Michelin jack won't lift a load - 09/23/18 06:32 AM
Hi all. I have a 3 1/2 ton Michelin floor jack that has the quick lift feature but it has now rendered itself useless. It will raise and lower itself without any weight on it but anything like a car is out of the question. It will just stay under the car and squeak loudly with every pump. There are 3 screws behind the pump cylinder and I don't want to risk adding more air into what I suspect isn't the oil fill plug. In fact they say "DO NOT ADJUST" around these 3 plugs and this isn't something I want to mess up completely. How can I bleed the air out thoroughly?
