3. Installation  
DANGER  
Embroidery machines should be installed only  
by trained engineers.  
Install a machine in a place away from a high-  
frequency welding machine or other machines  
that may generate a strong electric noise. Fail-  
ure to do so may cause the embroidery machine  
to malfunction.  
Electric wiring should be laid by your distribu-  
tor or electric experts.  
A machine weighs more than 720 kg. Installa-  
tion should be carried out by 4 or more work-  
ers.  
Establish grounding as designated. Improper  
grounding may result in an electric shock.  
Do not connect the power source until installa-  
tion is completed. Doing so may start the ma-  
chine unintentionally through an accidental  
activation of the START switch, resulting in  
bodily injuries.  
* After installation is completed, get the power supply from a dedicated outlet.  
* When connecting multiple machines, exercise care not to exceed the capacity of the outlet.  
3-1 Transportation of Machine  
When relocating the machine, push the steel frame.  
Note) Never push the cover or carriage.

3-2 Installation of Machine  
1. Place the attached cushion sheets w and  
leveling plates e under the four level  
adjusters q. The leveling plates e should  
be placed above the cushion sheets  
respectively.  
2. Secure the four level adjusters q on the  
ground using the nuts r so that the  
machine will be stable.  
Note) If the floor is not strong enough, the embroi-  
dery machine may be rocked during opera-  
tion. In such a case, it is recommended that a

Chapter 6 Operation of Machine  
The machine head whose MENDING lamp is lit performs embroidering by the preset number stitches.  
When it is completed, all the machine heads start normal embroidering operation.  
• The MENDING lamps except for the machine  
head whose needle thread has been broken  
are turned off.  
• At this time, the machine head, whose  
MENDING lamp is on, performs resewing from  
the step-back position while the other machine  
heads (with MENDING lamps off) are stopped.  
When resewing is completed, the other  
machine heads (except those halted or with  
bed retracted) also start embroidering.  
■ Manual operation  
The mending start and end positions can be set for each machine head using the MENDING switch on the  
tension plate.  
The MENDING lamp is lit when the MENDING  
switch of each machine head is flipped up  
during standby. Resewing from the step-back  
position to this position can be executed.  
* When the MENDING switch is flipped up while  
the MENDING lamp is off, the lamp is turned  
on; when the MENDING switch is flipped up  
again while the MENDING lamp is lit, the lamp  
is turned off.  
Note) The mending end position cannot be set for each  
machine head.  
When all MENDING lamps are turned on, the  
mending end position will be set to the position  
where one of the lamps is turned off first.  
Note) To cancel the mending end position, turn all the  
MENDING lamps are turned on (except for halted  
machine heads) .

4. Jog Embroidering  
• Jog embroidering can be used for preventing  
the thread from slipping from the needle at the  
start of embroidering.  
• Jog embroidering can be executed as long as  
the start switch at the machine head is held  
down.  
Note) Never apply a tape on the switch to keep jog op-  
eration for a long time. Doing so may cause dam-  
age to the machine.  
5. Hoop Feed Position  
• In order to ease mounting and dismounting of the embroidery hoop, another needle position can be  
set as a hoop feed position in the movable area additionally to the current needle position.  
• In order to ease material attachment while operation is suspended, the hoop can be moved to the  
feed position at any time by the hoop feed switch.  
• The hoop can also be moved to the feed position automatically after embroidering is finished. Refer  
to "Hoop Automatic Retract" on Page 105 for details.
