If the thread gets caught in the hook, the safety device is automatically actuated, preventing possible hook damage. Pressing the reset button will immediately return the machine to the normal state.

With its unison feed mechanism that ensures a smooth and steady feed of materials, the machine provides consistent seam quality with no material slippage. Eleven different kinds of needle gauges are prepared for the LG-158. The most suitable gauge for the current machine use can easily be selected.

Since the machine incorporates a vertical-axis large hook, the frequency of bobbin thread replacement is reduced, further increasing efficiency.
