2-2. Installation of the sewing machine
1) Carry the sewing machine with two persons.
In the case of the sewing machine with a thread
trimmer, loosen post cover mounting screws 󰿿
(three locations) to remove them. Remove post
cover 󱀀. Then, carry the sewing machine by
holding motor cover 󱀁.
2) Place the sewing machine on a horizontal and
plane place when placing it and do not place
any protruding thing such as a screwdriver or
the like.
Never hold the handwheel since it rotates.
3) Attaching the hinge seats and the support rub-
bers of the machine head
Fix accessory hinge seat 󰿿supplied with the
unit on the table with wood screw 󱀅and wash-
er 󱀆while placing sheet plate 󱀄between the
hinge seat and the table as shown in the gure.
Fix machine head support rubbers 󱀀and 󱀁on
the table with nails while putting sheets A(stan-
dard: 3 pieces) and sheet B(standard: 1 piece)
under the machine head support rubbers.
Use nail 󱀃for sheet Band nail 󱀂for sheets A.
There are two di󰀨erent machine head support
rubbers 󱀁; i.e., the rubber for the right and that
for the left. Be sure to check the types of the
support rubbers before xing them.
Sheet A (eight pieces) and sheet B (four pieces) are supplied with the machine as accessories.
For the sheet A, three sheets are to be used as standard for each mounting position. For the sheet B,
one sheet is to be used as standard. (The state shown in the left gure)
The sheets A and B are used for adjusting the height of the top surface of the bed. Use one more
sheet to increase the height, or use only one sheet to decrease it.
Be sure to use a short nail 󱀃 for sheet B. If long nail 󱀂 is used, the nail tip can penetrate the table
giving rise to a risk of injury.

11) Attaching the button tube
Attach the button tube to the cord so as to pre-
vent the cord from coming in contact with the
extension cord connector pin conductive sec-
tion.
Sag the sewing machine cord under the table.
Put button tube 󱢾(40102736, L = 450 mm)
over the cord.
Position the button tube so that the button of
button tube is brought to the rear side. In order
to prevent the button from slipping o󰀨, adjust so
that the button is brought to inside when bend-
ing the cord.
Tilt the machine head. Lift up the button tube
until it enters the machine head cover.
Secure the section between the top and sec-
ond-to-top button with accessory cable clip band
󱢿(HX00065000A, L = 200 mm) supplied with
the unit.
Take care not to allow the cable clip band to
enter the table when standing the machine
head as illustrated in the gure, in order to
prevent the band from being caught under
the table.

Also secure the lower section of the button tube
with a cable clip band.
Adjust the position of the cable clip band to the
upper side of the lowermost button. Also adjust
so that connection section 󱣀of the CN22 con-
nector locates above the cable clip band.
Also secure the end of button tube with cable
clip band 󱣁.
Check to make sure that no extra stress is ap-
plied to the cord when tilting the machine head.
Connect the cord to the specied PCB con-
nector (refer to "2-9. Connecting the cords"
p.12).

2-9. Connecting the cords
1) Loosen four setscrews 󱀀of control box cover 󰿿.
Remove control box cover 󰿿.
2) Connect the cords to the respective connectors
on CTL PWB, PWR PWB. (Fig. 1)
Secure cord 󱀃of pedal sensor with setscrew 󱀄
and cord clamp 󱀅. (Fig. 2)
3) Fix green/yellow ground wire 󱀂at position 󱤨of
the control box with a screw (Fig. 3). In addition,
for the EU type models, x the cable (Black) at
screw 󱤩with a screw.
DANGER :
1. To prevent personal injuries caused by electric shock hazards or abrupt start of the sewing machine,
carry out the work after turning OFF the power switch and a lapse of 5 minutes or more.
2. To prevent accidents caused by unaccustomed work or electric shock, request the electric expert or
engineer of our dealers when adjusting the electrical components.
Securely x the cords to be connected to
CN20, CN21 and CN22 with cable clamp 󱀁.
Check the connector markers of CN21 and

2-10 Handling the cords
1) Bring the cords under the table into the control
box.
2) Put the cord brought into the control box through
cord exit plate 󰿿 and x cable clip band 󱀀.
3) Install control box cover 󱀁with four setscrews
󱀂.
Arrange the cord so that it is not tensed
or hitched even when the machine head is
tilted. (See 󱤨 section.)
For the purpose of preventing the cord
breakage, take care not to allow the cords to
be caught between the control box and con-
trol box cover 󱀁 when attaching the latter.
DANGER :
1. To prevent personal injuries caused by electric shock hazards or abrupt start of the sewing machine,
carry out the work after turning OFF the power switch and a lapse of 5 minutes or more.

2-11. Attaching the connecting rod
1. If the screw is excessively loosened, the
spring will come o󰀨. Loosen the screw to
such an extent that the top of the screw
can be observed from the case.
2. Whenever you have adjusted the screw,
be sure to secure the screw by tightening
metal nut 󱀃 to prevent the screw from
loosening.
1) Fix connecting rod 󰿿to installing hole 󱤩of
pedal lever 󱀀with nut 󱀁.
2) Installing connecting rod 󰿿to installing hole 󱤨
will lengthen the pedal depressing stroke, and
the pedal operation at a medium speed will be
easier.
3) The pressure increases as you turn reverse de-
pressing regulator screw 󱀂in, and decreases
as you turn the screw out.
WARNING :
To protect against possible personal injury due to abrupt start of the machine, be sure to start the
following work after turning the power o󰀨 and a lapse of 5 minutes or more.

1. When using a new sewing machine for the rst time or using the sewing machine which has not
been used for a long time, run in the sewing machine at a sewing speed of 1,000 sti/min or less and
check the oil quantity in the hook before use.
In the case the oil does not come from the hook, turn the oil amount adjusting screw counterclock-
wise to make sure that the oil is fed from the hook. After that, adjust the amount of the oil fed from
the hook appropriately. (Refer to "4-12. Adjusting the oil quantity in the hook" p.36)
2. For the oil for hook lubrication, purchase JUKI NEW DEFRIX OIL No. 1 (Part No. : MDFRX1600C0) or
JUKI MACHINE OIL #7 (Part No. : MML007600CA).
3. Be sure to lubricate clean oil.
WARNING :
1. Do not connect the power plug until the lubrication has been completed so as to prevent accidents
due to abrupt start of the sewing machine.
2. To prevent the occurrence of an inammation or rash, immediately wash the related portions if oil
adheres to your eyes or other parts of your body.
3. If oil is mistakenly swallowed, diarrhea or vomitting may occur. Put oil in a place where children
cannot reach.
 Lubrication procedure
Fill the oil tank with oil before operating the sewing
machine.
1) Fill the oil tank with JUKI NEW DEFRIX OIL
No.1 (Part No. : MDFRX1600C0) or JUKI MA-
CHINE OIL #7 (Part No. : MML007600CA) using
the oiler supplied with the machine from section
󱤪.
2) Fill the oil tank with the oil until the top end of
oil amount indicating rod 󱀀comes between the
upper engraved marker line 󱤨and the lower
engraved marker line 󱤩of oil amount indicating
window 󰿿.
If the oil is lled excessively, it will leak from the
air vent hole in the oil tank or proper lubrication
will be not performed. In addition, when the oil
is vigorously lled, it may overow from the oil
hole. So, be careful.
3) When you operate the sewing machine, rell
oil if the top end of oil amount indicating rod 󱀀
comes down to the lower engraved marker line
󱤩of oil amount indicating window 󰿿.
