Understanding the Importance of Bleeding Yale Sit-Down Hydraulic Lift Hoses


When it comes to hydraulic lifts, ensuring their proper functioning is crucial for both safety and performance. One essential maintenance task for hydraulic lifts, such as the Yale Sit-Down lift, is bleeding the hydraulic lift hoses. Bleeding the hoses removes any excess air trapped inside, allowing the system to operate efficiently.


In this article, we will delve into the steps required to bleed a Yale Sit-Down lift hydraulic lift hose effectively. We will explain why bleeding is necessary and provide you with a detailed guide to complete this task successfully.


The Purpose of Bleeding Hydraulic Lift Hoses


Before proceeding with the bleeding process, it is vital to understand why it is necessary. Over time, air can enter the hydraulic system through various means, including maintenance procedures like hose replacements or repairs. Additionally, air bubbles can form due to leaks or improper maintenance practices.


When air bubbles are present in the hydraulic system, they can disrupt the flow of hydraulic fluid. This can result in reduced lift performance, increased wear and tear on components, and potential safety hazards. Therefore, bleeding the hydraulic lift hoses is essential to eliminate air bubbles and ensure optimal functioning of the lift.


Gathering the Tools and Equipment


To bleed the hydraulic lift hoses of your Yale Sit-Down lift, you will need a few tools and equipment. Here's a list of necessary items:


1. Safety equipment: Always prioritize safety by wearing protective gloves and eye goggles.

2. Wrenches or pliers: These tools will be required to loosen and tighten various hydraulic fittings.

3. Container: Prepare a suitable container to collect any excess hydraulic fluid that may be released during the bleeding process.

4. Bleed kit: Optional, but a bleed kit can make the process more manageable with specialized tools designed for bleeding hydraulic systems.


Locating the Bleeder Valve and Preparing for Bleeding


To begin, you need to locate the bleeder valve. The bleeder valve is typically situated near the hydraulic lift cylinder or control valve. Refer to the Yale Sit-Down lift's user manual or consult a professional for specific instructions if needed.


Next, you should ensure the lift is in a safe and stable position. Lower the lift to the ground if necessary, and secure it to prevent any accidental movement during the bleeding procedure. Additionally, inspect the hydraulic hoses for any visible signs of damage or leaks that should be repaired before bleeding.


Bleeding the Yale Sit-Down Hydraulic Lift Hoses


1. Begin by loosening the bleeder valve with a wrench or pliers, allowing air and fluid to escape. Gradually open the valve, taking care not to loosen it too much. Position the container beneath to catch any released fluid.


2. Depress the lift's control pedal or lever that operates the hydraulic system. By doing so, you will initiate the flow of hydraulic fluid through the hoses, effectively forcing out any trapped air bubbles.


3. Continue to operate the control pedal or lever for approximately 10-15 seconds. As you do this, keep a close eye on the fluid flow and listen for any unusual noises. If any air bubbles are still present, they should be released and visible within the collected fluid.


4. Once you are confident that most of the air bubbles have been expelled, close the bleeder valve firmly. Ensure it is not overtightened to avoid damaging the valve or surrounding components.


Closing Thoughts


Bleeding the hydraulic lift hoses of your Yale Sit-Down lift is a crucial maintenance task that should not be overlooked. By following the steps outlined in this guide, you can ensure optimal performance, extend the lifespan of your hydraulic lift hoses, and maintain a safe working environment.


Regularly inspecting and bleeding the hydraulic lift hoses will contribute to the smooth operation of your Yale Sit-Down lift, providing reliable lifting and lowering capabilities for years to come. Remember to consult the manufacturer's guidelines and seek assistance from professionals if you encounter any difficulties during the bleeding process.
