Bleeding the hydraulic cylinder.
Air can enter the hydraulic system at any time its components are opened for service. Symptoms of air in the
system include erratic or bouncing motion of the platform, sponginess in holding position, unusual noises, or
foaming in the hydraulic fluid. Trapped air can also trigger the cylinder’s velocity fuse, slowing or preventing the
cylinder from lowering.
Cycling the platform up and down without a load can expel much of the trapped air through the hydraulic
reservoir. If it becomes necessary to bleed air from the system:
1. Remove any load from the platform.
2. Raise the platform. Lower the maintenance props into the side frame. Lower the platform until the
props are about ½”-1” away from the end of the frame. Some motion is necessary to expel air from the
system.
3. Hold a rag over the bleeder valve of the cylinders to capture expelled oil. Bleeder valves are located at
the top of each cylinder (see below 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. There is a cylinder attached to each leg set and each
cylinder has a bleeder valve. It is recommended the 2 people, 1 on each cylinder, work together to bleed
air from the system.
