3. INSTALLATION
DANGER :
1. The sewing machine should be installed by a trained technician.
2. Contact the distributor or a professional electrician to ask him/her to carry out electric wiring.
3. The sewing machine has a mass of approximately 110 kg. Four or more workers are required
to carry out the installation of the sewing machine and adjustment of the table height.
4. Never connect the power plug until the installation of the sewing machine is completed in or-
der to protect against an accident due to an abrupt startup of the sewing machine.
5. Be sure to ground the earthing wire in order to protect against an accident due to electrical
leakage.
6. Be sure to raise/return the sewing machine from/to its home position by holding it with both
hands.
7. Do not apply an unreasonable force to the sewing machine when it is in the raised position. If
such a force is applied, the sewing machine can lose its balance to fall alone or fall together
with the table, resulting in personal injury or sewing-machine breakage.
3-1. Table
• Use the table and stand which are able to withstand the sewing machine mass (110 kg) and vibration.
The table thickness of which is 40 - 60 mm should be used.
• Use the table stand which has an appropriate height for the sake of the operator's ease of use.
• The xing bolt for xing the table and the stand should be of the length which matches the thickness of
the table.
1. In the case the table thickness exceeds 60 mm, the length of the bolts supplied with the unit
as accessories is adequate.
2. In the case the xing bolt for xing the table and the stand is too long for the table thickness,
unexpected injury to hands or head can occur.

3-2. Installing the control box
Install control box 1to the location illustrated in the
gure using four bolts 2, four plain washers 3and
four spring washers 4and four hexagonal nuts 5
supplied with the unit.
Install control box 130 mm or more away
from the stand. If control box 1is located
too close to the stand, the former can get
hot or the sewing machine can malfunc-
tion.
Bolt 2is a cup head square neck bolt (M8;
Length: 70 mm) and nut 5is a hexagonal
nut (M8).
3-3. Installing and connecting the power switch
1) Installing the power switch

DANGER :
1. The sewing machine should be taken out by a trained technician(s).
2. The sewing machine has a mass of approximately 110 kg. Four or more workers are required
to take out the sewing machine.
3. Do not apply an unreasonable force to the sewing machine until the installation of the sewing ma-
chine is completed. If such a force is applied, the sewing machine can lose its balance and can
fall alone or together with the table, resulting in personal injury or sewing-machine breakage.
4. Never connect the power plug until the installation of the sewing machine is completed in or-
der to protect against an accident due to an abrupt startup of the sewing machine.
3-4. Taking out the sewing machine
1) Remove accessory boxes 1and 2in the direc-
tion of the arrow.
2) Remove upper foam polystyrene 3in the direc-
tion of the arrow.
3) Remove the right and left intermediate foam poly-
styrene 4and 5in the direction of the arrow.
Place a cardboard sheet or packing material be-
tween the oor and the sewing machine in order
to avoid damaging the floor and to prevent the
cords from being pinched between the INT cover
and the oor.
4) Take out the sewing machine from the package, by four workers, holding the portions illustrated in the g-
ure. Place it on the oor.

DANGER :
1. Do not lift the sewing machine for any purpose other than for installation, repair or adjust-
ment in order to prevent accidents resulting in personal injuries due to pinching. In addi-
tion, the sewing machine has to be lifted for repair or adjustment only by a maintenance
technician who is familiar with the machine.
2. If you nd the sewing machine is too heavy to lift, the gas spring may have malfunctioned
due to outgassing.
Never lift the sewing machine in such a state since the machine can drop to pinch hands,
ngers and arms resulting in serious injury.
* Carefully read the description given in "10-14. (6) Standard of replacing time of the gas
spring" p. 88 and "10-14. (7) Replacing the gas spring" p. 89.
3. Be sure to carry out the work while strictly observing the following in order to protect
against serious injury to hands, ngers and/or arms due to pinching in the relevant parts of
the sewing machine.
• Be sure to hold the sewing machine by the ribs located on the front side of the bed.
• Be sure to securely x the sewing machine in the raised position by locking the hinge stopper.
4. Do hole hold any part other than the ribs located on the front side of the bed.
5. If you raise the sewing machine with the feed base remained this side, the feed base can
move to pinch hands and ngers resulting in an unexpected injury.
3-6. Raising and returning the sewing machine
The sewing machine can be raised/returned to/from four different heights.
1st step 2nd step
3rd step 4th step
WARNING :
When raising/returning the sewing machine from/to its home position, check to be sure that the
sewing machine is locked by the support shaft in the stop position of each step of the hinge
stopper.

