Bleeding Air from the Hydraulic Cylinder(s).
Air can enter the hydraulic system any time it is opened for servicing. Symptoms of air in the system
include jerky or bouncy motion of the platform, platform sponginess (lowers a bit when a load is applied),
unusual noises, or foamy hydraulic fluid. Trapped air can also trigger the integral velocity fuse which can
retard or prevent cylinder retraction.
Cycling the platform up and down without a load can expel much of the trapped air through the
hydraulic reservoir. If air needs to be bled from the system:
1. Unload the platform.
2. Raise the platform by pressing the LIFT RAISE button. Deploy the maintenance stops. Lower the platform
until the ends of the props are ½”-1” away from the corners of the base frame. The platform must not be
supported by the props because some motion is necessary to expel air from the system.
3. Hold a rag over the cylinder’s bleeder valve to capture expelled oil. The valve is located at the top of
the cylinder (see illustration). Use a ¼” wrench to open the valve about a half-turn.
4. Oil and air will sputter from the valve. Once no more air comes out, close the valve.
5. For multi-cylinder lift tables, it will be necessary to open the bleeder valves on all cylinders simultaneously
in order to bleed the valves.
Lower the platform until the ends of the
maintenance props are 1”-1
