What type of maintenance involves cleanings, adjustments, and testing?

The correct answer is preventive maintenance. This type of maintenance is proactive and focuses on routine tasks such as cleaning, adjustments, and testing. The goal of preventive maintenance is to reduce the likelihood of equipment failure by identifying and addressing potential issues before they become serious problems.

Regular cleaning helps maintain equipment in optimal condition, while adjustments can ensure that machinery operates efficiently and effectively. Testing verifies that systems are functioning as intended. By carrying out these activities consistently, organizations can extend the lifespan of their assets and minimize downtime.

Scheduled maintenance, while related to preventive maintenance, typically refers more broadly to maintenance tasks that are planned and carried out at regular intervals. Emergency maintenance occurs in response to an unexpected failure or urgent situation, and corrective maintenance involves fixing equipment after a fault has occurred. These types of maintenance do not primarily involve the routine cleanings, adjustments, and testing focused on preventing issues from arising in the first place.
