LOWER TENSION
ADJUSTMENT
If your machine skips stitches
or loops stitches, it may
require a tension adjustment.
To check bobbin thread ten­
sion, follow these steps;
(3) Push latches of the shuttle
race cover to the outside,
as shown in figure ®.
(D Remove shuttle cover as
shown in figure ®.
@ Remove the shuttle as
shown in figure
@ Suspend bobbin, bobbin
case, and shuttle all
together by thread as
illustrated in figure ®.
When jerking the thread
slightly, all of them should
slide down with light resis­
tance. If they do not slide
down with a slight jerk of
the thread, the bobbin
case tension is too tight. If
they slide down too easily,
the bobbin case tension is
too loose. See following
page for adjustment ot the
bobbin case. Once the
bobbin case is correclly
adjusted, it is easy to use
the upper tension to bal­
ance the stitches as
shown on page 12.
