Maintenance and Check
CAUTION
• When disconnecting the power cord from an outlet, do not yank the power cord.
Always pull it by the plug.
This can damage the metal core of the cord and may result in electric shock, short cir-
cuit or fire.
• 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.
Fire may occur.
• Verify that the following specified environmental conditions for transport and storage
(packed condition) are met.
Environmental conditions
Temperature: -15 to 65ºC (5 to 149ºF)
Humidity: 20 to 85% (non-condensing)
A place with low dust
A place not exposed to direct sunlight
• 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.
CAUTION
• Be sure to perform inspections before and after use. It is recommended to have
periodic performance checks every two years.
Periodic checks must be performed by qualified personnel. Contact NIDEK or your
authorized distributor.
The blocking motor requires replacement every two years use or after eight hundred
thousand rotations.
• When performing maintenance work, secure a sufficient maintenance space (see
page V).
Maintenance work in an insufficient space may result in injury.
• Use the specified fuses to replace the old ones.
If not, a fire may occur.
