Well, I finished my second job. The hour glass lines are still there. I didn’t change the hose yet. I bought this machine used. The guys had done 3 jobs with it, in September of last year. I picked it up in January. I’d hate to change to a 3/8x 50 ft hose, but if that makes the lines straight, I guess I’ll have to do it. The Titan manual for this 2800M really doesn’t give much help. When I hit the trigger to spray the paint, is the pump supposed to work all the way through? The pump shuts off, then kicks in a couple of times throughout the 18 foot line. When it kicks in, the line widens.
Maybe I need to crank the pump up so it runs every second the trigger is pulled?
