Step 5: Test the Door

Once you’ve made the necessary adjustments, it’s time to test the garage door. Open and close it a few times to ensure it moves smoothly and without any unusual noises.

Step 6: Lubricate the Chain

To keep your garage door chain in good condition, apply some lubricant. This will reduce friction and extend the life of the chain.

Step 7: Tighten the Chain Tension Nut

When you’re satisfied with the results, use your wrench to tighten the chain tension nut back to its original position.
