Before you choose
Questions about this machine.
Why choose a long-arm machine?
The longer working space helps accommodate large or bulky pieces to the right of the needle. Share the workpiece dimensions to check that 850 mm clearance is suitable.
Is the listed speed suitable for every seam?
The 2,000 rpm figure is the catalogue maximum. Working speed depends on the material, thread, needle and seam construction.
Is long-arm clearance the same as sewable material thickness?
No. The long arm gives room to handle the workpiece beside the needle. Material thickness and seam suitability depend on the feeding system, needle, thread, settings and component construction, which must be reviewed separately.
