Ideally, you'd be smart, and just figure out your problems without bothering me. But, sadly, I realize that some people are real dummies, and need some handholding once in a while. (I'm kidding, I'm kidding!)
First of all, instructions for the Dual Chain Planetary clock can be downloaded here. Most of the instruction steps for that clock are applicable to the others as well. I have confidence in you as a person, in that you can make sense of it.
For any and all questions or issues regarding your purchase, please send an email to email@example.com and I'd be happy to help out. This includes everything from broken/missing parts (yes, I know, you're just clumsy and drop things, or the cat was bad, as cats are) or general issues.
