Place the sewing machine on a stable, level surface. Ensure adequate lighting for your work area. If your machine is treadle-operated, ensure the treadle mechanism is free from obstructions.
Menggulung Bobbin
To wind the bobbin, first release the balance wheel (D, Fig. 3) to disengage the sewing mechanism. This allows the bobbin winder to operate independently. Follow the specific threading path for bobbin winding as indicated in your machine's design. Once the bobbin is full, re-engage the balance wheel.

Mula Menjahit
To begin sewing, raise the presser foot (B, Fig. 3) using the presser bar lifter. Place your fabric under the presser foot, aligning the edge with the desired seam allowance. Lower the presser foot onto the fabric. Begin operating the machine by turning the balance wheel towards you or by engaging the treadle/motor. Guide the fabric gently as the machine stitches.
Adjusting Stitch Length and Tension
Refer to your machine's specific controls for adjusting stitch length and thread tension. Proper tension is essential for a balanced stitch, where the upper and lower threads interlock evenly within the fabric layers.
Penyelenggaraan
Pembersihan
Regular cleaning is vital for smooth operation. Use a small brush to remove lint and dust from the bobbin case, feed dogs, and other accessible areas. Avoid using harsh chemicals.
meminyaki
Apply a small amount of good quality sewing machine oil to all moving parts as indicated in your machine's specific oiling points. Over-oiling can attract more lint, so use sparingly. Consult a detailed diagram for precise oiling locations.
Penggantian Jarum
Replace the needle regularly, especially if it becomes bent, dull, or if you experience skipped stitches. Always use the correct type and size of needle for your fabric and thread.
