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
without 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.
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,gerguard,etc.

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)
4-3. Attaching the knee-lifter
Remove needle bar stopper 1for transportation.
Keep the needle bar stopper which
has been removed, and install this
needle bar stopper when transporting

¡
When the input power cord of electrical box is 3P
Put 3P cord from hole A of the power switch and
securely x green/yellow cord to 5, brown cord to
2and sky blue cord to 3with screws.
3) Connecting the power cable supplied as accessories
¡In case of 3-phase power cable
Put power cable from hole B of the power switch,
and securely fix 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 (D))
1) Install operation panel 1on the machine head
using screws 3which have been assembled to
panel installing bracket 2.
4-6. Connecting the power switch cord (Japan and general export area)
1. Do not disassemble the operation
