■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
4 on the xed 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 with-
out removing air vent cap 5, oil leakage
from gear box portion 7may occur.
4) Fit hinge 1into the opening in the machine bed,
and t 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.
(However, this step is not necessary for the ma-
chine with AK 9device.)

4-4. Adjusting the height of the knee lifter
1) The standard height of the presser foot lifted us-
ing 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 3 is 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 sew-
ing 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 nee-
dle bar stopper.
4-3. Attaching the knee-lifter
Insert knee lifter pad 1into attaching hole 2and

Put power cable from hole B of the power switch, and
securely x green/yellow cord to 9, white cord to 6,
black cord to 7and red cord to 8with screws.
¡In case of single phase power cable
Put power cable from hole B of the power switch,
and securely x green/yellow cord to 9and other
cords to 6and 7with screws. 8is not used.
4) Installing the power switch cover
Securely tighten screw 1located on the side of
the power switch.
4-7. Installing the operation panel (IP-110)
