That was an incredible buy, and with the case and attachments, too! Congratulations! You will have many happy hours with this machine.
I have a 301 long bed I call JoyBoy because he is such a joy to use. These machines are bullet proof. Just oil every 8 hours and keep it clean, and you will be fine.
BTW, look for the quarter inch slant foot. It is worth having. It is an aftermarket foot.
