I recently acquired a Porter Cable 6 gallon oilless "pancake" compressor with finish nailer, brad nailer and stapler for a large project; I've finished the project now - these tools are seriously wonderful, they saved me loads of time and hassles. I'll be using them off and on, probably pull the compressor out about once a month for working on the car or something, and use the nailers for a project maybe once or twice a year.
So, I'm wondering now about care and feeding - now that this project is done, I'll be an infrequent, low-volume user, so what should I pay attention to for storage? They'll be stored in a cool basement, not damp and up on shelves in their original boxes. I've drained the compressor, but should I leave the drain valve open or should I close it? And oiling the nailers; the instructions say 5-6 drops each use, but that seems like a lot - how much oil should I use for a dozen quick shots? Does it matter, and will the tools gum up if I use too much oil and then leave them on the shelf for a year?
Sorry if these questions seem basic, but I've not had any previous experience with pneumatic tools, and the instructions didn't address storage. I'd like these tools to last; any advice would be appreciated, thanks!
