FAQ

Straight & Contra-angle Handpieces

• Handpieces (1)
  • Should I call the service station before sending equipment for repair?
    If you are not sure what the cause of the problem is, it is better to call the service station and talk to a technician. Together with the technician it can be determined what needs to be sent in and sometimes it is possible to even solve the problem right away.

Surgical Devices

• Amadeo (16)
  • Which coolant hoses can I use with the Amadeo?
    Information on coolant hoses can be found in the Instructions for use. A length of 3.5 m is specified for the motor cable, which means that the coolant hose needs to be 3.8 m long. Sterile wrapped disposable suction hoses are included in the scope of supply; these are also available as add-on parts.
  • According to the factory settings and the approved intended use, the Amadeo can be used in five surgical applications. Is it possible to only have one/my application on the display, without having the others suggested?
    W&H recommends deleting those programs that are not used in the surgical procedure in question (e.g. ENT application -> Insertion of a hearing implant: Deletion of program sequences for ribs/thorax, orthopaedics, spine and CMF).
  • Is it possible to create an individual program sequence that differs from the factory settings?
    A further six individual programs can be created in addition to the five specified areas of application in the factory settings. The individual steps can be selected from an existing library and assigned to the new program.
  • Why are there two different screw programs in the factory settings for ‘Ribs and Thorax’ (15 rpm/30 Ncm and 150 rpm/70 Ncm)?
    The screw programs were specially designed for the RibLoc System produced by Acute Innovations and are tailored specifically to this application. The two programs differ in terms of the speed and torque; there is a slow and a fast screw-in program already available as a factory setting. In both programs, the parameters can be adjusted on the display and thus can be adapted (including for other osteosynthesis systems).
  • Which service organizations can I contact?
    The service organizations are shown on the homepage and are the same as those for the W&H dental products.
  • Can other brands of tubing be used?
    This is not recommended due to different technical data (materials etc.) as the use of different hoses has a direct impact on the specified and validated coolant volume of 90 ml/min.
  • Does my W&H unit need to be serviced.
    Regular servicing of function and safety including the accessories is necessary and should be carried out at least once every three years, unless shorter intervals are prescribed by law. Detailed information can be found in the user manual at chapter "Servicing".
  • Should I call the service station before sending equipment for repair?
    If you are not sure what the cause of the problem is, it is better to call the service station and talk to a technician. Together with the technician it can be determined what needs to be sent in and sometimes it is possible to even solve the problem right away.
  • Which coolant hoses can I use with the Amadeo?
    Information on coolant hoses (correlation of tubing) can be found in the Instructions for use. A length of 3.5 m is specified for the motor cable, which means that the coolant hose needs to be 3.8 m long. Sterile wrapped disposable suction hoses are included in the scope of supply; these are also available as add-on parts.
  • Does the motor need to be greased?
    No, the Amadeo motor does not need greasing. The motor bearings require no maintenance. Any additional greasing would reduce the service life of the bearings.
  • Can handpieces from another manufacturer be used on a W&H surgical motor (Amadeo)?
    The programs are tailored to the W&H straight and contra-angle handpieces; straight and contra-angle handpieces from other manufacturers do not have the same degree of efficiency level accuracy.
  • How does it work to wirelessly control the Amadeo?
    W&H introduces a new concept in surgery. Via dongles (receiver), which can be connected to the unit by the doctor, the wireless foot control S-NW communicates with the surgical units of W&H.
  • What do the abbreviations ENT and CMF stand for in the pre-set programs?
    The ENT program stands for use in Ear/Nose/Throat surgery; CMF stands for Crani/Maxillofacial.
  • The Amadeo and the Implantmed Plus are both suitable for use in CMF surgery. Can the dental motor of the Implantmed (EM-19) also be used in the Amadeo or vice versa?
    No, the two motors are not compatible. While the motor of one can technically be plugged into the other, the Implantmed motor will not be recognized by the software on the Amadeo (and vice versa).
  • Is there also a motor with light contacts available for Amadeo as a basis for LED lighting?
    No, the motor with the gold contacts was not included in the medical portfolio due to the efficient lighting in operating theatres. Only the WS-75 contra-angle handpiece is also available in the LG version; depending on the speed, it can be used to generate generator-induced light in the contra-angle head.
  • Can wired or wireless foot controls from an Implantmed also be used with the Amadeo?
    Yes, the foot controls (S-N2 and S-NW) are suitable for and compatible with both units.

  • No cycles are stored in the cycle history menu.
    POSSIBLE CAUSE
    An electronic board was replaced when serviced.
    SOLUTION
    The memory of the old board can not be restored. Consult the cycle history in the USB pen drive.
  • When starting a cycle, the chamber door locks but re-opens immediately. The “Open the door” message appears.
    POSSIBLE CAUSE
    Door seal not properly placed.
    SOLUTION
    Ensure that the door seal is correctly inserted around the whole circumference.
    
    POSSIBLE CAUSE
    Door jammed by external objects or by the load itself.
    SOLUTION
    Remove any objects interfering with the chamber door. Check for interference between the door and the chamber furniture and/or the load.
  • The sterilizer enters into “Standby mode” immediately after being switched on.
    POSSIBLE CAUSE
    The unit was turned off while in standby mode.
    SOLUTION
    Press the standby mode button to exit.
  • The sterilization (PROCESS) phase of a sterilization cycle was longer than expected.
    POSSIBLE CAUSE
    The chamber temperature dropped below the minimum threshold and the software performed a successful recovery.
    SOLUTION
    Wait for cycle completion. If the problem occurs frequently, contact an authorized W&H service partner.
  • Warning about saving to the USB (HTML and SCL files)
    POSSIBLE CAUSE
    The USB mass storage is disconnected or full.

  • The sterilizer is connected to an automated water supply system, there is no clean water in the tank and the automatic water filling does not fill the water.
    POSSIBLE CAUSE
    Water filling system not connected.
    SOLUTION
    Connect the water filling system to the sterilizer. (see Instructions For Use).
    
    POSSIBLE CAUSE
    When the water filling system attempted to fill the tank, water was temporarily unavailable.
    SOLUTION
    Since the water tank filling is attempted only once in-between cycle execution, this event inhibits water feeding. Switch the sterilizer OFF and then ON again.
    Check the external water supply system.
    Check for water leaks from the sterilizer.
    
    POSSIBLE CAUSE
    Faulty MIN water level sensor in the clean water tank.

    A consumable needs to be replaced.
    SOLUTION
    Order the requested consumable (door seal and HEPA/bacteriological filter) and replace it. See the chapter “Maintenance” in the Instructions for Use.
  • What is the maximum noise level of the Lexa sterilizer?
    The max. noise level of Lexa is 65 dB.
  • Which water quality should I use for my sterilizer?
    The water quality for sterilizers is internationally specified by standards and directives. The reasons for this are that your sterilizer can be seriously damaged by it or the sterilization can be jeopardized. Consequently, only water with conductivity of less than 10 µS/cm should be used for your W&H sterilizer. The Multidem system is especially suited to preparing suitable water (see chapter “Water quality” in the Instructions for Use).
  • What periodic tests do I need to carry out on my Lexa sterilizer?
    Country/regional specific laws and guidelines referring to periodical testing or routine monitoring are individual and must be considered. Our recommendation for periodical testing is mentioned in the delivered IFU and depends on the integrated features in your sterilizer.
