speed

As previously mentioned, the speed of this machine at the maximum

zigzag width of throw of 12m/m(15/32") is ,1700 stitches per minute and

when the zigzag width is less than 10m/m{25/64''), it can embrioder at the

speed of 2,000 stitches per minute.

The rotation of the machine determines the sewing speed. The number

of rotation varies with the electric cycle and the diameter of the motor

pulley.

quietly.

(B)

Leather

belt

Normally, this machine uses a leather belt, but following should be

observed:

(1)

Should not be too tight. At first, the leather belt is very stiff, so

often it is liable to be too tight- When it's too tight, the machine will

vibrate.

(2)

Joining

of the belt. Normally,

the

belt is joined with a wire.

When the joining is out of alignment or when the wire is sticking out, the

machine

cannot

run

smoothly.

(3)

Positions of

hand

wheel

and

puUcy- Unless the

hand

wheel

and

pulley are in correct positions, the belt might be curved or twisted, hampering

the quiet running of the machine. In such cases, move the motor position

and

correct

them.

Bobbin

winder

spool

For

the convenience of packing, the needle thread guide pin

and

the

bobbin winder spool pin are removed from the machine and packed sepa-

ratery

in a vinyl bag.

The

needle

thread

guide

can

be lightly

tapped

and

inserted.

and

it will come off.

Then
