Thread paths differ between models. Treat the precise needle and guide routing diagram in your manufacturer’s manual as authoritative, especially for machines that switch between cut and loop. This overview covers the general checking procedure, not a substitute for that diagram.
Step 1: Disconnect power

Unplug the machine before placing hands near the needle, guides, scissors or moving mechanism.
Step 2: Prepare a free-running yarn supply

Place the cone or ball so yarn can unwind without snagging against corners, furniture or nearby equipment.
Step 3: Follow the model-specific yarn path

Pass yarn through the machine’s designated guides and needle using the exact diagram provided for your model.
Step 4: Check the yarn and needle relationship

Confirm that the yarn sits in the prescribed position and that no slack hangs into moving parts.
Step 5: Test on scrap cloth

Reconnect power only after clearing the needle area. Make slow, short passes and observe whether loops or cut tufts hold consistently.
Step 6: Correct jams with power off

Stop and unplug before clearing a tangle; never pull fibers toward a moving blade or needle.
If yarn still skips, visit the skipped stitches guide before changing internal timing.
