How do I fold my jogger (The Twinner II-16). I bought it used without a manual. Can manuals be located on the internet? Thanks

There are 4 pins that need to be pulled. 1st Flip the stroller over and remove the 2 back wheels...sqeeze the metal piece by the wheel and pull the wheel straight out. Pull the 1st 2 pins, they are between the back wheels and the front wheel, on either side. The bars these were holding in place will swing up. Then pull the 2 front pins (by the front wheel) and flip the front tire up. The front wheel also comes off but isn't neccesary.
