Step 1: Connect from the Power Supply and turn off the Opener.

Before you start working prior to starting work, you should be aware of the precautions you can take to protect yourself. First, make sure your garage is secure.

Once you have adjusted your chain to the right tension then tighten your locking bolt. It is recommended to employ two wrenches when doing this, one for holding the adjustment nut and the other one is used to turn on the lock nuts.

Step 4: Connect the Power, then re-engage the Opener

This will trigger the trolley to to snap back into place instantly. If you engage the opener again , you might notice that the chain starts to relax a little. It's normal. The chain will be able to regain tension once it is in an open position.
