11. To prevent fires, periodically draw out the power plug from the plug socket and clean
the root of the pins and the space between pins.
12. Do not turn OFF the power switch while the machine is in operation.
13. Hold the upper side of the machine head with both hands and perform the work quietly
so as not to allow your fingers or the like to be caught in the machine when tilting the
machine head or returning it to the home position.
14. Be careful that any load is not applied to the operation panel section.
1. To avoid electrical shock hazards, neither open the cover of the electrical box nor
touch the components mounted inside the electrical box.

iii
CAUTION BEFORE OPERATION
• Remove the air-vent cap (red color) attached to the sewing machine bed.
• Be sure to fill the oil tank with oil before use.
•Remove the needle bar stopper.
• Clean the sewing machine thoroughly before using it for the first time.
•Remove all dust collected on the sewing machine during the transportation.
•Confirm that the voltage and phase are correct.
• Confirm that the power plug is properly connected.
•Never use the sewing machine in the state where the voltage type is different from the designated
one.
•The direction of rotation of the sewing machine is counterclockwise as observed from the
handwheel side. Be careful not to rotate it in reverse direction.
•Do not tilt the machine head toward this side since oil leakage or parts breakage occurs.
•Asafety switch is installed so that the sewing machine cannot be operated with the machine
head tilted.
When operating the sewing machine, turn ON the power switch after properly setting the head on
the table.
•Before starting a test run, remove the bobbin case and the needle thread from the machine.
•For the first month after set-up, use the machine at a reduced sewing speed of 3,000 rpm or less.
•Operate the handwheel after the sewing machine has totally stopped.
WARNING :
To avoid malfunction and damage of the machine, confirm the following.

4. INSTALLATION
4-1. Installation of the sewing machine head
WARNING :
• Perform the installation of the sewing machine by the technical personnel who have been trained.
• To prevent personal injury, ask our dealer or the electrician for electric wiring.
•Be sure to perform the work with two persons or more when transporting the sewing machine and use a
lorry when moving it.
•To prevent personal injury caused by abrupt start of the sewing machine, do not connect the power plug
until the set-up of the sewing machine is completed.
• Be sure to earth the ground wire to prevent personal injury caused by leak.
•Be sure to attach safety protection cover, figer guard, etc.
■Installing the under cover
1) The under cover should rest on the four corners of
the machine table groove.
2) Fix two rubber seats 1on side A(operator’s side)
using nails 2as illustrated above. Fix two cushion
seats 3on side B(hinged side) using a rubber-
based adhesive. Then place under cover 4on the
fixed seats.
3) Remove air vent cap 5attached to the machine
bed. (Be sure to attach cap 5when transporting
the machine head in the state that the machine head
is removed from the machine table.)
If the sewing machine is operated
without removing air vent cap 5, oil
leakage from gear box portion 7
may occur.
4) Fit hinge 1into the opening in the machine bed,
and fit the machine head to table rubber hinge 8
before placing the machine head on cushions 3
on the four corners.
5) Attach head support rod 6to the machine table.

4-4. Adjusting the height of the knee lifter
1) The standard height of the presser foot lifted using
the knee lifter is 10 mm.
2) You can adjust the presser foot lift using knee lifter
adjust screw 1.
Do not operate the sewing machine
in the state that presser foot 3is
lifted by 10 mm or more since needle
bar 2and presser foot 3, or wiper
4and presser foot 3come in
contact with each other.
4-2. Removing the needle bar stopper
Remove needle bar stopper 1for transportation.
Keep the needle bar stopper which has
been removed, and install this needle
bar stopper when transporting the
sewing machine.The needle bar
stopper may be cut when it is strongly
drawn out. Slightly move the needle bar
to the right or left and slowly draw out
the needle bar stopper.
4-3. Attaching the knee-lifter
Insert knee-lifter into attaching hole 2and tighten it
with bolt 3.
*Adjust the position of knee lifter pad 1to a
convenient place. For the reference dimension, the
position is 220 mm from the bottom face of table.
*In case of the machine with AK device, knee lifter
pad 1is optional. (Part No. 22934251)
