process.
