Proper timing on a Husqvarna sewing machine results when all moving parts work in harmony with thread to produce a well-stitched garment. If just one part is out of sync, it can lead to skipped or irregular stitches, broken needles and puckered fabric. No matter the model Husqvarna sewing machine you own, setting the timing does not have to be time-consuming or laborious and can generally be done at home with tools from the sewing machine accessory box.
Review your Husqvarna sewing machine model's operating manual. Since most timing problems occur from lack of proper maintenance, read these sections several times and take the recommended actions for cleaning and troubleshooting.
Remove the needle from the needle bar by unscrewing the needle clamp. Using a magnifier, check to see if it is bent or damaged at the tip. Place a new needle in the bar and turn the hand-wheel until it reaches its lowest position inside the needle plate. When your Husqvarna sewing machine is properly timed, the needle should easily clear the needle plate without touching.
Inspect the hook for lint, bits of thread and sticky residue from fabric sizing, and brush clean. Check that the bobbin is wound correctly and properly fitted inside the bobbin case and that the case is rightly positioned inside the race area. Turn the hand-wheel again to see that the bobbin thread is synchronised with the needle thread to sew regular stitches.
Test the motion of the feed dogs, the teeth under the needle plate that move the fabric through the sewing machine. Place a piece of fabric in the machine and start sewing. If the feed dogs are not moving in a full range of motion, the fabric will pucker. For accurate timing, the up, down and around motion of the feed dogs should be in sync with the rise and fall of the needle and the circular motion of the bobbin.
Check thread tension dials and remove any lint or thread that may have become lodged behind them. Proper tension is absolutely critical for both the top and bobbin threads and for accurate timing.
On most Husqvarna sewing machines, adjustments can be made easily. Some electronic and computerised sewing machines have built-in thread tension controls and unique pressure systems, making it difficult to adjust at home. In cases like these, take the sewing machine to a licensed Husqvarna dealer who is trained to make fine-tuned timing adjustments and related repairs.
