Krause and Becker. Model 60446. Paint spray gun. When you paint you have to clean all parts. The directions say remove nozzle and then pull out nozzle assembly and the show a picture of the parts. I have pull on the nozzle assembly bu hand and nothing moves. Just bout today. Never used but I can not paint if I do not know have the thing comes apart to be cleaned. First harbor freight tool owned. Thought some one might have one and would know how to take it apart. Thanks
