Pfaff 238 User Manual

In Fig. 17 either the upper tension is too tignt, or the lower tension too weak.
In Fig. 18
either the upper tension is too weak, or the lower tension too tight.
You will
have to decide in every individual case, if either the upper or the lower tension
needs to be adjusted, particulary when the thread forms small knots or kinks on top or
bottom of the fabric.
Always lower the presser bar before you adjust the upper tension. When the presser bar
is raised, it will automatically release the tension.
11. Regulating the Stitch Length
The stitch length is regulated by turning thumb nut S on the feed regulator lever (Fig.
19).
This applies to both straight and zigzag sewing.
Turn this thumb nut right for shorter stitches, or left, for longer stitches.
The numerals on the left of the slot indicate the stitch length in millimeters.
The feed regulator lever is permanently held down in forward feeding position by spring
action.
When you push the feed regulator lever up beyond the zero mark, the machine will feed
in reverse. The lever will return to its forward feeding position automatically, when re
leased (Fig. 19). This feature is particularly useful for backtacking.
