CAUTION · Be sure to hold the handpiece firmly to prevent the handpiece from slipping out by the spray pressure when lubricating. · Keep the NSK PANA SPRAY Plus / PANA SPRAY can upright. · Use of lubricants other than NSK’s PANA SPRAY Plus / PANA SPRAY can cause excessive heat generation and possible handpiece damage.

CAUTION of Sterilization

· Always place the handpiece in the center or upper shelf of the chamber, as the local temperature at the bottom of chamber could rise beyond the set value. · Do not autoclave the handpiece even when it is bagged, together with other instruments, from which chemicals are not sufficiently cleaned. This is to avoid discoloration and/or damage the plating of the handpiece/motor. · Do not heat or cool the handpiece quickly. Rapid change in temperature could break the glass rod and give abnormal strain to other metals. (Optic handpiece/motor) · We do not recommend you to sterilize on plasma sterilization or EOG sterilization.

6. Storage
