    Symptom = The Zenith Hylo Adjusting Table will struggle to raise fully and it will be extra noisy to raise.

    Problem=  Air has gotten trapped inside the main hydraulic cylinder,hoses and tank. This is because the hydraulics fluid has ran low and the Zenith Hylo Table was raised. This could be  because the cylinder is going bad and leaking, or a line has ruptured or has loosened up from vibration.

    Think of the Table as it was a Car.


    When the table is raised up (System is pressurized), it’s like having the car running!


    So,Always try to lower your Zenith Hylo Table (System is DE-Pressurized) before going to lunch, and before you leave at night. 


    Doing this helps extend the life of your Zenith Chiropractic Hylo Tables Hydraulics!!!
