REGULATING

THE

THREAD

TENSION

For

ordinary

stitching,

the

tension

of

the

upper

and

lower

thread

should

be

equal

so

as

to

lock

both

threads

in

the

center

of

the

fabric.

The

tension

of

the

bobbin

thread

is

regulated

by

means

of

the

tension

screw,

but

it is

preferable

to

keep

it

rather

weak.

Once

it

is

regulated,

the

perfect

stitch

can

be

obtained

by

adjusting

the

tension

of

upper

thread

by increasing

or

decreasing

the

tension.

REVERSE

depressed

as

long

as

requir

ed

and

if

release

the

lever,

ordinary

stitch

will

be

done.

(For all

other

forward

stitching,

the

lever

remains

in

the

up

position
