    How to fix Stihl Paint Sprayer when there is no spray from nozzle?

      Joseph AguirreJul 27, 2025
      If your Stihl Paint Sprayer isn't spraying from the nozzle, it's likely that the hose and wand system is blocked. To fix this, rinse and clean all parts of the hose and wand system with clean water. This includes the spray gun, the filter in the handle, the spray wand, and the hose itself.

      If the pumping action on your Stihl Paint Sprayer isn't producing any pressure, it could be due to no suction. You should fit a new O-ring on the piston. Also, check that the balls in the pump housing are properly seated and not sticking.

      If the lever of your Stihl Paint Sprayer falls down under its own weight, it indicates that the ball (intake side) is sticking. To resolve this, remove the hose from the bottom of the pump housing and take out the ball. Clean the ball and make sure it moves freely.

      If the lever of your Stihl Paint Sprayer moves upwards on its own, the ball (delivery side) is likely sticking. To fix this, open the screw plug in the pump housing and take out the ball. Clean the ball and ensure it moves freely.
