xxii• As a general rule, do not use extension cords. Using an extension cord may result ina fire or electrical shock. If an extension cord must be used, however, use one ratedfor voltages of 220 - 240 V AC and over, untie the cord binding, and insert the powerplug completely into the extension cord outlet to ensure a firm connection betweenthe power cord and the extension cord.• Do not use power supplies with voltages other than those specified herein, as thismay result in a fire or electrical shock.• Always grasp the power plug when disconnecting the power cord. Pulling on thepower cord may expose or snap the core wire, or otherwise damage the power cord. Ifthe power cord is damaged, this could cause current to leak, resulting in a fire orelectrical shock.IMPORTANTLeave sufficient space around the power plug so that it can be unplugged easily. If objectsare placed around the power plug, you will be unable to unplug it in an emergency.HandlingWARNING• Do not attempt to disassemble or modify the machine.
