Why KUHN Omnis Paint Sprayer has lack in pressure?
- C
  Caroline TurnerAug 21, 2025
  If you're experiencing a lack of pressure in your KUHN Paint Sprayer, and it's related to ground speed, adjust the ground speed to match the programmed application rate. If the pressure gauge is faulty, replace it. If the nozzle is worn, check its output and replace it if necessary. Verify the flowmeter and speed information for coherence with the control box. For incorrect control box settings, consult the control box operator's manual.

Why the pressure on the gauge drops in KUHN Omnis?
- L
  Laura SnyderAug 25, 2025
  If the pressure on the gauge of your KUHN Paint Sprayer drops, it could be due to swirl during suction on the tank bottom, so reduce the PTO speed. A clogged suction filter can also cause this, so clean the filter. Check the suction circuit for air inlets. Also, inspect the main tank cover valves to ensure the tank is not airproof.

Why the manometer pressure increases in KUHN Omnis?
- M
  Megan ScottAug 26, 2025
  If the pressure on the manometer of your KUHN Paint Sprayer increases, the tank return flow might be too low, so open the recycling valve. Another cause could be a clogged tank return tube, so clean the tube and ensure there are no foreign bodies. Also, check the flowmeter axial flow impeller rotation and replace the flowmeter if it's faulty.

  samanthafuentesAug 27, 2025
  If you observe foam formation in your KUHN Paint Sprayer, it might be due to air inlet during suction, so check the suction circuit. Excessive agitation can also cause this, so reduce the PTO speed, consider using an antifoam product, and open the recycling valve.

Why is outer suction difficult in KUHN Omnis Paint Sprayer?
- A
  ashley38Aug 30, 2025
  If you're experiencing difficult outer suction with your KUHN Paint Sprayer, check for a crushed or punctured suction tube and replace it if necessary. Ensure the suction tube isn't too long (maximum height: 3 m (9’10’’)). If there's limited pump backflow, open the flow regulation valve. If there's no water in the suction tube, clean the suction tube check valve and prime the pump with the rinsing tank.

Why the pressure varies when a section is shut-off in KUHN Omnis?
- T
  Terry RichardsonSep 1, 2025
  If the pressure varies when a section is shut-off in your KUHN Paint Sprayer, the calibrated return settings might be incorrect. Adjust the calibrated returns. For models fitted with a standard 3-way or 3-way semi-continuous circulation. Fully tighten the calibrated returns.

Why there is no unfolding/folding in KUHN Omnis Paint Sprayer?
- J
  Jessica MeyerSep 5, 2025
  If your KUHN Paint Sprayer experiences no unfolding/folding, check the plug voltage (12 V) for a faulty electric power supply. Also, check the tractor pressure and hydraulic flow for a faulty hydraulic power supply. Clean expansion plugs if the restrictor is clogged. Replace the fuse(s) if blown.

Why KUHN Omnis boom is fully raised as soon as the tractor valve is activated?
- J
  Joseph BishopSep 9, 2025
  If the boom is fully raised as soon as the tractor valve is activated on your KUHN Paint Sprayer, it could be due to incorrect oil input, so invert the hydraulic valve direction of action. Also, excessive return pressure can cause this, so connect the free return to the tractor tank.
