Before you choose
Questions about SF-0356-D4/AT
Is this a compound-feed machine?
The model title specifies top-and-bottom feed. Do not assume that every long-arm machine uses the same needle-feed or compound-feed mechanism. Compare the required layer control before ordering.
What is the difference from SF-0385-D4/AT?
Both belong to the long-arm range, but their working-space arrangements and packing dimensions differ. SF-0356-D4/AT lists 1020 × 340 × 630 mm packing. Send your workpiece size to compare the required arm clearance.
Can it sew leather and upholstery?
These are relevant applications for the range, but the material thickness, finish, thread and seam must be reviewed together. Send a sample or clear photographs before choosing the final configuration.
