Warning and Caution
Warning
1. Never use the machine in atmosphere containing ignitable and explosive
gases.
Never use the machine in atmosphere containing ignitable and explosive gases. The ma-
chine is not of explosion-proof construction. Turning on and off the switches and operating
the machine will produce sparks, which may become a cause of a fire or explosion. (See
13. List of Hazardous Substances on page 26.)
2. Never use explosive and flammable substances.
Never use explosive and flammable substances and substances containing such substanc-
es. The machine is not equipped with safety features against such substances. They are
a cause of explosion and fire.
3. Never use the machine in abnormal conditions.
If you notice smoke, offensive odor or other problems, immediately turn off the circuit breaker
of the machine and also turn off the power of the distribution panel on the building side.
They are a cause of a fire and electric shock.
4. Never disassemble or modify the machine.
The machine must not be disassembled or modified by the user. Unauthorized disas-
sembly and modification are a cause of failure, fire, electric shock and other accidents.
5. Handling of the power cords.
Do not use bundled power cords. Such a way of use may cause the cords to overheat to
cause a fire.
Do not machine power cords or bend, twist or pull them by undue force. Hazard of a fire
and electric shock.
Do not damage power cords by for example placing them under a desk or chair or clamping
them by devices. Hazard of a fire and electric shock.
Do not bring power cords near heating devices such as a heater. The coating of the cords
will be burnt to cause a fire or electric shock.
If a power cord is damaged (core wires exposed or broken), immediately turn off the power
of the machine and also turn off the source power supply. Then request the dealer for re-
placement of the cord. If such damaged cords are used, a fire or electric shock may result.
6. Be sure to use the specified reaction gas.
Be sure to use the specified processing gas (argon gas, oxygen optional). If other gas is
used, the actual flow rate becomes different from the indicated flow rate. Also other prob-
lems such as damage to products and insufficient cleaning may happen.
