Regular cleaning and meticulous maintenance are essential to ensure that the spray gun is always in optimal condition.

Please refer to the product manual for the recommended spray pressure before using the spray gun.

The optimal spray distance for DeVilbiss spray guns is 15-20cm; being too close or too far may affect the actual spraying effect.

Air bubbles in the paint cup are caused by the nozzle not being tightened properly; therefore, tighten the nozzle securely.

The reason for this issue is mismatched needle-nozzle or excessive wear on the needle or nozzle. It is necessary to equip the spray gun with the correct nozzle and needle according to the standard.

Internal contamination of the main air valve or oversized sealing ring of the main air valve may cause air leakage.
