Q & A

What is the first step before operating the single-needle industrial sewing machine?

The first step is to ensure the machine and thread pole are properly installed and then turn off the machine using the switch button before starting any setup.

How should the lubricating oil be filled in the machine?

Lift the machine body to open the lubricating oil filling port, pour sewing machine lubricant until it reaches the indicator limit, and remove any excess oil using a valve with a screwdriver.

What are the steps for winding a bobbin using the right-side bobbin winder?

Insert the thread into the hole, wrap it around the tension plates ensuring proper clamping, make several turns around the bobbin to lock the thread, place the bobbin on the winder pole, step on the pedal to wind until full, then release and remove the bobbin.

How does the top-mounted bobbin winder differ from the side-mounted one?

The top-mounted bobbin winder has two tension holes on the tension plate; the thread is passed through both holes before winding, while the side-mounted winder uses a single tension plate.

What is the correct way to insert the filled bobbin into the bobbin case?

Insert the bobbin counterclockwise into the bobbin case, pull the thread through the gap until it clicks, and leave a small length of thread in place before threading the upper thread.

How should thin threads like silk be installed to prevent tangling?

Thin threads should be guided through all holes and guides along the threading path to prevent tangling due to their delicate nature, while standard cotton thread does not require all guides.

When should the upper thread pressure be adjusted?

Adjust the upper thread pressure only if the resulting stitches are loose or if the fabric becomes wrinkled; factory settings are generally sufficient for standard cotton thread.

How can the stitch length be adjusted on this machine?

Use the stitch length selector to adjust stitch length up to 5 mm, and use the reverse stitch lever to lock stitches or to sew in reverse when needed.

What is the recommended procedure for changing the presser foot?

Use a mini screwdriver to remove the shoe bolt, optionally use the shoe clamp bolt for faster changes, and press the release button to remove the foot before installing a new one.

What maintenance steps are important to ensure the longevity of the sewing machine?

Turn off the machine, check the oil pan regularly, replace oil if it is cloudy or discolored, and clean out dust and fibers to maintain smooth operation.

How should the needle and thread be removed safely?

Ensure the machine is turned off and the needle is at the top position, then use a screwdriver to loosen the thread screw and a thread and needle feeder tool to safely remove the needle and thread.
