leaking hydraulic jack

Hey guys, a driver at work has this 3 ton canadian tire jack that we all have been using for a year and a half now. It is starting to leak some oil on the ground and today since it was warm I jacked up the yaris to locate the plugs for the engine oil and tranny oil as I want to get familiar with the location. Anyways he is giving the jack to me for free and wondering how hard or how costly would it be to repair? I think I have the knowledge to repair it but I need you guys on rfd for some guidance. :)

You most likely have to change the seals on the jack's slave cylinder. If you don't know what you are doing it might get dangerous, since the jack won't hold pressure, therefore weight.

They are basically non repairable. What I mean is, if you took it to a machine shop and had them disassemble it and then order seals for it and put it back together, you may as well go buy another one.
As for now, if it leaks, don't use it and for sure don't lay under the car unless you have jack stands under the car. do not rely on the jack to hold your car up.
Is it solipsistic here? Or is it just me?

A lot of them leak a bit. If it's low on oil, it just won't lift as high. Just don't go near the car till it's on jack stands, leaking or not.

I would spend a couple bucks on some oil to fill it back up and try using it. Fill it back up, wipe of any excess drips off the bottom side and see if it continues to leak.
Again, do not get under the vehicle without jack stands.

I bought two orings, two flat Teflon wahsers and repaired it for under 15 bucks. The oil from CT was 10 bucks.

Lmfao. Thanks for the update. For the first time in two years I can finally get a good nights sleep knowing your hydraulic jack is back in order!
