    How to fix leakage through the cylinder upper part of Jacto Paint Sprayer?
    • T
      Tanya FordJul 27, 2025
      Leakage through the cylinder upper part is often caused by a worn or dried out piston cup. You can fix this by replacing or lubricating the piston cup.

    Why is the Jacto HD-400 lever hard to pump and the spray stops rapidly?
    • H
      Holly JenkinsAug 4, 2025
      If the lever is hard to pump and the spray stops rapidly, it is likely due to air leaking through the nut that fastens the hose to the chamber. To resolve this, drain all the liquid from the chamber and then tighten the nut.

    • B
      billy84Aug 12, 2025
      If the lever drops after pumping and pressurizing the chamber, it indicates that the cylinder valve is not sealing properly. This can be due to wear or impurities. You should clean or replace the valve to fix this issue.

    • F
      frederick95Aug 19, 2025
      If the lever rises slowly when released after pumping and pressurizing the chamber, it is because the chamber valve is not sealing properly. This is likely due to wear or impurities. Cleaning or replacing the valve should solve the problem.
