1 FOR SAFE USE
1.1 Read before Use
1.2 Signal Words for Safety
BEFORE USE, READ THIS MANUAL.
The cautions for safety and operating procedures must be thoroughly understood before
using the instrument.
Keep this manual handy for reference.
In this manual, signal words are used to designate the degree or level of safety alert-
ing. The definitions are as follows.
WARNING
Indicates a potentially hazardous situation which, if not avoided, might result in death or seri-
ous injury.

FOR SAFE USE: Usage Precautions
1.3 Usage Precautions
Before use
WARNING
• Use a hand cart when moving the instrument. At least
two persons are necessary to lift the instrument.
Failure due to dropping of the instrument, backache,
or stumbling may occur.
• Be sure to lift the instrument by holding it at the points
, , , and at the bottom of both sides
(see the figure to the right). Do not lift the instrument
by its cover.
Failure to do so may cause the instrument to fall
resulting in injury or malfunction.
• Be careful not to get fingers caught when setting the
instrument down.
Fingers may get caught between the table and instrument resulting in injury.
• Set the instrument on a table whose area is larger (50 mm or more) than the outer dimensions of the
instrument as shown below. A table height of 650 to 700 mm is recommended to allow space for the
pump tank to be installed under the table.
Additionally, the table must be sturdy enough to bear the weight of the instrument (33 kg) and be
provided with adjusters on its legs to allow it to be level and stable.
Failure to do so could cause the instrument to fall in the event of impact or accidents.
An opening must be made in the table to pass the pipe through.
• Install the instrument in a stable and level place where vibration or shock does not occur.
Tilting or vibration can cause the instrument to fall or prevent normal lens processing.

FOR SAFE USE: Usage Precautions
CAUTION
• Do not use the instrument for any purposes other than the intended purpose.
NIDEK is not responsible for accidents or malfunctions caused by misuse.
For the intended purpose of the instrument,  “2.1 Outline of the Instrument” (page 12).
• Only personnel authorized by NIDEK or a NIDEK distributor are allowed to install the instrument.
• Install the instrument in an environment that meets the following conditions.
The following conditions must be maintained during use.
•Use conditions
Temperature: 5 to 40°C (41 to 104°F)
Humidity: 30 to 80% (5 to 31°C [41 to 87.8°F])
The minimum acceptable relative humidity is 30%. The maximum acceptable relative humidity is 80% for
temperatures up to 31°C (87.8°F) which decreases linearly to 50% at 40°C (104°F).
Altitude: Up to 2,000 m
Installation location: Interior (with low dust and free from smoke, vibration, and impact)
• Install the instrument in a location with an adequate operating area in front of the instrument as
shown in “Maintenance” (page 5).
• Be sure to wear protective gloves when using a utility knife during unpacking.
Contact by bare hands with a utility knife or sharp edge of cardboard may result in injury.
• Install the instrument on a table with a height and depth that allows comfortable operation.
Continued use in an awkward posture may result in backache.
• Do not block the cooling fan on the rear of the instrument.
Should the fan be blocked, rise in temperature inside the instrument may occur resulting in fire.
• Avoid installing the instrument where it is exposed to caustic material such as corrosive gas, acid, or
salt.
Corrosion or malfunction may occur.
• Do not use the power cord other than those supplied. Also do not connect the supplied cord to any
other instrument.
Malfunction or fire may result.
• Do not overload the electrical outlet.
A multi-outlet supplying power to too many instruments may become overheated and cause fire.
• Install the instrument in area where the outlet that the power plug is inserted into is easily accessible
during use. In addition, ensure that the power cord can be disconnected without the use of any tool.
Failure to do so may interfere with disconnecting of the power from the input power source in case of
abnormality.
• Be sure to use a wall outlet which meets the power specification requirements.
If the line voltage is too high or too low, the instrument may not perform properly. Malfunction or fire may
result.
• Completely insert the power plug into a grounded outlet as far as the prongs will go.
Electric shock or fire may occur in the event of malfunction or power leakage
• Do not place heavy objects on the power cord.
A damaged power cord may cause fire or electric shock.
• Check the connection of the feedwater and drain hoses before activating the instrument.
Electric shock due to water leakage or injury caused by wet slippery floor may result.

FOR SAFE USE: Usage Precautions
During use
WARNING
• Only personnel authorized by NIDEK or a NIDEK distributor are allowed to remove the cover fasten-
ing screws and covers, disassemble, or touch the interior of the instrument.
Electric shock, injury, or malfunction may result.
• Never touch the wheel while it is rotating.
Injury may result.
• Never open the processing chamber cover during lens processing.
Spray containing processing waste may cause eye damage.
• Be sure to use the instrument only to process spectacle lenses.
If any other materials are processed, injury may occur.
• Be sure to visually check that wheels are not chipped or cracked before processing. If the wheels
are chipped or cracked, immediately stop the instrument and contact NIDEK or your authorized dis-
tributor.
If chipped or cracked wheels are used, they may break or shatter resulting in injury.
• Do not inhale vapor and particles produced during lens processing. Wear a protective mask,
glasses, and such as necessary.
Vapor or particles may be toxic depending on the materials.
CAUTION
• In the event of smoke or strange odors, immediately turn off the instrument and disconnect the
power plug from the wall outlet. Once it is confirmed 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.
• Immediately replace the power cord if the internal wires are exposed, power is intermittent when the
