The gun on my Karcher 520M leaks but only when the trigger is pressed, even after I replaced the o ring (PINK IN COLOUR!) on the metal part of the hose that enters the gun. I have taken off the four screws that hold the gun together but still cannot open up the gun to see what the problem is. First question is "how do I open up the gun to see what the problem is? Secondly what is the problem likely to be? Many thanks.
The gun needs replacing, non servicable, interchangable with many brands

It sounds like you left out the spring in the hose.
There are about 10 different models of K330 with several types of guns. Go here and search until you find the correct gun so you can see the diagram. I think it will be hard to buy a replacement spring, though.
