Schwintek slides
I too was new to Schwintek slides, so I did what I always do: I went on YouTube and Thor forums (previously we owned a Coachmen Leprechaun, so I went to their user forums).
I have a 24-foot Schwintek slide. It helped me to understand their operation. There are two motors that turn geared wheels to move the slide in and out. That's why you don't lubricate the track. These motors must operate in synch with one another or your slide will be crooked and could jam.
The motors are designed in a way that the operator can synch them up. By holding the slide extension button for a few seconds after the motors stop working, with the slide either fully extended or retracted. Technically, you could hold the button all day; it wouldn't hurt anything. What you're listening for are the motors talking to each other to synchronize before the next use.
Slides have rubber seals inside and outside the rig that help keep the outside outside. Like all rubber seals on an RV, they can get dry and crack. Use a rubber lubricant for all rubber seals.
Behind and at the top of the seals running down the side of your slide are the motors. Pull the seal back with your fingers to see the motors. If your slide ever gets out of synch and locks up, this is your first stop.
These motors are designed to disengage, allowing you to push the slide in or out. At the bottom of these motors is a bearing. Twice a year or more, use lubricant to lubricate this bearing.
The schwinteck track itself can be wiped down with vinegar and water, but be sure never to lubricate it.
I hope this in useful.
