Epitaph:
Schwintex Slide Mechanism
The only info on lubrication from Lippert is the video in this thread.
CRC Power Lube with PTFE is the MFG recommend lubricant.
Lubrication is not required for warranty to be valid
The slide typically does not fail due to lubrication. No recommended periodic lubrication.
There is no Thor or Lippert guidance on lubrication, except the video. Some say Lippert doesn't recommend it.
Videos on troubleshooting, controller override closure, and manual closing can be found on the LCI website as well as manuals:
