Cautions in Using with Safety 

Fundamental Matters of "WARNING!" and "CAUTION!" 

 

  WARNING! 

 

 

Do not use this unit in an area where there is flammable or explosive gas 

Never use this unit in an area where there is flammable or explosive gas. This unit is not explosion-
proof.    An  arc  may  be generated  when  the  power  switch  is  turned on  or  off,  and fire/explosion may 
result. (Refer to page 40 "List of Dangerous Substances".) 

 

 

Always ground this unit

 

Always ground this unit on the power equipment side in order to avoid electrical shock due to a power 
surge. 

 

 

If a problem occurs

 

If smoke or strange odor should come out of this unit for some reason, turn off the power key right away, 
and then turn off the circuit breaker and the main power.    Immediately contact a service technician for 
inspection. If this procedure is not followed, fire or electrical shock may result. Never perform repair work 
yourself, since it is dangerous and not recommended. 

 

 

Do not use the power cord if it is bundled or tangled

 

Do not use the power cord if it is bundled or tangled.    If it is used in this manner, it can overheat and 
fire may be caused. 

 

 

Do not process, bend, wring, or stretch the power cord forcibly

 

Do not process, bend, wring, or stretch the power cord forcibly.    Fire or electrical shock may result. 

 

 

Substances that can not be used

 

Never  use  explosive  substances,  flammable  substances  and  substances  that  include  explosive  or 
flammable ingredients in this unit. Explosion or fire may occur. (Refer to page 40 "List of Dangerous 
Substances"
.) 

 

  Do not disassemble or modify this unit

 

Do not disassemble or modify this unit.    Fire or electrical shock or failure may be caused. 

 

  Do not touch high-temperature parts 

The inside of the body or the door may become hot during and just after operation. It may cause burns. 

 

  CAUTION! 

 

 

During a thunder storm

 

During a thunderstorm, turn off

 

the power key immediately, then turn off the circuit breaker and the main 

power.    If this procedure is not followed, fire or electrical shock may be caused.
