1. GENERAL
Conventionally, a series of operations including the replacement of bobbin in the sewing machine hook,
removal of thread remaining on a bobbin, winding of a bobbin, threading of bobbin case tension spring,
and trimming of thread have been carried out manually. Now, this device has been developed to carry
out the series of operations full-automatically. This device not only helps increase efciency of sewing
work but also achieves stable product-making in the process that requires high-quality seams.
Refer to the Instruction Manual for the AMS-224EN4530R/IP-420 for the main body of sewing machine.

For the 6030, the table has been retracted from the normal position in the factory in prior to ship-
ment.
After unpacking, be sure to carry out the following steps 1) through 9).
DANGER :
The power cable passes through inside the cover. The terminal block is also installed inside
the cover. Be sure to turn the power OFF before starting the installation work in order to protect
against accident caused by electric shock.

that the table protrudes equally (approximately 3
mm on each side) from the end of table stand.
* If the table is not correctly positioned in the
longitudinal direction, the throat plate auxiliary
cover may not be removed.
4) Temporarily x table xing bolts ❸ at two loca-
tions from the table stand side.
5) Tighten screws ❶ and ❷ to mount the cover.
* If the cover and tapped hole do not align, align them
by moving the table.
* Tighten screw ❷ after mounting the nut from the
underside of the table.
6) Securely tighten the table xing bolts at two

3-2. How to thread the device with the bobbin thread
In order to accurately measure the length of thread from the bobbin thread cone ❶ to be wound on a
bobbin, guide the thread from the bobbin thread cone ❶ through the bobbin thread feeding unit and
draw the thread out from the nozzle as illustrated in the gure.
Install the spool holder disk to the lowest possible position. If it is installed at a high position, an excessive tension will be applied to the thread drawn from the bobbin thread cone ❶, causing a trouble.
