• Replace or correctly change the needle. Make sure that the needle is 

pushed up into the needle bar clamp until it can go no farther (visu-

ally check that it is up to the top of the stop/sight opening above the 

needle bar clamp screw). Failure to do so can cause damage in the 

bobbin area and throat plate.

• Correctly position the needle, throat plate or hopping foot.

• Balance the tension of the needle thread after ensuring the bobbin  

   tension is adjusted correctly (refer to page 20).

• Replace the needle with a size better suited for the fabric.

• Adjust the tension of the needle thread if it is not balanced with that of 

the bobbin thread. 

• Since thread slides over the surface of the bobbin case at a high 

speed, make sure the case is free of any material that could impede 

thread passage through the machine.

• Synchronize machine movement and needle speed to get roughly 

8-10 stitches per inch. Elongated stitches are an indication of moving 

the machine too fast for the current speed.

• Clean the track and the rubber wheel on each stitch regulator. Even 

a tiny speck on the wheel can cause problems with regulation. Check 

the spring tension on each stitch regulator assemblies. If the retaining 

nut is even slightly too tight it can prevent the wheel from properly 

pressing against the track.
