Happijac 4500 - How to lubricate the Happijac

Hi friends
I created this how-to video for anyone who has a camper with a Happijac 4500. I ran into a problem on my own camper where the jacks seized up due to lack of lubrication. The manufacturer recommends drops of oil on the top of the jack and this video clearly shows how that will not work. I created this video to show you how to get around this and potentially save yourself time and money.
