Pfaff 238-0 User Manual

The downward stroke of the thread check spring is limited by a stop on the tension
barrel and can be adjusted by rotating this barrel, as may be required.
To do this, insert a screwdriver into opening E (Fig. 27), loosen the tension barrel set
screw and, inserting the screwdriver into the slot of tension stud M, turn the latter until
the tension barrel is in the correct position.
To adjust the thread check spring tension, turn tension stud M in the tension barrel.
If it should be impossible to turn the tension stud in the tension barrel with the aid of a
screwdriver, loosen the tension barrel set screw in opening E (Fig 27), take the tension
barrel out of the machine and slightly loosen the set screw at its rear end. After the
tension barrel has been replaced in the machine, the stroke of the thread check spring
must be readjusted.
