This gun is so clean, you can see your reflection in the aluminum.

Now get the schematic for the gun and break the gun all the way down.
Take it down to the seals, O rings, and packings and return springs.
Don't worry about taking this gun apart; it is a great gun, and made
to be used hard and rebuilt. You won't hurt a thing.

Check the needle when you pull it out. If there is the smallest
amount of anything on it, it is almost a sure indicator that something
is in the barrel. You need to make sure you have the gun cleaning kit
around to get this done properly. BTW, in case one didn't come with
your gun, it is a tiny bottle brush, something that looks like a small
toothbrush, and probably some toothpick looking pieces of wood to
clean the pressure cap assembly.

Still nothing? The next culprit is the pickup tube and its connection
to the gun body/barrel. Remove it from the gun and look inside the
housing. Remove any debris, looking carefully at the hole where the
fluid enters the barrel before atomizing. This is where mine gets
gunked on occasion.

Then check the pickup tube itself. Make sure it is as clean as
possible inside.


Most pickup problems like this are the result of clogs in the gun head which
require exactly the procedure Robert describes. Pay particular attention to
the pickup tube and pathways associated with it. The gun relies on a
venturi effect to pull the material out of the cup and problems like this
are almost always caused by obstructions.
