I. CAUTIONS BEFORE OPERATION
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 sewing machine is lled with the predetermined amount of oil.
2. Never operate the machine unless the lubricating part in the hook 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 com-
pressed 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 order to prevent the optical ber sensor of the bobbin thread remaining amount detecting de-
vice from showing a detecting failure, be sure to clean thread waste around the hook using an air
gun once or more times a day.
7. In order to protect the ap sensor from showing a detecting failure, be sure to clean dust on the
reecting tape of the folding plate using an air gun once or more times a day.

5. CONNECTING THE POWER PLUG
Connection of the power plug to the power depends on the specications of the product. Adjust the power
plug to the power specications to connect.
① In case of the product of single-phase, 220 to 240V specications :
Connect the sky-blue and brown wires of the power cord to the power terminal (AC220 to 240V) and the
yellow/green wire to the ground (earth) terminal respectively.
② In case of the product of 3-phase, 200 to 240V specications :
Connect the red, white and black wires of the power cord to the power terminal (AC200 to 240V) and
the yellow/green wire to the ground (earth) terminal respectively.
③ In case of the product with the optional high voltage transformer (with SA-128) :
Connect the black wires (3 pieces) of the power cord to the power terminal (AC380 to 415V) and the
yellow/green wire to the ground (earth) terminal respectively.
It is possible to connect to 380/400/415V by setting of the input tap of transformer (standard setting at
the time of delivery : 380V).
CAUTION :
To prevent possible accidents caused by leakage or dielectric strength, an appropriate power plug
shall be installed by a person who has an expert knowledge of electricity. Be sure to connect the pow-
er plug to the receptacle that is well grounded.
This product performs operation by the single-phase connection for 3-phasse 380/400/415V.
[ Caution when changing the power source of the high voltage optional transformer ]
When using high voltage optional transformer ❶with
the input voltage of 400V or 415V, it is necessary to
replace input power source cord ❷ of high voltage
optional transformer ❶. Change power source input
cord ❷ (sky blue) that is connected to 380V to the
connection of 400V or 415V.
To prevent accidents, perform the work
after leaving the sewing machine alone
more than 4 minutes in the state that
the power switch is turned OFF and the
power cord is drawn out.
High voltage optional transformer ❶is set on the
rear side of the table.
When performing changeover of voltage, remove
transformer box ❹ after removing top cover ❸.

7. INSTALLING SP-46N (CLAMP BAR STACKER)
(OPTIONAL PART NO. : 40149301)
Clamp bar stacker is delivered in the
state that it is xed in the frame at the
time of delivery with the clamp bar
stacker mounted. It is necessary to
change the installing position to the nor-
mal using position.
① Remove stacker xing plate ❶.
② Turn the whole stacker in the direction of the
arrow and take it out from inside of the frame.
③ Change stacker turning shaft Asection to
stacker base hole B.
At this time, take care to prevent the stacker cord, the air piping, etc. from being caught.
In addition, insert the stacker rotating shaft into the hole in the stacker base until the bottom of
the base is reached.
④Lock the whole stacker with hinge ❷.
⑤ Insert safety bar ❸in direction Cas illustrated
in the gure. Fix the safety bar at the position
where it is in parallel with the oor surface.
At this time, conrm that air is being
supplied.

"Stacker in the setup state (without the
air supply)".
Then, start supplying the air after check-
ing to make sure that the stacker is in
the setup state.
In the case of power interruption due to
a power failure, etc., the folding opera-
tion of the stacker can get out of order.
Be aware that this can give rise to a risk
that the hand is caught in the stacker.
Do not put hands in the area surrounded
by the safety bar.

② Fill the oil tank with the oil until the top end of
oil amount indicating rod ❸comes between
the upper engraved marker line and the lower
engraved marker line of oil amount indicating
window ❷.
When oil amount is excessively large, oil leaks
from the air hole or adequate lubrication cannot
be performed. So, be careful.
③
When operating the sewing machine and the top
of oil amount indicating rod ❸has lowered up to
oil amount indicating window ❷, start lubricating.
To prevent entering of dust, be sure to
attach the cap for use.
CAUTION :
1. To prevent accidents caused by abrupt start of the sewing machine, do not connect the power
plug until lubrication has been completed.
2. To prevent inammation or rash, immediately wash the part when oil has stuck to your eyes or
body.
3. If oil has been swallowed, diarrhea or vomiting may occur. Put oil to the place where children can-
not reach.

• At the time of initial lling, ll the oil
tank with oil of 200cc as the standard
and conrm that the oil amount indi-
cating rod is working.
• When operating a newly installed
machine or a machine which has not
been used for a relatively long period
of time, make the machine run at 2,000
sti/min or less for the purpose of
break-in. In addition, use the machine
after applying oil to races Aof the
right/left hooks.
• For the oil for hook, purchase JUKI
MACHINE OIL No. 1 (Part No. : MD-
FRX1600C0).
• Be sure to ll the oil tank with clean
oil.
• Never ll the oil tank with dirty oil.

❺(Caution when operating)
When using the interlining supplying device with
rear reference ❺, the interlining at the sewing
start remains long since it is away from interlin-
ing outlet ❻. So, use the device with front refer-
ence ❼.

V. PREPARATION OF THE SEWING MACHINE
1. HOW TO OPERATE THE SEWING MACHINE HEAD
(1) How to attach the needles
Needles used are DP X 17 #14 to #18 (standard
#16). Use the specied needle.
Insert left- and right-hand sides needles as far as
they will go pointing their long grooves ❶at each
other and tighten needle clamp screws ❷.
❷❷
• Use the left hand twist thread for the needle
thread.
• Either twist thread will do for the bobbin thread.
(2) Thread used
Right hand twist thread
Left hand twist thread
Use a new thread which is uniformly
twisted.
❶
CAUTION :
• Turn OFF the power before starting the work so as to prevents accidents caused by abrupt start of
the sewing machine.
• When replacing the needle, be careful not to allow your ngers to touch the blade section of the
center knife.
