Please consult the online manual for your saw
here, and review
this article about changing the blade.
All I can say is, You're not the only one, Thank God they finally changed the design of the blade change mechanism, How could it have taken that long for a bunch of German engineers to figure that one out, and you have my sympathy for owning one of those that use neither a screwdriver nor the new quick release mechanism.
Realise to begin with that the blade goes in and slips out in a position about 45 - 90 degrees away from the position it's in when cutting. In other words, the teeth must be turned somewhat to the side of the saw to allow the blade to slip free. Before that can happen, however, you must use that ridiculous handle mechanism to loosen the lock screw that holds the blade in place. First set the orbital selection switch to III or max orbit position. This will give you a little more flex when pulling the blade free. You might also pull the blade out to a more downward position if it's up inside the saw quite a bit. Pull up on the handle as shown in the instructions and rotate counterclockwise (looking down at the top of the saw) to loosen the blade, being careful not to pull up on the handle too much when it is exactly 180 degrees from the home position, or it will come off in your hand. That is the position to reinsert it in when it comes off, then turn it a little to the side to pull up again. I don't have much use for the push upward and pull downwards advice they give, regarding the tabs on the blade itself. It seems to me they could have figured out a way to keep the handle on the saw while you pull up on it to loosen and tighten the blade in place, but I guess with patience you can get it back in and tightened up again.turning what should be a thirty second blade change into a frustrating ordeal. The older model used a special long shank flat head screwdrive, which worked fine, but everyone would lose the screwdriver or forget to bring it to the jobsite, and without it you couldn't change the blade in that one either. Once you get the blade in they work great!
Anyway, know you're not alone when you curse Bosch, and someday you can replace that little pain for an upgraded model that has a 3 point support mechanism and much better blade change mechanism, or you could go all out and buy a Festo jigsaw, that you would love for the rest of your days...
Sorry for the rant. I hope that helps. I see that you wrote about a month ago, so hopefully you managed to cut your wood by now.
