Lubricating the door spindle of your MELAG autoclave

How to check the spindle nut and spindle of your MELAG autoclave - step-by-step instructions

Modern MELAG autoclaves, like the premium Vacuclave 550, Cliniclave 45, and the versatile Careclave, feature automated door locks that save time and ensure secure sterilization. Regular maintenance is crucial to keep your device in top working condition and extend the lifespan of its door lock mechanism. In this tutorial, we’ll walk you through the steps to inspect and lubricate the spindle nut and spindle of your MELAG autoclave using MELAG oil.

Step 1: The need for regular inspection

Checking the spindle nut and spindle is a simple but crucial measure to ensure that the door lock is working properly. MELAG recommends carrying out this maintenance approximately every two months. A well-maintained door lock contributes to the longevity of the appliance and prevents unnecessary downtime.

Step 2: Cleaning the spindle and spindle nut

Materials required: lint-free cloth

Start maintenance by cleaning the spindle and spindle nut:

Use a lint-free cloth to remove any dirt and dust particles from the spindle and spindle nut.
Be sure to clean thoroughly to ensure that there is no residue on the components. A clean spindle is essential so that the oil can be optimally absorbed and distributed later.

Step 3: Checking the spindle nut with the test gauge

Materials required: Test gauge

Now check the spindle nut:

Take the test gauge and insert it into the spindle nut as far as it will go.
Turn the test gauge 180 degrees.
Pay close attention to the feel of the rotation: If you feel resistance when turning or the test gauge cannot be turned, this may indicate that the spindle nut is worn.
- Tip
  If wear is detected, please contact an authorized MELAG service technician to have a further check and any necessary repairs carried out.

Step 4: Lubricating the Mechanism with MELAG Oil

Materials Needed: MELAG oil (Item Number ME27515)

To maintain a smooth-functioning door lock, regular lubrication with MELAG oil is essential:

Apply two drops of MELAG oil directly into the spindle nut.
Close the autoclave door—this action will automatically distribute the oil evenly within the locking mechanism.
The oil helps prevent early wear, promoting the lock’s smooth operation.

Step 5: Completing the Maintenance

After cleaning, checking, and oiling, your autoclave is ready for normal use. Be sure to use only original MELAG oil for this maintenance task to maintain your device’s functionality and safety. For further questions or concerns, contact your authorized MELAG service partner.

Conclusion

These simple maintenance steps can greatly extend the life and performance of your MELAG autoclave’s door lock. Regular care with MELAG oil and careful inspection of the spindle nut helps prevent unnecessary wear and ensures safe, reliable operation.
