Being a new guy with no experience myself, all I can recommend is to take your time and explore the machine. Cleaning, adjusting and repairing minor issues allow you to become familiar with how the machine works. This forum is an awesome group of people who will answer any question you have, so don't be afraid to ask for help. Nobody will give you a hard time about "stupid" questions here, so do not be afraid to ask. Make sure that you work safely, being focused on doing something new can cause you to forget safety.
Congratulations and enjoy your new toy!
