DANGER
To prevent any trouble caused by accidental machine start, always
shut-down the power before starting the maintenance and
adjustment work.
The XY-axis uses a very strong magnet.
•
Do not put any metallic object close to the magnet surface. Once the
magnet attracts a metallic object, this object cannot be removed due to
strong magnetic force.
•
Before starting the maintenance work, take off precision portable devices,
such as a wrist watch from your body.
•
Do not allow personnel who uses a precision medical device, such as an
artificial cardiac pacemaker, etc to carry out the maintenance work.
