Maintenance
To maintain your Caydo Electric Yarn Winder, simply wipe the unit with a clean, dry cloth after each use. Ensure no yarn fibers or dust accumulate in the moving parts or around the tension springs. Do not use harsh chemicals or abrasive cleaners.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Machine stops or yarn snags | Yarn tangle, knot, or excessive tension. | Turn off the machine. Clear any tangles or knots. Ensure yarn is fed smoothly. Restart the machine by turning the knob off and then on again. |
| Yarn cakes are loose or uneven | Insufficient tension, incorrect threading, or winding speed too high. | Ensure yarn is threaded through all tension guides. Check that the tension spring coil is correctly positioned. Reduce winding speed. |
| Machine struggles to pull yarn from a swift | Resistance from the swift or yarn type. | The winder is not recommended for use with a swift. If used, manually assist the swift to reduce resistance, especially at the beginning of winding. |
| Machine makes unusual noises or vibrates excessively | Unstable setup, yarn type incompatibility, or internal issue. | Ensure the winder is securely clamped to a stable surface. Avoid winding super bulky, very thin, smooth, or highly elastic yarns (e.g., acrylic, polyester) as they may not be suitable. |
| Yarn fibers are stripping | Repeated winding/unwinding or abrasive guides. | Minimize re-winding. Ensure yarn is not catching on any rough edges. |
