Mom has a Stanna 420 Stairlift that has worked well until very recently when it began to groan. I know it needs lubrication but I don't know which lubricant to use nor do I know where to apply the lubricant. We're located in the U.S. and I would very much appreciate guidance on this issue. Thank you.
