This device uses two bobbin cases each of which is fitted with a bobbin.

4-5-2. How to fit a bobbin in the bobbin case

Fit a bobbin in the bobbin case so that clutch
holes

❶

(at two locations) of bobbin are brought

to the open side.

Before fitting a bobbin in the bobbin
case, wipe the bobbin case to remove
oil and dust. In particular, wipe the
shaft section of bobbin case to re

move oil and dust. In addition, blow
out, with an air gun, oil and dust gath

ering under the bobbin idling preven

tion spring in the bobbin case.

When the thread is put in thread path tube

❽

it is sucked. Put the thread in the tube, while
pulling the thread from the bobbin thread
cone, until the length of thread coming out of
the tip of nozzle

becomes approximately

13 cm. If the thread stops halfway, pull it back
slightly several times.

At this time, the bobbin winder nozzle is at
its advanced position. In this state, adjust the
length of thread while observing the scale on
label

as a guide.

❶

7) Suction is stopped by pressing

again.

Basically, adjustment of the thread tension controlled by the thread tension controller is not required.
