How Do You Operate An HVLP Paint Sprayer?
An HVLP paint sprayer is generally designed to handle both water-based and solvent-based coating materials. High volume, low pressure (HVLP) models are designed to reduce overspray and provide maximum transfer efficiency by limiting air cap pressure. • Mix the coating material to manufacturer’s instructions and strain material. • Fill the cup with the required amount of material. Fill to no more than 19 mm (3/4″) from the top of the cup. DO NOT OVERFILL. • Attach Cup Lid. • Turn fluid adjusting knob (18) clockwise to prevent fluid needle movement. • Turn spreader valve adjusting knob (23) counter clockwise to fully open. • Trigger the hvlp paint sprayer on and adjust inlet air pressure (for recommended figures see Chart 1 under Parts Replacement) at the gun inlet. (Pressure gauge shown under Accessories is recommended for this). • Turn the fluid adjusting knob counter clockwise until first thread shows. • Test spray. If the finish is too dry, reduce airflow by reducing air inlet pressu

If the finish is too dry, reduce airflow by reducing air inlet pressure. • If finish is too wet, reduce fluid flow by turning fluid adjusting knob (18) clockwise. If atomisation is too coarse, increase inlet air pressure. If too fine, reduce inlet pressure. • The pattern size can be reduced by turning spreader valve ad
