INSTALLATION ENVIRONMENT
INSTALLATION ENVIRONMENT
CAUTION
Install the machine on a sturdy floor.
The floor structure must be strong enough to bear the machine
weight (indicated on the spec. plate).
Prevent the operation noise in the environment.
To prevent the sound insulation performance of the factory in
addition to the operation with reduced noise of this machine,
use the interior finish materials which show high sound insulat-
ing performance for the walls, ceiling, and floor of the factory.
Avoid direct sunlight.
If the machine is exposed to direct sunlight over an extended
period of time, the machine body may be discolored or
deformed. Put curtains or shades to the site to prevent the
machine from direct sunlight.
Provide enough space for maintenance.
For the maintenance purpose, provide at least 50 cm clearance
around the machine (at the right, left, and backsides of the
machine).
Avoid dust and moisture.
Dust and moisture lead to dirt and rust on the machine. Install
air conditioning equipment, and periodically clean the working
area.
Use caution not to expose the machine to direct wind from the
air conditioner so that the embroidery threads do not become
disheveled.
Humidity: 30 to 95%RH (relative humidity) without condensa-
tion
Ambient temperature: 5 to 40°C (during operation),
-10 to 60°C (during storage)

CAUTIONS ON MACHINE OPERATION

CAUTIONS ON MACHINE OPERATION
CAUTION
For long life machine operation, operate the machine with about 70% of the maximum
speed as “operation for total fitting” for about one month after installation. By performing
operation for total fitting, life of the machine will become longer, which will be useful to
avoid unexpected troubles.
WARNING
To prevent accidents resulting in injury or death and physical damage, the following items
must be observed strictly when operating the machine.
<Before Starting the Machine>
This machine is designed for industrial use. Use this machine for semi- or finished textile
products and similar materials. Using the machine for other purposes must be avoided.
Use the machine in the environment where only authorized persons are permitted to enter,
so that unauthorized persons will not manipulate the machine.
Only the persons who are sufficiently trained for the operation must operate the machine.
Do not have children access to vicinity of the
machine.
The rear of the machine is not a working area. If you
have to move to the rear of the machine, make sure
to turn off the main switch.
Do not stand on the machine. Using the bar switch as
a grip to support yourself is strictly prohibited.
Read this manual and thoroughly understand the
contents of operation before starting the machine.
Wear proper clothes and tidy up yourself so that you
can smoothly perform the operation.
A single operator should operate the machine in prin-
ciple. If plural operators are working together, make
sure that no one is working near the moving units of
the machine before starting the machine.
Do not damage, modify or heat the power or other
cables. Do not exert undue force to them, either. Oth-
erwise the cables will be damaged causing fire and
electric shock.
Insert the power cable plug fully. If a metallic part
touches a blade in the plug, it may cause fire and/or electric shock.

CAUTIONS ON MACHINE OPERATION
WARNING
<During the Machine Operation>
Do not use a device such as a cellular phone that
generates microwave near the control circuits of
the power supply box, the operation panel box,
etc. Microwave may cause malfunctioning of the
machine.
Do not remove the covers for the shaft and the pul-
leys when the machine is running. Do not run the
machine without the covers.
Do not have your hands or face access to movable
units during running of the machine. Especially,
the vicinities of needle, rotary hook, take-up lever, and pulley are dangerous.
Keep away control units such as the power supply box and the controller box (operation
panel box) from water and chemicals. Entry or splashing of them into control units leads
to short circuits of internal circuits, causing fire, electric shock and other troubles. If water
or other chemicals enter a control unit, shut off the power at the primary power source
and contact your local distributor.
<During Machine Adjustments>
Stop the machine before carrying out work near the needles such as threading the needle
and checking the finish of embroidery.
Shut off the power supply by turning off the power switch before manually rotating the
main shaft of the machine.
Turn off the primary power source before opening the electrical boxes. Be sure to turn off
the power switch of the machine before turning off the primary power source. If not, it may
cause electric shock.
CAUTION
When operating the machine, always observe the following items to prevent machine or prop-
erty damage.
Do not use bent needles or those that do not fit the materi-
als.
After the completion of work, shut off the power source by
turning off the switch of the power distributor panel.
Do not put things on the table.

WARNING LABELS
Important directive items
The machine has warning labels that bear instructions for safe operation. Machine operators must follow the instructions shown on
the warning labels.
Do not detach the warning labels nor make them illegible by painting, etc.
If a warning label is missed or damaged, please consult your local distributor.

Although the shape of stand differs
depending on model, applying position
is the same.

High voltage mark
There could be in danger of electric shock, burning, or death. Persons except for service personnel desig-
nated by us should not open covers. When opening covers, wait for four minutes after turning off the
power switch.

[E]
The term “Safety cover” in the label [A] and [B}
refers to all covers installed near movable units of the
machine.

MAIN FUNCTIONS
MAIN FUNCTIONS
NOISE-REDUCTION MECHANISM
Variety of noise-reduction mechanism keeps working environment com-
fortable.
POWER FAILURE MEASURE
It is possible to prevent the loss of products due to design displacement, etc.
if power is shut off during machine operation.
CLEAN-UP FUNCTION
It disposes fine stitch data automatically to prevent skip stitches and thread
breakage.
MEMORY
The machine includes 1,114,000-stitch memory as standard equipment, and
it is possible to register up to 99 designs at the maximum.
TAKE-UP LEVER GUARD
It adds stability to thread movement, and prevents entangling of thread or
coming-off of thread.
ENLARGE, REDUCE AND ROTATE DESIGN
It is possible to reduce/enlarge size of embroidery design within a range of
50 to 200% in increments of 1%. Rotation can be changed in increments of
1 degree.
AUTOMATIC REPEAT
It is possible to set up to 99 times at the maximum for X and Y directions
individually by inputting value for the number of repeats.
FDD BUILT-IN
One piece of floppy disk can register up to 111 designs•about 240,000
stitches at the maximum in case of 2DD, and up to 223 designs•about
480,000 stitches at the maximum in case of 2HD to the memory.
EDIT OF DESIGN DATA
Design can be edited (modified, inserted, deleted) in 1-stitch units.
FRAME BACK
It is possible to return the embroidery frame by stitch unit, stop code unit,
and specifying the number of stitches.
TRACE FUNCTION
The function checks if the design fits in the frame to be used before starting
embroidery.
AUTOMATIC UPPER/UNDER THREAD TRIMMER
Automatic thread trimming is performed by instruction of design data. It is
also possible to activate the machine manually as desired to trim thread.
THREAD TENSION SUITABLE FOR HIGH-SPEED OPERATION
Highly stable thread tension is realized by the adoption of middle thread
guide with tension spring and upper thread lock mechanism.
ROTARY TYPE THREAD BREAKAGE DETECTION MECHANISM
Stable detection of upper/under thread breakage is made possible even at
high-speed operation.
AUTOMATIC/MANUAL OFFSET
It is possible to make the frame move to the position automatically where it
is easy to change applique or frame. After the work, it is possible to return
the frame to start position of design. (Automatic offset)
In addition, it is possible to return the frame to the position before traveling
even if it was moved manually in process of embroidery (manual offset).
SATIN STITCH
It is possible to reduce/enlarge stitch length within a range of -1.0 to 1.0
mm.
