Arizona State Board Nail Technology Practice Exam

What practice will extend the life of the motor on an electric file?

1. Keeping the motor fully exposed

2. Using the file only on natural nails

3. Proper use and maintenance

4. Using it at the highest speed

The correct answer is: Proper use and maintenance

Proper use and maintenance of an electric file significantly contributes to extending the life of its motor. This includes regularly cleaning the unit to prevent dust and debris buildup, ensuring that the bits used are suitable for the file to prevent unnecessary strain on the motor, and making sure to follow the manufacturer’s guidelines for usage. Regularly checking the file for wear and tear, and replacing parts as needed also helps maintain optimal performance and longevity of the motor. Implementing these practices reduces wear on the motor, allowing it to function more efficiently over time. Other practices, such as keeping the motor fully exposed, can lead to contamination and damage; using the file only on natural nails may limit the time the file is effective but does not address overall motor maintenance; and using it at the highest speed can result in overheating and increased wear, which negatively affects the motor's lifespan.