– 11 –
1) To raise the sewing machine, firstly push feed
base 2 away from you (in the direction of the
arrow), then insert  at-blade screwdriver 4into
bottom-cover opening tool slot 3, turn it coun-
terclockwise to release the sewing machine up/
down lock 5.
2) Turn  at-blade screwdriver 4to keep the lock in
the released state, and slightly lift the sewing ma-
chine by holding it by rib 1located on the front
side of the bed.
3) Carefully remove  at-blade screwdriver 4. Hold
ribs 1and 1' located on the front side of the
bed with your both hands to slowly lift the sewing
machine to the 1st step of hinge stopper 6.
At this time, do not hold feed base 2and feed
guide shaft 8.
4) Check to be sure that hinge stopper 6is locked
by support shaft 7. Then, take hands off the ribs.
5) To raise the sewing machine to the 1st to 3rd
steps of the hinge stopper, hold ribs 1and 1’
located on the front side of the bed with your both
hands to slowly lift it to the required step of the
hinge stopper.

[To lift the sewing machine from the 3rd to 4th step of the hinge stopper]
6) Hold rib 1located on the front side of the bed with your right hand to draw hinge stopper 6in direction of
arrow A until the lock is released. Then, slowly lift the sewing machine.
7) Hold ribs 1and 1’ located on the front side of the bed with your both hands to slowly lift the sewing ma-
chine to the 4th step of hinge stopper 6.

DANGER :
1. Do not lower the sewing machine while keeping pulling the hinge stopper in direction A, in
order to prevent pining of  ngers, hands and arms under the sewing machine leading to a
serious injury. (Be sure to take your hands off the hinge stopper.)
2. Do not hold feed base 2and feed guide shaft 8.
DANGER :
Take care to prevent pinching of hands and  ngers between the sewing machine and the bot-
tom cover. It should be strictly prohibited to lower the sewing machine by two or more workers
while holding it by any section other than the ribs located on the front side of the bed since it
can cause a pinching accident resulting in a serious injury to hands,  ngers and/or arms.
8) To return the sewing machine to its home position,  rstly check to be sure that there is no tool such as a
screwdriver inside the bottom cover.
9) Hold rib 1located on the front side of the bed with your right hand to slightly lift the sewing machine.
Then, hold handle 6 of the hinge stopper with your left hand and pull it toward you (in direction A) until
the lock is released, then slowly lower the sewing machine.
10) Take your left hand off the stopper section. While supporting ribs 1and 1’ located on the front side of
the bed with your both hands, lower the sewing machine further.
11) At its each step, the hinge stopper is locked to secure the sewing machine at the corresponding height.
Following the procedure described in 9), hold rib 1on the front side of the bed with your right hand to
slightly lift the sewing machine. Then, hold the handle of the hinge stopper with your left hand to release
the lock and slowly lower the sewing machine.
12) The sewing machine is stopped again at the  nal step of its lowering for the sake of safety. Following the

Take care not to crack bottom cover 5
when driving in spring pin 7.
5) Make a knot in the oil wick 6 (φ2.5 mm). Insert
oil wick 6 (φ2.5 mm) into spring pin 7of bottom
cover 5until its end comes from oil drain cock 1.
At this time, insert oil wick 6 (φ2.5 mm) into the
slit in spring pin 7.
6) Install poly oiler 8on oil drain cock 1.
Refer to "3-6. Raising and returning the
sewing machine" p.10 when you raise or
return the sewing machine.
