To set the cups in place. You can carefully bang them in place with a piece of wood in between them and the hammer but the press is way better.
When you take them off, clean them in kerosene or mineral spirits and a brush to get any gunk out. You can polish the outsides with wax after you put them back on. Throw away the old bearings and get new ones. Loose balls are best. Apply a bunch of waterproof grease like Phil Woods or automotive bearing grease into the cups then add the bearings. Completely fill the cup then remove one ball bearing. Complete reassembly.
By the way, that bike is one of mine. The headset was the only original part I reused on the bike.
