• Does my transmission instrument need maintenance?

  
  Whether straight and contra-angle handpieces, couplings or turbine handpieces – in daily operation it can happen again and again that transmission instruments suddenly fail. For people who want to be on the safe side and value the long service life of the products, we would like to point out the recommended annual maintenance. Regardless of this, there are various signs that indicate a need for maintenance or repair. Here are some examples of how you can determine the maintenance need for your transmission instruments:

  •High temperatures
  •Strong vibrations
  •Increased volume
  •Lower power/speed
  •Reduced bur holding force
  •Decreasing light intensity/light fluctuations
  •Impairment of spray intensity/spray fluctuations
  •Coolant failure or leakage

  If you notice one or more of the above-mentioned operating malfunctions, contact an authorised .

  

• Safety technical checks for medical devices

  
  To ensure safety of users, patients and third parties, medical electrical devices must be checked regularly. For this reason, the Medical Devices Act provides safety checks. During the check, it is determined whether a device is functional, electrically safe and in proper condition at the time of inspection. The safety check must be carried out every three years or according to the manufacturer's instructions. For W&H devices such as Implantmed or Piezomed, the safety check is mandatory every three years. National regulations can include exceptions for shorter inspection periods. In Germany, for example, the safety check has to be carried out every two years.

  The safety check may only be carried out by qualified companies and institutions. These companies confirm the proper functioning of the devices and thus ensure the safety of patients, users and third parties.

  The safety check is subject to all W&H stand-alone devices such as Implantmed, Elcomed, Piezomed, Pyon, Tigon/Tigon+ or Proxeo Ultra.

• What are maintenance kits? And why are they so smart?

  
  Every product, whether in the private or professional field, is exposed to a certain amount of wear over time. This wear could only be visually disturbing or lead to a real defect. Maintenance kits can help, since they contain exactly the spare parts that need to be replaced – no more and no less!

  Maintenance kits are designed either for end users or for service partners and are tailored to a defined product. A popular example is our maintenance kits for W&H sterilizers, which are normally used after 800 or 4,000 sterilization cycles for the recommended service.

  •Service after 800 cycles: Do it yourself! The spare parts included in the maintenance kit can be replaced by the end user. The costs can be calculated exactly. The original spare parts contribute to the long service life of the sterilizer.
  •Service after 4,000 cycles: The service after 4,000 cycles can only be carried out by an authorised service technician or a specialist workshop. The device must be opened and the parts included in the maintenance kit must be replaced. The costs for this can also be calculated exactly.

  Maintenance kits thus offer absolute cost transparency. The advantage over purchasing individual spare parts is obvious. For information on all available maintenance kits, please contact your

• Perfect cleaning – without tools

  
  Surgical interventions are a great challenge. In order to meet the high hygiene requirements, the W&H surgical straight and contra-angle handpieces of the S and WS series can be disassembled quickly and easily. Total simple – without tools. This not only facilitates thorough cleaning, but also extends the service life of your instruments. The surgical straight and contra-angle handpieces can then be reassembled just as quickly and easily.

  How to properly disassemble and reassemble our surgical contra-angle handpiece WS-75 is shown in this "video".
