At first I wasn't going to post this due to my bruised ego but I thought it might serve some other first time users out there.
So this past weekend I decided to rotate my tires using my welded sliders and my hi lift jack. I was also going to banging out the front fenders for a little more tire clearance.
So I chock the driver side wheels and use two jack stands while I hammer away and switched the passenger side tires. Everything went well and then it was time to switch sides and lower the hi lift.
This was the first time the jack has ever had a heavy load on it and it would not lower. After almost 45 mins of lubricating and researching the very simple lowering process I could not figure out why it would not lower.
Long story short I had to push down on the handle hard to activate the ratcheting mechanism of the jack. As I was not prepared for this specific action/reaction the jack caught me off gaurd and the handle slipped out of my hands.
This left just open air between the handle of the jack and my head. Wack into the side of the head. 2 days later and a visit to the doctors I'm suffering from a mild concussion. Happen so fast that there was not even a moment that I could have reacted after my hands slipped.
I watched several video's and read the instructions before using it and from what I can gather; is that a newly coated hi lift jack can cause the pins to stick and in general do not funtion as well as a broken in jack.
I'm not pointing the finger at anybody but me in this case as I usually seem to find the hardest way to learn something.
My advice to any other first time users out there is when lowering the jack pull from underneath the handle so that if it does slip out of your hands, you are not in the way.
