Apply 2–3 drops of high-grade industrial sewing machine oil directly into the hook race.

Clean out all packed lint, shredded thread fragments, and broken needle pieces lodged in the hook race.

error, many users find success by raising the machine head and manually rotating the wheel to clear thread jams in the shuttle or bobbin section. Cleanliness

To avoid triggering the ERR list, maintain the machine according to 2021 industrial guidelines:

Try rotating the handwheel manually to check for smoothness.

Most error codes arise from preventable mechanical or electrical issues. Implement these maintenance practices to minimize disruptions:

Install a dedicated voltage stabilizer if your facility experiences frequent power fluctuations. E02 / Err-02: Undervoltage Protection

The input voltage supply to the control box exceeds the maximum safe threshold, or there is a surge in the power line. Action Steps: Power off the machine immediately.

Turn off the power before threading, replacing needles, or cleaning the machine.

The machine doesn't know where the needle is. Check the synchronizer (the sensor on the handwheel) to see if it has slipped or become unplugged.

| Error Code | Common Meaning | Recommended Action | | :--- | :--- | :--- | | | Motor running error | Check motor and encoder; restart machine. | | E-006 | Pause key pressed at standby | Press RESET key to clear. | | E-007 | Pause key pressed while sewing | Press RESET key to clear; restart if needed. | | 10 | Emergency stop switch pressed | Press RESET key to clear error. | | 11 | Pause switch pressed | Press RESET key; move presser foot, continue sewing. | | 100 | "GREASEUP" reminder ignored | Add grease, then perform clearing operation. | | 111 | Incorrect stop position | Check trimming device or sewing motor for abnormalities. | | 121 | Trimming cannot complete | Check fixed knife and movable knife blades for scratches or damage. | | 130 | Main motor failure | Main shaft motor or motor controller failure. | | 131 | Synchronizer poor contact | Check motor motherboard plug P11 connection. | | 150 | Main motor abnormal heating | Overheating from short-cycle sewing; check motor cooling. |

This error triggers when the direct-drive servo motor encounters resistance and cannot rotate the main shaft.

The table below provides a complete list of error codes, their descriptions, and recommended actions based on this official source.

Inspect the mechanical linkages connected to the trimming knife under the needle plate. Ensure they move freely.

The rating reflects the machine's reliability and performance while also considering the learning curve and support needed for troubleshooting errors. With better support and resources, the Siruba L818FM1 could offer an even more satisfying experience for its users.

The is a popular direct-drive, high-speed, 1-needle lockstitch sewing machine frequently used in industrial settings. While robust, the machine features an electronic control box that displays error codes (e.g., E1, ERR3) to indicate issues with the motor, position, or power supply.

Check the emergency stop button on the machine panel and ensure it is released. ERR10 - Counter Set to 0 Description: The thread counter has reached zero. Troubleshooting: Reset the counter to continue operation. 2. General Troubleshooting for Siruba L818FM1

Turn the machine off, wait 30 seconds, and turn it back on. If the error continues, you may need to reset the control box parameters, which should only be done by a trained technician. 2021 Maintenance Tips for Siruba L818F

Proactively managing these core systems will keep your industrial production lines running efficiently while preventing costly component replacements.
