Check air pressure to gun; minimum

 

 

 

40 psi (0.28 MPa, 2.8 bar) needed at

 

 

 

gun for full voltage.

 

 

 

 

 

 

Atomizing air pressure too high.

Decrease.

 

 

 

 

 

 

Fluid pressure too high.

Decrease.

 

 

 

 

 

 

Incorrect distance from gun to part.

Should be 8-12 in. (200-300 mm).
