Why is there excessive overspray with my DeVilbiss Paint Sprayer?
Excessive overspray from your DeVilbiss Paint Sprayer can occur if the air pressure is too high or if the gun is too far from the work surface. Try reducing the air pressure and adjusting the distance to the correct range.
What to do if my DeVilbiss SRI PRO Paint Sprayer has a heavy center pattern?
A heavy center pattern with 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, or thin the material to the correct consistency.
How to fix dry spray with DeVilbiss SRI PRO Paint Sprayer?
Dry spray from your DeVilbiss Paint Sprayer can be caused by several factors: air pressure being too high, holding the gun too far from the work surface, moving the gun too fast, or having fluid flow that is too low. Try reducing the air pressure, adjusting the distance, slowing down your motion, or winding out the needle adjusting screw or using a larger nozzle size.
What to do if my DeVilbiss SRI PRO Paint Sprayer produces runs and sags?
Runs and sags when using your 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 moved too slowly. Try turning the fluid adjusting knob clockwise or switching to a smaller fluid nozzle and needle size, mixing the material correctly or applying light coats, and holding the gun at a right angle to the work while adapting to the correct gun technique.
Why is my DeVilbiss SRI PRO Paint Sprayer spraying a split pattern?
A split spray pattern from your DeVilbiss Paint Sprayer may be due to air pressure being too high, the fluid adjusting knob turned in too far, or the spreader adjusting valve set too high. Reduce the air pressure at the regulator or gun handle, turn out the fluid adjusting knob counterclockwise to achieve the correct pattern, or turn in the spreader adjusting valve clockwise to achieve the correct pattern.
What causes jerky or fluttering spray from a DeVilbiss Paint Sprayer?
Jerky or fluttering spray from your DeVilbiss Paint Sprayer can result from several issues: a loose or damaged fluid nozzle/seat, a loose or broken cup fluid nipple, the 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. You can try the following: 1. Tighten or replace the fluid nozzle/seat. 2. Tighten or replace the cup fluid nipple. 3. Refill the material. 4. Hold the container more upright. 5. Back flush with solvent to clear any obstruction. 6. Tighten the fluid needle packing nut. 7. Replace the fluid needle packing.
What to do if my DeVilbiss SRI PRO has a starved spray pattern?
A starved spray pattern with your DeVilbiss Paint Sprayer may 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, cleaning the lid and unblocking the vent, or increasing the air pressure and rebalancing the gun.
How to resolve a heavy top, bottom, right, or left side pattern on my DeVilbiss SRI PRO?
If your DeVilbiss Paint Sprayer is producing a heavy top, bottom, right, or left side pattern, it could be due to plugged horn holes, an obstruction on the fluid nozzle, a dirty cap and/or nozzle seat, or dirt on the fluid nozzle. Clean the affected parts and ream with a non-metallic point if necessary.
Why is fluid leaking or dripping from the front of my DeVilbiss Paint Sprayer?
Fluid leaking or dripping from the front of your DeVilbiss Paint Sprayer can occur if the fluid nozzle or fluid needle is worn or damaged, there's foreign matter in the fluid nozzle, the fluid needle is dirty or stuck in the needle packing, or the wrong size fluid needle or fluid nozzle is being used. Try replacing the fluid nozzle and fluid needle, or cleaning the affected parts.
Why does my DeVilbiss Paint Sprayer have paint bubbles in the cup?
Paint bubbles in the cup of your DeVilbiss Paint Sprayer are often caused by a fluid nozzle that is not tight. Tighten the fluid nozzle to 9-10 Nm (80-90 in-lbs).
