Help with Hein Werner

[splat]

Hey guys/gals...been a while since I've been here. Couldn't find an answer to my question although I'm sure it's here somewhere.
I've had 2 of these jacks....one I sold here on the site some years ago...and this one. I purchased 1 of them new in about 1985...I think it's this one.
Anyway, after some years of battling health issues I'm starting to get back into the garage...and needed the jack. Can someone tell me where the fill hole is for fluid? I've bled it off but it's not reaching max height. I know I've checked it before but it's probably been 30 years...and now. I feel like an idiot stick not being able to locate it. With my health still an issue, just getting it up on the work bench is a challenge....grandson helps when available. TIA for any help with this.

Looks like this might provide the answer:
Where to fill my Hein-Werner 1-1/2 jack?

Glad you're back in the garage - enjoy!

Mine is at the handle end of the jack. The rear cover flips up. I stand it up on it’s front wheels and remove the plug with a 1/2” wrench and use a squirt bottle like a mustard bottle to get the oil into the 5/16” hole. Give it time to bleed off air as you fill.

Do not use brake fluid as it is supposedly bad for the seals. I have used automatic transmission fluid in my jacks for the last 40 years.

Thanks guys....I'll take a look today and see if I can locate the screw.

Found the fill hole...now to see if I can get hydraulic oil in it.

I use a meat injector syringe without the needle. Works well.

Okay....I have another question. So under that plate is the filler screw/hole. So I've added fresh hydraulic fluid. I want to bleed and an online manual I found years ago says leave that screw out and pump the jack 6-8 times then reinstall the screw and you are good to go.
Elsewhere in the manual it says if you need to add or replace oil it says to remove the " air vent" screw. So, I only see 2 screws. One I've included a pic of. It's on the top, screwed flush with the top. I show it removed.
The other screw is under that plate that flips forward....it's a round screw, flat head, with a gasket. This is where I added the oil. I did that cause someone here had sent the link above in this thread...and that thread showed a pic of that screw as the filler hole.
So my question...which is the " vent screw" and is the screw under the plate that flips the filler screw? I'm not even going to try bleeding until I'm sure which is which. TIA

Thanks man....I used something like you recommended.....

Not 100% sure, but imagine the "air vent" means to have the bleeder screw (that you use to lower the jack) open. Have it open a pump the jack 5 to 15 times, then jack as high as you can. Repeat as needed. Also you can close the bleeder and manually lift the seat as far as it will go, put your foot on it and open the bleeder to flush the valve. Do that a few times then air bleed.

Okay......I will give both those methods a shot. Neither of those 2 methods can cause any harm. I'd even read somewhere to leave the fill hole screw out....and lift the saddle by hand while pumping fluid into the fill hole. The writer said that doing that will **** fluid into the system and air will be flushed. But I didn't understand " where " the air would be purged out....
Anyway, thanks.....I'll try that and see if it does the job....
