Welcome to the Forum!
Congratulations on your 'NEW' Hi-Lo.
Here is a link to many of the Hi-Lo brochures where you may find your model: http://www.hilotrailerforum.com/f52/...llection-5123/
I could not find your model in that year, but if you look you may find it.
If you scroll down on the main page to the library you will find manuals listed. You may not find your exact year, but the manuals change little from year to year and are not model specific. There is also a listing of video instructions on the operation of Hi-Lo trailers.
