Before you choose
Questions about SF-V99-D4
What is the difference between SF-V99-D3 and SF-V99-D4?
The catalogue describes automatic backtacking for both. D4 adds automatic presser-foot lifting, which is relevant when the operator frequently repositions the work.
Can this machine replace a heavy-duty upholstery machine?
Choose according to the actual assembly and feed requirements. Bulky upholstery or difficult layered leather may need a dedicated compound-feed or long-arm machine instead.
Which details are needed for a quotation?
Send the fabric, layer count, seam type, thread, order quantity and destination. Include any required electrical supply and control functions so the configuration can be confirmed.
