Universal Thread Tensions - ELNA TX Instruction Manual

Universal Thread Tensions
P
The universal settings make it possible for most
sewing jobs to be done without changing the tension,
i.e.:
Lower tension: red number '1", facing the lever.
Upper tension: number 5, framed zone, facing the
guide mark.
If the tension has to be changed (for certain Nylon or
metallic threads, special seams, etc.), it is usually the
upper tension that is modified by turning the knob, as
follows:
A good tension
The threads are locked properly between the two
layers of material.
Upper tension too strong
The lower thread is visible on top. Decrease the
tension, turn to the thinner lines, between 5 and 1.
Upper tension too weak
The upper thread is visible underneath the material.
Increase the tension, turn to the thicker lines,
between 5 and 9.
If the tensions are tried out for a particular sewing
job, do so on a double layer of a scrap of the material
(and not single), as will be the case when the final
sewing is done,
If the lower tension should have to be modified
nlflfl
(certain Nylon or elastic threads or special seams),
turn the graduated screw with the screwdriver. The
graduation marks make it easy to reset the universal
tension position.
