Mine definitely slows down at the very bottom of it's travel and I have used my foot to push it down on occasion. Didn't think much of it though....

Add high grade hydraulic fluid (sold separately) slowly until the fluid reaches 1/4â€³ below the top of the Fill Port.
while one says
Add high grade hydraulic fluid into the fill hole slowly until the fluid reaches the top of the hole.
I have a fairly new Harbor Freight 4 ton floor jack. Occasionally I have to put some weight on it to get it to fully come down. I was attributing it to the possibility that the Jack needed to break in a bit. I'm wondering if that is the case now. The Jack functions perfectly otherwise.
