Adjusting Pressure
The pressure dial regulates the
pressure that the presser foot ex-
erts on the fabric . Correct pressure
is important because it means the
fabric feeds smoothly and evenly,
without being marred . Generally,
heavier fabrics require a high num-
ber setting (heavier pressure) ;
lightweight fabrics, a lower setting
(lighter weight pressure) . But fab-
ric texture must also be considered ;
soft fabrics, for example, require
less pressure than crisp fabrics .
When darning without an embroi-
dery hoop, you should set the dial at
the lowest setting, D.
" Lower the presser foot .
" To increase
pressure, turn dial to
higher number.
" To decrease
pressure, turn dial
to lower number.
Adjusting Feed Height
The feed can be placed in any one
of three positions-R, F, or D-by
rotating the feed regulating knob.
R (Regular) is used for sewing on
most fabrics. The feed is raised
to its highest point.
-F (Fine) is used for sewing on deli-
cate or lightweight fabrics such
as silk, batiste, crepe, and fabrics
that will mar easily . The feed is
lowered slightly .
D (Darn) is used for free-motion
darning and embroidery and
button sewing. The feed is low-
ered below the throat plate and
does not move the fabric .
Raise the presser foot .
Turn the feed regulating knob to
align R, F, or D with index mark .
