4. Setup
4.1 Unpacking
Carefully remove the machine and all accessories from the packaging. Inspect for any signs of damage during transit. Retain packaging for future storage or transport.
4.2 Power Connection
Connect the provided power cord to the machine's power input and then to a standard 110V electrical outlet. Ensure the connection is secure.
4.3 Thread Installation
Follow the threading path indicated on the machine. Ensure the thread is correctly routed through all guides and tension discs before passing it through the needle eye. Use the needle threader for assistance.
4.4 Initial Oiling
Before first use, and periodically thereafter, apply a few drops of sewing machine oil into the designated oil holes on the machine body. This ensures smooth operation and extends the machine's lifespan.

5. Operation
5.1 General Use
Hold the machine firmly by its ergonomic handle. Position the bag opening under the presser foot. Press the power switch to begin sewing. The machine operates at a fixed speed of 2600 stitches per minute, capable of closing a bag in approximately 2 seconds.

5.2 Adjusting Stitch Length and Tension
- Needle Bar Controller: Rotate this controller to adjust the height of the needle bar, accommodating different material thicknesses.
- Adjustable Thread Tension: Use the thread crimper to fine-tune the thread tension, which affects the appearance and strength of your stitch.
- Adjustable Pressing Force: Rotate the screw clockwise to increase pressing force of the presser foot, or counter-clockwise to decrease it.
The stitch length is adjustable between 7-10mm, allowing for fine stitches that create a firm seal, preventing contents from falling out.

6. Maintenance
6.1 Regular Oiling
Consistent lubrication is crucial for the machine's longevity and smooth operation. Apply sewing machine oil to all designated oiling points before and after each use, or as frequently as needed based on usage intensity.
6.2 Cleaning
Regularly clean lint, dust, and thread fragments from the needle area, presser foot, and feed dogs. Use a soft brush or compressed air. Ensure the machine is unplugged before cleaning.
6.3 Needle Replacement
Replace needles regularly, especially if they become bent, dull, or broken. Using a damaged needle can affect stitch quality and potentially harm the machine. Refer to the 'Wrench for needle' included in the package for assistance.
7. Troubleshooting
- Excessive Noise: Due to the high-speed motor (11000 rpm), some operational noise is unavoidable. However, if noise levels increase significantly or unusual sounds occur, check for proper oiling and ensure no parts are loose or obstructed.
- Skipped Stitches or Poor Stitch Quality: Verify that the needle is correctly installed and not bent or dull. Check thread tension and ensure the thread is properly routed through all guides. Adjust the needle bar height according to material thickness.
- Thread Breakage: Inspect the thread path for any snags or sharp edges. Ensure the thread tension is not too high. Use appropriate thread for the material being sewn.
- Machine Not Powering On: Confirm the power cord is securely connected to both the machine and the electrical outlet. Check the outlet for power.
