2. Safety Instructions
- Always operate the machine on a stable, flat surface.
- Ensure the machine is securely clamped to the table before use to prevent movement and ensure smooth operation.
- Keep fingers and loose clothing away from moving parts, especially the needles and crank handle, during operation.
- Do not force the crank handle if it becomes stiff; investigate the cause (e.g., tangled yarn, dropped stitch).
- Use appropriate yarn types and weights as recommended to avoid damage to the machine or poor knitting results.
- Keep the machine out of reach of small children when not in use. Adult supervision is recommended for younger users.
- Do not attempt to modify the machine or use non-original parts.

4. Setup
- Unpack the Machine: Carefully remove all components from the packaging.
- Choose a Stable Surface: Place the knitting machine on a sturdy, flat table or workbench.
- Secure the Machine:
- Using Table Clamps: Attach the two table clamps to the designated slots on the machine's base and tighten them securely to the edge of your table. This provides enhanced stability during operation.
- Using Suction Cups (Optional): If your table surface is smooth, you may use the provided suction cups by pressing them firmly onto the table beneath each leg of the machine.

5. Operating Instructions
5.1 Yarn Selection and Loading
- Choose yarn suitable for machine knitting. Medium-weight yarns (DK, worsted) are generally recommended. Avoid very thick or very thin yarns, which can cause issues.
- Feed the yarn through the yarn guide at the top of the machine.
- Adjust the yarn tension using the tension dial. The machine offers 4 yarn density settings to accommodate different yarn weights and desired fabric density. Experiment to find the optimal setting for your project.
5.2 Knitting Modes
The SENTRO knitting machine features two primary knitting modes, selected via the gear switch:
- T-Gear (Tubular Knit): This mode is used for circular knitting, producing seamless tubes. It is ideal for items like hats, socks, gloves, and doll bodies.
- P-Gear (Plain Knit): This mode is used for flat panel knitting, producing flat pieces of fabric. It is suitable for items such as scarves, blankets, bags, and sweater panels.

5.3 Starting a Project (Casting On)
- Ensure the gear switch is set to your desired mode (T or P).
- Feed the yarn through the yarn guide and into the first needle.
- Slowly turn the crank handle. The first few stitches will be picked up by alternating needles. Continue turning until all needles have picked up yarn.
- Once all needles are engaged, you can increase cranking speed.
5.4 Using the Row Counter
The built-in row counter automatically tracks your progress, displaying the number of rows knitted. This is particularly useful for projects requiring specific lengths or patterns. Ensure the counter is functioning correctly before starting a project. If the counter does not advance, check for obstructions or ensure it is properly engaged.
5.5 Finishing a Project (Casting Off)
Once your project reaches the desired length:
- Cut the yarn, leaving a tail long enough to secure the stitches (approximately 30-50 cm).
- Continue cranking slowly, guiding the yarn tail through each stitch as it comes off the needles. Use the crochet hook to help if needed.
- Once all stitches are off the machine, pull the yarn tail through the remaining loops to secure them.
6. Maintenance
- Cleaning: Regularly clean the machine to remove lint and yarn fibers that can accumulate around the needles and gears. Use a soft brush or compressed air.
- Oiling: Periodically apply a small amount of machine oil to the moving parts, especially the needles and the internal gear mechanism, to ensure smooth operation. Refer to the manufacturer's guidelines for specific oiling points.
- Storage: When not in use, store the machine in a clean, dry place, away from direct sunlight and extreme temperatures.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Stitches are dropping or uneven. | Incorrect yarn tension, yarn too thick/thin, machine not stable, cranking too fast. | Adjust yarn tension. Use recommended yarn weight. Ensure machine is securely clamped. Crank at a consistent, moderate speed. |
| Crank handle is stiff or jammed. | Yarn tangle, dropped stitch, lint buildup, machine needs oiling. | Stop immediately. Check for tangled yarn or dropped stitches and correct them. Clean lint from needles. Apply machine oil to moving parts. |
| Row counter not working. | Counter mechanism obstructed or disengaged. | Check if the counter is properly engaged and free from obstructions. Ensure the top is not being held down, which can prevent it from advancing. |
| Knitted fabric is too loose or too tight. | Incorrect yarn tension setting. | Adjust the yarn tension dial to a higher setting for tighter fabric or a lower setting for looser fabric. |
