Questions about SF-591
Is SF-591 single needle or twin needle?
SF-591 is the single-needle version. The catalogue pairs SF-591 with SF-1591 in the one-needle table row; SF-592 / 1592 is the two-needle row.
Does SF-591 require compressed air?
The SF-591 / 592 series description says the machine is electronically controlled and does not require compressed air. Confirm any separately requested accessory requirements.
Can I specify needle spacing on the single-needle version?
The catalogue presents gauge options for the combined series. Needle-to-needle spacing applies to a twin-needle configuration; it is not a twin-needle feature of SF-591. State the exact seam and model in your enquiry.
