Machine Out Of Timing

It is rare for the machine to go out of timing, but the most frequent cause is spiking the hoop. Spiking means that the needle strikes or is embedded in the hoop while sewing. When this happens, the machine is stopped abruptly, jarring the mechanical parts.

Even if the machine does not go out of timing, spiking the hoop will likely break, or at least dull the needle. It is a good idea to change the needle, whether or not it is broken.

If the presser foot and the hoop collide, the presser foot may be bent enough that it rubs the needle and causes thread breaks.

However, even if spiking the hoop occurs, it does not automatically mean the head is out of timing. When you have a sewing quality problem, check the following before adjusting the sewing head timing:

	Tension settings (upper and lower)
	Needle condition, size, and type of point
	Lubrication of hook assembly and head
	Nicks in the presser foot or needle plate
	Presser foot height
	Stitch density
	Proper sewing technique for the material, backing and thread
	Material properly hooped
	Needle Bar depth too low or too high
