Product Overview
The Oiveinya Industrial Leather Sewing Machine Model 8700 is a robust straight stitch sewing machine head designed for heavy-duty applications. Its construction from high-quality iron with a high-temperature spray paint treatment ensures durability and wear resistance.
Key Components
- Thread Guide: This component allows for precise selection and routing of the thread according to specific sewing requirements.
- Adjusting Stitch Clamp: Used to regulate the tightness of the bottom thread. Turning the clamp clockwise increases tension (shorter stitch appearance), while turning it counter-clockwise loosens the tension (longer stitch appearance).
A hand adjusting the stitch length dial, which features numerical markings from 0 to 5 for precise control over stitch size. - Oil Quantity Monitoring Port: A transparent port designed for convenient visual inspection of the oil level, ensuring adequate lubrication during machine operation.
- Replaceable Presser Foot: The machine is equipped with a presser foot that can be interchanged with various functional presser feet (one included) to accommodate diverse sewing tasks and materials.

Installation
Due to the specialized nature of industrial sewing machines, it is highly recommended that personnel with professional knowledge and experience perform the installation of the machine head onto the motor and tabletop rack. Incorrect installation can lead to malfunction or injury.
Refer to the separate installation instructions provided with your motor and tabletop rack for detailed assembly steps.
Operating Instructions
Powering On
Once the machine is fully assembled and connected to a suitable power source via the motor, turn on the motor's power switch.
Threading the Machine
Follow the threading path indicated on the machine. Ensure the thread is correctly seated in all guides and tension discs.
Adjusting Stitch Length and Direction
The machine features clearly marked gauge chucks from 1-5 for stitch length adjustment.
- To adjust stitch length, rotate the gauge chuck to the desired setting (1-5).
- The reverse stitch switch allows you to change the sewing direction for back-tacking or reinforcing stitches.
Adjusting Thread Tension
The adjusting stitch clamp controls the tightness of the bottom thread.
- Turn the clamp clockwise to make the bottom thread tighter (shorter stitch appearance).
- Turn the clamp counter-clockwise to loosen the bottom thread (longer stitch appearance).
- Test on a scrap piece of fabric to achieve balanced tension.
Lifting the Presser Foot
Use the manual presser foot wrench to lift the presser foot. Turn it 90° to the right to raise the foot, allowing for fabric placement or removal.
Sewing
Place your fabric under the presser foot. Lower the presser foot. Begin sewing by gently pressing the foot pedal (if using a foot pedal motor) or engaging the motor. Guide the fabric smoothly.
Maintenance
Cleaning
The surface of the machine is smooth and flat, making it easy to clean.
- Regularly wipe the machine's exterior with a damp cloth.
- Remove lint and dust from the bobbin area and feed dogs using a small brush or vacuum cleaner.
- Ensure the machine is unplugged before cleaning any internal components.
Lubrication
Monitor the oil quantity through the Oil Quantity Monitoring Port. Refer to your motor's manual for specific lubrication requirements and recommended oil types. Proper lubrication is crucial for the machine's smooth operation and longevity.
Troubleshooting
This section provides general guidance for common issues. For complex problems, consult a qualified technician.
- Machine Not Starting: Check power connections, motor switch, and ensure the motor is functioning correctly.
- Skipped Stitches: Verify needle insertion, ensure the correct needle type for the fabric, and check thread tension.
- Thread Breakage: Inspect for incorrect threading, burrs on thread path, improper tension, or a damaged needle.
- Uneven Stitches: Adjust thread tension (both upper and lower), ensure consistent fabric feeding, and check for proper stitch length setting.
- Noise/Vibration: Ensure all components are securely fastened. Check for lubrication levels.
