CAUTION • Ensure connect “Coupling and Hose” or “Handpiece and Coupling” firmly. • Do not pull the Connector Ring while the handpiece is under air pressure. It may jump the handpiece out from the connector because of the air pressure. • Do not exceed the recommended air pressure. If it exceeds the pressure, it may bur jump out from the handpiece. • Ensure clean, dry air supply. Moisture and debris in air supply may cause the motor to malfunction.

Follow the check below, before use. If any abnormalities are found, stop using the handpiece immediately and contact the authorized NSK dealer. 1) Insert the Bur. (Do not exceed maximum rotation speed for any item.) 2) Check that there is no abnormal rotation, vibration, noise and overheating. 3) If there are no immediate apparent abnormalities, continue to rotate the handpiece for about 1 minute. Then check that there is no abnormal heating on the outer surface. 4) Operate it if there are not abnormalities above. 5

4. Insertion /Removal of the Bur

CAUTION • Do not use non-standard burs. The ISO standard shank diameter is φ1.59 - φ1.60 mm. • Do not exceed the bur speed recommended by the bur manufacturer. Moreover, do not use the bur which it has lower rotation speed. • Do not use long surgical burs. Do not use burs longer than 26mm. • Do not use short shank burs. (M600LG M4, M600LG B2, M600LG QD) • Always keep the bur shank clean. Entry of hard debris into the chuck via the bur shank could cause rotation slip and also prevent the bur from being securely located in the chuck. • Fully depress the Push Button and insert the bur into the chuck until it is secure. • Test that the bur is secure by gently pulling and pushing the bur without depressing the Push Button.
