Troubleshooting Guide
Maintenance
10.1 Lubrication of contra-angle handpiece
• Lubrication should be limited to the contra-angle handpiece only. Apply lubricant spray after each
use and/or before sterilization.
• When you lubricate, please aim an injection nozzle at the rear part of the contra-angle and
lubricate for 2-3 seconds. • Do not lubricate the motor of the handpiece.
10.2 Cleaning motor of the handpiece
• When the motor of the handpiece becomes dirty, wipe it off with a cotton cloth moistened with
rubbing alcohol.
10.3 Cleaning charger
• When the charger becomes dirty, wipe it off with a cotton cloth moistened with surgical spirit.
10.4 Sterilization
• Sterilize the contra-angle handpiece only. For the sterilization method we recommend autoclaving.
• Please use a brush (do not use metal brush) to brush away the dirt attached to the surface, and then
wipe it with a clean soft cloth using surgical spirit.
• Please place the contra angle handpiece into a sterilization bag and seal it.
• The temperature should not exceed 135°C (eg 121°C for 20 minutes or 132°C for 15 minutes is ideal
for autoclaving).
• Keep the contra-angle handpiece in the autoclave pouch to keep it clean until you use it.
