4.11 Periodical Check
It is recommended to perform an inspection every two years in order to use the instrument for a
long time under normal conditions. In the periodical inspection, a performance check of the
whole system and replacement of maintenance parts are done.
If inspection is required, contact NIDEK or your authorized distributor.
* Replace the wheel every two years or after the processing of five thousand lenses. Contact
NIDEK or your authorized distributor. However, the lens number is referred only as a guide,
so replacement at an earlier period may be needed under such conditions that hard lenses have
been processed successively or numerous high-power minus lenses have been processed.
Be careful not to dress or process glass lenses with the wheel for plastic lenses. If the wheel
has been damaged because of such carelessness, it will extremely shorten the lifetime of the
wheel.
