3. Setup Instructions
Before connecting, ensure your sewing machine is unplugged from the power outlet.
- Identify Connections: Locate the motor and light input ports on your sewing machine. These are typically distinct ports designed for these specific connections.
- Connect Motor and Light: Plug the motor and light cords from the FC-143 pedal's block into the corresponding ports on your sewing machine. The block is clearly labeled "MOTOR" and "LIGHT" for correct identification.
- Connect to Power: Plug the main power cord of the FC-143 pedal into a standard 110/120V electrical outlet.
- Position Pedal: Place the foot pedal on the floor in a comfortable position for operation, ensuring the cords are not tangled or obstructing movement.

4. Operating Instructions
The YICBOR FC-143 foot control pedal is designed for single-speed operation.
- Power On: Ensure the sewing machine is switched on (if it has a separate power switch).
- Initiate Operation: Gently press down on the foot pedal to activate the sewing machine motor.
- Speed Control: This pedal provides a single, consistent speed when pressed. It is not designed for variable speed control. The motor will run at its designated speed as long as the pedal is depressed.
- Stop Operation: Release pressure from the foot pedal to stop the sewing machine motor.
5. Maintenance
Regular maintenance ensures optimal performance and longevity of your foot control pedal.
- Cleaning: Wipe the pedal's exterior with a dry or slightly damp cloth. Avoid using harsh chemicals or abrasive cleaners. Ensure no moisture enters the internal components.
- Cord Inspection: Periodically inspect the power cord and connection wires for any signs of wear, fraying, or damage. If damage is observed, discontinue use and replace the unit.
- Storage: Store the pedal in a dry, clean environment away from extreme temperatures and direct sunlight when not in use. Avoid coiling the cord too tightly to prevent damage.
6. Troubleshooting
If you encounter issues with your YICBOR FC-143 foot control pedal, refer to the following common solutions:
- Pedal Not Responding:
- Ensure all connections are secure: the motor and light plugs into the sewing machine, and the main power cord into the wall outlet.
- Verify the wall outlet is functional by plugging in another device.
- Check if the sewing machine's power switch (if applicable) is in the 'ON' position.
- Motor Runs Constantly or Sticks:
- Immediately unplug the unit from the wall outlet.
- Inspect the pedal mechanism for any obstructions or debris that might be preventing it from returning to the 'off' position.
- If the issue persists after clearing obstructions, the internal mechanism may be faulty, and the unit may require replacement.
- No Variable Speed:
- This pedal is designed for single-speed operation. It does not offer variable speed control. The motor will run at a consistent speed when the pedal is pressed. This is a design characteristic, not a malfunction.
