About

This is about a high volume, low pressure, air-powered spray gun - like the Purple Classic by Harbor Freight.

Let people know they are painting so they bring old clothes
Rags should be available - so gun is cleaned from spills readily.
Gun holder should be available for hanging gun for refills, with hose attached. Holder holds gun so strainer cup can be placed above cup.
Use 20 oz paint cups for longer spraying

Start at 80 PSI on regulator - it should be 40-60 PSI during operation, not when idle. Look at regulator.
Use an air/dirt filter
Air filter clean-out should be pointing down, by gravity
Turn air on all way at bottom of handle- and use regulator to set pressure
Use air pattern control to get spray wider or narrower - observe and practice with water.
Practice spray pattern with water onto a visible surface, such as stone, cardboard, fabric
Hang five for distance from work piece, hang five for spray width
Always keep gun direction at a normal to the surface sprayed. This means 2 dimensions.
If sheet is on floor, normal is impossible - the only way you can do it is if angle of substrate is near 45 degrees when working on panel material
Long material can be hung on a wall with blocks - if using a temp structure
Elevate panel on floor jacks as another option.

If you don't use it more than a few minutes - take off cup, take off air hose, leave gun suberged up to handle in about 6" of water immediately - for water-based paints.
Wipe gun with rags, so paint doesn't harden
For oil paints - if you're taking a break - do a diesel or mineral spirits blow-out
