By the time Winry had finished washing her hands and was in the process of drying them with her rag, Annabelle had pretty much gotten herself ready. Winry had to admit she was a little nervous, as she'd never dealt with someone who was fully automated like this before, but she was a professional regardless. She did her best to not make the situation awkward, because she always wanted her customers to have the best experience possible. It wasn't even about making a profit or anything like that for her, but simply because she figured that people with automail already had a lot to deal with in their lives. Why add to the stress and aggravation for no reason?
She smiled and went over to grab her tools, pulling out several different types of wrenches and screwdrivers. Her eyes pinpointed the spots on Annabelle's body that had screws in them long before she'd told her. She was just used to seeing things with automail-colored glasses, so to speak. She had seen so many different kinds of automail by now that her eyes were used to spotting the converging points. Without further ado, she proceeded to unscrew as many connectors as she could find. If she was going to get to the bottom of whatever was ailing Annabelle, she had to really get in there to check things out thoroughly. Expertly, she worked at removing the exterior casings to unveil the mechanism underneath, marveling at the handy work the whole time.
It wasn't long before Winry had Annabelle looking like an open cabinet, taking note of all the parts she could see that needed some work. She had all of her screws neatly lined up on the table so as to keep them in order for when she needed to put them all back, all the while making thoughtful faces at she went. "Well... the good news is that there isn't anything major that I can tell so far that's off," she commented lightly. Every once in a while, she would use her screwdriver to tap on a few of the metal plates just to hear the sort of sound they made. "I have located a few areas that need work though, mostly maintenance and upkeep. There's a bit of oxidation going on in some areas, but with regular cleaning we can easily deal with that. What I'm most worried about though is this arm plate here..."
Annabelle had said her arm was bothering her, and upon inspection and through the sound it made when tapped on, Winry could tell it needed to be replaced. "The metal is getting a little too malleable here, which isn't any kind of emergency right now, but I'm afraid that if it's left alone, it'll only continue to weaken as time passes. You wanna have a nice combination of sturdy and malleable metal to give you a good range of motion without compromising the strength of the limb." She stepped back for a moment to collect her thoughts and to see if there was anything else she was missing. "By chance, do you know what type of metal was used when you were made?"
