If you have a hose with a make quick connect, it's most likely an air hose. For compressed air, open the "hood" like you're accessing the generator. Look on the driver side up high and you'll see a female quick connect that allows you to tie into the air system. You can use this to air up your tires so long as the engine (and thus the compressor) is running.
As for bypassing the hydraulic pump, you should have received a tool that looks sort of like a flexible screwdriver that fits in a drill. The end is an Allen wrench (hex key). If the hydraulic pump goes out, you use this tool with a drill to work the system manually. It requires you to set the calving manually, so you'll need to read up on that if it's ever needed.
