CHAPTER 1 IMPORTANT WARNING ITEMS FOR SAFE OPERATION

1. 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). If the floor is
supported by steel frames, place the machine stand on the
steel beams as long as possible.
Prevent the operation noise in the environment.
To improve 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 insulating 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 discol-
ored or deformed. Put curtains or shades to the site to pre-
vent the machine from direct sunlight.
Provide enough space for maintenance.
For the maintenance purpose, provide at least 50 cm clear-
ance 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 conden-
sation
Ambient temperature: 5 to 40°C (during operation), -10 to
60°C (during storage)

2. 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 prod-
ucts 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 more than one operator are working together, make
sure that no one is working near the moving parts 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.
