Before you choose
Questions about this machine.
How is the stitch system changed?
The catalogue describes changing the relevant conversion parts and selecting the matching program. It is a setup operation, not an automatic change between stitches during sewing.
What hemming dimensions can I request?
The catalogue gives a 9–42 mm hem width and a minimum tubular diameter of 50 mm. Send a sample of the smallest trouser leg and the thickest cross seam for review.
What matters when choosing a sewing machine for denim trouser hems?
Send the finished leg opening, hem width, fabric weight and thickest seam crossing. Confirm whether the garment needs lockstitch or chainstitch and check the puller and handling setup against the sample.
