1. Open the front cover by sliding it to the right and guiding the top toward you.

   

    

2. Pull the thread off the spool and directly up through thread holder (1) and thread holder (2) on the thread tree, from back to front.

   

    

3. Pass the looper thread (3) as shown in the illustration.

   

   • Make sure that the thread is passed under the pretension plate on the thread guide. (A)

     

      

   • When using thick thread, such as decorative thread, as the looper thread, run the thread as shown in the illustration.

     

     Do not run the thread through (A) when using thick thread.

    

4. Pass the thread through the tension disc (4) in the channel next to the tension dial marked with a blue .

   

    

5. Guide the thread down the channel and through threading points (5) - (9), following the numerical order in the illustration.

   

   • Make sure that the thread is passed under the thread guide (5) in the looper thread take-up.
   • Make sure that the thread is passed over the looper thread spring (6).
   • Make sure that the thread is passed through the loop of the thread guide (7).

   

    

6. After running the thread to (9), push the looper release lever (10) to move the looper to the right (11), and then run the thread through (12) - (13).

    

    

7. Pull about 10 cm (4 inch) of thread through the eye of the looper.

    

8. While pushing the looper (14), return the looper to its original position.

   

    

9. Close the front cover.

5. Pass the thread through the eye of the needle, front to back. (9)

   

 

2. Threading the center needle

 

Run the thread in the sequence illustrated, following the green numbers and (green) marks next to the threading points.

 

1. Pull the thread off the spool and directly up through thread holder (1) and thread holder (2) on the thread tree, from back to front.

   

    

2. Pass each thread through (3), shown in the illustration.

   

   Make sure that the thread is passed under the pretension plate on the thread guide. (A)

   

    

3. Pass the thread through the tension disc (4) in the channel next to the tension dial.

   

    

4. Guide the thread down the channel and across through threading points (5) - (8) next to the color marks, following the numerical order in the illustration.

   

   (A) Left needle thread
   (B) Pass the center needle thread through the right side of the branching plate.
   (C) Right needle thread
   (D) Branching plate

   • Make sure that the thread is passed under the tension plate on the needle bar.

     

      

   • Make sure that the thread is passed behind the thread guide on the needle bar.

     

    

5. Pass the thread through the eye of the needle, front to back. (9)

   

 

3. Threading the right needle

 

Run the thread in the sequence illustrated, following the pink numbers and (pink) marks next to the threading points.

 

1. Pull the thread off the spool and directly up through thread holder (1) and thread holder (2) on the thread tree, from back to front.

   

    

2. Pass each thread through (3), shown in the illustration.

   

   Make sure that the thread is passed under the pretension plate on the thread guide. (A)

   

    

3. Pass the thread through the tension disc (4) in the channel next to the tension dial.

Attaching the top cover spreader and top cover thread guide and threading the top cover spreader

When sewing a cover stitch on both back and top side, attach the top cover spreader and top cover thread guide to the machine, and then thread the top cover spreader.

 

Attaching the top cover spreader and top cover thread guide

 

1. Turn the handwheel so that the line on the handwheel (A) is aligned with the line (B) on the machine.

   

    

2. Squeeze the grip of the top cover spreader to spread the tips, and then, from the right side, clamp the mount of the top cover spreader onto the top cover drive shaft.

   

   (1) Grip of top cover spreader
   (2) Mount of top cover spreader
   (3) Top cover drive shaft

   Make sure that the top cover spreader is inserted till the end.

    

3. Insert the top cover thread guide into the slot in the top cover thread guide mount.

   

   (4) Top cover thread guide
   (5) Slot

   Make sure that the top cover thread guide is inserted till the end.

 

Threading the top cover spreader

 

Run the thread in the sequence illustrated, following the purple color and the numbers next to each threading point.

 

1. Pull the thread off the spool and directly up through thread holder (1) and thread holder (2) on the thread tree, from back to front.

   

    

2. Pass each thread through (3), shown in the illustration.

   

   • Make sure that the thread is passed under the pretension plate on the thread guide. (A)

     

      

   • When using thick thread, such as decorative thread, as the top cover thread, run the thread as shown in the illustration.

     

     Do not run the thread through (A) when using thick thread.

    

3. Pass the thread through the tension disc (4) in the channel next to the tension dial marked with a purple .

   

    

4. Guide the thread down the channel and across through threading points (5) - (9) next to the color marks, following the numerical order in the illustration.

   

    

5. Turn the handwheel counterclockwise to move the point of the top cover spreader completely to the left.

    

6. Thread the point of the top cover spreader as shown in the illustration (10).

   

    

7. Pass the top cover thread under the presser foot, from left to right, as shown in the illustration (11), and then lower the presser foot.

   

    

8. Turn the handwheel counterclockwise 2 to 3 times to check that the top cover thread forms stitches.
