How can I properly adjust my garage door to ensure it functions smoothly and safely?

To properly adjust your garage door for smooth and safe operation, you should first check the balance of the door by testing the springs and adjusting them if needed. Next, lubricate the moving parts of the door to reduce friction. Ensure that the tracks are aligned and clean, and adjust the track spacing if necessary. Finally, test the safety features of the door, such as the auto-reverse mechanism, to make sure they are functioning correctly.
