Operating Instructions
The SENTRO knitting machine offers two primary knitting modes:

Switch between flat (P) and circular (T) knitting modes.
Getting Started (First Round of Yarn)
- Thread the yarn through the tensioner.
- Turn the crank slowly. As the first needle comes up, place the yarn behind it.
- For the second needle, place the yarn in front of it. Continue alternating placing the yarn behind and in front of each needle as you turn the crank for the first full round.
- After the first round, ensure the yarn is consistently fed through the tensioner and all needles are catching the yarn correctly.
Circular Knitting Mode (T-Gear)
This mode is ideal for creating tubular items such as hats, scarves, and socks.
- Set the conversion key to the 'T' position.
- Follow the 'Getting Started' instructions for the first round.
- Once the first round is complete, continue turning the crank clockwise at a steady pace. The machine will automatically knit the stitches.
- Monitor the yarn tension and ensure no stitches are dropped.
- To finish, cut the yarn, leaving a long tail. Turn the crank slowly and use a crochet hook or needle to carefully remove each stitch from the needles.
Plain Knitting Mode (P-Gear)
This mode is suitable for flat panels, such as blankets, scarves, or pieces that will be sewn together.
- Set the conversion key to the 'P' position.
- Follow the 'Getting Started' instructions for the first round.
- Turn the crank clockwise until the machine reaches the end of the row and reverses direction automatically.
- Continue turning the crank, allowing the machine to knit back and forth.
- To finish, cut the yarn, leaving a long tail. Turn the crank slowly and use a crochet hook or needle to carefully remove each stitch from the needles.

The SENTRO knitting machine is user-friendly for all ages.
Maintenance
- Cleaning: Regularly remove any lint or yarn fibers that accumulate around the needles and gears using a soft brush or cloth.
- Storage: Store the machine in a clean, dry place away from direct sunlight and extreme temperatures.
- Lubrication: If the crank becomes stiff, apply a small amount of silicone-based lubricant to the moving parts, avoiding contact with the yarn path.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Dropped stitches | Yarn not properly tensioned, yarn too thick/thin, crank turned too fast, or needles stuck. | Adjust yarn tension, use appropriate yarn, turn crank slowly and steadily, check for obstructions. |
