It is strongly advised that the following safety measures must be observed to ensure the safe
operation of the machine:
•Read precaution instructions described in this manual before connecting the power plug
into the outlet.
•Always use a power supply with rated voltage. Never connect the machine power input with
an AC power supply exceeding the rated voltage. To avoid any potential electrical shock,
ensure that the protective ground wire is connected to the main grounding provision.
Using the machine outside of the rated voltage may result in machine failure or danger such as
electric shock.
•Prepare a dedicated power source.
A power supply that generates voltage variation may cause a malfunction.
•Do not stand on the power cable, and do not place anything heavy on the cable.
Doing so may damage the cable, resulting in accident or trouble.
•Disconnect power supply before servicing.
To ensure your personal safety, disconnect the power supply before servicing.
•Take precaution against residual electrical charge hazard.
Capacitors inside the machine may still hold an electrical charge even after power is disconnected.
•Do not remove covers or enclosures.
To avoid personal injury and shock, do not open or remove any covers or enclosures of the machine
unless specified in the manual.
•Do not perform unspecified maintenance.
For your personal safety, do not perform any maintenance procedures which are not specified in the
manual.
