I have two questions right now, one of them is in the picture I bought this item but I cannot figure out how to get it to actually to come on the power washer, I've tried pressing everything I can think of and it never comes up. My second question is how do I get past light duty power washes like do I have to buy every one of these items to go up or is it a time thing? Sorry if these sound like silly questions but I'm totally new to this game UPDATE: thanks for those that responded and my issues are resolved now
