PRELIMINARY INFORMATION

Do not run your machine threaded before placing your material. The thread will clog and break.

Remember that you cannot pull the material faster than the machine feeds. Guide the material, but do not pull it or you may bend or break the needle.

REGULATING THE TENSIONS

Fig. (27) If the tensions of your machine are adjusted correctly, the stitches will lock in the center.

On a lock stitch sewing machine, if the tensions are properly regulated, the thread links in the exact center of the fabric. The stitch on the right and wrong side of the goods will look identical. See Fig. 27.

Fig. (28) If the needle tension is tight, the thread lies flat on the upper surfaces.
