In that article I mention that you don’t need to do any inner maintenance of the chair, i.e. lube jobs, like you have to do with a car. However, there are times when certain parts of a chair can squeak and in that particular case you may need to a little “greasing.”
This happens very rarely, but we’ve seen it enough that I thought it would be a good topic of discussion. Every chair is different and has different “greasing points”, but there are some similarities. I am going to give you the instructions that were given to us by Infinite Therapeutics when we had a local IT-8500 that had begun to squeak. This is a pretty good guideline for most chairs.
My son, Rob, does all of our local repairs and he says that it is very easy to grease the pivot points. I would suggest that if you have squeaking coming from any part of your massage chair, call the manufacturer first and find out what they suggest. If it needs greasing, they will send you pivot point locations and instructions. Here is an example of what the pivot points are in the Infinity IT-8500:
1.the back of the recliner (for zero gravity, footrest, backrest lifting)
2.the pin roll of the recliner and the connection for the recliner hangers
3.the connection between the backrest and seat stand
4.the footrest recliner pushing rollers and spout
5.the connection between the footrest and seat stand
Pretty simple stuff, eh?
