Maintenance and Cleaning Instructions
- Before using it for the first time, perform a visual and mechanical check to ensure that the file is working properly
- During its use, it is important to remove any visible residue to prevent it from becoming embedded and corroding the steel
- After use, it is essential to remove residues immediately, avoiding exceeding the 1-hour time threshold
- It is preferable to opt for dry cleaning to prevent signs of wear or corrosion over time
- If dry cleaning is insufficient, it will be necessary to use cold water, applying it under pressure in grooves, cavities or hard-to-reach holes
- If this last step is also insufficient, you can use a plastic brush with soft bristles
- If you are not going to proceed immediately with disinfection, thoroughly dry the instrument with an absorbent cloth that does not leave residues to prevent corrosion; in the case of cavities and hard-to-reach grooves, use compressed air

Disinfection Instructions
- To disinfect it, immerse it in a solution of distilled water with a compatible disinfectant according to the manufacturer's instructions
- Make sure the disinfectant product comes into contact with the entire surface of the instrument, emphasizing hard-to-reach areas
- Do not place the instrument in contact with other tools to prevent overlapping and inadequate disinfection
- At the end of cleaning, rinse the file with plenty of cold distilled water and dry thoroughly with an absorbent cloth that does not leave residues

Sterilization Instructions
- It is recommended to apply a layer of steam-permeable protective oil to keep the instrument properly lubricated; before proceeding with sterilization, remove excess oil with a non-residue-releasing cloth
- Sterilize the file according to current regulations; in Europe, steam sterilization cycles are a minimum of 15 minutes at 121ºC and 110 kPa or 3 minutes at 134ºC at 210 kPa

Usage Precautions
- Avoid using saline solutions, chlorinated, acidic salts, iodine tinctures, or products not suitable for stainless steel
- Do not wait long periods of time for reprocessing to prevent blood, pus, secretions or contaminants from corroding it
- Do not use the material for operations not contemplated in its manufacture
- Do not clean the instrument with abrasive materials to avoid erosion on its surface
- Do not subject the file to an ultrasonic bath with other instruments that are not made of stainless steel to prevent reduction-oxidation effects
- Dry the instrument properly each time it is immersed in a water solution, using compressed air tools if necessary
- The product is supplied in non-sterile conditions, so it must be properly treated before use and each time it is to be reused
- Store the file in a cool, dry place, protecting it from direct sunlight
