- Page 25 2) Upper Thread Tension Adjustment [CAUTION] Thread tension adjustment is critical for producing high quality of the embroidery. A balance of 2/3 upper thread and 1/3 lower thread generally indicates good tension. If the tension is too loose, the upper thread will loop, causing thread tangles or breaks.
- Page 26 3) Take-Up Spring Correct Wrong The take-up spring stopper does not touch the spring The take-up spring (when the spring tension is weak or when the stopper is stopper touches the spring mis-located) Take-up spring stopper Take-up spring [Fig.4-7] ① Take-up Spring Functions Difference in the length of the upper thread pulled by the take-up lever and pulled by the hook creates tension or looping.

Page 29: Floppy Disks And Precautions
[CAUTION 1] Winding the bobbin off-center or uneven as shown below can cause thread breaks, skipped stitches, or thread tangles. [Fig.4-14] [Fig.4-15] [CAUTION 2] Too tight tension of the bobbin thread may block smooth pulling of the thread and cause thread breaks or short tails. -
Page 30: Needle-Hook Timing Control
4-7) NEEDLE-HOOK TIMING CONTROL 1) Needle ① It is very important to select the right needle for the type of thread and fabric used. ② Inappropriate needle may cause bad embroidery, thread breaks, skipped stitches, etc. ③ For normal embroidery, use a DB×K5 needle. [CAUTION] DB K5 needle has an eye twice larger than that of DB1 (used for normal sewing). - Page 31 ② When inserting the needle, make sure that the Needle insert hole groove of the needle is facing front. Shaft of the needle should be inserted completely into the needle bar. Front groove of the needle groove [Fig.4-18] [CAUTION 1] For special threads such as artificial silk, turn the needle slightly to the right to prevent thread breaks (see [Fig.4-19]).

- Page 33 [CAUTION] Functions by Needle Shape ① Size of the hole and groove differs by needle. ·Front groove: protects the thread from the heat of the Front groove sewing friction (which may cause thread breaks). ·Back groove: helps regulate the hook timing and prevents looping.
- Page 34 5) Relationship between the Take-up Lever and the Hook Hook point timing is directly related to thread tension and thread breaks. The following pictures show the location of hook when the take-up lever starts to move up from the lower dead stop (main shaft rotation angle: 292°).
