KaVo Maintenance Kit

As a medical device manufacturer, we are obliged to stipulate maintenance activities, technical safety inspections and integrated unit tests. This approach serves two purposes: it ensures functional safety and prevents damage, health hazards and legal risks. Regular maintenance also prevents expensive downtimes and helps you to preserve the value of your unit.

KaVo recommends the annual maintenance service for your treatment units to ensure continuous operational readiness, safety and value preservation of the KaVo product. 

The annual maintenance service also helps to comply with the specifications, standards and laws in your country. Please observe the statutory provisions in your country.
