I have threaded the machine to the diagram that is on the machine , so when I have finished there are 4 threads that are pulled out the foot is up and the material is placed in position . I begin to sew and the cotton has not overlocked with each other .
The machine may need to be taken in to be checked to see if it's
out of time

You need to adjust the tension for your threads. Use scraps to test sew as you adjust the individual threads to bring them into proper balance. Your manual will tell you how to do this.
Good evening madam
It sounds like there is something wrong with the electrical system in your sewing machine. You can check the power and connections.
good luck

Open up the front cover. There should be a diagram right there, and you want to thread your serger step-by-step per the color-coded diagram so that the needle is in time with the movement of the loopers. If you randomly go about threading it instead of in sequence, the threads will collide and you will create a jam. The usual threading order: Upper Looper, Lower Looper, Left Needle, then Right Needle. Do you have long serger tweezers? Do you have a Looper Threader? If not, these are great tools to assist you as the Lower Looper is threaded right to left- an eye all the way to the far left, so it helps to have the tweezers and Looper Threader to maneuver in this very tight area. Many new serger users don't realize that other eye is "hiding" and miss threading it! Hopefully, you have a manual with additional pictures to help guide you. If you need a manual, try allsewingparts.com and perhaps they have one specific to your serger. Note: When you insert your needles (make sure they are #11 and #14 specific for your particular machine), the left needle will be the same size as right needle, but will APPEAR higher once both are pushed up into each of their respective needle shafts. Note: Hold onto needles or put a piece of fabric under the area when changing them/replacing them because they can easily fall out causing damage to your machine. Hope this helps. Jimmy
The hobbylocks all thread in much the same fashion. There is a diagram for a four thread hobbylock on this website. It would be better if you found a Pfaff dealer to show you as it is quite complicated.

Once you have it threaded, always cut the old threads at the spool and knot new ones on and pull through. You will have to thread the needles as the knots will not pass through but it does save an awful lot of frustration when needing new colours on the spools.
