OK sorry I can't I answer you question no experience with those guys,but I just wanted to comment.The only dumb question is the un-asked question. Especially here,it won't be long and someone will be able to help you with that problem.Sorry I can't.
Hi Barry Jnr There is a little Horse Shoe shaped Cir clip just below the spring It holds the spring and washer in place. If you use a srew driver you should be able to pop this off. The spring and washer will then become loose. Then you can just wind the height adjustment handle all the way off.
