§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.
