Why is no liquid getting to the pump on my Hardi Paint Sprayer?
If your Hardi Paint Sprayer isn't spraying liquid, it could be due to a plugged suction tube, a valve on the suction manifold being incorrectly positioned, or an air leak in the suction filter O-ring.
Why is my Hardi Paint Sprayer lacking pressure?
If your Hardi Paint Sprayer is experiencing a lack of pressure, several factors could be responsible. The bottom of the suction tube might be plugged, or the motor shaft coupling could be loose or have a missing fork pin. Other potential causes include a bad seat on the spool valve for boom section control, insufficient PTO speed, an incorrectly positioned valve on the suction manifold, a faulty suction valve, a suction side air leak, a disengaged PTO, incorrectly positioned valves on the pressure manifold, or worn or missing agitation nozzles.
Why is the pressure jumping on my Hardi Paint Sprayer?
If the pressure in your Hardi Paint Sprayer is jumping, it could be due to several reasons. The output from the by-pass lines might be causing a disturbance around the suction hose. Alternatively, there could be a small tear or pinhole in the suction hose, the PTO shaft might be slipping on the pump shaft, there could be a bad suction valve or suction side air leak, or the valves on the Pressure Manifold might not be in the correct position.
What to do if there is no power supply to the control box of my Hardi Paint Sprayer?
Check all connections and cables in the power supply of your Hardi Paint Sprayer.
What to do if the boom won’t go up or down on my Hardi Paint Sprayer?
H-frame needs to be greased on your Hardi Paint Sprayer.
Why will my Hardi Paint Sprayer system flush but not rinse?
If the system on your Hardi Paint Sprayer will flush but not rinse, ensure the Pressure Manifold valve is in the correct position, with the arrow on the handle pointing towards the rinse nozzle symbol.
Why does the rinse nozzle have poor output on my Hardi Paint Sprayer?
If the rinse nozzle on your Hardi Paint Sprayer has poor output, it could be due to a bad Suction Manifold valve or suction side air leak, the Pressure Manifold valve not being in the correct position, or the Chemical filler Pressure Manifold valve being in the correct position (if so equipped).
Why won't the compressor run on my Hardi Paint Sprayer?
If the compressor on your Hardi Paint Sprayer will not run, it could be due to a short in the electrical system, a bad compressor, a 12 volt supply not connected, a bad printboard, or a defective switch in the control box.
Why can't I get the tank empty on my Hardi Paint Sprayer?
If you can't get the tank empty on your Hardi Paint Sprayer, it could be due to the output from the by-pass lines causing a disturbance around the suction tube, a crack or pin hole in the suction tube, or the tank not being level.
