Why is my Stihl Paint Sprayer spraying unit vibrating?
- JJennifer CollinsSep 3, 2025
If the spraying unit of your Stihl Paint Sprayer vibrates and the pressure gauge oscillates, the pulsation damper on the pump may not be working correctly. To address this, switch off the sprayer and remove the battery. Empty the container, then reinsert the battery and switch the sprayer back on. Press the trigger of the spray gun for 30 seconds, and then refill the container.
