How To Manually Retract Lippert Jacks

Many RVers rely on Lippert leveling jacks to stabilize their homes on wheels. However, situations can arise where automatic retraction fails. Knowing how to manually retract these jacks is crucial for getting back on the road. This guide provides a step-by-step approach to manually retracting Lippert leveling jacks, empowering you to handle these situations confidently.

Identifying Your Lippert Jack System

Before attempting any manual retraction, determine the type of Lippert leveling system installed on your RV. Common types include hydraulic and electric systems. Hydraulic systems typically have a central hydraulic pump and reservoir, while electric systems feature individual motors at each jack.

Preparing for Manual Retraction

Safety is paramount. Ensure the RV is on relatively level ground and properly chocked to prevent any movement. Wear safety glasses and gloves to protect yourself from potential debris or hydraulic fluid.

Gathering Necessary Tools

You'll likely need the following tools:

• A socket wrench with sockets that fit the manual override on your Lippert jacks (sizes vary, so have a selection).
• A screwdriver (both flathead and Phillips head may be needed).
• A wrench suitable for opening bleed valves (typically on hydraulic systems).
• A jack stand (if you need to relieve pressure or fully retract a stubborn jack).
• Hydraulic fluid (for topping off the reservoir in hydraulic systems after bleeding).
• Rags or shop towels (to clean up spills).

Manually Retracting Hydraulic Lippert Jacks

These steps detail how to retract hydraulic Lippert jacks.

Locating the Hydraulic Pump and Manifold

The hydraulic pump is usually located in a storage compartment. Identify the manifold, which houses the valves controlling each jack.

Identifying the Solenoid Valves

Each jack has a corresponding solenoid valve on the manifold. These valves control the flow of hydraulic fluid to and from the jacks.

Finding the Manual Override or Bleed Valve

Locate the bleed valve on each jack. It is usually a small screw or fitting. Have a rag ready as fluid will escape.

Opening the Bleed Valve

Carefully open the bleed valve on the jack you want to retract. Loosen it slowly. You should hear a hissing sound as the hydraulic pressure releases. The jack should begin to retract. Close the valve once the jack is fully retracted or stops retracting on its own.

Sometimes, gravity alone won't fully retract the jack. In this case, you may need to gently push up on the jack foot with a long object, or use a jack stand to relieve some pressure. Never position yourself directly under the jack without adequate support.

Checking the Hydraulic Fluid Level

After retracting the jacks, check the hydraulic fluid level in the reservoir. Top off if necessary with the recommended type of hydraulic fluid.

Manually Retracting Electric Lippert Jacks

Follow these steps to manually retract electric Lippert jacks.

Locating the Motor and Gearbox

Each electric jack has a motor and gearbox assembly. This is typically found on top of the jack itself.

Finding the Manual Override

Look for a manual override feature, often a bolt or fitting on the motor or gearbox. Some models have a specific point where you can insert a wrench or socket.

Using the Manual Override

Using the correct size socket wrench, turn the manual override in the direction that retracts the jack. It may take several turns. Be patient and apply steady pressure.

Electric jacks can be very slow to retract manually, especially if the motor is faulty or the gears are binding.

Troubleshooting Electric Jack Retraction

If the jack is not retracting using the manual override, try the following:

Check for Obstructions: Inspect the jack and surrounding area for any obstructions that may be preventing retraction. Check the Wiring: Inspect the wiring to the jack motor for any loose connections or damage. Use a Jack Stand: If the jack is under significant load, using a jack stand to relieve some pressure can make manual retraction easier.

Dealing with a Stubborn Jack

Sometimes, a jack may be particularly stubborn and difficult to retract manually. Here's how to handle such situations:

Apply Penetrating Oil

Spray penetrating oil on the jack's moving parts, especially the threaded rod or piston. This can help loosen any rust or corrosion that may be causing the jack to bind.

Rock the RV Gently

With someone spotting, gently rock the RV back and forth. This can help to free the jack and allow it to retract.

Use a Jack Stand Strategically

Position a jack stand under the jack foot to relieve some of the pressure. This can make manual retraction easier, especially for electric jacks. Be sure the jack stand is securely positioned on a solid surface.

Post-Retraction Inspection

After retracting the jacks manually, inspect them thoroughly for any signs of damage or wear. Check for leaks (especially in hydraulic systems), bent components, or loose connections. Schedule a professional inspection if you notice anything concerning.

It's also crucial to understand why the automatic retraction failed in the first place. A faulty pump, solenoid valve, motor, or control panel could be the culprit. Addressing the underlying issue prevents future manual retraction scenarios.

Preventive Maintenance

Regular maintenance can minimize the chances of encountering manual retraction problems.

• Hydraulic Systems: Check the hydraulic fluid level regularly and top off as needed. Inspect the lines and fittings for leaks. Consider changing the hydraulic fluid periodically.
• Electric Systems: Inspect the wiring and connections for corrosion or damage. Lubricate the jack's moving parts as recommended by the manufacturer.
• All Systems: Keep the jacks clean and free from debris. Periodically cycle the jacks up and down to ensure they are functioning properly.

Checklist for Manual Jack Retraction

Use this checklist to ensure a safe and effective manual jack retraction process.

• Safety First: RV chocked and on level ground.
• Gather Tools: Socket wrench, screwdriver, wrench (if hydraulic), jack stand, hydraulic fluid (if hydraulic), rags.
• Identify System: Hydraulic or electric.
• Hydraulic Systems: Locate pump, manifold, solenoid valves, and bleed valves. Open bleed valve slowly. Check and top off hydraulic fluid.
• Electric Systems: Locate motor, gearbox, and manual override. Use socket wrench to turn override. Check wiring.
• Stubborn Jacks: Apply penetrating oil, rock RV gently, use jack stand strategically.
• Post-Retraction: Inspect jacks for damage or wear. Identify the cause of the automatic failure. Schedule professional inspection if needed.
