Basically: Go around his tail and throw the lever on his back, and when he opens his mouth shoot the ice arrow. (repeat 2 more times)

Further info
As soon as you enter the lair, climb the chains and work your way across the top. If you are high enough, it is quicker to jump than climbing every chain. If you approach from behind, you won't be zapped. Dodge the spike ball at his tail and reach the lever on his back. (*The lever must be in the back position and the spike ball working.*) Throwing the switch will put him to "sleep" for JUST A FEW SECONDS. VERY QUICKLY jump in front of him and fire the Ice Arrow directly into his mouth. (This should make him flash red and jump up and down.) Repeat the same thing twice more, but it will be complicated by dodging falling stalactites from the ceiling. You can likely survive one miss without failing the round. If you overheat, you must start over.
* When you win, the dragon falls down below, but the Princess isn't there, so you have to search for her on the other planets.
