HF HVLP question

[wedge40]

I got a couple of Harbor Freight sprayers Sunday. (Harbor Freight Tools - Quality Tools at the Lowest Prices. Inside the box is a wrench/tool, small filter to put between the cup and sprayer, a small brush for cleaning. AND? 4 little pins. Anybody know what these pins are for?

Probably for clearing orifices.

Now that you mention that. They are about the same size as the spary holes in fluid nozzle. I'm guessing four cause they will get lost.
Thanks.

I have a sherwin williams 4900 hvlp. Those pins are for different viscosities of fluid. If you look close you will see they are different sizes. Small for auto type paint. Large for latex, in between for oil and urethane.
