Hydraulic Slide Will Not Extend Completely

On a hydraulic slide out system by Lippert there are not any “limit switches” in the system... the components would be...

.. hydraulic solenoid valve...
.. Hig( pressure cutoff switch

If you hold the extend or retract button in the slides will move in or out to full position and hydraulic pressure will build and activate the high pressure limit switch which in turn shuts off the hyd pump motor

You need to download the thru the frame Lippert slide out manual and there is a section that will show and guide you thru how to adjust the travel on the slides...

Each slide has an adjustment for extend and retract travel...

One has loosened up and slide is out of adjustment. ....Or something is in the way of that slideout preventing it from extending completely

Operate one limit switch and see which slide stops.

I have access to the limiter switch. I don't know which one it is, as the pump operates two slides simultaneously. Suggestions?

Thanks David

Have you checked the hydraulic fluid reservoir to make sure it is full?

If you can get to the slide mechanism look for a travel limit switch, which may need to be adjusted.
