7. Cleaning
(1) Lubricating Contra Angle Head
- Lubricate the contra angle head only.
1. Lubricate it before each autoclaving or once a day if
you do not autoclave. Screw the F type spray nozzle
onto the spray nozzle by approx. 10 turns.
2. Insert the F type spray nozzle into the rear part of the
contra angle head and lubricate the head for 2-3 sec-
onds. If the contra angle head does not push into
nozzle enough, oil may not go around into the hand-
piece and it may flows backward.
(2) Cleaning Motor Handpiece
When the motor handpiece becomes dirty, wipe it off with a cotton cloth moistened with rubbing alco-
hol.
(3) Cleaning Charger
When the charger becomes dirty, wipe it off with a cotton cloth moistened with surgical solution.
CAUTION
- Do not lubricate the motor handpiece.
- Before mounting the lubricated contra angle head to the motor handpiece, wipe off excess oil. Stand it
on its end or lean it in the proper position for gravity draining. Mount it after excess oil has been com-
pletely drained.
- Hold the contra angle head securely to prevent it from flying off by the pressure of the spray.
- Hold the spray can upright.
- When cleaning the motor handpiece, do not use any solvent such as benzene and, thinner.
8. Sterilization
Sterilize the contra angle head only.
For the sterilization method, we recommend the autoclaving. Sterilization is required first time you use and
after each patient as noted below.
Autoclaving
1. Brush the dirt off the surface of the contra angle head, and wipe it off with a cotton cloth moistened with
surgical spirit. Do not use a metal brush.
2. Lubricate the head (Refer to the "7 (1) Lubricating Contra Angle Head. " )
3. Insert the head into an autoclave pouch and seal it.
4. Sterilization according to the current regulations at maximum 135°C (275°F).
5. Keep the handpiece in the autoclave pouch to keep it clean until you use it.
CAUTION
- Do not heat sterilize the motor handpiece.
- Do not wipe with, or clean or immerse in, high acid water or sterilizing solutions.
