Thread Break Troubleshooting
Common Causes of Thread Breaks
-
•
Improper Threading
Thread must pass smoothly through all thread guides. Missing a guide or incorrectly routing the thread can introduce excess tension and cause breaks. Ensure the thread is wrapped correctly around the thread break sensor wheel to prevent false thread break alerts. -
•
Thread Snagging
Inspect the thread path for areas where the thread may snag, including the thread base or guides. Any resistance in the thread path can result in breakage. -
•
Bobbin Threading and Rotation
The bobbin must rotate clockwise when viewed from the front and must be correctly threaded through the pigtail. Incorrect bobbin orientation or threading can cause frequent thread breaks. -
•
Bobbin Winding Quality
Inconsistent bobbin winding can cause breaks across multiple needles. Self-wound bobbins may vary in tension and consistency compared to pre-wound bobbins. Ensure bobbins are evenly wound and properly tensioned. -
•
Needle Condition and Installation
Dull needles or needles with burrs in the eye can shred thread. Replace needles regularly and verify proper installation:- ◦Eye facing forward
- ◦Scarf facing the rear of the machine
-
•
Thread Quality and Storage
Old or damaged thread can weaken and break. Store thread at room temperature, away from heat and direct sunlight. -
•
Tension Settings
Excessively tight tension increases thread stress and can cause breaks. Tension should be tested and adjusted according to fabric, thread, and design density. -
•
Burrs on Metal Components
Burrs can form on the needle plate or thread guides, often caused by needle breaks. Inspect and smooth or replace damaged components as needed. -
•
Picker Adjustment
Incorrect picker positioning can cause thread “pop-out.” Over-adjustment to eliminate long thread tails can result in cutting issues. Adjust cautiously to balance tail length and cutting performance.

Bobbin Identification and Insertion
Begin by identifying the components referenced in this procedure:
- •Size L bobbin
- •Bobbin case
- •Split bobbin case
- •Tension arm
- •Bobbin case pigtail
- •Bobbin case latch
- •Bobbin housing unit
- •Rotary hook
If this is the first time inserting a bobbin into a new machine, remove the protective foam located inside the rotary hook. Open the bobbin housing unit and discard the foam before continuing.
Threading the Bobbin Case
Hold the bobbin and pull the thread to confirm it rotates clockwise. This orientation is required for proper stitch formation.
With the thread running clockwise, insert the bobbin into the bobbin case. Guide the thread through the metal slit on the case. Continue routing the thread underneath the tension arm with the bobbin case pigtail facing upward.
Wrap the thread around the pigtail two full rotations in a clockwise direction. Rotate the bobbin case to confirm the printed lettering turns clockwise when pulling the thread. If the thread rotates counterclockwise, the machine will not pick up the bobbin thread.
Installing the Bobbin Case
Hold the bobbin case by the release arm with the pigtail facing up. Insert the case into the rotary hook located inside the bobbin housing unit. Press firmly until a click is felt, indicating the case is locked into position.
Close the bobbin housing unit to complete installation.
Removing the Bobbin Case
Open the bobbin housing unit. Grasp the bobbin case by the release arm and pull it straight out of the rotary hook.
Thread Rack Assembly
Assembling the Thread Rack
- •Loosen the hex screws at the bottom of each thread rack post using a 2.5 mm Allen wrench. Remove the thread rack and set it aside.
- •Remove the bottom nut from each post and place the nuts onto the two mounting pegs. Position the thread rack over the pegs.
- •Install the top thread rack section and secure the columns by rotating them clockwise.
- •Tighten the bottom hex screws to secure the assembly.
- •Loosen the adjustment knobs and raise the thread rack to its highest position. Retighten the knobs once the desired height is reached.
- •Insert pegs into the holes. Place foam pads on each peg, followed by white spacers. For mini spools, omit spacers so spools rest directly on the foam.
Changing Thread Spools
- •Untie existing threads from the top rack. Align each thread with its corresponding spool position.
- •Tie the end of the new thread to the existing thread using a secure knot. Pull thread through until old thread has passed through.
- •Trim excess thread and thread the needle front to back. Pull under the presser foot and rest it on the trim bar to cut excess length.
Threading the Bobbin (Alternate Procedure)
Hold the bobbin case with the pigtail facing upward. Hold the bobbin so the thread exits on the right-hand side. Insert the bobbin into the case.
Guide the thread into the slit on the right side of the case, then route it upward to the pigtail. Wrap the thread two full clockwise rotations around the pigtail.
Pull the thread to confirm clockwise rotation. Insert the bobbin case into the sewing arm with the pigtail facing up. Press until a click confirms it is locked.
Leave the thread tail extended and close the bobbin door.
Upper Threading Procedure
- •Place thread spool on the peg. Guide thread through the eyelet above the spool, then into the metal eyelet behind the tension knob.
- •Seat the thread between the tension plates and hook it behind the small tooth at the 3 o’clock position.
- •Unhook the thread tube. Attach thread to threading tool and feed through the tube. Reattach tube once threaded.
- •Route thread under the metal clip. At the lower tension assembly, place thread behind the small tooth at the 4 o’clock position.
- •Guide thread to the thread brake wheel: pass left of the metal knob, wrap one full rotation around the wheel, then continue left of the knob again.
- •Route thread under the silver plate, then right of the two metal bars, into the center of the black spring, and back up to the left of the two metal bars.
- •Pass thread through the take-up lever from right to left. Bring straight down into the yellow eyelet, behind the tension bar, then into the second eyelet.
- •Thread the needle front to back. Pull thread into the presser foot center and rest the end on the spring bar. Trim to approximately one inch.
Stabilizer Overview
Stabilizer, also called backing, supports fabric during embroidery and prevents movement, distortion, and puckering. Stabilizer is typically hooped with the garment and stitched along with the design.
Selection depends on fabric type, garment structure, and design density. In general, thick fabrics require lighter stabilizers, while lightweight or unstable fabrics require heavier stabilizers.
Common Stabilizer Weights
- •Lightweight: 1–2.5 oz
- •Medium weight: 2–2.75 oz
- •Heavyweight: 3–3.5 oz
Cutaway Stabilizer
Provides permanent support and is trimmed after embroidery. Recommended for stretch fabrics, frequently washed garments, and high-density designs or fine detail.
Tearaway Stabilizer
Provides temporary support and is removed by tearing after embroidery. Used on firm, non-stretch woven fabrics such as towels, robes, blankets, leather, caps, and bags. Multiple layers may be used.
Specialty Stabilizers
- •No-show cutaway (poly mesh): Lightweight cutaway for light garments with minimal show-through.
- •Topping (water-soluble film): Placed on top to prevent stitches from sinking into textured surfaces. Backing is still required underneath.
- •Fusible stabilizers: Bond to fabric using heat and are used for highly stretchable materials or to cover stitch backs.
- •Water-activated stabilizers: Adhere when moistened and provide a firm hold for precise placement.
