!. Machine (about the sewing machine)
Following items have to be checked every working day before the operation of the machine and before the start
of work hours.
1. Ascertain that the oil pan is lled with the predetermined amount of oil.
2. Never operate the machine unless the oil pan has been lled up with oil.
3. Ascertain that the pressure gauge indicates the designated air pressure of 0.5 MPa.
* (This is necessary particularly when the compressor is stopped for a lunch break or the
like.)
If the compressed air pressure is equal to or less than the designated value, troubles such
as interference between the parts can occur. It is therefore necessary to carefully check the
compressed air pressure.
4. Check whether the needle thread/bobbin thread need to be replenished.
5. To perform sewing immediately after turning ON the power switch, perform trial stitching
rst, then proceed with sewing of actual products after the test sewing.
6. In the case drainage water accumulates in the regulator section, expel it from there before
starting work.
Precautions for use

1. The range of belt-loop feeding length (the entire length of a belt-loop shown on the
operation panel) is from 58 mm to 130 mm. If the belt-loop feeding length exceeding the
aforementioned range is set, an error will occur.
2. In the case "distance B + distance D" exceeds 66 mm when using No. 4 or No. 5 patter,
an error will occur.
3. The dimensions of the belt loop sewing shape displayed on the operation panel are
only for reference. The dimensions vary according to the belt-loop material. Be sure to
adjust the settings of belt loop dimensions so that your desired nished dimensions
are achieved.

2-4. Garment body presser/work clamp foot specications
Garment body presser 1and 2for securing the
garment body is provided as standard with auxil-
iary clamps 3, 4, 5and 6.
Be aware that the auxiliary clamps 3may be
required to be removed according to the sewing
shape of the belt-loop.
In the case of two kinds of sewing shapes; No. 2
and No. 6, auxiliary clamp 3has to be removed.
Loosen two screws 7and remove the auxiliary
clamps 3from the garment body presser 1.
(1) Garment body presser
If you have changed the garment body presser,
set the machine setting N802 according to the
garment body presser actually being used.
A Additional clamp is provided
B Additional clamp is not provided

1. For belt loop shapes Nos. 5 and 7, auxiliary clamps 4and 6are damaged since they
are rubbed by the fork pin which rolls the belt loop. If the auxiliary clamps are heav-
ily damaged, they can deform or break. It is necessary to periodically change auxiliary
clamps with new ones.
2. Install the auxiliary clamps at right angles to garment body pressers 1and 2. Be sure
to check that the auxiliary clamps do not interfere with other parts.

The work clamp foot of the sewing machine for lin-
ear bartacking is mounted as standard.
It is used when liner bartacking is used for sewing
various kinds of belt loops.
Be aware that, to carry out zigzag bartacking, the
currently installed work clamp foot and the feed
plate have to be replaced with those for zigzag
bartacking, and zigzag bartacking has to be set on
the operation panel.
In addition, when the work clamp foot for zigzag
bartacking is installed, auxiliary clamp 3has to
be re-positioned accordingly by loosening two
screws 7 as shown in the gure at the left. (Re-
fer to "!-2-4 (1) Garment body presser/work
clamp foot specications", p.5.)
(2) Work clamp foot of the sewing machine
If you have changed the work clamp foot of the
sewing machine, set the machine setting N801
according to the work clamp foot actually being
used.

3-2. Fixing the machine
Connect air coupler 1supplied with the unit as
an accessory to air hose 2. Then, connect the air
coupler to coupler 3on the main body side.
3-3. Connecting the air coupler
1. After having connected coupler 1
with air cock 4closed, carefully
open air cock 4to supply air.

CAUTION :
1. In order to protect against accidents causing personal injury or death, move the
machine to a level and stable place and secure it by lowering adjuster bolts 2(at four
locations) placed at the side of casters 1.
2. When adjusting the leg height of the sewing machine, the leg xing bolts 3need to be
loosened to move the leg up or down. When the xing bolts have been loosened, there
is a danger for the legs to suddenly drop down. Therefore, be careful when loosening
the bolts.

3-4. Connecting the power plug
The method to connect the product to the power source differs by the product specications. Be sure to
connect the product to the power source according to the power specications.
1For the single-phase, 200 - 240 V type product
Connect the sky-blue/brown wire of the power cord to the supply terminal (200 - 240 VAC) and the
yellow/green one to the earth terminal respectively.
2For the 3-phase, 200 - 240 V type product
Connect the red/white/black wire of the power cord to the supply terminal (200 - 240 VAC) and the
yellow/green one to the earth terminal respectively.
3For the product provided with an high-voltage optional transformer
Connect the black wires (three) of the power cord to the supply terminal (380 - 415 VAC) and the
yellow/green wire to the earth terminal respectively. The product can be connected to 380/400/415
V power terminals according to the setting of the input tap of the transformer. (Standard setting at
the time of shipment: 380 V)
4 In the case the single-phase, 200 - 240 V type product is modied to the 3-phase, 380/400/415 V
type one
Optional parts are required.
• High-voltage optional transformer Parts No.: 40005422
• Power cord Parts No.: 40070548
In the case of the 3-phase, 380/400/415 V power supply, this product is operated under the
single-phase connection state.
[Precaution to be taken when changing the power of the high-voltage optional transformer]
To use high-voltage optional transformer 1with
the input voltage of 400 V or 415 V, you need to
replace input power cord 2of high-voltage op-
tional transformer 1correspondingly. Change
power input cord 2(brown) which is connected to
the 380 V power terminal with the one for 400 V or
415 V connection.
In order to protect against accidents,
the aforementioned work should be
carried out after having left the sewing
machine for 5 minutes or more with
the power switch turned OFF and the
cord removed.
High-voltage optional transformer 1is placed on
the side face of the control box.

CAUTION :
In order to protect against accidents caused by a ground fault or dielectric voltage, be
sure to have the adequate power plug mounted by a person who has electrical expertise. It
is also important to connect the power plug to the grounded receptacle.

[How to install the high-voltage optional transformer (part number: 40090561)]
1) Loosen four screws on the front side of emer-
gency stop switch 1. Open the switch box.
Remove the power cord (brown, sky blue,
yellow/green wires) from the secondary side
(on the side 2is printed).
2) Connect the power cord to the optional trans-
former. Connect the power cord (40005423:
Three-wire cord) supplied with the unit to the
optional transformer.
Brown wire →380/400/415 V (according to
the power specications)
Blue wire →0 V (next to the 380 V)
Yellow/green wire →E (on the ring terminal side)
Connect the cord on the control box side (the
cord which has been removed in Step 1).
Brown wire →220 V
Sky blue wire →(next to the E)
Yellow/green wire →E
3) Install optional transformer on the side face
of control box 2. Refer to "HIGH VOLTAGE
TRANSFORMER SETUP INSTRUCTION
(40005426)" for connecting procedure.
4) Connect the power cord supplied with the unit
to emergency stop switch 1.
Brown wire →2-1
Sky blue wire →2-2
Yellow/green wire →E
(Brown and sky blue wires respectively have a
fork terminal.)
5) Re-tighten the four screws of emergency switch
1. Take care not to leave a gap in the switch.
