Why is paint bubbling in the cup of my DeVilbiss Paint Sprayer?
If you notice paint bubbles in the cup of your DeVilbiss Paint Sprayer, it's likely that the fluid tip is not tight. Tighten the tip to resolve this issue.
How to prevent runs and sags with DeVilbiss FLG4 Paint Sprayer?
Runs and sags when using your DeVilbiss Paint Sprayer can happen if there's too much material flow, the material is too thin, or if the gun is tilted at an angle, or moved too slowly. Adjust the gun or reduce fluid flow, properly mix the material or apply light coats, and hold the gun at a right angle to the work surface, adapting proper gun technique.
Why is my DeVilbiss Paint Sprayer producing a dry spray?
Dry spray from your DeVilbiss Paint Sprayer can be due to several reasons: the air pressure is too high, the gun tip is too far from the work surface, or the gun motion is too fast, or the gun is out of adjustment. Reduce the air pressure, adjust to the proper distance, slow down your motion, and adjust the gun.
How to get round spray with DeVilbiss Paint Sprayer?
If you're unable to get a round spray from your DeVilbiss Paint Sprayer, it could be that the spreader adjustment screw is not seating properly or the air cap retaining ring is loose. Clean or replace the spreader adjustment screw, and tighten the air cap retaining ring.
How to fix thick, dimpled finish "orange peel" with DeVilbiss Paint Sprayer?
A thick, dimpled finish or "orange peel" effect can occur if the gun is too close to the surface, too much material is coarsely atomized, the air pressure is too low, an improper thinner is being used, the material is not properly mixed, or the surface is rough, oily, or dirty. To resolve this, check the distance (normally approximately 8 inches), follow the paint manufacturer's mixing instructions, increase air pressure or reduce fluid flow, and properly clean and prepare the surface.
Why am I unable to get a round spray with my DeVilbiss Paint Sprayer?
If you're unable to get a round spray with your DeVilbiss Paint Sprayer, it may be because the spreader adjustment screw is not seating properly or the air cap retaining ring is loose. Clean or replace the spreader adjustment screw and tighten the retaining ring.
Why does my DeVilbiss FLG4 have a split spray pattern?
A split spray pattern from your DeVilbiss Paint Sprayer can be caused by atomization air pressure being too high, fluid flow being too low, or the spreader adjusting valve set too high. Reduce the air pressure at the transformer or gun, increase fluid flow to increase gun handling speed and adjust the spreader adjusting valve.
What causes a heavy center pattern with DeVilbiss FLG4 Paint Sprayer?
A heavy center pattern with your DeVilbiss Paint Sprayer can occur if the fluid flow is too high for the atomization air, the material flow exceeds the air cap's capacity, the spreader adjustment valve is set too low, the atomizing pressure is too low, or the material is too thick. Balance air pressure and fluid flow, increase the spray pattern width with the spreader adjustment valve, thin or lower fluid flow, adjust the pressure, and thin the material to the proper consistency.
Why does my DeVilbiss FLG4 have a heavy right or left side pattern?
A heavy right or left side pattern is caused by left or right side horn holes that are plugged or dirt on the left or right side of the fluid tip. To fix this, clean the affected parts and ream with a non-metallic point.
Why does my DeVilbiss FLG4 Paint Sprayer have a jerky or fluttering spray?
A jerky or fluttering spray can occur if the fluid tip/seat is loose or damaged, the material level is too low, the container is tipped too far, there's an obstruction in the fluid passage, or the fluid needle packing nut is dry or loose. To resolve this, tighten or replace the fluid tip/seat, refill the material, hold the container more upright, backflush with solvent, and lubricate or tighten the packing nut.
