The byproduct of using your chain drive garage door opener is that the hardware will begin to work itself loose. The vibrations that are caused by the garage door opener is the biggest cause of this happening. A few times a year you should take a ratchet, screwdriver, or adjustable wrench and give each of the nuts and bolts on the system a snugging. If you let this go for long enough you can have other problems, such as pieces falling and causing damage, or the chain binding and breaking.
