can

be

reversed by turning the plug of the motor at

180

deg.

(4) Adjust the tension

of

arm

and

Loosen

the screw (A) of the

knee

To

thread the needle

thread,.

raise

the

needle

bar

to the upper

end

of its stroke,

lead

the thread from the spool

and

perform.

threading

as

shown

in

Fig9

.

To

draw the

bobbin thread, hold the end of the needle

thread

and

turn the

balance·

wheel to lower

the needle

bar

and

then lift it to its highest

position.

Pull

WINDING

INSTALLATION

AND

ADJUSTMENT(Fig. 10)

The

bobbin winder pulley should Align

with the V - belt

and

there should

be

some

clearance between them . When the bobbin

winder stop latch lever

is

depressed, the

V-

belt should

be

in

touch with the bobbin

winder bulley

in

order that the bobbin winder

pulley

can

be

driven

by

the V - belt.

The

thread wound

on

the bobbin should

be

neat

and

tight if not tight , adjust the

winding tension

by

turning the tension stud

nut (A) of the bobbin winder tension bracket,

when the thread wound

on

the bobbin does

not present a cylindrical

shape

as

shown

in

Fig.

10

(a), Loosen the set screw(

B)

of the

bobbin winder tension bracket

and

move the

bracket (C) leftward or rightward, if the thread

is

wound

as

shown

in

the figure (b), move

the bracket leftward

or

rightward of wound

as

shown

in

the figure(c) , move it leftward .

After positionting the bracket adequately,

tighten the set screw (B)

Do

not overfill the bobbin,

The

optimum

wound length of the thread will

fin

about

80% of the bobbin capacity .

This

can

be

adjusted

by

the screw(E) of the bobbin

winder stop latch.

ADJUST

THE

PRESSURE

OF

PRESSER

FOOT(

Fig.

)

Pressure of the presser foot

is

adjusted

in

accordance with thickness of materials to

be

sewn.

First loosen the lock nut

(A),

for

heavy

materials, turn the pressure regulating thumb

screw

as

shown

in

Fig.

11

(a) to increase the

pressure I while for light materials, turn the

pressure regulating thumb screw

as

shown

in

Fig.

(b) to decrease the pressure , the

tighten the lock nut (A),

The

pressure of
