ELNA Zig Zag Cl. 21 - Understanding and Adjusting Tension; Universal Tension Settings; Troubleshooting Tension Issues

Universal Tension
With universal tension, most of the usual sewing
jobs can be done without changing the tension,
i.e.:
Fig.39
Upper tension: red number "5", facing the guide
mark.
Fig.40
Lower tension: red number "1", facing the tip of
the tension lever.
For certain jobs (nylon threads, hemstitching,
special seams, etc.), an adjustment can be made
by
turning the tension regulator knob.
If the lower tension has to be altered (nylon work),
turn the graduated screw with the screwdriver.
The graduation marks allow you to come back
easily to the universal tension.
