Yesterday I lifted my Ford Edge onto the QJ 5000 SLX to do a routine oil change. Because it is an SUV and sits high, I use a double stack block on each pad - the bottom is the larger block, and the top is the grooved block to fit the underside jack point of the vehicle. My understanding from the instructions is that this method is acceptable. I then use jack stands as a back up. Sometimes I do no bother, for instance when I lift the 911 to the low position only.
Anyway, lifted the car to the highest position. Pushed on it to make sure everything was secure, like I always do, then crawled under and started to put the jack stands in. I set one under the first front point, and the moment I set the second one under the drivers side, something shifted and the whole thing almost came down on me. Holy Effen Christee I damn near crapped myself but got out fast. Had the jack stand not been under there, it would have been on me and I would not be typing this.
I looked at everything - the double stack block arrangement shifted, and the blocks popped out on one side, and failed on the other. The frame itself shifted, and the back of the car was hanging in the air by a literal hair, just waiting to fall. I gathered my wits then got my two floor jacks, and after some very careful manuevering, got the car down (the front jack stands were jammed on the car at this point, so I had to re-lift it with the QJ in order to get the stands out and lower the car - not fun and scary).
Moral of the story - ALWAYS, 100% OF THE TIME, USE JACK STANDS AS A FAIL SAFE WHEN WORKING UNDER A CAR WITH THE QUICKJACK (or anything else frankly). I have done this many times and this was a first. I do not know why it happened. I much prefer my liftbars for the 928 and 997, as they are rock solid and lift those cars about as high, and are much faster to put in place.
Epilogue - I got the vehicle back up with the QJ, using only the grooved blocks, no double stacking, and was able to complete the job. Fail safe jack stands were in place all around.
