How do you bleed hyd auto lift?

To bleed the hydraulic system of an auto lift, start by raising the lift to its maximum height. Then, locate the bleed valve, which is usually found near the hydraulic cylinder or pump. Open the valve slowly while keeping the lift in position, allowing any trapped air to escape until a steady stream of hydraulic fluid flows out without bubbles. Finally, close the valve securely and check the fluid level, topping it off if necessary.
