WINDING

INSTALLATION

AND

ADJUSTMENT(Fig. 10)

The

bobbin winder pulley should Align

with the V - belt

and

there should

some

clearance between them . When the bobbin

winder stop latch lever

depressed, the

V-

belt should

touch with the bobbin

winder bulley

order that the bobbin winder

pulley

can

driven

and

tight if not tight , adjust the

winding tension

turning the tension stud

nut (A) of the bobbin winder tension bracket,

when the thread wound

the bobbin does

not present a cylindrical

shape

shown

Fig.

(a), Loosen the set screw(

of the

bobbin winder tension bracket

and

move the

bracket (C) leftward or rightward, if the thread

wound

shown

the figure (b), move

the bracket leftward

rightward of wound

shown

the figure(c) , move it leftward .

After positionting the bracket adequately,

tighten the set screw (B)

not overfill the bobbin,

The

optimum

wound length of the thread will
