I see the wooden top on the left of your machine is sagging down a fair amount.......
Check on the left vertical side of your cabinet - there should be a metal arm there that is supposed to pop out when the lid is lifted. If it's not 'out' just give it a helping hand and it should come out easily. It should come out at approximately 45 degrees to the front. Once it's out lay your top lid on it. Might want to give a spritz of oil on the arm hinge...
Nice machine! You will love it!
