§ 2 SAFETY PRECAUTIONS
<General precautions>
• Maintenace must be performed by NIDEK service persons or other qualified personnel.
• Perform all maintenance according to the procedures described in this manual.
Failure to do so may cause unexpected accident or malfunction.
• When moving the system, use two or more persons. You may hurt your back or may fall
down if you carry it alone.
• When performing maintenance, turn off the power switch and disconnect the power cord
from the wall outlet unless the power needs to be on.
• Never wipe the covers using an organic solvent such as a paint thinner. Doing so may ruin
the surface and damage the appearance of the system.
<Maintenance precautions>
• In case of system malfunction, check the symptom and turn off the power .
• Do not drop parts or screws inside the system, nor bump it against surrounding objects.
• Prepare storage cases so as not to lose the removed parts or screws.
• Tighten or loosen screws with proper tools.
• After loosening the screws fixed by a threadlocking adhesive, be sure to reapply the
threadlocking adhesive to the screws when retightening them.
• After replacing parts, confirm that they are fixed in their original positions securely before
turning on the power.
• Should you observe smoke or strange odors being issued from the system, immediately turn
off the power switch, disconnect the power cord from the outlet, and investigate the cause.
If the system is powered in abnormal conditions, fire, electric shock, or total loss of the
system may result.
• See Wiring Diagram and Connecting Cable to check cable breaks as described in
“TROUBLESHOOTING”. In addition, check cables for the following:
1. Connectors are connected and crimped securely.
2. No contact failure occurs after re-connection of connectors.
3. Cables are soldered properly.
Do not yank the cables with excessive force. Doing so could cause cable breakage.
• Do not perform servicing with wet hands. Doing so could cause electric shock or malfunction.
• Prevent water seepage into the system.
• Do not apply excessive force to the stylus of the tracing unit. Doing so could cause deformation
or malfunction of the stylus.
• Make a lens material selection correctly according to the lens to be processed. If an improper
material is selected, the lens may break or the lifetime of processing wheels may be shortened
substantially.
• Never open the processing chamber door while the wheel is rotating. Spray containing
processing waste may come into your eyes.
• Keep hands and face away from the rotating wheel.
• Replace the wheel with gloves on after cleaning the wheel and inside of the processing
chamber. Bare hands can be hurt by glass-processing waste.
• Safety bevel the front and rear surfaces of glass lenses after processing. Subtle burrs may
damage your skin.
• Never use the adjustment jigs for purposes other than those intended.
