Before you choose

Questions about this machine.

How does D4 differ from D3?

The catalogue identifies automatic presser-foot lifting as an additional D4 function. Confirm the required control functions when ordering.

Can it sew my fabric?

Share the fabric type, layer count and seam photo. These details determine the needle, thread and suitable working speed.

What should I compare on a direct-drive industrial sewing machine?

Compare the complete model suffix, thread-handling functions, foot lifting and seam requirements. Direct drive describes the motor arrangement; it does not mean that every machine includes the same automatic functions.
