Back seat wont stay up

The latches can stick try spraying some lithium grease around the latches

Pull the handle as if the seat were installed and you were going to move it forward or back. They will slid back and forth on the seat so you can align the holes. set both sides even once you get the correct line up. After you put in front or rear 2 bolts then slide seat to install the other 2. Hope this helps Mike

check your tension springs one may be missing

Most of the seat backrest adjustments I have seen are via a strap attached to each side of the backrest uprights with a quick connect buckle and/or a slide through buckle like on a backpack, photo attached. maybe you could make something like this out of a old school bag strap. good luck. be safe :-)

You are missing one of the steps in your threading pattern. Sometimes it is going the wrong direction when threading the machine. Check your owners manual or go on line to the manufactures website and it will give you tips on what to do.

I had the same issue, my son used his all of half a day and the elevator stopped working. If you take the top of the cave off, and unscrew it from the elevator shaft you will see a black wheel. The string needs to be wrapped around this twice, there should be very little play in the string. What I had to do was take out the 3 screws that held it to the knob on top, then wrap the string back around the wheel making sure not to tangle the string more. once the string is wrapped 2 times you can reassemble.

The part below the guard is designed to come off for cleaning and restringing, as long as you still have all the parts, you just need to put it back together and it will be fine.

You are missing pinch roller lock, its like piece of plastic tube 2 or 3mm (1/8 inch)
This part is not available individually as you need to purchase complete "pinch roller assy" and fixing it requires skills and experience of camera repair.

You should make sure the cable is plugged into the video port on the back of the tower. Also, if you have more than one video card, ie an "onboard card" and another card that was added later, try alternating one to the other and see if the other one works. You can identify video ports by finding the blue pentagonal plug. It also will be the only plug that your monitor cable fits into (that is describing a VGA cable, a white cable is a DVI cable and is even easier to identify.) You might also want to make sure the video card wasnt jostled out of place. The final solution could be you have developed some bad memory modules, or the memory was jostled out of its slot during the move.

2 clips go in top center on back. one clip on each side by handle swivel points. also there is a string you thread underneath th front. Hope that helps
