4.2 Needle Installation

Use needle type 135 x 17. To install a new needle:

1. Turn the handwheel to raise the needle bar to its highest position.
2. Loosen the needle clamp screw.
3. Insert the new needle with the long groove facing left and the scarf facing right. Push it up as far as it will go.
4. Tighten the needle clamp screw securely.

4.3 Bobbin Winding and Insertion

Refer to the machine's threading diagram for specific bobbin winding and insertion instructions. Ensure the bobbin is wound evenly and inserted correctly into the large horizontal axis hook.

4.4 Threading the Machine

Follow the numbered threading path on the machine, guiding the upper thread through all tension discs, thread guides, and the needle eye. Ensure the thread is seated correctly in the tension assembly.

5. Operating Instructions

Familiarize yourself with the machine's controls before beginning to sew.

5.1 Power On/Off

Use the main power switch, typically located on the table stand, to turn the machine on or off. The servo motor provides precise speed control.

5.2 Adjusting Stitch Length

The stitch length is adjusted using the locking stitch regulator dial located on the machine head. Rotate the dial to select the desired stitch length. The maximum stitch length is 3.6 stitches per inch (7 mm).

5.3 Reverse Stitching

To engage reverse stitching, press and hold the reverse lever. Release the lever to resume forward stitching. This function is used for securing seams at the beginning and end of a stitch line.

5.4 Presser Foot Lift

The presser foot can be lifted by hand (up to 5/16" or 8 mm) or by using the knee lifter (up to 5/8" or 16 mm). The knee lifter allows for hands-free lifting of the presser foot, which is beneficial when handling large or heavy materials.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your sewing machine.

6.1 Lubrication

Periodically check the oil level in the oil pan and replenish as needed. Ensure the adjustable oil flow is set correctly for continuous lubrication during operation. Refer to the oil gauge for proper levels.

6.2 Cleaning

Regularly clean lint and thread debris from the bobbin area, feed dogs, and tension discs. Use a soft brush or compressed air. Disconnect power before cleaning.

6.3 Needle Replacement

Replace needles frequently, especially when sewing dense or heavy materials, or if the needle shows signs of bending or dullness. A dull or bent needle can cause skipped stitches, thread breakage, or damage to fabric.

7. Troubleshooting

This section addresses common issues that may arise during machine operation.

• Skipped Stitches: Check if the needle is inserted correctly and is not bent or dull. Ensure the correct needle type (135 x 17) is being used. Verify proper threading of the upper thread and bobbin.
• Thread Breakage: Inspect the thread path for any snags or sharp edges. Check upper thread tension; it may be too tight. Ensure the needle is not bent or dull.
• Uneven Stitching: Adjust upper and lower thread tension. Ensure the presser foot pressure is appropriate for the material being sewn. Verify that the material is feeding smoothly.
• Machine Not Starting: Check if the power cord is securely plugged in and the main power switch is on. Ensure the motor is functioning correctly.
• Noise or Vibration: Ensure all screws and bolts are tightened. Check for any loose parts or obstructions. Verify that the machine is properly lubricated.
