In order for the sewing machine to produce the correct stitches, the timing needs to be correct. The timing refers to having all the parts working in harmony. If the machine starts to jam after one or two stitches, then the timing is off. It is quite rare for the timing to go off but when it does, the machine will not work properly. Many timing issues are due to improperly installed needles. However, if cleaning the machine and changing the needle does not help, then you should reset the timing. Brother embroidery machines use a vertical needle and hook system.
Check that the needle is properly installed. Most timing problems occur because the needle is installed backwards or the wrong needle is used.
Clean the machine and bobbin area of any dirt, lint or debris with a vacuum and brush. Pull out the bobbin and needle plate, and lubricate the moving parts with sewing machine oil. Use a clean rag for large moving parts and cotton swab for the smaller moving parts.
Rest the timing of the needle and hook. Adjust the height of the needle bar so it is at the lowest point of the stitch cycle. Loosen the set screw with a small screwdriver. The set screw holds the needle bar in place but do not completely remove the screw.
Align the marker line for the needle you are using to the lowest point of the needle bar lower brushing. Once this marker is aligned, tighten the set screw with a screwdriver. Check the machine manual for the correct marker to use. Starting from the bottom marker on the needle bar, the desired marker will be the second or third form the bottom. DA needles will use the second marker from the bottom and DB needles use the third marker from the bottom.
Loosen the set screws that hold the hook in place. Move the needle bar so the bottom needle bar marker line lines up with the lowest part of the needle bar lower brushing.
Move the hook blade point so it aligns with the centre of the needle. Allow for a clearance of 0.1 millimetres between the hook and needle. Tighten the three hook setscrews with a screwdriver.
