Brother 2340CV operation manual Presser foot pressure, 10mm 3/8 inch

•An example where adjustment is required

When stretch material is sewn without using the differen- tial feed, the material will be wavy.

To make the material more smooth, adjust the feed ratio from 1.0 toward 2.0.

(The feed ratio required depends on the elasticity of the material.)

The more elastic the material, the further toward 2.0 the differential feed ratio should be set. Test sew with a scrap of the fabric to find the correct adjustment.

CAUTION

When sewing thick non-stretchable material such as denim, do not use the differential feed as it may damage the fabric.

•The pressure of the presser foot can be adjusted by turning the pressure adjustment screw at the top left of this machine. Since this machine has already been adjusted to a pressure suitable for light to medium fabrics, no further adjustment is necessary except

when sewing on very heavy or very light materials.

4Usually, when sewing on very light materials, the presser foot pressure should be loosened. When

sewing very heavy materials, the presser foot pres- sure should be tightened.
