Usually
any
incorrect
tension
will
be
experienced
on
the
upper
thread.
Therefore,
any
necessary
alteration
should
be
carrier]
out
there
first,
but,
should
this
not
bring
about
(in
imorOvCmcnt,
the
under
thread
tension
should
be
acl

usted.
Satisfactory
stitching
can
ho
ohtuinecf
only
ii
upper
and
under
thread
tensions
are
correct.
After
you
hrive
sewn
a
few
inches
check
the
stitching
on
top
and
underneath.
The
tensions
are
satisfactory
if
both
threads
are
drown
in
eualfy
cind
lock
in
tfse
centre
of
the
work
(Fig.
10).
If
however
stitches
loop
on
the
underside
of
the
work
(Fig.
11)
the
upper
thread
is
too
slack,
and
must
be
given
more
tension
by
turning
the
thumb
nut
to
the
right,
i.
e.
in
ci
clockwise
direction.
If
after
adiusting
the
upper
thread
tension
the
loops
continue
to
he
formed
an
the
underside
of
the
material,
it
is
possible
that
the
under
thread
lbs
been
tensioned
too
severely,
and
you
must
slacken
it
off
a
little
by
turning
the
small
screw
i/
(Fig.
7)
slightly
to
the
left,
.
e.
in
on
anti-clockwise
direction.
Loops
forming
on
top
of
the
material
(Fig.
12)
may
be
owing
to
excessive
upper
thread
tension.
Correct
the
tension
by
turning
the
thumb
nut
on
tension
discs
to
the
left.
Only
if
none
of
the
above-named
odtustments
corrects
the
stitch-forming,
should
the
under
thread
be
given
more
tension,
by
turning
the
screw
i/
(Fig.
7)
to
the
right.
Regulating
the
Pressure
on
Material
The
presser
bar
is
set
at
normal
pressure
which
will
be
found
satisfactory
and
ensure
a
steady
feed
when
work
ing
on
light
rind
medium
weight
materials.
Only
when
sewing
exceptionally
heavy
or
hard
materials
is
greater
pressure
required.
To
increase
the
pressure
the
adjust
ment
screw
on
top
of
the
bar
must
be
turned
clockwise.
Anti-clockwise
adlustment
reduces
the
pressure.
Removing
the
Work
from
the
Machine
Move
the
needle
to
its
highest
point,
raise
the
presser
bar
lifter,
and
draw
the
material
to
the
bock,
clear
of
the
needle.
Now
sever
the
threads,
leaving
them
about
3’
long
at
the
back
of
the
presser
foot,
and
ready
for
the
next
sewing.
