SM Balance Wheel

Description

The balance wheel (also known as the handwheel) on a sewing machine is a crucial component that helps control the movement of the needle and fabric. It is typically located on the right side of the machine and can be turned by hand to manually control the machine’s needle motion.

Here’s how the balance wheel functions:

1. Manual Control: The balance wheel is often used to move the needle up and down manually, especially when you want to adjust the needle position or thread the machine. It can be turned clockwise or counterclockwise depending on the specific machine model.
2. Connecting the Mechanisms: The wheel is connected to the drive system inside the sewing machine. When the machine is running, the balance wheel rotates, which in turn drives the needle and the feed dogs to move the fabric under the needle.
3. Adjusting Tension: On some machines, you can use the balance wheel to adjust the needle’s position relative to the fabric, particularly when the needle is in its highest or lowest point.
4. Regulating Speed: In many cases, the balance wheel allows you to control the speed of the machine’s operation when you’re sewing manually or need to go slowly to navigate curves or delicate stitching.

Using the Balance Wheel

• To hand-crank the machine: Rotate the balance wheel gently by hand to control the movement of the needle. This is especially useful if the machine is turned off, or if you want precise control over the stitching.
• To troubleshoot issues: If the machine is jammed or has issues, you can use the balance wheel to gently turn the needle and check for obstructions or to remove threads from the machine.

The balance wheel is essential for operating the sewing machine manually and ensuring that the machine’s internal mechanisms function smoothly. If it becomes loose or damaged, it can affect the machine’s ability to function properly.
