!. 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.

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

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.
