  If the wiwa Paint Sprayer pump runs but doesn't convey material, several issues could be the cause: * The spray gun might be clogged. Check, clean, and replace the nozzle or filter element if needed. * The relief hose or ball valve might be clogged. Clean or replace them. * The air motor could be defective. Repair it using the spare parts list, or contact customer service if necessary. * The suction strainer might be clogged. Clean or replace it. * The suction hose might be clogged. Replace the hose.

  If your wiwa Paint Sprayer pump is running smoothly, but you are not achieving the required spray pressure, consider these potential causes: * The air pressure might be too low or there is too little air. Increase the air pressure on the compressed air regulator or check the air line for the correct cross-section. * The spray nozzle might be too large. Insert a smaller nozzle or use a larger pump. * The spray nozzle might be worn. Insert a new nozzle.

What to do if my wiwa GX pump conveys material, but doesn't stop when the spray gun is closed?

  If the wiwa Paint Sprayer pump continues to convey material even after the spray gun is closed, it could be due to: * The ball in the bottom valve is stuck. Open the spray gun without the nozzle and the relief valve on the high-pressure filter. Gently move the bottom valve with a slight impact. Alternatively, unscrew the suction system and press the ball out from the bottom using a pin or screwdriver. * The bottom valve isn't closing properly. Unscrew the bottom valve and thoroughly clean the ball and the seat. * Some parts may need replacement.

  If your wiwa Paint Sprayer pump isn't running consistently, and you notice variations in stroke speed, and it's not reaching the required spray pressure, check the following: * The viscosity of the spraying material may be too high. Dilute the spray material. * The suction system may be leaking. Check the seals on all threaded connections of the suction tube and the suction hose, and replace them if necessary. * The bottom valve may be leaking. Unscrew the bottom valve and clean the ball and the seat thoroughly; replace the ball or valve seat if needed. * The piston valve may be leaking. Clean and check the ball and seat in the double piston; replace the valve seat as required. * The lower or upper packing may be leaking due to wear. Replace the sleeve sets. * The packings may...
