I've thrown my hydraulic jack in the trash!! (lol),. Wow, this jack lifts so fast!! Like in no more than "5 seconds" my 01 Ranger is lifted and I can slide my jack stand under and get to work!! Well worth the $$$ folks! The only downside compared to the hydraulic jack is that you need a compressor "but" you already know this if your looking at this jack. It is a game changer for lifting time (no more pumping!!) and jack placement but because it has a 6-8" wide rubber pad to lift your vehicle and not the little 2.5" pad on my hydraulic !! Just make sure the lift point is straight and vertically under the jack and NOT angled under whatever lifting area point you are using. No assembly instructions, just feed air line thru straight handle first then the 4 flat head Philips screws go under the big jack plate (the heads face/touch the ground) and nuts go on top of handle's plate. The 2 Allen bolts are to lock the round bent handle to the straight handle. Remaining 2 Philips and nuts lock the controls to the plate on the bent handle.PEOPLE....for safety sakes "ALWAYS" use jackstand(s) with this and any air type jack!! If you own a shop get this jack !! If your like me, a driveway/weekend mechanic get this jack !!
