1) Screw the spray nozzle onto the spray nozzle.
2) Insert the spray nozzle into the rear part of the contra angle
head and lubricate the head for 2-3 seconds. (Fig. 12)

When the motor handpiece becomes dirty, wipe it off with a cotton cloth moistened with isopropyl alcohol.
CAUTION
• Do not lubricate the motor section of the motor handpiece.
• To clean the motor handpiece, do not use any solvent such as benzine and, thinner.
• Before mounting the lubricated contra angle head to the motor handpiece, wipe off extra oil. Stand on its end or
lean it in the proper position for gravity draining. Mount it after excess oil has been drained.
• Hold the contra angle head securely to prevent it from flying off by the pressure of the spray.
• Supply lubricant until it comes out of the handpiece head (for approx. 2 seconds).
• Do not use a spray can upside down. In such a case, only spray gas comes out and oil is not sprayed.
