and Charging Base
• Clean all the surfaces with CaviWipes™ or a cloth lightly
moistened with other intermediate level disinfectant per
manufacturer instructions.
• Use a cotton swab and a small, soft brush moistened with
CaviCide™ or other intermediate level disinfectant to
remove any soil that may have accumulated in crevices
(e.g. between Button and the body of the device, between
the LCD display and the body of the device). Wipe the device
with additional CaviWipes™ or cloths lightly moistened
with intermediate level disinfectant until no visible soil is
detected on the cloth. Visually inspect the device/charging
base to assure cleanliness. If any contamination is visible,
repeat the cleaning steps. Use one more CaviWipes™ or a
cloth moistened with disinfectant to ensure that no residual
contaminants are left on the device.

Cleaning, Lubrication and Sterilization of the
Contra Angle
The contra angle must be lubricated and sterilized after cleaning.
Frequent use and reprocessing may cause wear to the contra
angle chuck. If symptoms such as wear or discoloration appears,
the contra angle should be replaced.
Cleaning:
1. Thoroughly clean the contra angle immediately after each
patient use, following the cleaning steps to prevent drying
of soil and contaminants.
2. The contra angle should be inspected prior to cleaning
for the appearance of defects such as deformations or
corrosion, which are indicators that the instruments are not
in conditions to be re-used and must be discarded.
3. Immerse the contaminated contra angle in tap water for
5 minutes.
4. Using isopropyl alcohol containing tissue (ex. Cavi Wipes),
wipe all surfaces twice for 1 minute.
5. Rinse with tap water for 30 seconds.
6. Wipe off the water with a soft cotton cloth.
7. Dry at room temperature for at least 30 minutes.
8. If the device is determined not to be visually clean at the
end of the cleaning step, the user should either repeat the
relevant previous cleaning steps.
Lubrication and Packaging :
Lubricate the contra angle at least once a day after using the
device or before sterilization.
1. Insert the contra angle into the nozzle of the handpiece oil spray.
2. Apply the oil spray for at least 3 seconds to drain the oil from
the contra angle.
3. Remove the nozzle from the contra angle and wipe off
any oil on the outside of the contra angle with a gauze
moistened with ethanol.
4. Stand the contra angle on the gauze to allow any residual oil
inside to drain.
5. Place the lubricated contra angle in a sterilization pouch
which is FDA-cleared and/or ISO 11607/DIN 58953-7
compliant.
Sterilization:
1. Place the contra angle packed in a pouch into an autoclave
(pre-vacuum type) and heat it under the following conditions.
2. Recommended sterilization parameters:
Cycle
Temperature (°C)
Exposure time (min)
Drying time (min)
