I heard this level 1 was crappy, so I never bothered with him. I do badly with people who's level 1 is crappy.

You need to harass him, don't let him set up shop. Jak's square moves are going to better off for you here than his guns, but make sure you use everything you have at your disposal. If you have any say in what stage it is, try to make sure it's the Dojo or one of the practice stages that has no platforms/ledges. If he's at one side of the map with his fan and shock pad, jump towards him and hit down circle, as it will hit him and destroy his gadgets, plus you can combo off of it.
