§1 INTRODUCTION
• This service manual provides information for after-sales service for the NIDEK multifunction
edger, model: ME-1000.
• Technical contents for producing eyeglass lenses are not contained in this manual.
• For proper after-sales service, it is necessary to understand this manual thoroughly before
servicing.
• Refer to the NIDEK multifunction edger, model: ME-1000 Operator’s Manual and Parts List.
• Specifications are subject to change without notice for improvement. As for important changes,
refer to the Technical Bulletins (T.B.).
• In case the device cannot be repaired according to the procedures described in this manual,
please tell us the serial number of the device and details of the symptom or symptoms.

§2 SAFETY PRECAUTIONS
2.1 General Precautions
• Only the service persons who are accustomed to using tools, and have a deep knowledge of
this instrument are allowed to repair the instrument.
• Proceed right work in accordance with the procedure.
If not, accidents or failure of the instrument may result.
• When the instrument is moved, it should be carried by two or more persons. Otherwise, you
may have a backache or fall down.
• When performing maintenance works, turn off the power switch, and disconnect the power
cord from the wall outlet unless necessary.
• Never wipe the covers, etc. using an organic solvent such as a paint thinner.
The surface may be ruined, and as a result, the appearance of the instrument will be impaired.
<Maintenance precautions>
• In case of instrument malfunction, turn the power switch off after checking the symptom.
• Never drop parts or screws inside the instrument, nor bump it against the surrounding objects.
• Have storage cases ready to ensure the loss of the removed screws or parts.
• In screwing or unscrewing, use a proper tool for the screw.
• After loosening the screws fixed by a threadlocking adhesive, and tightening them again, be
sure to apply the threadlocking adhesive to them.
• After replacing parts, make sure that they are fixed securely before turning on the power.
• If you observe strange odors or smoke being emitted from the instrument, immediately turn
off the instrument and locate the causes after disconnecting the power cord from the wall-
outlet.
If the instrument is continuously powered under such abnormal conditions, a fire, electric
shock or total loss of the instrument may result.
• Referring to “8.1 Wiring Diagram” and “8.2 Connector Cables”, check cables for the following:
1. Connectors are connected securely.
2. No contact failure occurs after re-connection of connectors.
3. No failure in soldering
Do not pull the cables strongly. It may cause a breaking of wire.

LLE11ARDA001A/E
• Never work with wet hands.
It may result in an electric shock or instrument malfunction.
• Avoid spraying water into the instrument.
• Do not exert excessive force to the stylus of the tracing unit.
It may cause a deformation of the stylus or instrument malfunction.
• Before grinding, select and specify a proper lens material to be ground.
In case of improper selection of the lens material, the lens to be ground may break or grinding
wheels may become damaged.
• Never fail to shut the soundproof cover while the wheels are turning.
Otherwise, grinding splash may get in your eye and hurt it.
• While rotating wheels and V belt, never bring your hand or face near to them.
It may hurt your hand and face.
• Replacement of the wheel must be done after cleaning the wheel and the wheel housing,
wearing gloves to protect your hand from ground powder.
• After grinding a glass lens, chamfer each ground edge of the front and rear side of the lens.
After grinding, glass lenses may have fine burrs. They may hurt your skin.
• Do not use a calibration jig for other usage described in this manual.
