Lift placement

I’m not sure if you bought hydraulic oil or not, but I bought a 5 gallon bucket of CAM 2 AW32 from Menards for pretty cheap. You only need 3-4 gallons so you’ll have some extra. My lift has been up and working for almost 2 years now without issue.

I haven’t bought fluid yet. I did however stand the columns up over the weekend. Does the fluid need to be changed yearly?
