During Use
WARNING
• Never touch the wheel when it is rotating.
It may result in injury.
• Never open the processing chamber door during lens processing.
Spray containing processing waste may cause eye damage.
• Be sure to use this instrument only to process lenses for glasses.
The instrument can not be substituted for a grinder. If any other materials are pro-
cessed, wheels may break and shatter resulting in injury. In addition, the damaged
wheels can not perform normal processing.
Never process combustible materials such as magnesium. If they are processed, explo-
sion or fire may occur.
• Be sure to check visually that wheels may not be chipped or cracked before
processing. If the wheels are chipped or cracked, immediately stop the instrument
and contact NIDEK or your authorized distributor.
If chipped or cracked wheels are used, they may break or shatter resulting in injury.
• Do not inhale vapor and particles produced during lens dressing. Wear a protective
mask, protective glasses and such as necessary.
There is a possibility that the vapor or particles is harmful depending on the materials.
CAUTION
• Immediately replace the power cord if the internal wires are exposed, the table turns
on or off when the power cord is moved, or the cord and/or plug are too hot to hold.
This may result in electric shock or fire.
In the event of malfunction, disconnect the power cord from the wall outlet. Never touch
the inside of the instrument and contact NIDEK or your authorized distributor.
• In the event of smoke or strange odors, immediately and disconnect the power plug
from the wall outlet. After you are sure that the smoke has stopped, contact NIDEK or
your authorized distributor.
Usage of the instrument under such abnormal conditions may cause fire or electric
shock. In case of fire, use a dry chemical (ABC) extinguisher to extinguish the fire.
• Be sure to confirm that wash water (for the inside wall of the processing chamber)
and cooling water (for the wheels) flow properly.
If the water does not flow, lenses are not processed properly and the instrument may be
damaged.
For confirmation procedures, see “2.24.1 Check before use” (page 115).
• Be sure to make the correct material selection for the lens material being processed.
In an improper material is selected, the lens may break or the lifetime of processing
wheels may be reduced substantially.
• Safety bevel the front and rear surfaces of glass lenses after processing.
Subtle burrs may damage one’s skin.
• Be careful not to get fingers caught when chucking (fixing) a lens.

V
:
After Use
CAUTION
• The processing chamber door automatically opens and closes. Be sure to keep face
or hands clear. Be careful not to catch figers with the door to being closed.
• Do not apply too much pressure on the stylus of the tracing unit.
The stylus is easy to bend or break.
• Pliable cups are consumables. Replace the pliable cup with a new one when it becomes
hard to remove the double-coated adhesive tape from the cup. (Guide of replacement:
every 1000 of lens processing)
• It is recommended to rinse lenses processed by the lens edger with water before wiping
them with a cloth or such.
Fine processing waste flying in the processing chamber of the lens edger may become adhered to
the lenses. Rinsing them in water prevents their surfaces from being damaged.
CAUTION
• Clean the processing unit after the last use of the day.
If the unit is left for some days after being used, the processing waste becomes settled
and hard to remove.
• When the instrument is not in use, turn it off and close the tracing unit lid and
processing chamber door.
If dust will accumulate, it may affect the measurement accuracy or result in malfunction.
• Occasionally clean the prongs of the power plug with a dry cloth.
If dust settles between the prongs, the dust will collect moisture, and short circuit or fire
may occur.
• If the instrument will not be used for a long time, disconnect the power cord from the
wall outlet.
If dust settles between the prongs, the dust will correct moisture, and short circuit or fire
may occur.
• Do not use organic solvents such as paint thinner to clean the exterior of the
instrument.
This could damage the surface. Fire may occur.
• Do not store the instrument in an area that is exposed to rain, water or contains
poisonous gas or where any liquids are stored.
• Verify that the following specified environmental conditions for transport and storage
(packed condition) are met.
Environmental conditions •Temperature: –25 to 70°C (–13 to 158 °F)
•Humidity: 10 to 95% (non-condensing)
• To transport the instrument, use the special packing materials to protect from shock
and impact.
Excessive vibration or impact to the instrument may cause malfunction.

VI
:
Maintenance and Check
CAUTION
• Be sure to perform check before and after use. It is recommended to have periodic
checks every two years.
Periodic checks must be performed by qualified personnel. Contact NIDEK or your
authorized distributor.
Wheels must be also replaced by qualified personnel. Do not replace the parts other
than fuses and the stocking filter nor disassemble the instrument. Failure to do so could
cause malfunction.
• Only qualified personnel can repair the instrument.
NIDEK will not be responsible for accidents caused by improper servicing.
• When performing maintenance work, secure a sufficient maintenance space (see see
page VII).
Maintenance work in an insufficient space may result in injury.
• Use a suitable dressing stick for wheel dressing.
It may damage to wheels, which prevents normal lens processing.
• Never dress the roughing wheel for plastic lenses.
It may damage to the wheel.
• When the dressing stick is worn to the length of 4 cm, replace it with a new one.
As it is hard to hold the shortened dressing stick, your hand may contact with a wheel.
• Wear protective glasses for wheel dressing.
Spray containing processing waste may cause eye damage.
• In dressing mode, the wheels are rotating with the processing chamber door open.
Work with special care in dressing.
• Use the specified stocking filter only for replacement.
If not, the filter or water supply pipe may become clogged with processing waste.
• The stocking filter is disposable. Do not reuse it.
A filter which has a rip or run in it does not function as a filter, and therefore, the water
supply pipe may be clogged.
• Use the specified fuses to replace the old ones.
Using fuses other than specified may result in fire.
