Hello, Jayne - welcome to the forum. If you look here: https://www.hilotrailerforum.com/f49...2001-hi-lo-23/
you'll find the owner's manual for the 2001 HiLos. HiLo did not change the trailers very much from year to year and each year had a "generic" owner's manual that covered all the models made then. I think you'll find that the manual I pointed you to will cover yours.
