There are a number of reasons you would want to have a Baby Lock products registered:
The cover stitch creates a double or triple row of stitching and it can be done in narrow or wide widths with the triple cover stitch. It can also be used 'upside down' for a braid-like look. It can be used for functional or decorative purposes, such as:
Decorative edges are a great place to start. They can be created with an array of threads from fine to heavy weight. Here is your general serger set-up:
The serger should be cleaned after each project is completed. If you are working on a large project that creates a lot of lint build up, you may need to clean the machine a couple of times while working on the item. You can clean the serger yourself by using an air compressor, your vacuum cleaner, or your hair dryer set on cool. Problems that can occur if a machine is not cleaned on a regular basis are: inconsistent stitching, a noisy machine, and improper feeding. Avoid these problems by making sure to clean all thread guides and brush the lint off the knives and feed dog frequently using the brush that included in the accessory pack.
You can check the following things. Was the needle inserted properly? Is the needle bent or worn? Are the right and left needles threaded with the correct threads?, Was the fabric pushed or pulled through machine? Is good quality thread being used? If the problem persists take the machine to an authorized Baby Lock Dealer for service.
Outside Corners: Stitch to the end of the corner edge, but not beyond. Stop with the needles up and raise the presser foot. With tweezers pull approximately 1/4" of slack thread above the needles. The slack will allow the fabric to be pulled slightly to the back, clearing stitches from the stitch fingers. Turn the fabric, aligning the new edge with the edge of the needle plate. Remove any slack from the needle threads. Lower the foot and continue sewing.
Inside Corners: Cut an inside corner in a piece of fabric. Line up the edge of the fabric with the edge of the needle plate. Begin sewing. Stitch until the needles are about one inch away from the corner. Lower needles to secure the fabric and raise the presser foot. Manipulate the fabric until the cut edge pulls straight and a pleat forms to the left of the presser foot. Continue sewing until the inside corner is complete.
Check to see if your differential feed is on. If it is not supposed to be on set the differential at N.
Make sure the cutting blade is at the correct width setting.
Check upper and lower looper tension settings.
Make sure the machine is threaded properly and the threads are in the tension disks.
The only place to oil the serger is the upper looper arm where it is connected to the machine. Turn the handwheel by hand to notice where the looper moves back and forth.
Place a drop of oil at this point. Anything else the machine needs to be taken to your Baby Lock dealer for periodic maintenance.
You can use regular sewing machine thread. However, make sure you have enough thread to finish the project. Sergers use more thread than a sewing machine. You may also need to adjust the tension settings (if there are tensions) because sewing thread is heavier than serger cone thread. Also be sure to use spool caps when using a regular spool of thread.
