The video demonstrates how to bleed air from a hydraulic circuit, which is essential for proper functioning. The process involves locating and utilizing the bleed port or fitting.
Unfortunately, the provided context gives generic information about bleeding air from a hydraulic circuit. To provide a specific procedure for bleeding an air hydraulic pump, I would need more details such as the pump's manufacturer and model number. However, based on common practices, here's a generalized approach:
- Identify the Bleed Port: Look for a screw, fitting, or valve specifically designated as a bleed port on the air hydraulic pump. According to the video, this could be a fitting cap or plug.
- Prepare the Area: Clean the area around the bleed port to prevent contaminants from entering the hydraulic system.
- Loosen the Bleed Port: Carefully loosen the bleed port. The video mentions that some fittings do not have an elastomeric seal, like a JIC fitting, therefore extra care may be needed.
- Operate the Pump: Manually actuate the pump handle or lever. This will force hydraulic fluid through the system and push air out of the bleed port.
- Observe the Fluid: Watch the fluid emerging from the bleed port. Initially, you may see air bubbles. Continue pumping until a steady stream of air-free fluid flows out.
- Tighten the Bleed Port: Once all the air is bled, tighten the bleed port to the manufacturer's specified torque. Do not overtighten, as this could damage the fitting.
- Test the Pump: Operate the pump to ensure it is functioning correctly and that there are no signs of air in the system.
