      williamstonyAug 26, 2025
      If your Jacto Paint Sprayer is spraying intermittently, it could be due to an improperly adjusted pressure switch. To resolve this, remove the sprayer base cover and use an Allen wrench no. 2 to adjust the pump pressure switch. Also, try replacing the hydraulic tip with one of the tips provided with the sprayer or a hydraulic tip with a greater flow rate.

    What to do if Jacto DJB-20S panel turns on but the pump doesn't work?
    • A
      Allison CookAug 30, 2025
      If the electronic panel of your Jacto Paint Sprayer turns on, but the pump isn't working, start by removing the cover of the sprayer base and checking the connection between the electronic panel and the pump, as well as the connection between the electronic panel and the trigger valve. If the trigger valve cable is damaged (broken, uncovered), replace the complete trigger valve. Also, if the trigger valve orange protections are damaged and electronic components are exposed, replace the trigger valve.

    What to do if Jacto DJB-20S was spraying normal, but stopped suddenly?
    • D
      David CohenSep 2, 2025
      If your Jacto Paint Sprayer suddenly stops spraying after working normally, the issue could stem from several causes. Ensure you are using a JACTO original battery to avoid overvoltage. If the battery is completely discharged, charge it until the charge light turns green. Press the green button until the pressure drops and clean the nozzle and filters. Check the trigger valve and pump wiring.

    What to do if Jacto DJB-20S panel turns on, pump turns on, but there is no spraying?
    • M
      millsstevenSep 5, 2025
      If the panel and pump of your Jacto Paint Sprayer are on, but there's no spraying, check for obstructions in the hydraulic system. Ensure the filters are clean, the tank suction hole is not clogged, and there are no folded hoses. Also, verify the correct assembly of the nozzle diffuser, ensuring the hydraulic tip diffuser pin is facing towards. You can also try positioning a hose with running water on the sprayer suction hole with the sprayer at maximum pressure and the trigger valve pushed for a few seconds.

    Why Jacto DJB-20S charger green light turns on, but the battery is not charged?
    • P
      Pamela PatelSep 12, 2025
      If the green light on your Jacto Paint Sprayer charger turns on, but the battery isn't charging (the light color doesn't change when the battery is connected), it could be due to poor contact in the battery connection. Make sure the plug is fully inserted into the battery connector.
