Frequently Asked Questions - RP8623S Vevor
What size air compressor is needed for the Vevor RP8623S paint gun?
Use a compressor that can maintain at least 4.5 CFM at the gun's operating pressure of 25–40 psi, typically a 2.5 hp or larger compressor with a 1/4" fitting.
How do I adjust the spray pattern width?
Turn the pattern control knob at the rear of the gun to change from a round spot to a wide fan. Then use the fluid adjustment knob to regulate the amount of paint flowing to match the pattern.
How should I clean the gun after painting?
Empty the cup, fill it with a compatible thinner or solvent, spray it through the gun, then disassemble the nozzle, needle and air cap and wipe them clean with a soft cloth.
What types of paint can be sprayed with this gun?
It can spray automotive paints, primers, clearcoats, enamel, acrylic, varnish and stains, provided the material is thinned to the right viscosity for a gravity-feed HVLP gun.
Why does the spray gun spit or sputter?
Spitting is usually caused by a loose fluid cup, a blocked cup air vent, a loose nozzle, or air leaking into the fluid passage. Check these parts and make sure the cup is full enough.
What is the correct spraying distance?
Keep the nozzle 6 to 8 inches from the surface. Move your arm smoothly and parallel to the work piece to get an even coat without runs.
How can I prevent paint runs and sags?
Apply thin, even coats and avoid staying too long in one spot. Do not overload the surface and let each coat flash off before applying the next one.
Can I spray water-based latex paint?
Yes, but the latex must be thinned with water to a milky consistency and filtered to avoid clogs. Clean the gun immediately after use to prevent cured latex from damaging the internal parts.
How do I replace the nozzle or needle?
Unscrew the air cap, pull out the needle spring assembly, then use the included wrench to unscrew the nozzle. Install the new nozzle and needle by reversing the process.
What safety precautions should I take when using this gun?
Always wear a respirator and safety goggles, work in a well-ventilated area and keep the gun away from sparks and flames. Disconnect the air supply before cleaning or servicing.
