What to do if my DeVilbiss GTI PRO LITE has excessive overspray?
If your DeVilbiss Paint Sprayer is producing excessive overspray, it's likely due to the air pressure being too high or holding the gun too far from the work surface. Try reducing the air pressure and adjusting the distance to the correct range.
Why does my DeVilbiss Paint Sprayer have runs and sags?
Runs and sags in your spray finish from the DeVilbiss Paint Sprayer can occur if there's too much material flow, the material is too thin, or the gun is tilted at an angle, or the gun motion is too slow. To fix this, turn the fluid adjusting knob clockwise or switch to a smaller fluid nozzle and fluid needle size. Ensure your material is mixed correctly, or apply light coats. Hold the gun at a right angle to the work and adapt the correct gun technique.
How to fix a DeVilbiss Paint Sprayer that has a starved spray pattern?
A starved spray pattern on your DeVilbiss Paint Sprayer can be caused by inadequate material flow, a blocked vent in the cup lid, or low atomization air pressure. Try winding the fluid adjusting knob out or changing to a larger fluid nozzle size. Clean the lid to unblock the vent. Increase the air pressure and rebalance the gun.
What to do if my DeVilbiss GTI PRO LITE Paint Sprayer has a dry spray?
If your DeVilbiss Paint Sprayer is producing a dry spray, the issue might be that the air pressure is too high, the gun is too far from the work surface, the gun motion is too fast, or the fluid flow is too low. Reduce the air pressure, adjust to the correct distance, slow down your motion, and wind out the needle adjusting screw or use a larger nozzle size.
How to resolve a jerky spray from my DeVilbiss GTI PRO LITE Paint Sprayer?
A jerky or fluttering spray from your DeVilbiss Paint Sprayer can be caused by several factors: a loose or damaged fluid nozzle/seat, a loose or broken cup fluid nipple, material level being too low, the container being tipped too far, an obstruction in the fluid passage, a loose fluid needle packing nut, or damaged fluid needle packing. Suggested solutions include tightening or replacing the fluid nozzle/seat or cup, refilling the material, holding the container more upright, back flushing with solvent, and tightening or replacing the fluid needle packing.
What causes a split spray pattern in my DeVilbiss GTI PRO LITE Paint Sprayer and how do I fix it?
A split spray pattern from your DeVilbiss Paint Sprayer can be caused by air pressure being too high, the fluid adjusting knob turned in too far, or the spreader adjusting valve set too high. To correct this, reduce the air pressure at the regulator or gun handle. Turn out the fluid adjusting knob counterclockwise to achieve the correct pattern. Turn in the spreader adjusting valve clockwise to achieve the correct pattern.
Why is my DeVilbiss GTI PRO LITE producing a heavy center pattern?
A heavy center pattern from your DeVilbiss Paint Sprayer may be due to the spreader adjustment valve being set too low, the atomizing pressure being too low, or the material being too thick. Turn the spreader adjustment valve out counterclockwise to achieve the correct pattern. Increase the pressure. Thin the material to the correct consistency.
How do I fix a DeVilbiss GTI PRO LITE with a heavy top/bottom or right/left spray pattern?
If your DeVilbiss Paint Sprayer is producing a heavy top or bottom pattern, or a heavy right or left side pattern, it could be due to several reasons: plugged horn holes, an obstruction on the top or bottom of the fluid nozzle, a dirty cap and/or nozzle seat, or dirt on the left or right side of the fluid nozzle. Clean or ream with a non-metallic point.
