Questions and answers
how to set the walking dog with the timimg
To set the timing on the Typical GC20606-D2 walking dog, follow these steps:
1. Turn the balance wheel to lower the needle bar to its lowest position.
2. Adjust the trimming cam:
- Press down the trimming driven crank so the trimming roller enters the trimming cam groove.
- Turn the balance wheel until the white mark on the balance wheel aligns with the position mark on the arm.
- Loosen the two set screws on the trimming cam and rotate it to align the marks, then tighten the screws.
3. Adjust the upper feed if needed:
- Loosen the special bolt on the horizontal feed crank.
- Move the bolt upward to reduce upper feed or downward to increase it.
- Position it on the reference line for correct timing.
These adjustments ensure the feed mechanism (walking dog) moves in sync with the needle and other parts.

My machine keeps going out of timing and I cant get the proper stitching
To fix timing issues and improve stitching on a Typical GC20606-D2 machine, follow these steps:
1. Check the Timing Wheel: Ensure the timing wheel (part 1WF2-027 or 1WF2-043) is properly aligned and securely fastened.
2. Inspect the Needle Bar: Verify the needle bar and lower feed parts are properly installed and moving smoothly.
3. Adjust the Hook Timing: The machine uses vertical hooks for thread looping. Adjust the hook so it meets the needle at the correct moment when the needle is at its lowest position.
4. Verify the Feed Mechanism: Ensure the compound feed system is synchronized and the feed dogs are moving correctly to avoid uneven stitches.
5. Lubricate Moving Parts: Use the plunge oil pump lubrication system to keep the upper and lower shafts running smoothly.
6. Check Belt Tension: The synchronic belt should be properly tensioned to ensure smooth operation.
7. Tighten Screws and Bushings: Ensure all screws, bushings, and rotating shafts are secure to prevent misalignment.
If issues persist, seek professional service, as non-professionals should not attempt advanced repairs.
