As an Oil Filter Wrench Manufacturer, we have the following recommendations for the daily maintenance of spray guns.
1. Cleaning of the spray gun
Immediately after use, the gun and its accessories should be cleaned. Unscheduled maintenance and cleaning are the main causes of gun failure.
When cleaning the suction feed gun, first remove the paint can and flow the suction tube into the cup. Then release the air cap 2-3 turns, block the air cap with a folded rag, and then pull the trigger. This allows the paint in the gun to flow back into the paint can.
Note: The air pressure used should be low. When the paint can is still mounted on the gun, do not perform the above operation, otherwise the paint will splash out of the tank.
Retighten the air cap and pour the paint from the paint canister back into the original large can. Clean the inside of the cup and the lid with a solvent and a thin brush. Wipe off the residue with a cloth dipped in solvent. Then pour a little clean detergent into the cup, pull the trigger, spray the cleaner, and clean the feed tube. Then remove the air cap, soak in a thinner or solvent, and clean the clogged pores with a soft brush like a round-headed toothbrush or a straw broom. Remember, you should never clean these holes with something like iron wire or nails, because these holes are all precision drilled. Wipe the outside of the Air Spray Gun with a cloth dampened with thinner, taking care to wipe off any traces of paint.
