Manual Slide-Out System Override: Easy Steps to Follow

There might be situations when you need to take control of the slide-out system manually. In this section, I will guide you through the process of manually overriding the system, offering step-by-step instructions for both the outside and inside frames. Let’s begin!

Outside Frame

This extension is located on the outer side of the main chassis rail. Follow these steps to operate the slide-out manually:

  • Step 1: Find the crank extension with the pin on the outer side of the chassis rail. This is where the crank handle connects for manual extension and retraction of the slide-out room.
  • Step 2: To retract the slide-out, turn the crank handle in a clockwise direction. For extension, turn it counterclockwise (opposite direction).

Inside Frame

When you’re inside your RV, you can manually control the slide-out system using the actuator’s top hex head crank extension inside the chassis main frame. Follow these steps:

  • Step 1: Look for the hex head crank extension on top of the actuator inside the main frame of the chassis.
  • Step 2: To retract the slide-out, rotate the extension in a clockwise direction using a 3/4” socket and ratchet. For extension, turn it counterclockwise.
Pro Tip: Whether you’re using the outside or inside frame method, it’s necessary to remember that the system is designed to allow for manual control without disconnecting the motor. This means you can engage the manual override without the need for complicated motor disconnection procedures.

4 Important Safety Considerations

In situations where professional assistance might not be readily available, it’s valuable to have some basic slide-out repair knowledge. Ensuring safety during slide-out maintenance is crucial to prevent accidents. Remember these essential safety practices:

4 Important Safety Considerations
  • Park on Level Ground: When working with your slide-out system, ensure that your RV is parked on a surface that is both level and stable. If possible, use a leveling tool to make sure your RV is properly balanced. This provides a safe foundation for any maintenance tasks.
  • Switch Off and Disconnect: Before you begin inspecting or working on the slide-out system, make sure the slide-out is switched off. Additionally, disconnect the battery from the RV’s electrical system. This precaution helps prevent any accidental movements or electrical mishaps while you’re working.
  • Ensure Clear Space: Prior to operating the slide-out system, check to make sure that no one is close to the slide-out room, whether inside or outside the RV. This prevents the risk of someone getting caught or injured as the slide-out moves.
  • Travel with Tools: It’s a good idea to keep a power drill with a hex-knot adapter handy during your travels. This tool will be invaluable for manual override situations. The manual override system operates with a turn gear ratio of about 200 to 1. This means that for every inch you want to move the slide in or out, you might need to crank the manual valve around 200 times.


How do you manually operate a Lippert slide-out?

To manually operate a Lippert slide-out, look for a switch inside your camper. It might be on the wall or near the slide-out. Then, press the switch to the “Extend” or “Out” position. This tells the slide-out to move outwards. As you press the switch, the slide-out will start moving.
