stud J2 so that extension M2 enters
hole in machine, ind tail (inside the
coil) of thread tuke-up spring enters one
of grooves in the stud.
Next, replace indicator Z with the
large open side facing end of stud (out-
ward) so that the plus and minus signs
can be: readily seen from a sewing
osition. Insert tension spring D2 in
indicator so that first half turn E2 of
this spring will enter slot in tension
stud. Guide stop washer C2 onto stud
so that extension N2 will be above
tension stud as shown in Fig. 27.
Next place numbered dial on stud so
that numeral 2 is opposite stop washer
extension N2, then push dial to com-
press spring so that thumb nut can be
turned onto stud, carefully guiding pin
in thumb nut into one of holes in num-
bered dial. Lower presser bar and turn
thumb nut A2 to left until it stops at
27
“O''. Thread the tension with size 50
mercerized cotton and pull thread
through tension discs to test amount
of tension at ‘‘0"' position. At this
int there should be a barely percepti-
ble pull on thread to indicate that there
is a minimum tension, which will grad-
ually increase with the turn of thumb
nut to right, a Meee ¢ a full range of
tensions from light to heavy within one
revolution of thumb nut. If pull is too
strong for a minimum tension, press in
numbered dial Y, to disengage pin B2
in thumb nut from dial pn pin in
one of holes to left of previous setting.
This resetting of pin will produce less
tension at zero. On the other hand,
should there be insufficient tension at
zero, press in dial Yand reset pin B2 in
one of holes to right of previous setting.
Repeat this process until the desired
minimum tension is obtained.
