	2.	Incorrect paint volume	2.	Adjust Fluid Control Knob (12)
	3.	Insufficient air pressure	3.	Adjust Air Regulator (37) and Air
				Adjustment Valve (31)
	4.	Paint gun too far from paint	4.	Hold spray gun closer to surface
		surface during spraying		during spraying.
Paint sags or runs	1.	Excess thinning of paint	1.	Recheck paint viscosity. Add
