4. Setup
Follow these steps to assemble your knitting machine:
- Attach the Legs: Insert the four bracket legs into the corresponding slots on the underside of the main machine body.
- Apply Anti-Slip Pads: Secure the four anti-slip pads to the bottom of each leg.
- Secure Legs: Use the provided screws and screwdriver to firmly attach the legs to the machine body.
- Attach Crank Handle: Connect the crank handle to its designated slot on the side of the machine.
- Attach Yarn Guide/Tensioner: Install the yarn tensioner into its slot.
- Choose Placement Mode:
- Clamped to a Workbench: If using the machine on the edge of a table, attach the two steel brackets to the machine's legs and secure them to the table edge (supports 0.1-7.5cm thickness).
- Flat Surface: Alternatively, place the machine directly on a stable, horizontal surface.



5. Operating Modes
The SENTRO knitting machine features two primary knitting modes, easily switchable via the P/T gear conversion key:
- P Gear (Plain Weave): This mode is used for flat knitting, suitable for items like scarves, bags, sweaters, pillows, and clothes. It allows for needle reduction.
- T Gear (Ring Weave): This mode is for circular knitting, ideal for creating items such as hats, gloves, and rag dolls. It maintains a fixed stitch number.

6. Knitting Process
Follow these general steps to begin knitting:
- Select Mode: Choose either P-gear (plain weave) or T-gear (ring weave) using the conversion key.
- Thread Yarn: Guide your chosen yarn (1.5mm-5mm thickness) through the yarn guide and tensioner.
- Start First Stitch: Turn the crank to the "Up-down mode" position. Carefully hook the first needlework with the yarn.
- Continuous Knitting: Continue turning the crank. The machine will knit one stitch at a time. After completing one full turn, ensure each hook is properly engaged with the yarn, then continue turning the crank directly.
- Monitor Progress: The built-in row counter will help you track your progress.

Yarn Tension
Proper yarn tension is crucial for consistent knitting. Experiment with the tensioner settings to achieve the desired tightness for your project. The machine supports various tension levels:
- Loose
- Moderate
- Tight
- Tightest

7. Maintenance
To ensure the longevity and optimal performance of your knitting machine:
- Cleaning: Regularly clean any lint or yarn fibers from the needles and moving parts using a soft brush or cloth.
- Lubrication: Periodically apply a small amount of machine oil to the moving components as recommended by the manufacturer (if applicable, consult the original manual for specific points).
- Storage: Store the machine in a clean, dry place away from direct sunlight and extreme temperatures. Keep it covered to prevent dust accumulation.
8. Troubleshooting
If you encounter issues during knitting, consider the following common problems and solutions:
- Skipped Stitches or Dropped Stitches:
- Check yarn tension: Ensure the yarn is not too tight or too loose. Adjust the tensioner.
- Verify yarn thickness: Use yarn within the recommended range of 1.5mm-5mm.
- Inspect needles: Make sure no needles are bent or damaged.
- Ensure proper threading: Re-thread the machine, making sure the yarn is correctly placed in all guides and hooks.
- Machine Jams:
- Check for tangled yarn: Remove any tangles or knots in the yarn supply.
- Reduce yarn tension: If the yarn is too tight, it can cause jamming.
- Clear debris: Remove any accumulated lint or yarn bits from the machine's mechanism.
- Uneven Knitting:
- Maintain consistent cranking speed.
- Adjust yarn tension for uniformity.
Common Misconceptions to Avoid

9. User Tips
- Practice with Scraps: Before starting a large project, practice with scrap yarn to get a feel for the machine and tension settings.
- Yarn Choice: While the machine is versatile, some users find that certain yarn types (e.g., very fluffy or very thin) may require more careful handling or tension adjustments.
- Project Size: For larger items like adult jumpers, consider knitting panels and then seaming them together, as the circular capacity might be limited for very wide items.
- Watch Tutorials: The provided video tutorial and other online resources can be very helpful for visual learners.
