Warnings
The use of strong detergent and disinfectant (alkaline pH>9 or acid pH <5) will reduce the life span of products. And in
such cases, the manufacturer takes no responsibility.
Do not clean the handpiece with ultrasound cleaning machine.
This device shall not be exposed to high temperature above 138C.
Processing limit
The products have been designed for a large number of sterilization cycles. The materials used in manufacture were
selected accordingly. However with every renewed preparation for use, thermal and chemical stresses will result in
ageing of the products. The maximum number of sterilizations for handpiece is 600 times. For tips, it is 300 times. And
for wrench, it is 1000 times.
4.1 Initial processing
4.1.1 Processing principles
It is only possible to carry out effective sterilization after the completion of effective cleaning and disinfection. Please
ensure that, as part of your responsibility for the sterility of products during use, only sufficiently validated equipment
and product-specific procedures are used for cleaning/ disinfection and sterilization, and that the validated parameters
are adhered to during every cycle.
Please also observe the applicable legal requirements in your country as well as the hygiene regulations of the hospi-
tal or clinic,especially with regard to the additional requirements for the inactivation of prions.
4.1.2 Post-operative treatment
The post-operative treatment must be carried out immediately, no later than 30 minutes after the completion of the
operation. The steps are as follows:
1. Let the Ultrasonic Scaler works for 20-30 seconds at maximum water volume to flush the handpiece and tip;
2. Remove the handpiece from the Ultrsonic Scaler, and rinse away the dirt on the surface of product with pure water
(or distilled water/deionized water);
3. Dry the product with a clean, soft cloth and place it in a clean tray.
