I have leakage as well at the bottle when I don't close the valve firmly and not loaded.
It should not be leaking at all, but just a few extra drops of oil helps it when I "forget" to close it.
But for the price it should not be happening. Still for me the J&S jacks is what I prefer. They way it goes controlled down is amazing. With my previous Harbor freight my bike went down shocking and got myself always worried when the bike would eventually fall off.

 

Love mine! Love it!

 

LOL !!!! like to buy you a shot and a beer! Lol

 

Nice AM drama thread...went from J&S Jack QC issue to competitor jack wars & then bottle jack/dick swinging fight...thanks for the entertainment.

OP; Keep us posted on your progress/outcome w/J&S...curious owners want to know - thks!

 

My J&S failed also. However, it doesn't appear to be the bottle jack leaking. It's an air assist model. The jack will lift the bike, but after it sits for a while in the locked position, it will not lift the bike out of the locks.

J&S is working with me. They've sent me emails on bleeding and filling the jack.

 

My table lift has that system, I had to replace the springs and check ***** in 2 ports to cure it. The china ones the springs were flimsy & weak and the steel ***** weren't perfectly round you feel flats on them.

 

That sure is a nice handle on the release valve.. I wonder if it will fit my Jack.

My J&S is a few years old and came with an Omega Jack, Chinese. Imo, Omega brand is better than the lesser Chinese brands. Mine is still holding up fine...

 

They have a great warranty . So don't let the little things in life get ya rattled. They will
send you a new bottle and all will be good. Now if I had to ride the jack then I would get mad.

 

I've had my J&S for about 5 years now and it's been trouble free, knock on wood. But I warned that sumbitch when I got it to never fail on me or there would be hell to pay. I recommend this approach.

 

Buying a premium jack in "kit form" doesn't sound too swell. Hopefully they will send you a new, carefully inspected unit with a pre-paid return shipping label for the old one. Then at the factory, they can find out everything that went wrong with your particular unit and get onto inspector number 12.
