1. Safety Information

• Be sure to disconnect the power cord from the wall outlet at least once a year and check for the

following:

• The power cord's inner wires are exposed, broken, etc.

• The power cord's coating has a crack or dent.

• When bending the power cord, the power turns off and on.

• Part of the power cord becomes hot.

• The power cord is damaged.

• If any of the above conditions exist, do not use the power cord and consult your dealer or

service representative. Use of the power cord could result in fire or electric shock.

• Do not use the connection cable if it is deformed, cracked, or damaged. Doing so could result

in fire or electric shock. If the connection cable is deformed, cracked, or damaged, contact

your service representative to request a replacement cable.

• When using an extension cord or power strip, only connect equipment whose total power

consumption is within the power rating for the extension cord or power strip. If the power rating

is exceeded, it may cause heat buildup and result in fire.

• Push the power plug all the way into the power outlet. Do not use a power outlet with a loose

connection. Doing so may result in heat buildup. Plug the power cord in the correct direction

into the base. If they are not plugged in correctly, it could result in smoke, fire, or electric shock.

• If this machine is not going to be used for several days or longer at a time, disconnect its power

cord from the wall outlet.

• When disconnecting the power cord from the wall outlet, always pull the plug, not the cord.

Pulling the cord can damage the power cord. Use of damaged power cords could result in fire

or electric shock.

• Be sure to disconnect the plug from the wall outlet and clean the prongs and the area around

the prongs at least once a year. Allowing dust to build up on the plug constitutes a fire hazard.

• When performing maintenance on the machine, always disconnect the power cord from the

wall outlet.

• Do not place the power cord and connection cable in a way that might cause someone to trip

and fall. The machine might fall over and cause an injury.
