Thanks you Elroy and Hiball for your timely responses.
It sounds like I will need to get a new bag of kitty litter before I fill the thing or maybe I will wait until the wife is out and hijack a cake pan.
I realize i can tighten the spanner nut with a punch but then I wouldn't have any need to...
Should the jack be on its wheels or should the cylinder be vertical when adding the oil?
After its been filled, how do I go about bleeding air from the cylinder?
I guess I will check ebay for spanner wrenchs. Do you know of another source? I am unfamiliar with the sizing of spanner wrenches...
Re: Filling Hein Warner Floor Jack model WS
Elroy, my congratulations on your excellent pictorial on rebuilding the Hein Werner WS on OS jacks.
I ran across it as I was searching for information on the proper method of filling my model WS.
I had it rebuilt a few years ago, kept it as a backup...
